Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION	DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION Description of Business: Cousins Properties Incorporated (“Cousins”), a Georgia corporation, is a self-administered and self-managed real estate investment trust (“REIT”). Cousins conducts substantially all of its business through Cousins Properties, LP ("CPLP"). Cousins owns in excess of 99% of CPLP and consolidates CPLP. CPLP wholly owns Cousins TRS Services LLC ("CTRS") a taxable entity which owns and manages its own real estate portfolio and performs certain real estate related services for other parties. Cousins, CPLP, CTRS, and their subsidiaries (collectively, the “Company”) develop, acquire, lease, manage, and own primarily Class A office properties and opportunistic mixed-use developments in the Sun Belt markets of the United States with a focus on Atlanta, Austin, Charlotte, Phoenix, Tampa, Dallas, and Nashville. Cousins has elected to be taxed as a REIT and intends to, among other things, distribute at least 100% of its net taxable income to stockholders, thereby eliminating any liability for federal income taxes under current law. Therefore, the results included herein do not include a federal income tax provision for Cousins. As of December 31, 2021, the Company’s portfolio of real estate assets consisted of interests in 18.3 million square feet of office space and 620,000 square feet of other space. Basis of Presentation: The consolidated financial statements include the accounts of the Company and its consolidated partnerships and wholly-owned subsidiaries. Intercompany transactions and balances have been eliminated in consolidation. The Company presents its financial statements in accordance with accounting principles generally accepted in the United States (“GAAP”) as outlined in the Financial Accounting Standard Board’s Accounting Standards Codification (the “Codification” or “ASC”). The Codification is the single source of authoritative accounting principles applied by nongovernmental entities in the preparation of financial statements in conformity with GAAP. For the three years ended December 31, 2021, there were no items of other comprehensive income. Therefore, the Company did not present comprehensive income. The Company evaluates all partnerships, joint ventures, and other arrangements with variable interests to determine if the entity or arrangement qualifies as a variable interest entity (“VIE”), as defined in the Codification. If the entity or arrangement qualifies as a VIE and the Company is determined to be the primary beneficiary, the Company is required to consolidate the assets, liabilities, and results of operations of the VIE. In 2020, the Company transferred the right to purchase a building to a special purpose entity to facilitate a potential reverse Section 1031 exchange under the Internal Revenue Code of 1986, as amended (the "Code"), and the special purpose entity purchased the building and retained the assets acquired therefrom. To realize the tax deferral available under Section 1031 exchange, the Company must identify the like-kind property to be disposed of within 45 days of the acquisition date and complete the transfer of the title to the to-be-exchanged building within 180 days of the acquisition date. We concluded that Cousins had a controlling financial interest and was, therefore, the primary beneficiary of the venture. The Company consolidated this VIE entity. As of December 31, 2020, this VIE had total assets of $210.2 million and total liabilities of $209.7 million. The liabilities of this VIE eliminate in our consolidated balance sheet. As of December 31, 2021, the Company did not have any partnerships, joint ventures, or other arrangements with variable interests that qualified as a VIE.

Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Real Estate Assets Cost Capitalization: Costs related to planning, developing, leasing, and constructing a property, including costs of development personnel working directly on projects under development, are capitalized. In addition, the Company capitalizes interest to qualifying assets under development based on average accumulated expenditures outstanding during the period. In capitalizing interest to qualifying assets, the Company first uses the interest incurred on specific project debt, if any, and next uses the Company’s weighted average interest rate for non-project specific debt. The Company also capitalizes interest to investments accounted for under the equity method when the investee has property under development with a carrying value in excess of the investee’s borrowings. To the extent debt exists within an unconsolidated joint venture during the construction period, the venture capitalizes interest on that venture-specific debt. The Company capitalizes interest, real estate taxes, and certain operating expenses on the unoccupied portion of recently completed development properties until the date a project is substantially complete and held for occupancy, which is the earlier of (1) the date on which the project achieves 90% economic occupancy or (2) one year from cessation of major construction activity. Impairment: We review our real estate assets on a property-by-property basis for impairment. This review includes our operating properties, properties under development, and land holdings. The first step in this process is to determine whether an asset is considered to be held and used or held for sale, in accordance with accounting guidance. In order to be considered a real estate asset held for sale, we must, among other things, have the authority to commit to a plan to sell the asset in its current condition, have commenced the plan to sell the asset, and have determined that it is probable that the asset will sell within one year. If we determine that an asset is held for sale, we record an impairment loss if the fair value less costs to sell is less than the carrying amount. All real estate assets not meeting the held for sale criteria are considered to be held and used. In the impairment analysis for assets held and used, we must determine whether there are indicators of impairment. For operating properties, these indicators could include a decline in a property’s leasing percentage, a current period operating loss or negative cash flows combined with a history of losses at the property, a decline in lease rates for that property or others in the property’s market, a significant change in the market value of the property, or an adverse change in the financial condition of significant tenants. For projects under development, indicators could include material budget overruns, significant delays in construction, occupancy, or stabilization schedule, regulatory changes or economic trends that have a significant impact on the market, or an adverse change in the financial condition of significant future tenants. For land holdings, indicators could include an overall decline in the market value of land in the region, a decline in development activity for the intended use of the land, or other adverse economic and market conditions. Acquisition of Real Estate Assets: The Company evaluates all real estate acquisitions to determine if the transactions qualify as an acquisition of assets or of a business. If the Company determines that substantially all of the fair value is concentrated in a single identifiable asset or group of similar assets, the Company will account for the acquisition as an acquisition of assets and not a business. If the Company determines that there is no single or group of assets that make up substantially all of the fair value of assets acquired, the Company must determine whether the acquired set of assets includes an input and substantial processes which create an output. Based on the facts of the transactions and guidance in ASC 805, if the Company determines that an input and substantial processes that create an output are present, the Company will account for the acquisition as an acquisition of a business. For acquisitions that are accounted for as an acquisition of an asset, the Company records the acquired tangible and intangible assets and assumed liabilities based on each asset and liability's relative fair value at the acquisition date to the total purchase price plus capitalized acquisition costs. For acquisitions that are accounted for as an acquisition of a business, the Company records the acquired tangible and intangible assets and assumed liabilities at fair value at the acquisition date. The acquired assets and assumed liabilities for an operating property acquisition generally include but are not limited to: land, buildings and improvements, and identified tangible and intangible assets and liabilities associated with in-place leases, including leasing costs, value of above-market and below-market tenant leases, value of above-market and below-market ground leases, acquired in-place lease values, and tenant relationships, if any. The fair value of land is derived from comparable sales of land within the same submarket and/or region. The fair value of buildings and improvements, tenant improvements, and leasing costs are based upon current market replacement costs and other relevant market rate information. The fair value of the above-market or below-market component of an acquired lease is based upon the present value (calculated using a market discount rate) of the difference between (1) the contractual rents to be paid pursuant to the lease over its remaining term and (2) management’s estimate of the rents that would be paid using fair market rental rates and rent escalations at the date of acquisition over the remaining term of the lease. The amounts recorded for above-market and below-market ground leases are included in intangible liabilities and intangible assets, respectively, and are amortized on a straight-line basis into rental property revenues over the remaining terms of the applicable leases. The fair value of acquired in-place leases is derived based on management’s assessment of lost revenue and costs incurred for the period required to lease the “assumed vacant” property to the occupancy level when purchased. The amount recorded for acquired in-place leases is included in intangible assets and amortized as an increase to depreciation and amortization expense over the remaining term of