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”). Through October 5, 2016, Cousins conducted all of its business on its own account or through wholly or partially owned entities, some of which were consolidated with Cousins and some of which were not consolidated and were accounted for under the equity method. One of the consolidated entities, Cousins TRS Services LLC ("CTRS") is a taxable entity which owns and manages its own real estate portfolio and performs certain real estate related services for other parties. In connection with a series of transactions with Parkway Properties, Inc. ("Parkway") and Parkway, Inc. ("New Parkway"), including a merger and spin-off, Cousins Properties LP ("CPLP") was formed. On October 6, 2016, the closing date of the merger with Parkway, Cousins contributed, or caused to be contributed, all of Parkway's and Cousins' assets and liabilities not pertaining to the ownership of real properties in Houston, Texas and certain other businesses of Parkway to CPLP, including CTRS, and began conducting substantially all of its operations through CPLP. Cousins owns approximately 98% of CPLP and consolidates CPLP. 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 Sunbelt markets with a focus on Georgia, Texas, and North Carolina. As of December 31, 2016 , the Company’s portfolio of real estate assets consisted of interests in 16.2 million square feet of office space and 786,000 square feet of mixed-use 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, 2016 , there were no items of other comprehensive income. Therefore, no presentation of comprehensive income is required. 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. At December 31, 2016, the Company had a joint venture with Callaway Gardens Resort, Inc. (“Callaway”) for the development of residential lots, which was funded fully through Company contributions. Callaway had the right to receive returns, but no obligation to fund any costs or absorb any losses. The Company was the sole decision maker for the venture and the development manager. The Company determined that the joint venture with Callaway was a VIE, and the Company was the primary beneficiary. Therefore, the Company consolidated this joint venture. In January 2017, the Company withdrew from the joint venture and, as a result, recorded an impairment loss of $4.5 million in 2016 which is included in other expense in the consolidated statements of operations. As of December 31, 2016 and 2015 , Callaway had total assets of $-0- and $4.6 million , respectively, and no significant liabilities. The Company also considers CPLP to be a VIE with the Company as the primary beneficiary. Recently Issued Accounting Standards : In 2015, the FASB issued ASC 2015-02 "Consolidation (Topic 810): Amendments to the Consolidation Analysis." All legal entities are subject to reevaluation under the revised consolidation model. The amendment modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities or voting interest entities. It also eliminates the presumption that a general partner should consolidate a limited partnership. The guidance is effective for public entities with periods beginning after December 15, 2015 with early adoption permitted. The Company adopted this guidance effective January 1, 2016, and it did not have material impact on the consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting." Under this ASU, the additional paid-in capital pool is eliminated, and an entity recognizes all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement. This ASU also eliminated the requirement to defer recognition of an excess tax benefit until all benefits are realized through a reduction to taxes payable. This ASU also changes the treatment of excess tax benefits as operating cash flows in the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016 with early adoption permitted. The Company expects to adopt this guidance effective January 1, 2017, and is currently assessing the potential impact of adopting the new guidance. In February 2016, the Financial Accounting Standards Board issued ASU 2016-02, "Leases," which amends the existing standards for lease accounting by requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting and reporting. The new standard will require lessees to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months and classify such leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method (finance leases) or on a straight-line basis over the term of the lease (operating leases). Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. ASU 2016-02 supersedes previous leasing standards. The guidance is effective for the fiscal years beginning after December 15, 2018 with early adoption permitted. The Company expects to adopt this guidance effective January 1, 2019, and is currently assessing the potential impact of adopting the new guidance. The Company expects to adopt this guidance using the " modified retrospective" method effective January 1, 2019. In the first quarter of 2016, the Company adopted ASU 2015-03, "Simplifying the Presentation of Debt Costs" ("ASU 2015-03"). In accordance with ASU 2015-03, the Company began recording deferred financing costs related to its mortgage notes payable as a reduction in the carrying amount of its notes payable on the consolidated balance sheets. The Company reclassified $2.5 million in deferred financing costs from other assets to notes payable in its December 31, 2015 consolidated balance sheet to conform to the current period's presentation. Deferred financing costs related to the Company’s unsecured revolving credit facility continue to be included in other assets within the Company’s balance sheets in accordance with ASU 2015-15 "Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements." In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers." Under the new guidance, companies will recognize revenue when the seller satisfies a performance obligation, which would be when the buyer takes control of the good or service. This new guidance could result in different amounts of revenue being recognized and could result in revenue being recognized in different reporting periods than under the current guidance. The new guidance specifically excludes revenue associated with lease contracts. ASU 2015-14, "Revenue from Contracts with Customers," was subsequently issued modifying the effective date to periods beginning after December 15, 2017, with early adoption permitted for periods beginning after December 15, 2016. The standard allows for either "full retrospective" adoption, meaning the standard is applied to all of the periods presented, or "modified retrospective" adoption, meaning the standard is applied only to the most recent period presented in the financial statements. The Company is currently assessing this guidance for future implementation and potential impact of adoption. The Company expects to adopt this guidance using the "modified retrospective" method effective January 1, 2018. In August 2014, the FASB issued ASU 205-40, "Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern," which requires management of all entities to evaluate whether there are conditions and events that raise substantial doubt about the entity's ability to continue as a going concern within one year after the financial statements are issued. The Company adopted ASU 205-40 as of December 31, 2016. In January 2017, the FASB issued ASU 2017-01, "Clarifying the Definition of a Business," which provides a more narrow definition of a business to be used in determining the accounting treatment of an acquisition. As a result, many acquisitions that previously qualified as business combinations will be treated as asset acquisitions. For asset acquisitions, acquisition costs may be capitalized, and the purchase price may be allocated on a relative fair value basis. ASU 2017-01 is effective prospectively for the Company on January 1, 2018, with early adoption permitted. The Company expects that most of its future acquisitions will qualify as asset acquisitions. Certain prior year amounts have been reclassified to conform with current year presentation on the consolidated statements of operations and the consolidated statements of equity. Separation expenses on the consolidated statements of operations have been reclassified from general and administrative expenses to other expenses. On the consolidated statements of equity, all components of common stock issued pursuant to stock-based compensation are aggregated into one line item. These changes do not affect the previously reported total costs and expenses in the consolidated statements of operations or the total equity in the consolidated statements of equity for any period.

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 from the date a project is substantially complete to the earlier of (1) the date on which the project achieves 90% economic occupancy or (2) one year after it is substantially complete. The Company capitalizes direct leasing costs related to leases that are probable of being executed. These costs include commissions paid to outside brokers, legal costs incurred to negotiate and document a lease agreement, and internal costs that are based on time spent by leasing personnel on successful leases. The Company allocates these costs to individual tenant leases and amortizes them over the related lease term. Impairment: For real estate assets that are considered to be held for sale according to accounting guidance or those that are distributed to stockholders in a spin-off, the Company records impairment losses if the fair value of the asset or disposal group net of estimated selling costs is less than the carrying amount. For those long-lived assets that are held and used according to accounting guidance, management reviews each asset for the existence of any indicators of impairment. If indicators of impairment are present, the Company calculates the expected undiscounted future cash flows to be derived from such assets. If the undiscounted cash flows are less than the carrying amount of the asset, the Company reduces the asset to its fair value and records an impairment loss. Acquisition of Real Estate Assets: The Company records the acquired tangible and intangible assets and assumed liabilities of operating property acquisitions 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 in-place lease is based upon the present value (calculated using a market discount rate) of the difference between (i) the contractual rents to be paid pursuant to the lease over its remaining term and (ii) 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 losses, if any. Buildings are depreciated over their estimated useful lives, which range generally from 24 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 to five years. Tenant improvements, leasing costs and leasehold improvements are amortized over the term of the applicable leases or the estimated useful life of the assets, whichever is shorter. The Company accelerates the depreciation of tenant assets if it estimates that the lease term will end prior to the termination date. This acceleration may occur if a tenant files for 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. Discontinued Operations: Beginning in the second quarter 2014, only assets held for sale or disposals representing strategic shifts in operations are reflected in discontinued operations. Prior to 2014, the Company classified the results of operations of all properties that were sold or otherwise qualified as held for sale as discontinued operations if the property's operations were expected to be eliminated from ongoing operations and the Company would not have any significant continuing involvement in the operations of the property after the sale. During 2015, there were no held for sale assets or disposals that represented a strategic shift in operations. During 2016, the Company spun-off the combined operations of the Company's and Parkway's Houston assets into a separate public company. The Company considered this disposition to be a strategic shift in operations and reclassified the historical operations of its Houston business into discontinued operations on the consolidated statements of operations. The Company ceases depreciation of a property when it is categorized as held for sale. 