Accounting Policies [Abstract]
Summary of Critical and Significant Accounting Policies	Summary of Critical and Significant Accounting Policies (a) Principles of Consolidation and Basis of Presentation The accounts of the Company, its controlled subsidiaries and the variable interest entities ("VIEs") in which it is the primary beneficiary are consolidated in the accompanying financial statements and prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP"). In the opinion of management, all adjustments necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented have been included and are normal and recurring in nature. All significant inter-company accounts and transactions have been eliminated. Noncontrolling interest includes the 3.4% limited partner interests in the Operating Partnership not held by the Company at both December 31, 2021 and 2020. These percentages include the Operating Partnership’s vested long-term incentive plan units (see Note 14). (b) Recently Adopted Accounting Pronouncements In January 2021, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2021-01 "Reference Rate Reform (Topic 848): Scope." The amendments in ASU No. 2021-01 provide optional expedients to the current guidance on contract modifications and hedge accounting from the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. The guidance generally can be applied to applicable contract modifications through December 31, 2022. The Company adopted this new guidance in January 2021 on a prospective basis. This adoption did not have a material impact on the Company's consolidated results of operations or financial position. (c) Recent Accounting Pronouncements In August 2020, the FASB issued ASU No. 2020-06 “Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity.” The amendments in ASU No. 2020-06 modifies the if-converted method of calculating diluted EPS. For instruments that may be settled in cash or shares, and are not classified as liability, the guidance requires entities to include the effect of potential share settlement in the diluted EPS calculation, if the effect is more dilutive. ASU No. 2020-06 is effective for the Company on January 1, 2022 and will be applied on a prospective basis. The Company does not expect this adoption to have a material impact on its consolidated results of operations or financial position. (d) Real Estate Rental Properties Significant expenditures, which improve or extend the life of an asset and have a useful life of greater than one year, are capitalized. Operating real estate assets are stated at cost and consist of land and land improvements, buildings and improvements, furniture, fixtures and equipment, and other costs incurred during their development, redevelopment and acquisition. Expenditures for maintenance and repairs are charged to expense as incurred. The depreciable life of various categories of fixed assets is as follows: Computer software and equipment 3 - 5 years Interior apartment home improvements 5 years Furniture, fixtures and equipment 5 - 10 years Land improvements and certain exterior components of real property 10 years Real estate structures 30 years The Company capitalizes all costs incurred with the predevelopment, development or redevelopment of real estate assets or are associated with the construction or expansion of real property. Such capitalized costs include land, land improvements, allocated costs of the Company’s project management staff, construction costs, as well as interest and related loan fees, property taxes and insurance. Capitalization begins for predevelopment, development, and redevelopment projects when activity commences. Capitalization ends when the apartment home is completed and the property is available for a new tenant or if the development activities cease. The Company allocates the purchase price of real estate on a fair value basis to land and building including personal property, and identifiable intangible assets, such as the value of above, below and in-place leases. In making estimates of relative fair values for purposes of allocating purchase price, the Company utilizes a number of sources, including independent land and building appraisals which consider comparable market transactions, its own analysis of recently acquired or developed comparable properties in our portfolio for land comparables and building replacement costs, and other publicly available market data. In calculating the fair value of identified intangible assets of an acquired property, the in-place leases are valued based on in-place rent rates and amortized over the average remaining term of all acquired leases. The values of the above and below market leases are amortized and recorded as either a decrease (in the case of above market leases) or an increase (in the case of below market leases) to rental revenue over the remaining term of the associated leases acquired. The value of acquired in-place leases are amortized to expense over the average remaining term of the leases acquired. The net carrying value of acquired in-place leases is $8.9 million and $4.7 million as of December 31, 2021 and 2020, respectively, and are included in prepaid expenses and other assets on the Company's consolidated balance sheets. The Company periodically assesses the carrying value of its real estate investments for indicators of impairment. The judgments regarding the existence of impairment indicators are based on monitoring investment market conditions and performance compared to budget for operating properties including the net operating income for the most recent 12 month period, monitoring estimated costs for properties under development, the Company's ability to hold and its intent with regard to each asset, and each property's remaining useful life. Whenever events or changes in circumstances indicate that the carrying amount of a property held for investment may not be fully recoverable, the carrying amount is evaluated. If the sum of the expected future cash flows (undiscounted and without interest charges) is less than the carrying amount (including intangible assets) of a property held for investment, then the Company will recognize an impairment loss equal to the excess of the carrying amount over the fair value of the property. Fair value of a property is determined using conventional real estate valuation methods, such as discounted cash flow, the property’s unleveraged yield in comparison to the unleveraged yields and/or sales prices of similar communities that have been recently sold, and other third party information, if available. Communities held for sale are carried at the lower of cost or fair value less estimated costs to sell. As of December 31, 2021, no properties were classified as held for sale. As of December 31, 2020, two properties were classified as held for sale. The Company did not record an impairment charge for the year ended December 31, 2021. The Company recorded an impairment charge of $1.8 million for the year ended December 31, 2020 related to one of the Company's consolidated properties as a result of a change in the Company's intent to hold the property for its remaining useful life. The Company recorded an impairment charge of $7.1 million for the year ended December 31, 2019 on a parcel of land that was part of a consolidated co-investment with Canada Pension Plan Investment Board ("CPPIB" or "CPP"). The impairment charge resulted from the Company's acquisition of CPPIB's 45% interest in the co-investment. The impairment analysis over the parcel’s fair value was determined using internally developed models based on market assumptions. In the normal course of business, the Company will receive purchase offers for its communities, either solicited or unsolicited. For those offers that are accepted, the prospective buyer will usually require a due diligence period before consummation of the transaction. It is not unusual for matters to arise that result in the withdrawal or rejection of the offer during this process. The Company classifies real estate as "held for sale" when the Company has obtained necessary management approvals to sell a property and the sale of the property is expected to be completed within a year. Evaluating solicited or unsolicited offers generally does not cause properties to be classified as held for sale. (e) Co-investments The Company owns investments in joint ventures in which it has significant influence, but its ownership interest does not meet the criteria for consolidation in accordance with U.S. GAAP. Therefore, the Company accounts for co-investments using the equity method of accounting. Under the equity method of accounting, the investment is carried at the cost of assets contributed, plus the Company’s equity in earnings less distributions received and the Company’s share of losses. The significant accounting policies of the Company’s co-investment entities are consistent with those of the Company in all material respects. Upon the acquisition of a controlling interest of a co-investment, the co-investment entity is consolidated and a gain or loss is recognized upon the remeasurement of co-investments in the consolidated statement of income equal to the amount by which the fair value of the Company's previously owned co-investment interest exceeds its carrying value. A majority of the co-investments, excluding most preferred equity investments, compensate the Company for its asset management services and some of these investments may provide promote income if certain financial return benchmarks are achieved. Asset management fees are recognized when earned, and promote fees are recognized when the earnings events have occurred and the amount is determinable and collectible. Any promote fees are reflected in equity income from co-investments. The Company recorded an other-than-temporary impairment charge of $11.5 million for the year ended December 31, 2019 on an unconsolidated co-investment with CPPIB which held Agora, a 49-unit apartment home community located in Walnut Creek, CA. The other-than-temporary impairment charge resulted from the Company's acquisition of CPPIB's 45% interest in the co-investment. The impairment analysis over the co-investments fair value was determined using internally developed models based on market assumptions. The impairment is reflected in equity income from co-investments on the consolidated statements of income. No other-than-temporary impairment charges were recorded for the years ended December 31, 2021 or 2020. (f) Revenues and Gains on Sale of Real Estate and Land Revenues from tenants renting or leasing apartment homes are recorded when due from tenants and are recognized monthly as they are earned, which generally approximates a straight-line basis, else, adjustments are