the applicable leases. Depreciation and Amortization: Real estate assets are stated at depreciated cost less impairment, if any. Buildings are depreciated over their estimated useful lives, which range generally from 30 to 42 years. The life of a particular building depends upon a number of factors including whether the building was developed or acquired and the condition of the building upon acquisition. Furniture, fixtures, and equipment are depreciated over their estimated useful lives of three bankruptcy, vacates its premises, or defaults in another manner on its lease. Deferred expenses are amortized over the period of estimated benefit. The Company uses the straight-line method for all depreciation and amortization. Investment in Joint Ventures For joint ventures that the Company does not control, but over which it exercises significant influence, the Company uses the equity method of accounting. The Company's judgment with regard to its level of influence or control of an entity involves consideration of various factors including the form of its ownership interest; its representation in the entity's governance; its ability to participate in policy-making decisions; and the rights of other investors to participate in the decision-making process, to replace the Company as manager, and/or to liquidate the venture. These ventures are recorded at cost and adjusted for equity in earnings (losses) and cash contributions and distributions. Any difference between the carrying amount of these investments on the Company’s consolidated balance sheet and the underlying equity in net assets on the joint venture’s balance sheet is adjusted as the related underlying assets are depreciated, amortized, or sold. The Company generally allocates income and loss from an unconsolidated joint venture based on the venture's distribution priorities, which may be different from its stated ownership percentage. The Company evaluates the recoverability of its investment in unconsolidated joint ventures in accordance with accounting standards for equity investments by first reviewing each investment for any indicators of impairment. If indicators are present, the Company estimates the fair value of the investment. If the carrying value of the investment is greater than the estimated fair value, management makes an assessment of whether the impairment is “temporary” or “other-than-temporary.” In making this assessment, management considers the following: (1) the length of time and the extent to which fair value has been less than cost, (2) the financial condition and near-term prospects of the entity, and (3) the Company’s intent and ability to retain its interest long enough for a recovery in market value. If management concludes that the impairment is "other than temporary," the Company reduces the investment to its estimated fair value. Noncontrolling Interest The Company consolidates CPLP and certain joint ventures in which it owns a controlling interest. In cases where the entity’s documents do not contain a required redemption clause, the Company records the partner’s share of the entity in the equity section of the balance sheets in nonredeemable noncontrolling interests. In cases where the entity’s documents contain a provision requiring the Company to purchase the partner’s share of the venture at a certain value upon demand or at a future date, if any, the Company records the partner’s share of the entity in redeemable noncontrolling interests on the balance sheets. The outside partners' interests in CPLP are redeemable upon demand into cash or shares of common stock of the Company at the Company's sole discretion. Therefore, noncontrolling interests associated with CPLP are considered nonredeemable noncontrolling interests. The noncontrolling partners' share of all consolidated entities' income is reflected in net income attributable to noncontrolling interest on the statements of operations. Revenue Recognition Rental Property Revenues: The Company recognizes contractual revenues from leases on a straight-line basis over the term of the respective lease. If we determine the improvements are our assets, we capitalize the cost of the improvements and recognize depreciation expense associated with such improvements over the shorter of the estimated useful life or the term of the lease. If the improvements are tenant assets, we defer the cost of improvements funded by us as a lease incentive asset and amortize it as a reduction of rental revenue over the term of the lease. Our determination of whether improvements are our assets or tenant assets also affects when we commence revenue recognition in connection with a lease. The Company records deferred revenue for the portion of company owned tenant improvements funded or reimbursed by tenants and amortizes this amount on a straight-line basis into rental income over the term of the related lease. As of December 31, 2021 and 2020, the Company had unamortized deferred income related to tenant funded tenant improvements of $30.2 million and $31.6 million, respectively, included in deferred income on the consolidated balance sheets. Certain leases also provide for percentage rents based upon the level of sales achieved by the lessee. Percentage rents are recognized once the specified sales target is achieved. In addition, leases typically provide for reimbursement of the tenants' share of real estate taxes, insurance, and other operating expenses to the Company. Operating expense reimbursements are recognized as the related expenses are incurred. During 2021, 2020, and 2019, the Company recognized $155.5 million, $142.5 million, and $122.4 million, respectively, in revenues from tenants related to operating expense reimbursements. The Company makes valuation adjustments to all tenant-related accounts receivable based upon its estimate of the likelihood of collectibility of amounts due from the tenant. The amount of any valuation adjustment is based on the tenant’s credit and business risk, history of payment, and other factors considered by management. In limited circumstances to date, the Company has entered into lease amendments with certain tenants, a majority of which are small retail operators who have experienced disruptions in their business as a result of the COVID-19 pandemic. Some of these agreements forgive rents and extend the lease term for the equivalent number of months at the end of the original lease and others provide for forgiveness without extension. Rent forgiveness, with or without extensions, is accounted for as lease modifications, and the Company recognizes the effects over time through straight-line rent over the lease term. Other agreements provide for payment deferrals without extensions. The Company accounts for these deferral agreements as lease modifications and has included these deferred payments in deferred rents receivable on the accompanying consolidated balance sheets. Fee Income: The Company recognizes development, management, and leasing fees as it satisfies the related performance obligations under the respective contracts. The Company recognizes development and leasing fees received from investments in unconsolidated joint ventures and related salaries and other direct costs incurred by the Company as income and expense based on the percentage of the joint venture which the Company does not own. Correspondingly, the Company adjusts its investment in unconsolidated joint ventures when fees are paid to the Company by a joint venture in which the Company has an ownership interest. Gain on Investment Property Transactions: The Company recognizes a gain on the sale of investment property at the time the buyer obtains control of the investment property. If the Company maintains any continuing involvement with the investment property, that continuing involvement is considered to be one or more additional performance obligations and additional gains or losses will be recognized as these performance obligations are satisfied. When the Company gains control of a previously unconsolidated investment accounted for under the equity method of accounting, it records a gain for the difference between the carrying value of its equity method investment and the fair value of that investment on the date control is gained. Income Taxes The Company has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify as a REIT, the Company must distribute annually at least 90% of its adjusted taxable income, as defined in the Code, to its stockholders and satisfy certain other organizational and operating requirements. It is management’s current intention to adhere to these requirements and maintain the Company's REIT status. As a REIT, the Company generally will not be subject to federal income tax at the corporate level on the taxable income it distributes to its stockholders. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal income taxes at regular corporate rates and may not be able to qualify as a REIT for four subsequent taxable years. The Company may be subject to certain state and local taxes on its income and property, and to federal income taxes on its undistributed taxable income. CTRS is a C-Corporation for federal income tax purposes and uses the liability method for accounting for income taxes. Tax return positions are recognized in the financial statements when they are “more-likely-than-not” to be sustained upon examination by the taxing authority. Deferred income tax assets and liabilities result from temporary differences. Temporary differences are differences between the tax bases of assets and liabilities and their reported amounts in the financial statements that will result in taxable or deductible amounts in future periods. A valuation allowance may be placed on deferred income tax assets, if it is determined that it is more likely than not that a deferred tax asset may not be realized. Stock Compensation The Company accounts for stock-based employee compensation using the fair value based method of accounting. We classify share-based payment awards granted in exchange for employee services as either equity awards or liability awards. Equity-classified awards are measured based on the fair value on the date of grant. Awards that are to be settled in cash are classified as liability awards. The value of all of the Company's share-based awards is recognized over the period during which an employee