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 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, 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 into shares of cash or common stock of the Company in 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. Certain of these 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 2016 , 2015 , and 2014 , the Company recognized $90.2 million , $93.3 million , and $86.0 million , respectively, in revenues, including discontinued operations, from tenants related to operating expenses. 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. Fee Income: The Company recognizes development, management and leasing fees when earned. The Company recognizes development and leasing fees received from 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 the investment in unconsolidated joint ventures asset when fees are paid to the Company by a joint venture in which the Company has an ownership interest. See note 6 for more information related to fee income recognized from unconsolidated joint ventures. Gain on Sale of Investment Properties : The Company recognizes a gain on sale of investment property when the sale of a property is consummated, the buyer’s initial and continuing investment is adequate to demonstrate commitment to pay, any receivable obtained is not subject to future subordination, the usual risks and rewards of ownership are transferred, and the Company has no substantial continuing involvement with the property. If the Company has a commitment to the buyer and that commitment is a specific dollar amount, this commitment is accrued and the gain on sale that the Company recognizes is reduced. If the Company has a construction commitment to the buyer, management makes an estimate of this commitment, defers a portion of the profit from the sale, and recognizes the deferred profit as or when the commitment is fulfilled. Income Taxes Cousins has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify as a REIT, Cousins 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 Cousins’ REIT status. As a REIT, Cousins generally will not be subject to federal income tax at the corporate level on the taxable income it distributes to its stockholders. If Cousins fails to qualify as a REIT in any taxable year, it will be subject to federal income taxes at regular corporate rates (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years. Cousins 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-Based Compensation The Company has several types of stock-based compensation plans. These plans are described in note 13, as are the accounting policies by type of award. The Company recognizes compensation expense, net of forfeitures, arising from share-based payment arrangements granted to employees and directors in general and administrative expense in the statements of operations over the related awards’ vesting period, which may be accelerated under the Company’s retirement feature. Earnings per Share (“EPS”) 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 the outside units in CPLP were converted into the Company's common stock and stock options (or any other contracts to issue common stock) were exercised and resulted in additional common shares outstanding, calculated using the treasury stock method. The numerator is reduced for the effect of preferred dividends in both the basic and diluted net income per share calculations. Stock options are dilutive when the average market price of the Company’s stock during the period exceeds the option exercise price. Cash and Cash Equivalents and Restricted Cash Cash and cash equivalents include 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 primarily represents amounts restricted under debt agreements for future capital expenditures or for specific future operating costs. 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.

Business Combinations [Abstract]
TRANSACTIONS WITH PARKWAY PROPERTIES, INC.	TRANSACTIONS WITH PARKWAY PROPERTIES, INC. On October 6, 2016, pursuant to the Agreement and Plan of Merger, dated April 28, 2016, (as amended or supplemented from time to time, the “Merger Agreement”), by and among Cousins, Parkway and subsidiaries of Cousins and Parkway, Parkway merged with and into a wholly-owned subsidiary of the Company (the "Merger"), with this subsidiary continuing as the surviving corporation of the Merger. In accordance with the terms and conditions of the Merger Agreement, each outstanding share of Parkway common stock and each outstanding share of Parkway limited voting stock was converted into 1.63 shares of Cousins common stock or limited voting preferred stock, respectively. In the Merger, former Parkway common stockholders received approximately 183 million shares of Cousins common stock and Parkway limited voting stockholders received approximately 7 million shares of Cousins limited voting preferred stock. On October 7, 2016, pursuant to the Merger Agreement and