made to conform to a straight-line basis. Apartment homes are rented under short-term leases (generally, lease terms of 9 to 12 months). Revenues from tenants leasing commercial space are recorded on a straight-line basis over the life of the respective lease. See Note 4, Revenues, and Note 10, Lease Agreements - Company as Lessor, for additional information regarding such revenues. The Company also generates other property-related revenue associated with the leasing of apartment homes, including storage income, pet rent, and other miscellaneous revenue. Similar to rental income, such revenues are recorded when due from tenants and recognized monthly as they are earned. Apart from rental and other property-related revenue, revenues from contracts with customers are recognized as control of the promised services is passed to the customer. For customer contracts related to management and other fees from affiliates (which includes asset management and property management), the transaction price and amount of revenue to be recognized is determined each quarter based on the management fee calculated and earned for that month or quarter. The contract will contain a description of the service and the fee percentage for management services. Payments from such services are one month or one quarter in arrears of the service performed. The Company recognizes any gains on sales of real estate when it transfers control of a property and when it is probable that the Company will collect substantially all of the related consideration. (g) Cash, Cash Equivalents and Restricted Cash Highly liquid investments with original maturities of three months or less when purchased are classified as cash equivalents. Restricted cash balances relate primarily to reserve requirements for capital replacement at certain communities in connection with the Company’s mortgage debt. The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the consolidated balance sheets that sum to the total of the same such amounts shown in the consolidated statements of cash flows ($ in thousands): 2021 2020 2019 Cash and cash equivalents - unrestricted $ 48,420 $ 73,629 $ 70,087 Cash and cash equivalents - restricted 10,218 10,412 11,007 Total unrestricted and restricted cash and cash equivalents shown in the consolidated statements of cash flows $ 58,638 $ 84,041 $ 81,094 (h) Marketable Securities The Company reports its equity securities and available for sale debt securities at fair value, based on quoted market prices (Level 1 for the common stock and investment funds, Level 2 for the unsecured debt and Level 3, as defined by the FASB standard for fair value measurements as discussed later in Note 2). As of December 31, 2021 and 2020, $0.8 million and $2.5 million, respectively, of equity securities presented within common stock and stock funds in the tables below represent investments measured at fair value, using net asset value as a practical expedient, and are not categorized in the fair value hierarchy. Any unrealized gain or loss in debt securities classified as available for sale is recorded as other comprehensive income. There were no other than temporary impairment charges for the years ended December 31, 2021, 2020, and 2019. Unrealized gains and losses in equity securities, realized gains and losses in debt securities, interest income, and amortization of purchase discounts are included in interest and other income on the consolidated statements of income. As of December 31, 2021 and 2020, equity securities and available for sale debt securities consisted primarily of investment-grade unsecured debt, and common stock and stock funds. As of December 31, 2021 and 2020, marketable securities consist of the following ($ in thousands): December 31, 2021 Amortized Gross Carrying Equity securities: Investment funds - debt securities $ 62,192 $ (502) $ 61,690 Common stock and stock funds 79,155 49,592 128,747 Debt securities: Available for sale Investment-grade unsecured debt 1,051 341 1,392 Total - Marketable securities $ 142,398 $ 49,431 $ 191,829 December 31, 2020 Amortized Gross Carrying Equity securities: Investment funds - debt securities $ 49,646 $ 985 $ 50,631 Common stock and stock funds 81,074 15,001 96,075 Debt securities: Available for sale Investment-grade unsecured debt 1,050 12 1,062 Total - Marketable securities $ 131,770 $ 15,998 $ 147,768 The Company uses the specific identification method to determine the cost basis of a debt security sold and to reclassify amounts from accumulated other comprehensive income for such securities. For the years ended December 31, 2021, 2020 and 2019, the proceeds from sales and maturities of marketable securities totaled $16.6 million, $113.5 million and $147.5 million, respectively. For the years ended December 31, 2021, 2020 and 2019, these sales resulted in gains of $3.4 million, $2.1 million, and $1.3 million, respectively. For the years ended December 31, 2021 and 2020, the portion of equity security unrealized gains recognized in income totaled $33.1 million and $12.5 million in gains, respectively, and were included in interest and other income on the Company's consolidated statements of income and comprehensive income. (i) Notes Receivable Notes receivable relate to real estate financing arrangements including mezzanine and bridge loans. Interest is recognized over the life of the note as interest income. Each note is analyzed to determine if it is impaired. A note is impaired if it is probable that the Company will not collect all contractually due principal and interest. The Company does not accrue interest when a note is considered impaired and an allowance is recorded for any principal and previously accrued interest that are not believed to be collectible. All cash receipts on impaired notes are applied to reduce the principal amount of such notes until the principal has been recovered and, thereafter, are recognized as interest income. As of December 31, 2021 and 2020, no notes were impaired. In the normal course of business, the Company originates and holds two types of loans: mezzanine loans issued to entities that are pursuing apartment development and short-term bridge loans issued to joint ventures with the Company. The Company categorizes development project mezzanine loans into risk categories based on relevant information about the ability of the borrowers to service their debt, such as: current financial information, credit documentation, public information, and previous experience with the borrower. The Company initially analyzes each mezzanine loan individually to classify the credit risk of the loan. On a periodic basis the Company evaluates and performs site visits of the development projects associated with the mezzanine loans to confirm whether they are on budget and whether there are any delays in development that could impact the Company's assessment of credit loss. All bridge loans that the Company issues are, by their nature, short-term and meant only to provide time for the Company’s joint ventures to obtain long-term funding for newly acquired communities. As the Company is a partner in the joint ventures that are borrowing such funds and has performed a detailed review of each community as part of the acquisition process, there is little to no credit risk associated with such loans. As such, the Company does not review credit quality indicators for bridge loans on an ongoing basis. The Company estimates the allowance for credit losses for each loan type using relevant available information from internal and external sources, relating to past events, current conditions, and reasonable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made, if necessary, for differences in current loan-specific risk characteristics. For example, in the case of mezzanine loans, adjustments may be made due to differences in track record and experience of the mezzanine loan sponsor as well as the percent of equity that the sponsor has contributed to the project. (j) Capitalization Policy The Company capitalizes all direct and certain indirect costs, including interest, employee compensation costs, real estate taxes and insurance, incurred during development and redevelopment activities. Interest is capitalized on real estate assets that require a period of time to get them ready for their intended use. The amount of interest capitalized is based upon the average amount of accumulated development expenditures during the reporting period. Included in capitalized costs are management’s estimates of the direct and incremental personnel costs and indirect project costs associated with the Company's development and redevelopment activities. Indirect project costs consist primarily of personnel costs associated with construction administration and development, including accounting, legal fees, and various corporate and community onsite costs that clearly relate to projects under development. Those costs, inclusive of capitalized interest, as well as capitalized development and redevelopment fees totaled $23.6 million, $31.4 million and $42.1 million for the years ended December 31, 2021, 2020 and 2019, respectively, most of which relates to development projects. The Company capitalizes leasing costs associated with the lease-up of development communities and amortizes the costs over the life of the leases. The amounts capitalized are immaterial for all periods presented. (k) Fair Value of Financial Instruments The Company values its financial instruments based on the fair value hierarchy of valuation techniques described in the FASB’s accounting standard for fair value measurements. Level 1 inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 inputs include quoted prices for similar assets and liabilities in active markets and inputs other than quoted prices observable for the asset or liability. Level 3 inputs are unobservable inputs for the asset or liability. The Company uses Level 1 inputs for the fair values of its cash equivalents and its marketable securities except for unsecured bonds and mortgage backed securities. The Company uses Level 2 inputs for its investments in unsecured debt, notes receivable, notes payable, and derivative assets/liabilities. These inputs include interest rates for similar financial instruments. The Company’s valuation methodology for derivatives is described in Note 9. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. Management believes that the carrying amounts of the outstanding balances under its lines of credit, and notes and other receivables approximate fair value as of December 31, 2021 and 2020, because interest rates, yields and other terms for these instruments are consistent with interest rates, yields and other terms currently available for similar instruments. Management has estimated that the fair value of fixed rate debt with a carrying value of $5.7 billion and $5.5 billion at December 31, 2021 and 2020, respectively, to be $6.0 billion at both December 31, 2021 and 2020. Management has estimated the fair value of the Company’s $564.9 million and $775.1 million of variable rate debt at December 31, 2021 and 2020, respectively, to be $561.7 million and $770.1 million at December 31, 2021 and 2020, respectively, based on the terms of existing mortgage notes payable, unsecured debt, and variable rate demand notes compared to those available in the marketplace. Management believes that the carrying amounts of cash and cash equivalents, restricted cash, accounts payable and accrued liabilities, construction payables, other liabilities and dividends payable approximate fair value as of December 31, 2021 and 2020 due to the short-term maturity of these instruments. Marketable securities are carried at fair value as of December 31, 2021 and 2020. (l) Interest Rate Protection, Swap, and Forward Contracts The Company uses interest rate swaps, interest rate caps, and total return swap contracts to manage interest rate risks. The Company’s objective in using derivatives is to add stability to interest expense and to manage its exposure to interest rate movements or other identified risks. To accomplish this objective, the Company uses interest rate swaps as part of its cash flow hedging strategy. The Company records all derivatives on its consolidated balance sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. For derivatives designated for accounting purposes as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in earnings. For derivatives designated for accounting purposes as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (outside of earnings) and subsequently reclassified to earnings when the hedged transaction affects earnings, and the ineffective portion of changes in the fair value of the derivative is recognized directly in earnings. The Company assesses the initial and ongoing effectiveness of each hedging relationship by comparing the changes in fair value or cash flows of the derivative hedging instrument with the changes in fair value or cash flows of the designated hedged item or transaction. For derivatives not designated for accounting purposes as cash flow hedges, changes in fair value are recognized in earnings. All of the Company’s interest rate swaps are considered cash flow hedges. (m) Income Taxes Generally in any year in which Essex qualifies as a real estate investment trust ("REIT") under the Internal Revenue Code (the "IRC"), it is not subject to federal income tax on that portion of its income that it distributes to stockholders. No provision for federal income taxes, other than the taxable REIT subsidiaries discussed below, has been made in the accompanying consolidated financial statements for each of the years in the three-year period ended December 31, 2021 as Essex has elected to be and believes it qualifies under the IRC as a REIT and has made distributions during the periods in amounts to preclude Essex from paying federal income tax. In order to maintain compliance with REIT tax rules, the Company utilizes taxable REIT subsidiaries for various revenue generating or investment activities. The taxable REIT subsidiaries are consolidated by the Company. In general, the activities and tax related provisions, assets and liabilities are not material. As a partnership, the Operating Partnership is not subject to federal or state income taxes, except that in order to maintain Essex's compliance with REIT tax rules that are applicable to Essex, the Operating Partnership utilizes taxable REIT subsidiaries for various revenue generating or investment activities. The taxable REIT subsidiaries are consolidated by the Operating Partnership. The status of cash dividends distributed for the years ended December 31, 2021, 2020, and 2019 related to common stock are classified for tax purposes as follows: 2021 2020 2019 Common Stock Ordinary income 70.92 % 85.23 % 83.81 % Capital gain 22.07 % 10.68 % 13.78 % Unrecaptured section 1250 capital gain 7.01 % 4.09 % 2.41 % 100.00 % 100.00 % 100.00 % (n) Equity-based Compensation The cost of share- and unit-based compensation awards is measured at the grant date based on the estimated fair value of the awards. The estimated fair value of stock options and restricted stock granted by the Company are being amortized over the vesting period. The estimated grant date fair values of the long-term incentive plan units (discussed in Note 14) are being amortized over the expected service periods.

Realized gains and losses on available for sale debt securities are included in interest and other income on the consolidated statements of income. (p) Redeemable Noncontrolling Interest The carrying value of redeemable noncontrolling interest in the accompanying balance sheets was $34.7 million and $32.2 million as of December 31, 2021 and 2020, respectively. The limited partners may redeem their noncontrolling interests for cash in certain circumstances. The changes in the redemption value of redeemable noncontrolling interests for the years ended December 31, 2021, 2020, and 2019 are as follows: 2021 2020 2019 Balance at January 1, $ 32,239 $ 37,410 $ 35,475 Reclassifications due to change in redemption value and other 6,890 (4,299) 2,008 Redemptions (4,463) (872) (73) Balance at December 31, $ 34,666 $ 32,239 $ 37,410 (q) Accounting Estimates The preparation of consolidated financial statements, in accordance with U.S. GAAP, requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosures of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to acquiring, developing and assessing the carrying values of its real estate portfolio, its investments in and advances to joint ventures and affiliates, and its notes receivable. The Company bases its estimates on historical experience, current market conditions, and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may vary from those estimates and those estimates could be different under different assumptions or conditions. (r) Variable Interest Entities In accordance with accounting standards for consolidation of VIEs, the Company consolidated the Operating Partnership, 18 DownREIT entities (comprising nine communities), and six co-investments as of December 31, 2021. The Company consolidated the Operating Partnership, 17 DownREIT entities (comprising nine communities), and five co-investments as of December 31, 2020. The Company consolidates these entities because it is deemed the primary beneficiary. The Company has no assets or liabilities other than its investment in the Operating Partnership. The consolidated total assets and liabilities related to the above consolidated co-investments and DownREIT entities, net of intercompany eliminations, were approximately $909.3 million and $320.1 million, respectively, as of December 31, 2021, and $898.5 million and $326.8 million, respectively, as of December 31, 2020. Noncontrolling interests in these entities were $122.4 million and $120.8 million as of December 31, 2021 and 2020, respectively. The Company's financial risk in each VIE is limited to its equity investment in the VIE. The DownREIT VIEs collectively own nine apartment communities in which the Company is the general partner or manager of the DownREIT entity, the Operating Partnership is a special limited partner or member, and the other limited partners or members were granted rights of redemption for their interests. Such limited partners or members can request to be redeemed and the Company, subject to certain restrictions, can elect to redeem their rights for cash or by issuing shares of its common stock on a one share per unit basis. Conversion values will be based on the market value of the Company's common stock at the time of redemption multiplied by the number of units stipulated under various arrangements, as noted above. The other limited partners or members receive distributions based on the Company's current dividend rate times the number of units held. Total DownREIT units outstanding were 978,854 and 1,017,460 as of December 31, 2021 and 2020, respectively, and the redemption value of the units, based on the closing price of the Company’s common stock totaled approximately $344.8 million and $241.6 million, as of December 31, 2021 and 2020, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities The Company uses interest rate swaps, interest rate caps, and total return swap contracts to manage certain interest rate risks. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. The fair values of interest rate swaps and total return swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In November 2016, the Company replaced its $225.0 million term loan with a $350.0 million five As of December 31, 2021 and 2020, the Company had no interest rate caps. As of December 31, 2021 and 2020, the aggregate carrying value of the interest rate swap contracts were a liability of zero and an asset of $2.4 million, respectively. As of December 31, 2021 and 2020, the swap contracts were presented in the consolidated balance sheets as a liability of zero and $2.4 million, respectively, and were included in other liabilities on the consolidated balance sheets. The Company had no interest rate caps on the balance sheets as of December 31, 2021 and 2020. Hedge ineffectiveness related to cash flow hedges, which is included in interest expense on the consolidated statements of income, was zero, zero, and a loss of $0.2 million for the years ended December 31, 2021, 2020, and 2019 respectively. The Company has four total return swap contracts, with an aggregate notional amount of $224.4 million, that effectively convert $224.4 million of mortgage notes payable to a floating interest rate based on the Securities Industry and Financial Markets Association Municipal Swap Index ("SIFMA") plus a spread. The total return swaps provide fair market value protection on the mortgage notes payable to our counterparties during the initial period of the total return swap until the Company's option to call the mortgage notes at par can be exercised. The Company can currently call all four of the total return swaps with $224.4 million of the outstanding debt at par. These derivatives do not qualify for hedge accounting and had a carrying and fair value of zero at both December 31, 2021 and 2020, respectively. These total return swaps are scheduled to mature between November 2022 and December 2024. The realized gains of $10.8 million, $10.7 million, and $8.4 million as of December 31, 2021, 2020, and 2019, respectively, were reported on the consolidated statements of income as total return swap income.