is required to provide services in exchange for the award - the requisite service period (usually the vesting period). No compensation costs are recognized for awards for which employees do not complete the requisite service period. Earnings per Share Net income per share-basic is calculated as net income available to common stockholders divided by the weighted average number of common shares outstanding during the period, including nonvested restricted stock which has nonforfeitable dividend rights. Net income per share-diluted is calculated as net income available to common stockholders plus noncontrolling interests in CPLP divided by the diluted weighted average number of common shares outstanding during the period. Diluted weighted average number of common shares uses the same weighted average share number as in the basic calculation and adds the potential dilution that would occur if i) the outside units in CPLP were converted into the Company's common stock, ii) any stock options were exercised, iii) any forward sales contracts of our common stock were settled, and iv) equity-based restricted stock units ("RSUs") as well as shares to be issued under the Employee Stock Purchase Plan (“ESPP”) were vested and settled resulting in additional common shares outstanding, all calculated using the treasury stock method, as applicable. Stock options are dilutive when the average market price of the Company’s stock during the period exceeds the option exercise price. RSUs are dilutive if the shares to be granted (assuming the end of the reporting period is the end of the measurement of any required market and performance achievement) exceed the shares assumed to be repurchased under the treasury stock method (using related unamortized compensation costs as proceeds). Shares to be issued under the ESPP are dilutive if the estimated shares to be purchased under the plan based on current enrollment elections exceed the shares assumed to be repurchased under the treasury stock method (using both employee ESPP contributions and related unamortized compensation costs as proceeds). On January 1, 2021, the Company early adopted ASU 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)" ("ASU 2020-06"). The adoption of ASU 2020-06 could potentially impact the denominator in our diluted earnings per share calculation in the future. For the year ended December 31, 2021, it did not impact the denominator. Cash and Cash Equivalents Cash and cash equivalents include unrestricted cash and highly-liquid money market instruments. Highly-liquid money market instruments include securities and repurchase agreements with original maturities of three months or less, money market mutual funds, and United States Treasury Bills with maturities of 30 days or less. Restricted Cash Restricted cash primarily includes escrow accounts held by lenders for reserves or to pay real estate taxes. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

TRANSACTIONS WITH TIER REIT, INC.	TRANSACTIONS WITH TIER REIT, INC. On June 14, 2019, pursuant to the Agreement and Plan of Merger dated March 25, 2019 (the “Merger Agreement”), by and among the Company and TIER REIT, Inc. (“TIER”), TIER merged with and into a subsidiary of the Company (the “Merger”) with this subsidiary continuing as the surviving corporation of the Merger. The Merger has enhanced the Company's position in its existing markets of Austin and Charlotte, provided a strategic entry into Dallas, and rebalanced the Company's portfolio across its markets. In accordance with the terms and conditions of the Merger Agreement, each share of TIER common stock issued and outstanding immediately prior to the Merger, was converted into 2.98 newly issued, pre-reverse split shares of the Company’s common stock with fractional shares being settled in cash. In the Merger, former TIER common stockholders received approximately 166 million pre-reverse split shares of common stock of the Company. As discussed in note 1 to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020, immediately following the Merger, the Company completed a 1-for-4 reverse stock split. The Merger has been accounted for as a business combination with the Company as the accounting acquirer, which requires, among other things, that the assets acquired and liabilities assumed be recognized at their acquisition date fair value. The total value of the transaction is based on the closing stock price of the Company's common stock on June 13, 2019, the day immediately prior to the closing of the Merger. Based on the shares issued in the transaction, the total fair value of the assets acquired net of liabilities assumed in the Merger was $1.6 billion. During the years ended December 31, 2020 and December 31, 2019, the Company incurred expenses related to the Merger of $428,000 and $52.9 million, respectively. During 2021, there were no expenses incurred related to the Merger. Management engaged a third party valuation specialist to assist with valuing the real estate assets acquired and liabilities assumed in the Merger. The third party used cash flow analyses, as well as a market approach, an income approach, and a cost approach to determine the fair value of real estate assets acquired. The purchase price was allocated as follows (in thousands): Real estate assets $ 2,202,073 Real estate assets held for sale 20,835 Cash and cash equivalents 84,042 Restricted cash 1,947 Notes and other receivables 8,278 Investment in unconsolidated joint ventures 331 Intangible assets 141,184 Other assets 10,040 2,468,730 Notes payable 747,549 Accounts payable and accrued expenses 53,321 Deferred income 8,388 Intangible liabilities 47,988 Other liabilities 7,793 Nonredeemable noncontrolling interests 5,329 870,368 Total purchase price $ 1,598,362 The following unaudited supplemental pro forma information is based upon the Company's historical consolidated statements of operations, adjusted as if the Merger had occurred on January 1, 2018. The supplemental pro forma information is not necessarily indicative of future results, or of actual results, that would have been achieved had the Merger been consummated at the beginning of the period. Year ended (unaudited, in thousands) Revenues $ 750,080 Net income 232,136 Net income available to common stockholders 229,503 2019 supplemental pro forma earnings were adjusted to exclude the $52.9 million of transaction costs incurred in the year ended December 31, 2019. On March 1, 2019, the Company entered into a series of agreements and executed related transactions with Norfolk Southern Railway Company (“NS”) as follows: • Sold land to NS for $52.5 million. • Executed a Development Agreement with NS whereby the Company will receive fees totaling $5 million in consideration for development services for NS’s corporate headquarters that is being constructed on the land sold to NS. • Executed a Consulting Agreement with NS whereby the Company will receive fees totaling $32 million in consideration for consulting services for NS’s corporate headquarters. The Development Agreement and Consulting Agreement are collectively referred to below as the “Fee Agreements.” • Purchased a building from NS (“Promenade Central fka 1200 Peachtree”) for $82 million subject to a three-year market rate lease with NS that covers the entire building. The Company sold the land to NS for $5.0 million above its carrying amount, which included $37.0 million of land purchased in 2018, $6.5 million of land purchased in 2019, and $4.0 million of site preparation work. The Company purchased Promenade Central fka 1200 Peachtree from NS for an amount it determined to be $10.3 million below the building’s fair value. The Company determined that all contracts and transactions associated with NS should be combined for accounting purposes, and the amounts exchanged under the combined contracts should be allocated to the various components of the overall transaction at fair value or market value as discussed below. The Company determined that the purchase of Promenade Central fka 1200 Peachtree should be recorded at fair value of $92.3 million. The Company determined that the lease with NS at the Promenade Central fka 1200 Peachtree building was at market value under ASC 842. The land sale was accounted for under ASC 610-20, and no gain or loss was recorded on the derecognition of this non-financial asset as the fair value was determined to equal the carrying amount. Consideration related to various services provided to NS, and accounted for under ASC 606, was determined to be $52.3 million and represents the negotiated market value for the services agreed to by the Company and NS in the contracts. This amount included non-cash consideration of the $10.3 million discount on the purchase of Promenade Central fka 1200 Peachtree as well as cash consideration of $5.0 million from the land sale contract (difference between fair value and contract amount), $5.0 million from the Development Agreement, and $32.0 million from the Consulting Agreement. Since all of the agreements and contracts above were executed for the purpose of delivering and constructing a corporate headquarters for NS and all of the services and deliverables are highly interdependent, the Company determined that the services represent a single performance obligation under ASC 606. The Company determined that control of the services to be provided is being transferred over time and, thus, the Company must recognize the $52.3 million contract price in revenue as it satisfies the performance obligation. The Company determined that the inputs method of measuring progress of satisfying the performance obligation was the most appropriate method of recognizing revenue for the services component. Therefore, the Company began recognizing revenue on March 1, 2019, based upon the time spent by the Company’s employees in providing these services as compared to the total estimated time required to satisfy the performance obligation. During the years ended December 31, 2021, 2020, and 2019, the Company recognized $11.9 million, $14.9 million, and $21.4 million, respectively, in fee income in the consolidated statements of operations related to the services provided to NS. As of December 31, 2021 and December 31, 2020, the Company had deferred income related to NS included in the consolidated balance sheet of $1.8 million and $5.7 million, respectively.