the Separation, Distribution and Transition Services Agreement, dated as of October 5, 2016 (the "Separation Agreement"), by and among Cousins, Parkway, New Parkway, and certain other parties thereto, Cousins distributed pro rata to its common and limited voting preferred stockholders, including legacy Parkway common and limited voting stockholders, all of the outstanding shares of common and limited voting stock, respectively, of New Parkway, a newly-formed entity that contains the combined businesses relating to the ownership of real properties in Houston, Texas and certain other businesses of Parkway (the "Spin-Off"). In the Spin-Off, Cousins distributed one share of New Parkway common or limited voting stock for every eight shares of common or limited voting preferred stock of Cousins held of record as of the close of business on October 6, 2016. As a result of the Spin-Off, New Parkway is now an independent public company, and its common stock is listed under the symbol "PKY" on the New York Stock Exchange. In connection with the Merger and Spin-Off, CPLP was formed. As a result of a series of transactions undertaken pursuant to the Separation Agreement (the "Reorganization"), occurring after the Merger but prior to the Spin-Off, substantially all of Parkway's and the Company's assets and liabilities not pertaining to the ownership of real properties in Houston, Texas and certain other businesses of Parkway, were contributed to CPLP. As a result of the Merger and Spin-Off, substantially all of the Company's post-Merger, post-Spin-Off activities are conducted through CPLP. Approximately 98% of the partnership units of CPLP are owned by the Company, and approximately 2% are owned by legacy outside unit holders of Parkway LP (the "Outside Unit Holders"). Ownership of partnership units in CPLP will generally entitle the holder to share in cash distributions from, and in the profits and losses of, CPLP in proportion to such holder's percentage ownership. The Company acts as the general partner in CPLP and has the exclusive right and full authority and responsibility to manage and operate CPLP's business. Limited partners generally do not have any right to participate in or exercise control or management power over the business and affairs of CPLP. Limited partners may redeem partnership units for cash, or at the Company's election, shares of Cousins' common stock on a one -for-one basis, at any time beginning twelve months following the date of the initial issuance of the partnership units, except for partnership units issued in connection with the Reorganization, which may be redeemed at any time. The Company consolidates the accounts and operations of CPLP in its financial statements. The acquisition has been accounted for using the acquisition method of accounting in accordance with Accounting Standards Codification, or ASC, 805, Business Combinations , 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 October 5, 2016, the day immediately prior to the closing of the Merger, of $10.19 per share. Based on the shares issued in the transaction and on the units of CPLP effectively issued to the Outside Unit Holders in the transaction, the total fair value of the assets and liabilities assumed in the Merger was $2.0 billion . The Company incurred $24.5 million in expenses related to the merger during the year ended December 31, 2016. Management engaged a third party valuation specialist to assist with the fair value assessment, which included an allocation of the purchase price. The third party used cash flow analysis as well as an income approach and a cost approach to determine the fair value of assets acquired. Based on additional information that may become available, subsequent adjustments may be made to the purchase price allocation within the allocation period, which typically does not exceed one year. The purchase price was allocated as follows (in thousands): Real estate assets $ 3,441,859 Cash 63,193 Restricted cash 30,560 Notes and other receivables 36,388 Investment in unconsolidated joint ventures 58,875 Intangible assets 330,221 Other assets 10,549 $ 3,971,645 Notes payable $ 1,473,810 Accounts payable and accrued expenses 136,934 Intangible liabilities 106,480 Other liabilities 12,076 Nonredeemable noncontrolling interests (excluding CPLP) 292,337 $ 2,021,637 Total purchase price $ 1,950,008 In the Merger, the Company acquired an interest in a joint venture which it consolidated because it controlled the operations of the joint venture. The outside interests associated with this joint venture are included in noncontrolling interests in the above purchase price allocation. In December 2016, the Company purchased the outside partner's interest in the joint venture for $279 million . The Merger accounted for $68.7 million of consolidated revenue and $9.0 million in consolidated net income as reported for 2016. The following unaudited supplemental pro forma information presented is based upon the Company's historical consolidated statements of operations, adjusted as if the Merger had occurred on January 1, 2015.

Fair value was calculated by discounting future cash flows from the notes receivable at estimated rates in which similar loans would have been made at December 31, 2016 and 2015 . The estimate of the rate, which is the most significant input in the discounted cash flow calculation, is intended to replicate notes of similar type and maturity. This fair value calculation is considered to be a Level 3 calculation under the accounting guidelines, as the Company utilizes internally generated assumptions regarding current interest rates at which similar instruments would be executed.

At December 31, 2016 , the Company’s investment in Wildwood was a credit balance of $1.1 million .