Leases [Abstract]
Lease Agreements - Company as Lessor	Lease Agreements - Company as Lessor As of December 31, 2021, the Company is a lessor of apartment homes at all of its consolidated operating and lease-up communities, three commercial buildings, and commercial portions of mixed use communities. The apartment homes are rented under short-term leases (generally, lease terms of 9 to 12 months) while commercial lease terms typically range from 5 to 20 years. All such leases are classified as operating leases. Although the majority of the Company’s apartment home and commercial leasing income is derived from fixed lease payments, some lease agreements also allow for variable payments. The primary driver of variable leasing income comes from utility reimbursements from apartment home leases and common area maintenance reimbursements from commercial leases. A small number of commercial leases contain provisions for lease payments based on a percentage of gross retail sales over set hurdles. At the end of the term of apartment home leases, unless the lessee decides to renew the lease with the Company at the market rate or gives notice not to renew, the lease will be automatically renewed on a month-to-month term. Apartment home leases include an option to terminate the lease, however the lessee must pay the Company for expected or actual downtime to find a new tenant to lease the space or a lease-break fee specified in the lease agreement. Most commercial leases include options to renew, with the renewal periods extending the term of the lease for no greater than the same period of time as the original lease term. The initial option to renew for commercial leases will typically be based on a fixed price while any subsequent renewal options will generally be based on the current market rate at the time of the renewal. Certain commercial leases contain lease termination options that would require the lessee to pay termination fees based on the expected amount of time it would take the Company to re-lease the space. The Company’s apartment home and commercial lease agreements do not contain residual value guarantees. As the Company is the lessor of real estate assets which tend to either hold their value or appreciate, residual value risk is not deemed to be substantial. Furthermore, the Company carries comprehensive liability, fire, extended coverage, and rental loss insurance for each of its communities as well as limited insurance coverage for certain types of extraordinary losses, such as, for example, losses from terrorism or earthquakes. A maturity analysis of undiscounted future minimum non-cancelable base rent to be received under the above operating leases as of December 31, 2021 is summarized as follows ($ in thousands): Future Minimum Rent 2022 $ 681,245 2023 23,932 2024 18,749 2025 16,293 2026 12,934 Thereafter 34,016 $ 787,169 Practical Expedients The Company has elected to account for operating lease (e.g., fixed payments including rent) and non-lease components (e.g., utility reimbursements and common-area maintenance costs) as a single combined lease component under ASC 842 "Leases" as the lease components are the predominant elements of the combined components.

Lease Agreements - Company as Lessee	Lease Agreements - Company as LesseeAs of December 31, 2021, the Company is a lessee of corporate office space, ground leases and a parking lease associated with various consolidated properties, and equipment. Lease terms for the Company's office leases, in general, range between 5 to 10 years while ground leases and the parking lease have terms typically ranging from 20 to 85 years. The corporate office leases occasionally contain renewal options of approximately five years while certain ground leases contain renewal options that can extend the lease term from approximately 10 to 39 years. A majority of the Company’s ground leases and the parking lease are subject to changes in the Consumer Price Index ("CPI"). Furthermore, certain of the Company’s ground leases include rental payments based on a percentage of gross or net income. While lease liabilities are not remeasured as a result of changes in the CPI or percentage of gross or net income, such changes are treated as variable lease payments and recognized in the period in which the obligation for those payments was incurred. The Company’s lease agreements do not contain any residual value guarantees or restrictive covenants. Operating lease right-of-use assets and operating lease liabilities are recognized based on the present value of lease payments over the lease term at commencement date. Because most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. As of December 31, 2021 and 2020, the Company had no material finance leases. Supplemental consolidated balance sheet information related to leases as of December 31, 2021 and 2020 is as follows ($ in thousands): Classification December 31, 2021 December 31, 2020 Assets Operating lease right-of-use assets Operating lease right-of-use assets $ 68,972 $ 72,143 Total leased assets $ 68,972 $ 72,143 Liabilities Operating lease liabilities Operating lease liabilities $ 70,675 $ 74,037 Total lease liabilities $ 70,675 $ 74,037 The components of lease expense for the years ended December 31, 2021 and 2020 were as follows ($ in thousands): December 31, 2021 December 31, 2020 Operating lease cost $ 6,729 $ 6,749 Variable lease cost 1,639 1,436 Short-term lease cost 287 432 Sublease income (438) (438) Total lease cost $ 8,217 $ 8,179 A maturity analysis of lease liabilities as of December 31, 2021 is as follows ($ in thousands): Operating Leases 2022 $ 6,987 2023 6,962 2024 6,690 2025 6,310 2026 4,440 Thereafter 135,977 Total lease payments $ 167,366 Less: Imputed interest (96,691) Present value of lease liabilities $ 70,675 Lease term and discount rate information for leases at December 31, 2021 and 2020 are as follows: December 31, 2021 December 31, 2020 Weighted-average of remaining lease terms (years) Operating Leases 40 39 Weighted-average of discount rates Operating Leases 5.01 % 5.00 % Practical Expedients Leases with an initial term of 12 months or less are not recorded on the balance sheet. The Company recognizes the lease expense for such leases on a straight-line basis over the lease term. The Company has elected to account for lease components (e.g., fixed payments including rent) and non-lease components (e.g., common-area maintenance costs) as a single combined lease component as the lease components are the predominant elements of the combined components.

Equity [Abstract]
Equity Transactions	Equity Transactions Common Stock Offerings In September 2021, the Company entered into a new equity distribution agreement pursuant to which the Company may offer and sell shares of its common stock having an aggregate gross sales price of up to $900.0 million (the "2021 ATM Program"). In connection with the 2021 ATM Program, the Company may also enter into related forward sale agreements, and may sell shares of its common stock pursuant to these agreements. The use of a forward sale agreement would allow the Company to lock in a share price on the sale of shares of its common stock at the time the agreement is executed, but defer receipt of the proceeds from the sale of shares until a later date should the Company elect to settle such forward sale agreement, in whole or in part, in shares of its common stock. For the year ended December 31, 2021, the Company did not sell any shares of its common stock through the 2021 ATM Program or through the 2018 ATM Program. For the year ended December 31, 2020, the Company did not sell any shares of its common stock through the 2018 ATM Program. For the year ended December 31, 2019, the Company issued 228,271 shares of common stock through the 2018 ATM Program at an average price of $321.56 per share for proceeds of $73.4 million. As of December 31, 2021, there are no outstanding forward sale agreements, and $900.0 million of shares remain available to be sold under the 2021 ATM Program. Operating Partnership Units and Long-Term Incentive Plan ("LTIP") Units As of December 31, 2021 and 2020, the Operating Partnership had outstanding 2,176,327 and 2,188,623 OP Units respectively. As of both December 31, 2021 and 2020 the Operating Partnership had 106,137 vested LTIP units. The Operating Partnership’s general partner, Essex, owned 96.6% of the partnership interests in the Operating Partnership as of both December 31, 2021 and 2020, and Essex is responsible for the management of the Operating Partnership’s business. As the general partner of the Operating Partnership, Essex effectively controls the ability to issue common stock of Essex upon a limited partner’s notice of redemption. Essex has generally acquired OP Units upon a limited partner’s notice of redemption in exchange for shares of its common stock. The redemption provisions of OP Units owned by limited partners that permit Essex to settle in either cash or common stock at the option of Essex were further evaluated in accordance with applicable accounting guidance to determine whether temporary or permanent equity classification on the balance sheet is appropriate. The Operating Partnership evaluated this guidance, including the requirement to settle in unregistered shares, and determined that, with few exceptions, these OP Units meet the requirements to qualify for presentation as permanent equity. LTIP units represent an interest in the Operating Partnership for services rendered or to be rendered by the LTIP unitholder in its capacity as a partner, or in anticipation of becoming a partner, in the Operating Partnership. Upon the occurrence of specified events, LTIP units may over time achieve full parity with common units of the Operating Partnership for all purposes. Upon achieving full parity, LTIP units will be exchanged for an equal number of the OP Units. The collective redemption value of OP Units and LTIP units owned by the limited partners, not including Essex, was approximately $804.0 million and $544.8 million based on the closing price of Essex's common stock as of December 31, 2021 and 2020, respectively.