The Company recorded a gain of $90.2 million from the 2021 sales. The Company recorded a gain of $90.3 million from the 2020 sales, which is net of $459,000 of state income tax. The Company did not sell any operating properties in 2019. In July 2021, the Company sold 0.7 acres of land in Phoenix, adjacent to our 100 Mill development, to a hotel developer for $6.4 million. Net proceeds approximated our book value. During February 2019, the Company sold air rights that cover eight acres in Downtown Atlanta for a gross price of $13.3 million and recorded a gain of $13.1 million. Held for Sale Building The Company's Burnett Plaza property in Fort Worth was classified as held for sale as of December 31, 2020 as the result of the Company accepting an offer for the sale of the property in the fourth quarter of 2020. The major classes of assets and liabilities of this property held for sale were as follows (in thousands): December 31, 2020 Real estate asset and other assets held for sale Operating property, net of accumulated depreciation of $8,123 $ 106,864 Notes and accounts receivable 439 Deferred rents receivable 2,480 Intangible assets, net of accumulated amortization of $6,065 15,830 Other assets 133 Total real estate asset and other assets held for sale $ 125,746 Liabilities of real estate asset held for sale Accounts payable and accrued expenses $ 7,399 Deferred income 44 Intangible liabilities, net of accumulated amortization of $1,205 3,014 Other liabilities 2,149 Total liabilities of real estate asset held for sale $ 12,606 Impairment The Company tests for impairment whenever changes in circumstances indicate a building’s carrying value may not be recoverable. The test is conducted using undiscounted cash flows for the shorter of the building’s estimated hold period or its remaining useful life. When testing for recoverability of buildings held for investment, projected cash flows are used over its expected hold period. If the expected hold period includes some likelihood of shorter-term hold period from a potential sale, the probability of a sale is layered into the analysis. If any building's held for investment analysis were to fail the impairment test, its book value would be written down to its then current estimated fair value, before any selling expense, and that building would continue to depreciate over its remaining useful life. None of the Company’s buildings were impaired during any periods presented while under the held for investments classification. During the fourth quarter of 2020, the Company decided to accept an offer, with conditions, on Burnett Plaza. Based on the status of this offer as of December 31, 2020, the Company concluded the sale was probable within one year and, therefore, transferred the assets and liabilities of the building to held for sale. Because the carrying value of the building exceeded the expected net sale proceeds (including selling costs), the Company recorded a $14.8 million impairment charge in the accompanying statement of operations. The net proceeds were based on the third-party offer to purchase (a Level 2 input under authoritative guidance for fair value measurements). The Company may record additional impairment charges if operating results of individual buildings are materially different from our forecasts, the economy and the office industry weakens, or we shorten our contemplated holding period for additional buildings.

Leases [Abstract]
Leases	LEASES At December 31, 2021, the Company had three properties subject to operating ground leases with a weighted average remaining term of 79 years and one finance ground lease with a remaining term of four years. At December 31, 2021, the Company had right-of-use assets from operating ground leases of $46.1 million included in operating properties or land land other liabilities Rental payments on these ground leases are adjusted periodically based on either the Consumer Price Index, changes in developed square feet on the underlying leased asset, or on a pre-determined schedule. The monthly payments on a pre-determined schedule are recognized on a straight-line basis over the terms of the respective leases while payments resulting from changes in the Consumer Price Index or future development are reflected in the statement of operations at the time of the change. For the years ended December 31, 2021, 2020, and 2019, the Company recognized operating ground lease expense of $4.1 million, $4.3 million, and $3.9 million, respectively. For the year ended December 31, 2021 the Company had no variable lease expenses related to ground lease expense, and recognized interest expense related to finance ground leases of $162,000 . For the year ended December 31, 2021, the Company paid $2.3 million in cash related to operating ground leases and made $162,000 in cash payments related to financing ground leases.

At December 31, 2021, the New Term Loan's spread over LIBOR was 1.05%. The Company is in compliance with all covenants of the New Term Loan. Prior to June 28, 2021, the Company had a $250 million unsecured term loan (the "Old Term Loan") that was scheduled to mature on December 2, 2021. The Old Term Loan had financial covenants consistent with those of the Credit Facility. The interest rate applicable to the Old Term Loan varied according to the Company's leverage ratio and could have, at the election of the Company, been determined based on either (1) the current LIBOR plus a spread of between 1.20% and 1.70%, based on leverage or (2) the greater of Bank of America's prime rate, the federal funds rate plus 0.50%, or the one-month LIBOR plus 1.00%, plus a spread of between 0.00% and 0.75%, based on leverage.

The senior notes also contain customary representations and warranties and affirmative and negative covenants, as well as customary events of default. The Company is in compliance with all covenants of the unsecured senior notes. Secured Mortgage Notes In June 2021, the Company executed a collateral substitution for the mortgage previously secured by the Company's 816 Congress property in Austin. The mortgage is now secured by the Company's Domain 10 property in Austin. All other terms of the note were unchanged. In February 2020, the Company prepaid in full the $23.0 million Meridian Mark Plaza mortgage note, without penalty. As of December 31, 2021, the Company had $661.5 million outstanding on seven non-recourse mortgage notes. All interest rates on the secured mortgage notes are fixed. Assets with depreciated carrying values of $1.1 billion were pledged as security on these mortgage notes payable. Other Debt Information At December 31, 2021 and 2020, the estimated fair value of the Company’s notes payable was $2.3 billion, c alculated by discounting the debt's remaining contractual cash flows at estimated rates at which similar loans could have been obtained at December 31, 2021 and 2020. The estimate of the current market rate, which is the most significant input in the discounted cash flow calculation, is intended to replicate debt of similar maturity and loan-to-value relationship. These fair value calculations are considered to be Level 2 under the guidelines as set forth in ASC 820 as the Company utilizes market rates for similar type loans from third party brokers. For the years ended December 31, 2021, 2020, and 2019, interest was recorded as follows (in thousands): 2021 2020 2019 Total interest incurred $ 73,284 $ 74,929 $ 65,182 Interest capitalized (6,257) (14,324) (11,219) Total interest expense $ 67,027 $ 60,605 $ 53,963 Debt Maturities Future principal payments due (including scheduled amortization payments and payments due upon maturity) on the Company's notes payable at December 31, 2021 are as follows (in thousands): 2022 $ 102,401 2023 481,655 2024 429,087 2025 256,755 2026 220,127 Thereafter 750,000 $ 2,240,025

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Commitments The Company had outstanding performance bonds totaling $496,000 at December 31, 2021. As a lessor, the Company had a total of $255.6 million in future obligations under leases to fund tenant improvements and other future construction obligations at December 31, 2021. Litigation The Company is subject to various legal proceedings, claims and administrative proceedings arising in the ordinary course of business, some of which are expected to be covered by liability insurance. Management makes assumptions and estimates concerning the likelihood and amount of any potential loss relating to these matters using the latest information available. The Company records a liability for litigation if an unfavorable outcome is probable and the amount of loss or range of loss can be reasonably estimated. If an unfavorable outcome is probable and a reasonable estimate of the loss is a range, the Company accrues the best estimate within the range. If no amount within the range is a better estimate than any other amount, the Company accrues the minimum amount within the range. If an unfavorable outcome is probable but the amount of the loss cannot be reasonably estimated, the Company discloses the nature of the litigation and indicates that an estimate of the loss or range of loss cannot be made. If an unfavorable outcome is reasonably possible and the estimated loss is material, the Company discloses the nature and estimate of the possible loss of the litigation. The Company does not disclose information with respect to litigation where an unfavorable outcome is considered to be remote or where the estimated loss would not be material. Based on current expectations, such matters, both individually and in the aggregate, are not expected to have a material adverse effect on the liquidity, results of operations, business or financial condition of the Company. Contingencies Recent events related to the COVID-19 pandemic and the actions taken to contain it have created substantial uncertainty for all businesses, including the Company. The Company’s consolidated financial statements as of and for the year ended December 31, 2021 have been prepared in light of these circumstances without any impairments on held for use long-lived investments or significant valuation adjustments to amounts due from tenants. However, circumstances related to the COVID-19 pandemic may result in recording impairments or material valuation adjustments to amounts due from tenants in future periods.