The Credit Facility may be expanded to $750 million at the election of the Company, subject to the receipt of additional commitments from the lenders and other customary conditions. The Credit Facility contains financial covenants that require, among other things, the maintenance of an unencumbered interest coverage ratio of at least 2.00 ; a fixed charge coverage ratio of at least 1.50 ; an overall leverage ratio of no more than 60% ; and a minimum shareholders' equity in an amount equal to $1.0 billion , plus a portion of the net cash proceeds from certain equity issuances. The Credit Facility also contains customary representations and warranties and affirmative and negative covenants, as well as customary events of default. The amounts outstanding under the Credit Facility may be accelerated upon the occurrence of any events of default. The interest rate applicable to the Credit Facility varies according to the Company’s leverage ratio, and may, at the election of the Company, be determined based on either (1) the current London Interbank Offered Rate (" LIBOR ") plus a spread of between 1.10% and 1.45% , 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 1.0% (the “Base Rate”), plus a spread of between 0.10% and 0.45% , based on leverage. The Company also pays an annual facility fee on the total commitments under the Credit Facility of between 0.15% and 0.30% based on leverage. At December 31, 2016 , the Credit Facility's spread over LIBOR was 1.1% . The amount that the Company may draw under the Credit Facility is a defined calculation based on the Company's unencumbered assets and other factors. The total available borrowing capacity under the Credit Facility was $365.0 million at December 31, 2016 . Term Loan During 2016, the Company obtained a $250 million unsecured term loan (the "Term Loan") that matures on December 2, 2021. The Term Loan contains financial covenants consistent with those of the Credit Facility. The interest rate applicable to the Term Loan varies according to the Company’s leverage ratio, and may, at the election of the Company, be determined based on either (1) the current London Interbank Offered Rate (" 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 1.0% (the “Base Rate”), plus a spread of between 0.00% and 0.75% , based on leverage. At December 31, 2016, the Term Loan's spread over LIBOR was 1.2% . Debt Associated with the Merger and Spin-Off In connection with the Merger, the Company assumed $635.2 million of mortgage debt (excluding $272.4 million of mortgage debt assumed and distributed in connection with the Spin-Off) at a weighted average stated interest rate of 5.2% . Subsequent to the Merger and before December 31, 2016, the Company repaid $251.9 million of this assumed mortgage debt, which included the legal defeasance of a $20.2 million mortgage loan. In connection with the Spin-Off, the Company distributed the Post Oak Central mortgage note to New Parkway on October 7, 2016. In the Merger, the Company assumed $550 million in Parkway unsecured term debt, received proceeds from a $350 million senior secured term loan and repaid the $550 million in unsecured term debt. In the Spin-Off, the Company distributed the $350 million senior secured term loan to New Parkway. Other Mortgage Loan Information In 2016, the Company had the following mortgage loan activity: • Entered into a $120.0 million non-recourse mortgage loan secured by Colorado Tower, a 373,000 square foot office building in Austin, Texas. The mortgage bears interest at a fixed annual rate of 3.45% and matures September 1, 2026. • Entered into a $150.0 million non-recourse mortgage loan secured by Fifth Third Center, a 698,000 square foot office building in Charlotte, North Carolina. The mortgage bears interest at a fixed annual rate of 3.37% and matures October 1, 2026. • Repaid the $98.1 million 191 Peachtree Tower mortgage loan in full in connection with a sale of the building and paid a $3.7 million prepayment penalty. In 2015, the Company prepaid, without penalty, the $14.2 million The Points at Waterview mortgage note. The note was scheduled to mature on January 1, 2016 . Other Debt Information The real estate and other assets of The American Cancer Society Center (the “ACS Center”) are restricted under the ACS Center loan agreement in that they are not available to settle debts of the Company. However, provided that the ACS Center loan has not incurred any uncured event of default, as defined in the loan agreement, the cash flows from the ACS Center, after payments of debt service, operating expenses and reserves, are available for distribution to the Company. The majority of the Company’s consolidated debt is fixed-rate long-term non-recourse mortgage notes payable. Assets with depreciated carrying values of $1.4 billion were pledged as security on the $995 million mortgage notes payable. As of December 31, 2016 , the weighted average maturity of the Company’s consolidated debt was 4.25 years. As a result of the Parkway Transactions, the Company assumed four non-recourse mortgage loans with an aggregate principal amount of $360.0 million that mature in 2017. In addition, the Company has one additional non-recourse mortgage loan with a principal balance of $127.5 million that matures in 2017. While the Company does not currently have the liquid funds available to satisfy the obligations, the Company expects to repay these loans when they mature with a combination of sources of capital including, but not limited to, asset sales, unsecured debt, mortgage loans on these or other properties, or issuance of common equity. At December 31, 2016 and 2015 , the estimated fair value of the Company’s notes payable was $1.4 billion and $738.1 million , respectively, calculated by discounting the debt's remaining contractual cash flows at estimated rates at which similar loans could have been obtained at December 31, 2016 and 2015 . 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.