Share-based Payment Arrangement, Noncash Expense [Abstract]
Equity Based Compensation Plans	Equity Based Compensation Plans Stock Options and Restricted Stock In May 2018, stockholders approved the Company’s 2018 Stock Award and Incentive Compensation Plan ("2018 Plan"). The 2018 Plan serves as the successor to the Company’s 2013 Stock Incentive Plan (the "2013 Plan"). The Company’s 2018 Plan provides incentives to attract and retain officers, directors and key employees. The 2018 Plan provides for the grant of stock-based awards to employees, directors and consultants of the Company and its affiliates. The aggregate number of shares of the Company’s common stock available for issuance pursuant to awards granted under the 2018 Plan is 2,000,000 shares, plus the number of shares authorized for grants and available for issuance under the 2013 Plan as of the effective date of the 2018 Plan and the number of shares subject to outstanding awards under the 2013 Plan that are forfeited or otherwise not issued under such awards. No further awards will be granted under the 2013 Plan and the shares that remained available for future issuance under the 2013 Plan as of the effective date of the 2018 Plan will be available for issuance under the 2018 Plan. In connection with the adoption of the 2018 Plan, the Board delegated to the Compensation Committee of the Board the authority to administer the 2018 Plan. Equity-based compensation costs for options and restricted stock under the fair value method totaled $11.7 million, $12.9 million, and $11.4 million for years ended December 31, 2021, 2020 and 2019, respectively. For each of the years ended December 31, 2021, 2020 and 2019 equity-based compensation costs included $3.5 million related to restricted stock for bonuses awarded based on asset dispositions, which is recorded as a cost of real estate and land sold, respectively. Stock-based compensation for options and restricted stock related to recipients who are direct and incremental to projects under development were capitalized and totaled $0.9 million, $1.3 million, and $1.6 million for the years ended December 31, 2021, 2020 and 2019, respectively. The intrinsic value of the options exercised totaled $25.7 million, $7.4 million, and $18.7 million, for the years ended December 31, 2021, 2020, and 2019 respectively. The intrinsic value of the options exercisable totaled $22.5 million and $3.4 million as of December 31, 2021 and 2020, respectively. Total unrecognized compensation cost related to unvested stock options totaled $3.9 million as of December 31, 2021 and the unrecognized compensation cost is expected to be recognized over a period of 2.2 years. The average fair value of stock options granted for the years ended December 31, 2021, 2020 and 2019 was $24.68, $20.69 and $24.02, respectively. Certain stock options granted in 2021, 2020, and 2019 included a $100 cap, $100 cap, and, $125 cap on the appreciation of the market price over the exercise price. The fair value of stock options was estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions used for grants: 2021 2020 2019 Stock price $ 329.71 $ 244.74 $ 304.85 Risk-free interest rates 1.22 % 0.83 % 2.01 % Expected lives 6 years 6 years 6 years Volatility 27.00 % 25.72 % 19.56 % Dividend yield 2.90 % 2.93 % 2.72 % A summary of the status of the Company’s stock option plans as of December 31, 2021, 2020, and 2019 and changes during the years ended on those dates is presented below: 2021 2020 2019 Shares Weighted- Shares Weighted- Shares Weighted- Outstanding at beginning of year 613,109 $ 255.86 572,971 $ 251.10 612,954 $ 224.57 Granted 99,479 329.71 149,020 244.74 148,147 304.85 Exercised (248,725) 231.37 (70,802) 208.57 (182,817) 205.25 Forfeited and canceled — — (38,080) 228.64 (5,313) 257.87 Outstanding at end of year 463,863 284.82 613,109 255.86 572,971 251.10 Options exercisable at year end 274,244 270.11 361,985 245.83 305,379 223.90 The following table summarizes information about restricted stock outstanding as of December 31, 2021, 2020 and 2019 and changes during the years ended: 2021 2020 2019 Shares Weighted- Shares Weighted- Shares Weighted- Unvested at beginning of year 132,603 $ 214.34 114,877 $ 197.62 91,058 $ 180.99 Granted 50,349 337.52 45,196 248.16 41,643 235.93 Vested (22,387) 229.90 (15,116) 170.61 (13,222) 143.56 Forfeited and canceled (1,164) 219.30 (12,354) 184.11 (4,602) 158.06 Unvested at end of year 159,401 251.03 132,603 214.34 114,877 197.62 The unrecognized compensation cost related to unvested restricted stock totaled $14.4 million as of December 31, 2021 and is expected to be recognized over a period of 1.8 years. Long-Term Incentive Plans – LTIP Units On December 9, 2014, the Operating Partnership issued 44,750 LTIP units under the 2015 Long-Term Incentive Plan Award agreements to executives of the Company. The 2015 Long-Term Incentive Plan Units (the "2015 LTIP Units") are subject to forfeiture based on performance-based and service based conditions. An additional 24,000 LTIP units were granted subject only to performance-based criteria and were fully vested on the date granted. The 2015 LTIP Units, that are subject to vesting, vested at 20% per year on each of the first five In December 2013, the Operating Partnership issued 50,500 LTIP units under the 2014 Long-Term Incentive Plan Award agreements to executives of the Company. The 2014 Long-Term Incentive Plan Units (the "2014 LTIP Units") were subject to forfeiture based on performance-based conditions and are currently subject to service based vesting. The 2014 LTIP Units vested 25% per year on each of the first four ten The estimated fair value of the 2015 LTIP Units and 2014 LTIP Units were determined on the grant date using Monte Carlo simulations under a risk-neutral premise and considered Essex’s stock price on the date of grant, the unpaid dividends on unvested units and the discount factor for ten years of illiquidity. Prior to 2013, the Company issued Series Z Incentive Units and Series Z-1 Incentive Units (collectively referred to as "Z Units") of limited partnership interest in the Operating Partnership. Vesting in the Z Units is based on performance criteria established in the plan. The criteria can be revised by the Compensation Committee of the Board of Directors if the Committee deems that the plan's criterion is unachievable for any given year. The sale of Z Units is contractually prohibited. Z Units are convertible into Operating Partnership units which are exchangeable for shares of the Company’s common stock that have marketability restrictions. The estimated fair value of Z Units were determined on the grant date and considered the Company's stock price on the date of grant, the dividends that are not paid on unvested units and a marketability discount for the 8 to 15 years of illiquidity. Compensation expense is calculated by multiplying estimated vesting increases for the period by the estimated fair value as of the grant date. During 2011 and 2010, the Operating Partnership issued 154,500 Series Z-1 Incentive Units (the "Z-1 Units") of limited partner interest to executives of the Company. The Z-1 Units are convertible one-for-one into common units of the Operating Partnership (which, in turn, are convertible into common stock of the Company) upon the earlier to occur of 100 percent vesting of the units or the year 2026. The conversion ratchet (accounted for as vesting) of the Z-1 Units into common units, is to increase consistent with the Company’s annual FFO growth, but is not to be less than zero or greater than 14 percent. Z-1 Unitholders are entitled to receive distributions, on vested units, that are now equal to dividends distributed to common stockholders. Equity-based compensation costs for LTIP and Z Units under the fair value method totaled approximately zero, zero and $0.9 million for the years ended December 31, 2021, 2020 and 2019, respectively. Equity-based compensation costs related to LTIP Units attributable to recipients who are direct and incremental to these projects was capitalized to real estate under development and totaled approximately zero, zero, and $0.2 million, for the years ended December 31, 2021, 2020, and 2019, respectively. The intrinsic value of the vested and unvested LTIP Units totaled $37.4 million as of December 31, 2021. Total unrecognized compensation cost related to the unvested LTIP Units under the LTIP Units plans was zero as of December 31, 2021.