Stockholders' Equity	Dec. 31, 2021
Equity [Abstract]
STOCKHOLDERS' EQUITY	STOCKHOLDERS' EQUITY In the third quarter of 2021, the Company entered into an Equity Distribution Agreement with six financial institutions known as an at-the-market stock offering program ("ATM program"), under which the Company may offer and sell shares of its common stock from time to time in "at-the-market" offerings with an aggregate gross sales price of up to $500 million. In connection with the ATM program, the Company may, at its discretion, enter into forward equity sale agreements. The use of a forward equity 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 receiving the proceeds from the sale of shares until a later date, allowing the Company to better align such funding with its capital needs. Sales of shares of the Company's stock through its banking relationships, if any, are made in amounts and at times to be determined by the Company from time to time, but the Company has no obligation to sell any of the shares in the offering and may suspend sales in connection with the offering at any time. Sales of the Company's common stock under forward equity sale agreements, if undertaken, meet the derivatives and hedging guidance scope exception as the contracts are related to the Company's own stock. To date, the Company has sold 2.6 million shares under forward equity sale agreements, all of which were outstanding as of December 31, 2021, and are currently expected to settle by September 30, 2022 for proceeds of $104.0 million, net of $1.1 million of compensation to be paid with respect to such sales. The Company has not received proceeds related to these sales or issued any shares under the ATM program. To the extent unsettled shares sold under forward equity sale agreements are potentially dilutive at period end under the treasury stock method, the impact of such dilution is disclosed in the calculation included in note 18. In the first quarter of 2020, the Company issued 1.7 million shares of common stock in connection with the redemption of 1.7 million limited partnership units in CPLP. Each of the redeemed limited partnership units in CPLP was "paired" with a share of limited voting preferred stock with a par value of $1 per share. The shares of limited voting preferred stock were automatically redeemed by the Company without consideration when their paired limited partnership unit in CPLP was redeemed. After this redemption, the Company no longer has any preferred stock outstanding. Ownership Limitations — In order to minimize the risk that the Company will not meet one of the requirements for qualification as a REIT, the Company's Articles of Incorporation include certain restrictions on the ownership of more than 3.9% of the Company’s total common and preferred stock, subject to waiver by the Board of Directors.

REVENUE RECOGNITION	REVENUE RECOGNITION The Company categorizes its primary sources of revenue into revenue from contracts with customers and other revenue accounted for as leases under ASC 842 as follows: • Rental property revenues consist of (1) contractual revenues from leases recognized on a straight-line basis over the term of the respective lease; (2) percentage rents recognized once a specified sales target is achieved; (3) parking revenue; (4) termination fees; and (5) the reimbursement of the tenants' share of real estate taxes, insurance, and other operating expenses. The Company's leases typically include renewal options and are classified and accounted for as operating leases. Rental property revenues are accounted for in accordance with the guidance set forth in ASC 842. • Fee income consists of development fees, management fees, and leasing fees earned from unconsolidated joint ventures and from third parties. Fee income is accounted for in accordance with the guidance set forth in ASC 606. For the years ended December 31, 2021, 2020, and 2019, the Company recognized rental property revenues of $739.1 million, $721.9 million, and $628.8 million, respectively, of which $199.0 million, $188.1 million, and $176.6 million, respectively, represented variable rental revenue.

Stock-Based Compensation	Dec. 31, 2021
Share-based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION The Company has several types of stock-based compensation — stock options, restricted stock, restricted stock units ("RSUs"), and the ESPP. The Company's compensation expense in 2021 relates to restricted stock and RSUs awarded in 2021, 2020, 2019, and 2018. Restricted stock and the 2021 and 2020 RSUs are equity-classified awards (settled in shares of the Company) for which compensation expense per share is fixed. The 2019 and 2018 RSUs are liability-classified awards (settled in cash) for which the expense fluctuates from period to period dependent, in part, on the Company's stock price. For 2021, 2020, and 2019, stock-based compensation expense, net of forfeitures, was recorded as follows (in thousands): 2021 2020 2019 Equity-classified awards: Restricted stock $ 2,677 $ 2,555 $ 2,468 Market-based RSUs 2,532 1,255 — Performance-based RSUs 881 428 — Director grants 890 1,060 1,362 6,980 5,298 3,830 Liability-classified awards Market-based RSUs 1,942 2,498 6,306 Performance-based RSUs 456 258 1,814 Service-based RSUs 690 633 1,040 Dividend equivalent units 564 675 740 3,652 4,064 9,900 Total stock-based compensation expense $ 10,632 $ 9,362 $ 13,730 On April 23, 2019, the Company's stockholders approved the Cousins Properties Incorporated 2019 Omnibus Incentive Stock Plan (the "2019 Plan") which allows the Company to issue awards of stock options, stock grants, or stock appreciation rights to employees and directors. The 2019 Plan also allows the Company to issue awards to employees that are paid in cash or stock on the vesting date in an amount equal to the fair market value, as defined, of one share of the Company’s stock. As of December 31, 2021, 3,577,897 shares were authorized to be awarded pursuant to the 2019 Plan. The Company also maintains the Cousins Properties Incorporated 2009 Incentive Stock Plan (the "2009 Plan") and the Cousins Properties Incorporated 2005 Restricted Stock Unit Plan (the “RSU Plan”), as amended, although no further issuances are permitted under the 2009 Plan or RSU Plan. Equity-Classified Awards During 2021 and 2020, the Company granted three types of equity-classified awards to key employees: (1) RSUs based on the total stockholder return of the Company, as defined, relative to that of office peers included in the SNL US Office REIT Index (the "Market-based RSUs"), (2) RSUs based on the ratio of cumulative funds from operations per share to targeted cumulative funds from operations per share (the “Performance-based RSUs”), (3) and restricted stock. During 2019, the only equity-based awards granted were restricted stock. The RSU awards are equity-classified awards to be settled in stock with issuance dependent upon the attainment of required service, market, and performance criteria. For the Market-based RSUs the Company expenses an estimate of the fair value of the awards on the grant date, calculated using a Monte Carlo valuation at grant date, ratably over the vesting period, adjusting only for forfeitures when they occur. The expense of these Market-based RSUs is not adjusted for the number of awards that actually vest. For the Performance-based RSUs the Company expenses the awards over the vesting period using the grant date fair market value of the Company's stock on the grant date. The expense is recognized ratably over the vesting period and adjusted each quarter based on the number of shares expected to vest and for forfeitures when they occur. The measurement period for both RSUs is three years starting on January 1 of the year of issuance and ending on December 31. The ultimate settlement of these awards can range from 0% to 200% of the targeted number of units depending on the achievement of the market and performance metrics described above. The Company estimates future expense for all equity-classified RSUs outstanding at December 31, 2021 to be $4.7 million (using estimated vesting percentages for performance-based RSUs as of December 31, 2021), which will be recognized over a weighted-average period of 1.6 years. In 2021, 2020, and 2019, the Company issued 102,262; 71,421; and 65,824 shares, respectively, of restricted stock to employees, which vest ratably over three years from the issuance date. In 2021, 2020, and 2019, the Company also issued 34,912; 34,059; and 37,166 shares, respectively, of stock to independent members of the board of directors which vested immediately on the issuance date. The Company records restricted stock in common stock and additional paid-in capital at fair value on the grant date, with the offsetting deferred compensation also recorded in additional paid-in capital. The Company records compensation expense over the vesting period. As of December 31, 2021, the Company had $2.7 million of unrecognized compensation cost included in additional paid-in capital related to restricted stock, which will be recognized over a weighted average period of 1.6 years. The total vesting date fair value of the restricted stock which vested during 2021, 2020, and 2019 was $1.9 million, $3.2 million, and $2.6 million, respectively. The following table summarizes equity-classified award activity for the years ended December 31, 2021, 2020, and 2019 (shares in thousands): 2021 2020 2019 Shares Weighted Average Fair Market Value at Grant Shares Weighted Average Fair Market Value at Grant Shares Weighted Average Fair Market Value at Grant Shares unvested at beginning of the year 221 $41.90 141 $34.81 148 $33.08 Granted 248 $35.44 173 $44.13 66 $35.64 Vested (58) $37.47 (82) $34.69 (72) $34.09 Forfeited (2) $39.27 (11) $41.10 (1) $34.46 