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.

Equity [Abstract]
STOCKHOLDERS' EQUITY	STOCKHOLDERS' EQUITY In 2016, in connection with the Merger, the Company issued 6.9 million shares of limited voting preferred stock, par value $1 per share. Each share of limited voting preferred stock is "paired" with a limited partnership unit in CPLP. A share of Cousins limited voting preferred stock will be automatically redeemed by Cousins without consideration if such share's paired limited partnership unit in CPLP is transferred or redeemed. Holders of the limited voting preferred stock are entitled to one vote on the following matters only: the election of directors, any proposed amendment of the Company's Articles of Incorporation, any merger or other business combination of the Company, any sale of substantially all of the Company's assets, and any liquidation of the Company. Holders of limited voting preferred stock are not entitled to any dividends or distributions and the limited voting preferred stock is not convertible into or exchangeable for any other property or securities of the Company. In 2015, the Board of Directors of the Company authorized the repurchase of up to $100 million of its outstanding common shares. The plan expires on September 8, 2017 . The repurchases may be executed in the open market, through private negotiations, or in other transactions permitted under applicable law. The timing, manner, price and amount of any repurchases will be determined by the Company in its discretion and will be subject to economic and market conditions, stock price, applicable legal requirements and other factors. The share repurchase program may be suspended or discontinued at any time. Under this plan, through December 31, 2016 , the Company has repurchased 6.8 million shares of its common stock for a total cost of $61.5 million , including broker commissions. The share repurchases were funded from cash on hand, borrowings under the Company's Credit Facility, and proceeds from the sale of assets. The repurchased shares were recorded as treasury shares on the consolidated balance sheets. In 2014, the Company issued 26.7 million shares of common stock, in two offerings, resulting in net proceeds to the Company of $321.9 million , which includes customary legal, accounting, and other expenses. In 2014, the Company redeemed all outstanding shares of its 7.5% Series B Cumulative Redeemable Preferred Stock, par value $1 per share, for $25 per share or $94.8 million , excluding accrued dividends. In connection with this redemption, the Company decreased net income available for common stockholders by $3.5 million (non-cash), which represents the original issuance costs applicable to the shares redeemed. 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 Board of Directors.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION The Company maintains the 2009 Incentive Stock Plan (the “2009 Plan”), which allows the Company to issue awards of stock options, stock grants, or stock appreciation rights to employees and directors. As of December 31, 2016 , 2,293,403 shares were authorized to be awarded pursuant to the 2009 Plan. The Company also maintains the 2005 Restricted Stock Unit ("RSU")Plan, as amended, which allows the Company to issue awards to employees that are paid in cash on the vesting date in an amount equal to the fair market value, as defined, of one share of the Company’s stock. The Company has granted stock options, restricted stock, and restricted stock units to employees as discussed below. As a result of the Spin-Off, the number and strike price of stock options, shares of restricted stock, and the number of restricted stock units were adjusted to preserve the intrinsic value of the awards immediately prior to the Spin-Off using an adjustment ratio based on the market price of the Company's stock prior to the Spin-Off and the market price of the Company's stock subsequent to the Spin-Off pursuant to anti-dilution provisions of the 2009 Plan. Since these adjustments were considered to be a modification of the awards, the Company compared the fair value of the awards immediately prior to the Spin-Off to the fair value immediately after the Spin-Off to measure potential incremental stock-based compensation expense. The adjustments did not result in an increase in the fair value of the awards and, accordingly, the Company did not record incremental stock-based compensation expense. Stock Options At December 31, 2016 , the Company had 2,262,249 stock options outstanding to key employees and outside directors pursuant to the 2009 Plan. The Company typically uses authorized, unissued shares to provide shares for option exercises. The stock options have a term of ten years from the date of grant and have a vesting period of four years , except director stock options, which vest immediately. In 