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company's segment disclosures present the measure used by the chief operating decision makers for purposes of assessing each segment's performance. The Company's chief operating decision makers are comprised of several members of its executive management team who use net operating income ("NOI") to assess the performance of the business for the Company's reportable operating segments. NOI represents total property revenues less direct property operating expenses. The executive management team generally evaluates the Company's operating performance geographically. The Company defines its reportable operating segments as the three geographical regions in which its communities are located: Southern California, Northern California and Seattle Metro. Excluded from segment revenues and NOI are management and other fees from affiliates and interest and other income. Non-segment revenues and NOI included in the following schedule also consist of revenues generated from commercial properties and properties that have been sold. Other non-segment assets include items such as real estate under development, co-investments, real estate held for sale, cash and cash equivalents, marketable securities, notes and other receivables, and prepaid expenses and other assets. The revenues and NOI for each of the reportable operating segments are summarized as follows for the years ended December 31, 2021, 2020, and 2019 ($ in thousands): Years Ended December 31, 2021 2020 2019 Revenues: Southern California $ 588,381 $ 566,553 $ 593,253 Northern California 584,034 604,348 557,139 Seattle Metro 239,839 243,900 243,060 Other real estate assets 19,164 71,349 57,176 Total property revenues $ 1,431,418 $ 1,486,150 $ 1,450,628 Net operating income: Southern California $ 408,207 $ 391,095 $ 423,177 Northern California 401,862 431,124 412,706 Seattle Metro 160,954 166,847 172,601 Other real estate assets 15,136 56,684 45,617 Total net operating income 986,159 1,045,750 1,054,101 Management and other fees from affiliates 9,138 9,598 9,527 Corporate-level property management expenses (36,188) (34,573) (34,067) Depreciation and amortization (520,066) (525,497) (483,750) General and administrative (51,838) (65,388) (54,262) Expensed acquisition and investment related costs (203) (1,591) (168) Impairment loss — (1,825) (7,105) Gain (loss) on sale of real estate and land 142,993 64,967 (3,164) Interest expense (203,125) (220,633) (217,339) Total return swap income 10,774 10,733 8,446 Interest and other income 98,744 40,999 46,298 Equity income from co-investments 111,721 66,512 112,136 Deferred tax expense on unrealized gain on unconsolidated co-investment (15,668) (1,531) (1,457) (Loss) gain on early retirement of debt, net (19,010) (22,883) 3,717 Gain on remeasurement of co-investment 2,260 234,694 31,535 Net income $ 515,691 $ 599,332 $ 464,448 Total assets for each of the reportable operating segments are summarized as follows as of December 31, 2021 and 2020 ($ in thousands): As of December 31, 2021 2020 Assets: Southern California $ 4,018,839 $ 3,981,650 Northern California 5,460,701 5,405,102 Seattle Metro 1,407,033 1,403,678 Other real estate assets 96,500 137,356 Net reportable operating segments - real estate assets 10,983,073 10,927,786 Real estate under development 111,562 386,047 Co-investments 1,177,802 1,018,010 Real estate held for sale — 57,938 Cash and cash equivalents, including restricted cash 58,638 84,041 Marketable securities 191,829 147,768 Notes and other receivables 341,033 195,104 Operating lease right-of-use assets 68,972 72,143 Prepaid expenses and other assets 64,964 47,340 Total assets $ 12,997,873 $ 12,936,177

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company's total minimum lease payment commitments, underground leases, parking leases, and operating leases are disclosed in Note 11, Lease Agreements - Company as Lessee. To the extent that an environmental matter arises or is identified in the future that has other than a remote risk of having a material impact on the financial statements, the Company will disclose the estimated range of possible outcomes associated with it and, if an outcome is probable, accrue an appropriate liability for that matter. The Company will consider whether any such matter results in an impairment of value on the affected property and, if so, the impairment will be recognized. The Company has no way of determining the magnitude of any potential liability to which it may be subject arising out of unknown environmental conditions with respect to the communities currently or formerly owned by the Company. No assurance can be given that: existing environmental assessments conducted with respect to any of these communities have revealed all environmental conditions or potential liabilities associated with such conditions; any prior owner or operator of a property did not create any material environmental condition not known to the Company; or a material unknown environmental condition does not otherwise exist as to any one or more of the communities. The Company has limited insurance coverage for some of the types of environmental conditions and associated liabilities described above. The Company has entered into transactions that may require the Company to pay the tax liabilities of the partners or members in the Operating Partnership or in the DownREIT entities. These transactions are within the Company’s control. Although the Company plans to hold the contributed assets or defer recognition of gain on their sale pursuant to like-kind exchange rules under Section 1031 of the Internal Revenue Code, the Company can provide no assurance that it will be able to do so and if such tax liabilities were incurred they may have a material impact on the Company’s financial position. There continue to be lawsuits against owners and managers of certain of the Company's apartment communities alleging personal injury and property damage caused by the presence of mold in the residential units and common areas of those communities. Some of these lawsuits have resulted in substantial monetary judgments or settlements in the past. The Company has been sued for mold related matters and has settled some, but not all, of such suits. Insurance carriers have reacted to the increase in mold related liability awards by excluding mold related claims from standard general liability policies and pricing mold endorsements at prohibitively high rates. The Company has, however, purchased pollution liability insurance which includes coverage for some mold claims. The Company has also adopted policies intended to promptly address and resolve reports of mold and to minimize any impact mold might have on tenants of its properties. The Company believes its mold policies and proactive response to address reported mold exposures reduces its risk of loss from mold claims. While no assurances can be given that the Company has identified and responded to all mold occurrences, the Company promptly addresses and responds to all known mold reports. Liabilities resulting from such mold related matters are not expected to have a material adverse effect on the Company’s financial condition, results of operations or cash flows. As of December 31, 2021, potential liabilities for mold and other environmental liabilities are not quantifiable and an estimate of possible loss cannot be made. The Company carries comprehensive liability, fire, extended coverage and rental loss insurance for each of the communities. There are, however, certain types of extraordinary losses, such as, for example, losses from terrorism or earthquakes, for which the Company has limited insurance coverage. Substantially all of the communities are located in areas that are subject to earthquake activity. The Company has established a wholly-owned insurance subsidiary, Pacific Western Insurance LLC ("PWI"). Through PWI, the Company is self-insured for earthquake related losses. Additionally, since January 2008, PWI has provided property and casualty insurance coverage for the first $5.0 million of the Company’s property level insurance claims per incident. As of December 31, 2021, PWI has cash and marketable securities of approximately $198.1 million. These assets are consolidated in the Company’s financial statements. Beginning in 2013, the Company has obtained limited third party seismic insurance on selected assets in the Company's co-investments.

Summary of Critical and Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The accounts of the Company, its controlled subsidiaries and the variable interest entities ("VIEs") in which it is the primary beneficiary are consolidated in the accompanying financial statements and prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP"). In the opinion of management, all adjustments necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented have been included and are normal and recurring in nature. All significant inter-company accounts and transactions have been eliminated. Noncontrolling interest includes the 3.4% limited partner interests in the Operating Partnership not held by the Company at both December 31, 2021 and 2020. These percentages include the Operating Partnership’s vested long-term incentive plan units (see Note 14).
Recently Adopted Accounting Pronouncements and Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements In January 2021, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2021-01 "Reference Rate Reform (Topic 848): Scope." The amendments in ASU No. 2021-01 provide optional expedients to the current guidance on contract modifications and hedge accounting from the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. The guidance generally can be applied to applicable contract modifications through December 31, 2022. The Company adopted this new guidance in January 2021 on a prospective basis. This adoption did not have a material impact on the Company's consolidated results of operations or financial position.Recent Accounting PronouncementsIn August 2020, the FASB issued ASU No. 2020-06 “Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity.” The amendments in ASU No. 2020-06 modifies the if-converted method of calculating diluted EPS. For instruments that may be settled in cash or shares, and are not classified as liability, the guidance requires entities to include the effect of potential share settlement in the diluted EPS calculation, if the effect is more dilutive. ASU No. 2020-06 is effective for the Company on January 1, 2022 and will be applied on a prospective basis. The Company does not expect this adoption to have a material impact on its consolidated results of operations or financial position.