Shares unvested at end of year 409 $38.63 221 $41.90 141 $34.81 The Monte Carlo valuation used to determine the grant date fair value of the equity-classified Market-based RSUs included the following assumptions for those RSUs granted in 2021 and 2020: 2021 2020 Volatility (1) 37.5 % 18.0 % Risk-free rate (2) 0.17 % 1.34 % Stock beta (3) 1.04 % 1.04 % (1) Based on historical volatility over three years using daily stock price. (2) Reflects the yield on three-year Treasury bonds. (3) Betas are calculated with up to three years of daily stock price data. Dividend equivalents for the 2021 and 2020 RSUs will be settled in shares of the Company's common stock based upon the number of units vested. The Company accrues for these dividend equivalent units over the measurement period as dividends are declared and they are included in distributions in excess of cumulative net income on the consolidated balance sheet. The targeted number of non-vested equity-classified RSUs at December 31, 2021 is 242,728. All shares of restricted stock receive dividends and have voting rights during the vesting period. At December 31, 2021, the Company had no stock options outstanding to key employees and outside directors. In 2021, 2020, and 2019, there were no stock option grants to employees or directors, and the Company recognized no compensation expense related to stock options. During 2021 and 2020, the Company issued 24,626 and 12,373 shares for option exercises, respectively. The following is a summary of stock option activity for the years ended December 31, 2021, 2020, and 2019 (options in thousands): 2021 2020 2019 Number of Options Weighted Average Exercise Price Per Option Number of Options Weighted Average Exercise Price Per Option Number of Options Weighted Average Exercise Price Per Option Outstanding at beginning of year 28 $25.55 67 $23.13 114 $24.00 Exercised (28) $25.55 (37) $21.28 (42) $25.59 Forfeited/expired — — (2) $22.76 (5) $25.32 Outstanding at end of year — — 28 $25.55 67 $23.13 Liability-Classified Awards During 2019, the Company awarded three types of liability-classified awards to key employees: (1) Market-based RSUs, (2) Performance-based RSUs, (3) and Service-based RSUs. The 2019 RSU awards are liability-classified awards to be settled in cash with payment dependent upon the attainment of required market, performance, and service criteria. The vesting period for the 2019 RSUs is three years. For the 2019 Market-based RSUs, the Company expenses an estimate of the fair value of the awards over the vesting period using a quarterly Monte Carlo valuation. For the 2019 Performance-based RSUs, the Company expenses the awards over the vesting period using the fair market value of the Company’s stock at the reporting date multiplied by the anticipated number of units to be paid based on the current estimate of what the ratio is expected to be upon vesting. For the 2019 Service-based RSUs, the Company expenses the awards ratably over the vesting period using the fair market value of the Company's stock at the reporting date. The following table summarizes the Company's liability-classified award activity during the years ended December 31, 2021, 2020, and 2019 (shares in thousands): 2021 2020 2019 Shares Shares Shares Shares unvested at beginning of the year 135 316 276 Granted — — 136 Vested (92) (172) (95) Forfeited — (9) (1) Shares unvested at end of year 43 135 316 Market-based and Performance-based RSUs, dividend equivalent units will be paid based on the percentage vested. For the 2019 RSU grants, dividend equivalent units will be paid out at the time of vesting. The Company accrues and expenses for these dividend equivalent units over the service period as dividends are declared, based on the latest projected vesting percentage. For Service-based RSUs, dividend equivalent units will be paid based on the number of RSUs granted. For the 2019 time-vested RSU grants, dividend equivalent units will be paid out at the time of vesting. The Company accrues and expenses these dividend equivalent units over the service period as dividends are declared. The Company estimates future expense for all types of liability-classified RSUs outstanding at December 31, 2021 to be $539,000 (using stock prices as of December 31, 2021), which will be recognized over a weighted-average period of one year. During 2021, total cash paid for all types of liability-classified RSUs and related dividend payments was $7.2 million. Employee Stock Purchase Plan On October 26, 2021, the Company’s board of directors adopted the Employee Stock Purchase Plan ("ESPP"), subject to the approval of our stockholders. Pursuant to the ESPP, employees may contribute up to 15% of their cash compensation during annual purchase periods for the purchase of Cousins’ common stock up to an annual maximum of $21,250 per employee. On each purchase period ending November 30, participants’ individual account balances are used to acquire shares of common stock at 85% of the Company’s closing price as of December 1 (the beginning of the purchase period) or November 30 (the end of the purchase period), whichever is lower. As of December 31, 2021, 95 employees were enrolled in the plan with expected contributions for the purchase period ended November 30, 2022 of $640,000. As of December 31, 2021, the Company estimates future expense related to the open purchase period to be $177,000. As of and for the year ended December 31, 2021, no common stock has been purchased under the ESPP.

Reportable Segments

Segment Reporting [Abstract]
REPORTABLE SEGMENTS	REPORTABLE SEGMENTS The Company's segments are based on the method of internal reporting which classifies operations by property type and geographical area. The segments by property type are: Office and Non-Office. The segments by geographical region are: Atlanta, Austin, Charlotte, Dallas, Phoenix, Tampa, and other markets. Included in other markets are properties located in Chapel Hill, Houston, Nashville, Fort Worth (sold April 2021), and a property in Cherry Hill, New Jersey (sold February 2020). Included in Non-Office are retail and apartments in Chapel Hill and Atlanta as well as the College Street Garage in Charlotte. In 2021, with the sale of the Company's One South at the Plaza office property, the Company reassessed the segment for the College Street Garage and began to treat it as Non-Office for all periods presented. These reportable segments represent an aggregation of operating segments reported to the Chief Operating Decision Maker based on similar economic characteristics that include the type of property and the geographical location. Each segment includes both consolidated operations and the Company's share of joint venture operations. Company management evaluates the performance of its reportable segments in part based on net operating income (“NOI”). NOI represents rental property revenues, less termination fees, less rental property operating expenses. NOI is not a measure of cash flows or operating results as measured by GAAP, is not indicative of cash available to fund cash needs, and should not be considered an alternative to cash flows as a measure of liquidity. All companies may not calculate NOI in the same manner. The Company considers NOI to be an appropriate supplemental measure to net income as it helps both management and investors understand the core operations of the Company's operating assets. NOI excludes corporate general and administrative expenses, reimbursed expenses, interest expense, depreciation and amortization, impairments, gains/loss on sales of real estate, gain/loss on extinguishment of debt, transaction costs and other non-operating items. Segment net income, amount of capital expenditures, and total assets are not presented in the following tables because management does not utilize these measures when analyzing its segments or when making resource allocation decisions. Information on the Company's segments along with a reconciliation of NOI to net income for years ended December 31, 2021, 2020, and 2019 are as follows (in thousands): Year Ended December 31, 2021 Office Non-Office Total Revenues: Atlanta $ 268,953 $ 1,459 $ 270,412 Austin 247,806 — 247,806 Charlotte 74,702 2,700 77,402 Dallas 17,670 — 17,670 Phoenix 50,292 — 50,292 Tampa 59,614 — 59,614 Other markets 39,403 5,257 44,660 Total segment revenues 758,440 9,416 767,856 Less: Company's share of rental property revenues from unconsolidated joint ventures (22,075) (6,718) (28,793) Total rental property revenues $ 736,365 $ 2,698 $ 739,063 Year Ended December 31, 2020 Office Non-Office Total Revenues: Atlanta $ 255,594 $ 602 $ 256,196 Austin 210,229 — 210,229 Charlotte 94,520 2,017 96,537 Dallas 18,143 — 18,143 Phoenix 50,671 — 50,671 Tampa 54,261 — 54,261 Other markets 59,285 4,895 64,180 Total segment revenues 742,703 7,514 750,217 Less: Company's share of rental property revenues from unconsolidated joint ventures (22,837) (5,497) (28,334) Total rental property revenues $ 719,866 $ 2,017 $ 721,883 Year Ended December 31, 2019 Office Non-Office Total Revenues: Atlanta $ 242,209 $ 8 $ 242,217 Austin 160,196 — 160,196 Charlotte 120,214 — 120,214 Dallas 9,421 — 9,421 Phoenix 51,586 — 51,586 Tampa 54,216 — 54,216 Other markets 38,732 4,630 43,362 Total segment revenues 676,574 4,638 681,212 Less: Company's share of rental property revenues from unconsolidated joint ventures (47,823) (4,638) (52,461) Total rental property revenues $ 628,751 $ — $ 628,751 NOI by reportable segment for the years ended December 31, 2021, 2020, and 2019 are as follows (in thousands): Year Ended December 31, 2021 Office Non-Office Total Net Operating Income: Atlanta $ 176,793 $ 622 $ 177,415 Austin 146,923 — 146,923 Charlotte 53,294 1,351 54,645 Dallas 14,014 — 14,014 Phoenix 36,244 — 36,244 Tampa 38,305 — 38,305 