Real Estate Rental Properties	Real Estate Rental Properties Significant expenditures, which improve or extend the life of an asset and have a useful life of greater than one year, are capitalized. Operating real estate assets are stated at cost and consist of land and land improvements, buildings and improvements, furniture, fixtures and equipment, and other costs incurred during their development, redevelopment and acquisition. Expenditures for maintenance and repairs are charged to expense as incurred. The depreciable life of various categories of fixed assets is as follows: Computer software and equipment 3 - 5 years Interior apartment home improvements 5 years Furniture, fixtures and equipment 5 - 10 years Land improvements and certain exterior components of real property 10 years Real estate structures 30 years The Company capitalizes all costs incurred with the predevelopment, development or redevelopment of real estate assets or are associated with the construction or expansion of real property. Such capitalized costs include land, land improvements, allocated costs of the Company’s project management staff, construction costs, as well as interest and related loan fees, property taxes and insurance. Capitalization begins for predevelopment, development, and redevelopment projects when activity commences. Capitalization ends when the apartment home is completed and the property is available for a new tenant or if the development activities cease. The Company allocates the purchase price of real estate on a fair value basis to land and building including personal property, and identifiable intangible assets, such as the value of above, below and in-place leases. In making estimates of relative fair values for purposes of allocating purchase price, the Company utilizes a number of sources, including independent land and building appraisals which consider comparable market transactions, its own analysis of recently acquired or developed comparable properties in our portfolio for land comparables and building replacement costs, and other publicly available market data. In calculating the fair value of identified intangible assets of an acquired property, the in-place leases are valued based on in-place rent rates and amortized over the average remaining term of all acquired leases. The values of the above and below market leases are amortized and recorded as either a decrease (in the case of above market leases) or an increase (in the case of below market leases) to rental revenue over the remaining term of the associated leases acquired. The value of acquired in-place leases are amortized to expense over the average remaining term of the leases acquired. The net carrying value of acquired in-place leases is $8.9 million and $4.7 million as of December 31, 2021 and 2020, respectively, and are included in prepaid expenses and other assets on the Company's consolidated balance sheets. The Company periodically assesses the carrying value of its real estate investments for indicators of impairment. The judgments regarding the existence of impairment indicators are based on monitoring investment market conditions and performance compared to budget for operating properties including the net operating income for the most recent 12 month period, monitoring estimated costs for properties under development, the Company's ability to hold and its intent with regard to each asset, and each property's remaining useful life. Whenever events or changes in circumstances indicate that the carrying amount of a property held for investment may not be fully recoverable, the carrying amount is evaluated. If the sum of the expected future cash flows (undiscounted and without interest charges) is less than the carrying amount (including intangible assets) of a property held for investment, then the Company will recognize an impairment loss equal to the excess of the carrying amount over the fair value of the property. Fair value of a property is determined using conventional real estate valuation methods, such as discounted cash flow, the property’s unleveraged yield in comparison to the unleveraged yields and/or sales prices of similar communities that have been recently sold, and other third party information, if available. Communities held for sale are carried at the lower of cost or fair value less estimated costs to sell. As of December 31, 2021, no properties were classified as held for sale. As of December 31, 2020, two properties were classified as held for sale. The Company did not record an impairment charge for the year ended December 31, 2021. The Company recorded an impairment charge of $1.8 million for the year ended December 31, 2020 related to one of the Company's consolidated properties as a result of a change in the Company's intent to hold the property for its remaining useful life. The Company recorded an impairment charge of $7.1 million for the year ended December 31, 2019 on a parcel of land that was part of a consolidated co-investment with Canada Pension Plan Investment Board ("CPPIB" or "CPP"). The impairment charge resulted from the Company's acquisition of CPPIB's 45% interest in the co-investment. The impairment analysis over the parcel’s fair value was determined using internally developed models based on market assumptions. In the normal course of business, the Company will receive purchase offers for its communities, either solicited or unsolicited. For those offers that are accepted, the prospective buyer will usually require a due diligence period before consummation of the transaction. It is not unusual for matters to arise that result in the withdrawal or rejection of the offer during this process. The Company classifies real estate as "held for sale" when the Company has obtained necessary management approvals to sell a property and the sale of the property is expected to be completed within a year. Evaluating solicited or unsolicited offers generally does not cause properties to be classified as held for sale.
Co-investments	Co-investments The Company owns investments in joint ventures in which it has significant influence, but its ownership interest does not meet the criteria for consolidation in accordance with U.S. GAAP. Therefore, the Company accounts for co-investments using the equity method of accounting. Under the equity method of accounting, the investment is carried at the cost of assets contributed, plus the Company’s equity in earnings less distributions received and the Company’s share of losses. The significant accounting policies of the Company’s co-investment entities are consistent with those of the Company in all material respects. Upon the acquisition of a controlling interest of a co-investment, the co-investment entity is consolidated and a gain or loss is recognized upon the remeasurement of co-investments in the consolidated statement of income equal to the amount by which the fair value of the Company's previously owned co-investment interest exceeds its carrying value. A majority of the co-investments, excluding most preferred equity investments, compensate the Company for its asset management services and some of these investments may provide promote income if certain financial return benchmarks are achieved. Asset management
Revenues and Gains on Sale of Real Estate	Revenues and Gains on Sale of Real Estate and Land Revenues from tenants renting or leasing apartment homes are recorded when due from tenants and are recognized monthly as they are earned, which generally approximates a straight-line basis, else, adjustments are made to conform to a straight-line basis. Apartment homes are rented under short-term leases (generally, lease terms of 9 to 12 months). Revenues from tenants leasing commercial space are recorded on a straight-line basis over the life of the respective lease. See Note 4, Revenues, and Note 10, Lease Agreements - Company as Lessor, for additional information regarding such revenues. The Company also generates other property-related revenue associated with the leasing of apartment homes, including storage income, pet rent, and other miscellaneous revenue. Similar to rental income, such revenues are recorded when due from tenants and recognized monthly as they are earned. Apart from rental and other property-related revenue, revenues from contracts with customers are recognized as control of the promised services is passed to the customer. For customer contracts related to management and other fees from affiliates (which includes asset management and property management), the transaction price and amount of revenue to be recognized is determined each quarter based on the management fee calculated and earned for that month or quarter. The contract will contain a description of the service and the fee percentage for management services. Payments from such services are one month or one quarter in arrears of the service performed. The Company recognizes any gains on sales of real estate when it transfers control of a property and when it is probable that the Company will collect substantially all of the related consideration.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted CashHighly liquid investments with original maturities of three months or less when purchased are classified as cash equivalents. Restricted cash balances relate primarily to reserve requirements for capital replacement at certain communities in connection with the Company’s mortgage debt.
Marketable Securities	Marketable SecuritiesThe Company reports its equity securities and available for sale debt securities at fair value, based on quoted market prices (Level 1 for the common stock and investment funds, Level 2 for the unsecured debt and Level 3, as defined by the FASB standard for fair value measurements as discussed later in Note 2). As of December 31, 2021 and 2020, $0.8 million and $2.5 million, respectively, of equity securities presented within common stock and stock funds in the tables below represent investments measured at fair value, using net asset value as a practical expedient, and are not categorized in the fair value hierarchy. Any unrealized gain or loss in debt securities classified as available for sale is recorded as other comprehensive income. There were no other than temporary impairment charges for the years ended December 31, 2021, 2020, and 2019. Unrealized gains and losses in equity securities, realized gains and losses in debt securities, interest income, and amortization of purchase discounts are included in interest and other income on the consolidated statements of income. As of December 31, 2021 and 2020, equity securities and available for sale debt securities consisted primarily of investment-grade unsecured debt, and common stock and stock funds.
Notes Receivable	Notes Receivable Notes receivable relate to real estate financing arrangements including mezzanine and bridge loans. Interest is recognized over the life of the note as interest income. Each note is analyzed to determine if it is impaired. A note is impaired if it is probable that the Company will not collect all contractually due principal and interest. The Company does not accrue interest when a note is considered impaired and an allowance is recorded for any principal and previously accrued interest that are not believed to be collectible. All cash receipts on impaired notes are applied to reduce the principal amount of such notes until the principal has been recovered and, thereafter, are recognized as interest income. As of December 31, 2021 and 2020, no notes were impaired. In the normal course of business, the Company originates and holds two types of loans: mezzanine loans issued to entities that are pursuing apartment development and short-term bridge loans issued to joint ventures with the Company. The Company categorizes development project mezzanine loans into risk categories based on relevant information about the ability of the borrowers to service their debt, such as: current financial information, credit documentation, public information, and previous experience with the borrower. The Company initially analyzes each mezzanine loan individually to classify the credit risk of the loan. On a periodic basis the Company evaluates and performs site visits of the development projects associated with the mezzanine loans to confirm whether they are on budget and whether there are any delays in development that could impact the Company's assessment of credit loss. All bridge loans that the Company issues are, by their nature, short-term and meant only to provide time for the Company’s joint ventures to obtain long-term funding for newly acquired communities. As the Company is a partner in the joint ventures that are borrowing such funds and has performed a detailed review of each community as part of the acquisition process, there is little to no credit risk associated with such loans. As such, the Company does not review credit quality indicators for bridge loans on an ongoing basis.
Capitalization Policy	Capitalization PolicyThe Company capitalizes all direct and certain indirect costs, including interest, employee compensation costs, real estate taxes and insurance, incurred during development and redevelopment activities. Interest is capitalized on real estate assets that require a period of time to get them ready for their intended use. The amount of interest capitalized is based upon the average amount of accumulated development expenditures during the reporting period. Included in capitalized costs are management’s estimates of the direct and incremental personnel costs and indirect project costs associated with the Company's development and redevelopment activities. Indirect project costs consist primarily of personnel costs associated with construction administration and development, including accounting, legal fees, and various corporate and community onsite costs that clearly relate to projects under development. Those costs, inclusive of capitalized interest, as well as capitalized development and redevelopment fees totaled $23.6 million, $31.4 million and $42.1 million for the years ended December 31, 2021, 2020 and 2019, respectively, most of which relates to development projects. The Company capitalizes leasing costs associated with the lease-up of development communities and amortizes the costs over the life of the leases. The amounts capitalized are immaterial for all periods presented.
Fair Value of Financial Instruments	Fair Value of Financial InstrumentsThe Company values its financial instruments based on the fair value hierarchy of valuation techniques described in the FASB’s accounting standard for fair value measurements. Level 1 inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. Level 2 inputs include quoted prices for similar assets and liabilities in active markets and inputs other than quoted prices observable for the asset or liability. Level 3 inputs are unobservable inputs for the asset or liability. The Company uses Level 1 inputs for the fair values of its cash equivalents and its marketable securities except for unsecured bonds and mortgage backed securities. The Company uses Level 2 inputs for its investments in unsecured debt, notes receivable, notes payable, and derivative assets/liabilities. These inputs include interest rates for similar financial instruments. The Company’s valuation methodology for derivatives is described in Note 9. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. Management believes that the carrying amounts of the outstanding balances under its lines of credit, and notes and other receivables approximate fair value as of December 31, 2021 and 2020, because interest rates, yields and other terms for these instruments are consistent with interest rates, yields and other terms currently available for similar instruments. Management has estimated that the fair value of fixed rate debt with a carrying value of $5.7 billion and $5.5 billion at December 31, 2021 and 2020, respectively, to be $6.0 billion at both December 31, 2021 and 2020. Management has estimated the fair value of the Company’s $564.9 million and $775.1 million of variable rate debt at December 31, 2021 and 2020, respectively, to be $561.7 million and $770.1 million at December 31, 2021 and 2020, respectively, based on the terms of existing mortgage notes payable, unsecured debt, and variable rate demand notes compared to those available in the marketplace. Management believes that the carrying amounts of cash and cash equivalents, restricted cash, accounts payable and accrued liabilities, construction payables, other liabilities and dividends payable approximate fair value as of December 31, 2021 and 2020 due to the short-term maturity of these instruments. Marketable securities are carried at fair value as of December 31, 2021 and 2020.
Interest Rate Protection, Swap, and Forward Contracts	Interest Rate Protection, Swap, and Forward Contracts The Company uses interest rate swaps, interest rate caps, and total return swap contracts to manage interest rate risks. The Company’s objective in using derivatives is to add stability to interest expense and to manage its exposure to interest rate movements or other identified risks. To accomplish this objective, the Company uses interest rate swaps as part of its cash flow hedging strategy. The Company records all derivatives on its consolidated balance sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. For derivatives designated for accounting purposes as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in earnings. For derivatives designated for accounting purposes as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (outside of earnings) and subsequently reclassified to earnings when the hedged transaction affects earnings, and the ineffective portion of changes in the fair value of the derivative is recognized directly in earnings. The Company assesses the initial and ongoing effectiveness of each hedging relationship by comparing the changes in fair value or cash flows of the derivative hedging instrument with the changes in fair value or cash flows of the designated hedged item or transaction. For derivatives not designated for accounting purposes as cash flow hedges, changes in fair value are recognized in earnings. All of the Company’s interest rate swaps are considered cash flow hedges.
Income Taxes	Income TaxesGenerally in any year in which Essex qualifies as a real estate investment trust ("REIT") under the Internal Revenue Code (the "IRC"), it is not subject to federal income tax on that portion of its income that it distributes to stockholders. No provision for federal income taxes, other than the taxable REIT subsidiaries discussed below, has been made in the accompanying consolidated financial statements for each of the years in the three-year period ended December 31, 2021 as Essex has elected to be and believes it qualifies under the IRC as a REIT and has made distributions during the periods in amounts to preclude Essex from paying federal income tax. In order to maintain compliance with REIT tax rules, the Company utilizes taxable REIT subsidiaries for various revenue generating or investment activities. The taxable REIT subsidiaries are consolidated by the Company. In general, the activities and tax related provisions, assets and liabilities are not material. As a partnership, the Operating Partnership is not subject to federal or state income taxes, except that in order to maintain Essex's compliance with REIT tax rules that are applicable to Essex, the Operating Partnership utilizes taxable REIT subsidiaries for various revenue generating or investment activities. The taxable REIT subsidiaries are consolidated by the Operating Partnership.
Equity-based Compensation	Equity-based CompensationThe cost of share- and unit-based compensation awards is measured at the grant date based on the estimated fair value of the awards. The estimated fair value of stock options and restricted stock granted by the Company are being amortized over the vesting period. The estimated grant date fair values of the long-term incentive plan units (discussed in Note 14) are being amortized over the expected service periods.
Changes in Accumulated Other Comprehensive Loss, by Component	Amounts reclassified from accumulated other comprehensive loss in connection with derivatives are recorded in interest expense on the consolidated statements of income. Realized gains and losses on available for sale debt securities are included in interest and other income on the consolidated statements of income.
Accounting Estimates	Accounting EstimatesThe preparation of consolidated financial statements, in accordance with U.S. GAAP, requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosures of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to acquiring, developing and assessing the carrying values of its real estate portfolio, its investments in and advances to joint ventures and affiliates, and its notes receivable. The Company bases its estimates on historical experience, current market conditions, and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may vary from those estimates and those estimates could be different under different assumptions or conditions.
Variable Interest Entities	Variable Interest EntitiesIn accordance with accounting standards for consolidation of VIEs, the Company consolidated the Operating Partnership, 18 DownREIT entities (comprising nine communities), and six co-investments as of December 31, 2021. The Company consolidated the Operating Partnership, 17 DownREIT entities (comprising nine communities), and five co-investments as of December 31, 2020. The Company consolidates these entities because it is deemed the primary beneficiary. The Company has no assets or liabilities other than its investment in the Operating Partnership. The consolidated total assets and liabilities related to the above consolidated co-investments and DownREIT entities, net of intercompany eliminations, were approximately $909.3 million and $320.1 million, respectively, as of December 31, 2021, and $898.5 million and $326.8 million, respectively, as of December 31, 2020. Noncontrolling interests in these entities were $122.4 million and $120.8 million as of December 31, 2021 and 2020, respectively. The Company's financial risk in each VIE is limited to its equity investment in the VIE. The DownREIT VIEs collectively own nine apartment communities in which the Company is the general partner or manager of the DownREIT entity, the Operating Partnership is a special limited partner or member, and the other limited partners or members were granted rights of redemption for their interests. Such limited partners or members can request to be redeemed and the Company, subject to certain restrictions, can elect to redeem their rights for cash or by issuing shares of its common stock on a one share per unit basis. Conversion values will be based on the market value of the Company's common stock at the time of redemption multiplied by the number of units stipulated under various arrangements, as noted above. The other limited partners or members receive distributions based on the Company's current dividend rate times the number of units held. Total DownREIT units outstanding were 978,854 and 1,017,460 as of December 31, 2021 and 2020, respectively, and the redemption value of the units, based on the closing price of the Company’s common stock totaled approximately $344.8 million and $241.6 million, as of December 31, 2021 and 2020, respectively. The carrying value of redeemable noncontrolling interest in the accompanying balance sheets was $34.7 million and $32.2 million as of December 31, 2021 and 2020, respectively. Of these amounts, $7.7 million and $11.9 million as of December 31, 2021 and 2020, respectively, represent units of limited partners' or members' interests in DownREIT VIEs as to which it is outside of the Company’s control to redeem the DownREIT units with Company common stock and may potentially be redeemed for cash, and are presented at either their redemption value or historical cost, depending on the limited partner's or members' right to redeem their units as of the balance sheet date. The carrying value of DownREIT units as to which it is within the control of the Company to redeem the units with its common stock was $97.4 million as of both December 31, 2021 and 2020, and is classified within noncontrolling interests in the accompanying consolidated balance sheets. Interest holders in VIEs consolidated by the Company are allocated a priority of net income equal to the cash payments made to those interest holders or distributions from cash flow. The remaining results of operations are generally allocated to the Company.