Other markets 22,791 3,383 26,174 Total Net Operating Income $ 488,364 $ 5,356 $ 493,720 Year Ended December 31, 2020 Office Non-Office Total Net Operating Income: Atlanta $ 172,588 $ (49) $ 172,539 Austin 125,215 — 125,215 Charlotte 63,876 1,327 65,203 Dallas 14,586 — 14,586 Phoenix 37,358 — 37,358 Tampa 33,440 — 33,440 Other markets 34,346 3,347 37,693 Total Net Operating Income $ 481,409 $ 4,625 $ 486,034 Year Ended December 31, 2019 Office Non-Office Total Net Operating Income: Atlanta $ 158,093 $ (48) $ 158,045 Austin 93,311 — 93,311 Charlotte 77,082 — 77,082 Dallas 7,473 — 7,473 Phoenix 37,247 — 37,247 Tampa 33,586 — 33,586 Other markets 21,939 3,107 25,046 Total Net Operating Income $ 428,731 $ 3,059 $ 431,790 The following reconciles Net Income to Net Operating Income for each of the periods presented (in thousands): Year Ended December 31, 2021 2020 2019 Net income $ 278,996 $ 238,114 $ 152,683 Net operating income from unconsolidated joint ventures 19,223 18,836 32,413 Fee income (15,559) (18,226) (28,518) Termination fee income (5,105) (3,835) (7,228) Other income (451) (231) (246) Reimbursed expenses 2,476 1,580 4,004 General and administrative expenses 29,321 27,034 37,007 Interest expense 67,027 60,605 53,963 Impairment — 14,829 — Depreciation and amortization 288,092 288,648 257,149 Transaction costs — 428 52,881 Other expenses 2,131 2,091 1,109 Income from unconsolidated joint ventures (6,801) (7,947) (12,666) Gain on sale of investment in unconsolidated joint ventures (13,083) (45,767) — Gain on sale of investment properties (152,547) (90,125) (110,761) Net Operating Income $ 493,720 $ 486,034 $ 431,790

Significant Accounting Policies (Policies)	Dec. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The consolidated financial statements include the accounts of the Company and its consolidated partnerships and wholly-owned subsidiaries. Intercompany transactions and balances have been eliminated in consolidation. The Company presents its financial statements in accordance with accounting principles generally accepted in the United States (“GAAP”) as outlined in the Financial Accounting Standard Board’s Accounting Standards Codification (the “Codification” or “ASC”). The Codification is the single source of authoritative accounting principles applied by nongovernmental entities in the preparation of financial statements in conformity with GAAP. For the three years ended December 31, 2021, there were no items of other comprehensive income. Therefore, the Company did not present comprehensive income.
Cost Capitalization, Depreciation and Amortization	Cost Capitalization: Costs related to planning, developing, leasing, and constructing a property, including costs of development personnel working directly on projects under development, are capitalized. In addition, the Company capitalizes interest to qualifying assets under development based on average accumulated expenditures outstanding during the period. In capitalizing interest to qualifying assets, the Company first uses the interest incurred on specific project debt, if any, and next uses the Company’s weighted average interest rate for non-project specific debt. The Company also capitalizes interest to investments accounted for under the equity method when the investee has property under development with a carrying value in excess of the investee’s borrowings. To the extent debt exists within an unconsolidated joint venture during the construction period, the venture capitalizes interest on that venture-specific debt. The Company capitalizes interest, real estate taxes, and certain operating expenses on the unoccupied portion of recently completed development properties until the date a project is substantially complete and held for occupancy, which is the earlier of (1) the date on which the project achieves 90% economic occupancy or (2) one year from cessation of major construction activity. Depreciation and Amortization: Real estate assets are stated at depreciated cost less impairment, if any. Buildings are depreciated over their estimated useful lives, which range generally from 30 to 42 years. The life of a particular building depends upon a number of factors including whether the building was developed or acquired and the condition of the building upon acquisition. Furniture, fixtures, and equipment are depreciated over their estimated useful lives of three
Impairment	Impairment: We review our real estate assets on a property-by-property basis for impairment. This review includes our operating properties, properties under development, and land holdings. The first step in this process is to determine whether an asset is considered to be held and used or held for sale, in accordance with accounting guidance. In order to be considered a real estate asset held for sale, we must, among other things, have the authority to commit to a plan to sell the asset in its current condition, have commenced the plan to sell the asset, and have determined that it is probable that the asset will sell within one year. If we determine that an asset is held for sale, we record an impairment loss if the fair value less costs to sell is less than the carrying amount. All real estate assets not meeting the held for sale criteria are considered to be held and used.
Acquisition of Real Estate Assets	Acquisition of Real Estate Assets: The Company evaluates all real estate acquisitions to determine if the transactions qualify as an acquisition of assets or of a business. If the Company determines that substantially all of the fair value is concentrated in a single identifiable asset or group of similar assets, the Company will account for the acquisition as an acquisition of assets and not a business. If the Company determines that there is no single or group of assets that make up substantially all of the fair value of assets acquired, the Company must determine whether the acquired set of assets includes an input and substantial processes which create an output. Based on the facts of the transactions and guidance in ASC 805, if the Company determines that an input and substantial processes that create an output are present, the Company will account for the acquisition as an acquisition of a business. For acquisitions that are accounted for as an acquisition of an asset, the Company records the acquired tangible and intangible assets and assumed liabilities based on each asset and liability's relative fair value at the acquisition date to the total purchase price plus capitalized acquisition costs. For acquisitions that are accounted for as an acquisition of a business, the Company records the acquired tangible and intangible assets and assumed liabilities at fair value at the acquisition date. The acquired assets and assumed liabilities for an operating property acquisition generally include but are not limited to: land, buildings and improvements, and identified tangible and intangible assets and liabilities associated with in-place leases, including leasing costs, value of above-market and below-market tenant leases, value of above-market and below-market ground leases, acquired in-place lease values, and tenant relationships, if any. The fair value of land is derived from comparable sales of land within the same submarket and/or region. The fair value of buildings and improvements, tenant improvements, and leasing costs are based upon current market replacement costs and other relevant market rate information. The fair value of the above-market or below-market component of an acquired lease is based upon the present value (calculated using a market discount rate) of the difference between (1) the contractual rents to be paid pursuant to the lease over its remaining term and (2) management’s estimate of the rents that would be paid using fair market rental rates and rent escalations at the date of acquisition over the remaining term of the lease. The amounts recorded for above-market and below-market ground leases are included in intangible liabilities and intangible assets, respectively, and are amortized on a straight-line basis into rental property revenues over the remaining terms of the applicable leases. The fair value of acquired in-place leases is derived based on management’s assessment of lost revenue and costs incurred for the period required to lease the “assumed vacant” property to the occupancy level when purchased. The amount recorded for acquired in-place leases is included in intangible assets and amortized as an increase to depreciation and amortization expense over the remaining term of the applicable leases.
Investment in Joint Ventures	Investment in Joint Ventures For joint ventures that the Company does not control, but over which it exercises significant influence, the Company uses the equity method of accounting. The Company's judgment with regard to its level of influence or control of an entity involves consideration of various factors including the form of its ownership interest; its representation in the entity's governance; its ability to participate in policy-making decisions; and the rights of other investors to participate in the decision-making process, to replace the Company as manager, and/or to liquidate the venture. These ventures are recorded at cost and adjusted for equity in earnings (losses) and cash contributions and distributions. Any difference between the carrying amount of these investments on the Company’s consolidated balance sheet and the underlying equity in net assets on the joint venture’s balance sheet is adjusted as the related underlying assets are depreciated, amortized, or sold. The Company generally allocates income and loss from an unconsolidated joint venture based on the venture's distribution priorities, which may be different from its stated ownership percentage.
Noncontrolling Interest	Noncontrolling Interest The Company consolidates CPLP and certain joint ventures in which it owns a controlling interest. In cases where the entity’s documents do not contain a required redemption clause, the Company records the partner’s share of the entity in the equity section of the balance sheets in nonredeemable noncontrolling interests. In cases where the entity’s documents contain a provision requiring the Company to purchase the partner’s share of the venture at a certain value upon demand or at a future date, if any, the Company records the partner’s share of the entity in redeemable noncontrolling interests on the balance sheets. The outside partners' interests in CPLP are redeemable upon demand into cash or shares of common stock of the Company at the Company's sole discretion. Therefore, noncontrolling interests associated with CPLP are considered nonredeemable noncontrolling interests. The noncontrolling partners' share of all consolidated entities' income is reflected in net income attributable to noncontrolling interest on the statements of operations.
Revenue Recognition	Revenue Recognition Rental Property Revenues: The Company recognizes contractual revenues from leases on a straight-line basis over the term of the respective lease. If we determine the improvements are our assets, we capitalize the cost of the improvements and recognize depreciation expense associated with such improvements over the shorter of the estimated useful life or the term of the lease. If the improvements are tenant assets, we defer the cost of improvements funded by us as a lease incentive asset and amortize it as a reduction of rental revenue over the term of the lease. Our determination of whether improvements are our assets or tenant assets also affects when we commence revenue recognition in connection with a lease. The Company records deferred revenue for the portion of company owned tenant improvements funded or reimbursed by tenants and amortizes this amount on a straight-line basis into rental income over the term of the related lease. As of December 31, 2021 and 2020, the Company had unamortized deferred income related to tenant funded tenant improvements of $30.2 million and $31.6 million, respectively, included in deferred income on the consolidated balance sheets. Fee Income: The Company recognizes development, management, and leasing fees as it satisfies the related performance obligations under the respective contracts. The Company recognizes development and leasing fees received from investments in unconsolidated joint ventures and related salaries and other direct costs incurred by the Company as income and expense based on the percentage of the joint venture which the Company does not own. Correspondingly, the Company adjusts its investment in unconsolidated joint ventures when fees are paid to the Company by a joint venture in which the Company has an ownership interest. Gain on Investment Property Transactions: The Company recognizes a gain on the sale of investment property at the time the buyer obtains control of the investment property. If the Company maintains any continuing involvement with the investment property, that continuing involvement is considered to be one or more additional performance obligations and additional gains or losses will be recognized as these performance obligations are satisfied. When the Company gains control of a previously unconsolidated investment accounted for under the equity method of accounting, it records a gain for the difference between the carrying value of its equity method investment and the fair value of that investment on the date control is gained.
Receivables	The Company makes valuation adjustments to all tenant-related accounts receivable based upon its estimate of the likelihood of collectibility of amounts due from the tenant. The amount of any valuation adjustment is based on the tenant’s credit and business risk, history of payment, and other factors considered by management.In limited circumstances to date, the Company has entered into lease amendments with certain tenants, a majority of which are small retail operators who have experienced disruptions in their business as a result of the COVID-19 pandemic. Some of these agreements forgive rents and extend the lease term for the equivalent number of months at the end of the original lease and others provide for forgiveness without extension. Rent forgiveness, with or without extensions, is accounted for as lease modifications, and the Company recognizes the effects over time through straight-line rent over the lease term. Other agreements provide for payment deferrals without extensions. The Company accounts for these deferral agreements as lease modifications and has included these deferred payments in deferred rents receivable on the accompanying consolidated balance sheets.
Income Taxes	Income Taxes The Company has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify as a REIT, the Company must distribute annually at least 90% of its adjusted taxable income, as defined in the Code, to its stockholders and satisfy certain other organizational and operating requirements. It is management’s current intention to adhere to these requirements and maintain the Company's REIT status. As a REIT, the Company generally will not be subject to federal income tax at the corporate level on the taxable income it distributes to its stockholders. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal income taxes at regular corporate rates and may not be able to qualify as a REIT for four subsequent taxable years. The Company may be subject to certain state and local taxes on its income and property, and to federal income taxes on its undistributed taxable income.
Stock Compensation	Stock Compensation The Company accounts for stock-based employee compensation using the fair value based method of accounting. We classify share-based payment awards granted in exchange for employee services as either equity awards or liability awards. Equity-classified awards are measured based on the fair value on the date of grant. Awards that are to be settled in cash are classified as liability awards. The value of all of the Company's share-based awards is recognized over the period during which an employee is required to provide services in exchange for the award - the requisite service period (usually the vesting period). No compensation costs are recognized for awards for which employees do not complete the requisite service period.
Earnings per Share	Earnings per Share Net income per share-basic is calculated as net income available to common stockholders divided by the weighted average number of common shares outstanding during the period, including nonvested restricted stock which has nonforfeitable dividend rights. Net income per share-diluted is calculated as net income available to common stockholders plus noncontrolling interests in CPLP divided by the diluted weighted average number of common shares outstanding during the period. Diluted weighted average number of common shares uses the same weighted average share number as in the basic calculation and adds the potential dilution that would occur if i) the outside units in CPLP were converted into the Company's common stock, ii) any stock options were exercised, iii) any forward sales contracts of our common stock were settled, and iv) equity-based restricted stock units ("RSUs") as well as shares to be issued under the Employee Stock Purchase Plan (“ESPP”) were vested and settled resulting in additional common shares outstanding, all calculated using the treasury stock method, as applicable. Stock options are dilutive when the average market price of the Company’s stock during the period exceeds the option exercise price. RSUs are dilutive if the shares to be granted (assuming the end of the reporting period is the end of the measurement of any required market and performance achievement) exceed the shares assumed to be repurchased under the treasury stock method (using related unamortized compensation costs as proceeds). Shares to be issued under the ESPP are dilutive if the estimated shares to be purchased under the plan based on current enrollment elections exceed the shares assumed to be repurchased under the treasury stock method (using both employee ESPP contributions and related unamortized compensation costs as proceeds). On January 1, 2021, the Company early adopted ASU 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)" ("ASU 2020-06"). The adoption of ASU 2020-06 could potentially impact the denominator in our diluted earnings per share calculation in the future. For the year ended December 31, 2021, it did not impact the denominator.
Cash and Cash Equivalents	Cash and Cash EquivalentsCash and cash equivalents include unrestricted cash and highly-liquid money market instruments. Highly-liquid money market instruments include securities and repurchase agreements with original maturities of three months or less, money market mutual funds, and United States Treasury Bills with maturities of 30 days or less.
Restricted Cash	Restricted Cash Restricted cash primarily includes escrow accounts held by lenders for reserves or to pay real estate taxes.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Reportable Segments	The Company's segments are based on the method of internal reporting which classifies operations by property type and geographical area. The segments by property type are: Office and Non-Office. The segments by geographical region are: Atlanta, Austin, Charlotte, Dallas, Phoenix, Tampa, and other markets. Included in other markets are properties located in Chapel Hill, Houston, Nashville, Fort Worth (sold April 2021), and a property in Cherry Hill, New Jersey (sold February 2020). Included in Non-Office are retail and apartments in Chapel Hill and Atlanta as well as the College Street Garage in Charlotte. In 2021, with the sale of the Company's One South at the Plaza office property, the Company reassessed the segment for the College Street Garage and began to treat it as Non-Office for all periods presented. These reportable segments represent an aggregation of operating segments reported to the Chief Operating Decision Maker based on similar economic characteristics that include the type of property and the geographical location. Each segment includes both consolidated operations and the Company's share of joint venture operations. Company management evaluates the performance of its reportable segments in part based on net operating income (“NOI”). NOI represents rental property revenues, less termination fees, less rental property operating expenses. NOI is not a measure of cash flows or operating results as measured by GAAP, is not indicative of cash available to fund cash needs, and should not be considered an alternative to cash flows as a measure of liquidity. All companies may not calculate NOI in the same manner. The Company considers NOI to be an appropriate supplemental measure to net income as it helps both management and investors understand the core operations of the Company's operating assets. NOI excludes corporate general and administrative expenses, reimbursed expenses, interest expense, depreciation and amortization, impairments, gains/loss on sales of real estate, gain/loss on extinguishment of debt, transaction costs and other non-operating items.