2016 , 2015 , and 2014 , there were no stock option grants to employees or directors. In 2016, in conjunction with the Merger, the Company granted 672,375 options to former Parkway key executives. These options vested immediately, and have a term of ten years from the date of grant. The Company calculated the fair value of these grants using the Black-Scholes option-pricing model, which requires the Company to provide certain inputs as follows: • The risk-free interest rate utilized is the interest rate on U.S. Treasury Strips or Bonds having the same life as the estimated life of the Company’s option awards. • Expected life of the options granted is estimated based on historical data reflecting actual hold periods plus an estimated hold period for unexercised options outstanding. • Expected volatility is based on the historical volatility of the Company’s stock over a period equal to the estimated option life. • The assumed dividend yield is based on the Company’s expectation of an annual dividend rate for regular dividends over the estimated life of the option. The weighted average fair value of options granted was $0.84 per option, and the Company computed the fair value of options granted using the Black-Scholes option pricing model with the following assumptions: Risk-free interest rate 1.37 % Assumed dividend yield 3.60 % Assumed lives of option awards (in years) 6.4 Assumed volatility 23.23 % The Company recorded $565,000 to additional paid-in capital for the fair value of the options granted as part of the Merger. During 2016 , 2015 , and 2014 , $0 , $15,000 and $140,000 , respectively, was recognized as compensation expense related to stock options. The Company does not anticipate recognizing any future compensation expense related to stock options outstanding beyond December 31, 2016 . During 2016 , total cash proceeds from the exercise of options equaled $13,000 . As of December 31, 2016 , the intrinsic value of the options outstanding and exercisable was $2.5 million . The intrinsic value is calculated using the exercise prices of the options compared to the market value of the Company’s stock. At December 31, 2016 and 2015 , the weighted-average contractual lives for the options outstanding and exercisable were 3.2 years and 2.3 years, respectively. The following is a summary of stock option activity for the years ended December 31, 2016 , 2015 , and 2014 : Number of Options (000s) Weighted Average Exercise Price Per Option Outstanding at December 31, 2013 3,078 $ 22.90 Exercised (206 ) 8.26 Forfeited/Expired (661 ) 28.18 Outstanding at December 31, 2014 2,211 22.69 Exercised (23 ) 8.02 Forfeited/Expired (425 ) 21.98 Outstanding at December 31, 2015 1,763 22.05 Granted as a result of the Spin-Off 1,222 11.78 Exercised (2 ) 8.35 Forfeited/Expired (721 ) 27.24 Outstanding at December 31, 2016 2,262 $ 10.82 Options Exercisable at December 31, 2016 2,262 $ 10.82 Restricted Stock In 2016 , 2015 , and 2014 , the Company issued 234,965 , 165,922 , and 137,591 shares of restricted stock to employees, which vest ratably over three years from the issuance date. In 2016 , 2015 , and 2014 , the Company also issued 72,771 , 78,985 , and 55,293 shares of stock to independent members of the board of directors which vested immediately on the issuance date. All shares of restricted stock receive dividends and have voting rights during the vesting period. 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. Compensation expense related to restricted stock was $1.6 million , $1.5 million , and $1.8 million in 2016 , 2015 , and 2014 , respectively. As of December 31, 2016 , the Company had recorded $1.9 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 fair value of the restricted stock which vested during 2016 was $1.2 million . The following table summarizes restricted stock activity for the years ended December 31, 2016 , 2015 , and 2014 : Number of Shares (000s) Weighted-Average Grant Date Fair Value Non-vested restricted stock at December 31, 2013 450 $ 8.00 Granted 138 10.75 Vested (236 ) 8.00 Forfeited (10 ) 9.48 Non-vested restricted stock at December 31, 2014 342 9.08 Granted 166 11.06 Vested (210 ) 8.41 Forfeited (5 ) 10.68 Non-vested restricted stock at December 31, 2015 293 10.65 Granted 235 8.62 Granted as a result of the Spin-Off 114 7.57 Vested (141 ) 8.54 Forfeited (30 ) 9.77 Non-vested restricted stock at December 31, 2016 471 $ 7.57 Restricted Stock Units During 2016 , 2015 , and 2014 , the Company awarded two types of performance-based RSUs to key employees: one 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 "TSR RSUs") and the other based on the ratio of cumulative funds from operations per share to targeted cumulative funds from operations per share (the “FFO RSUs”). The performance period for these awards is three years and the ultimate payout of these awards can range from 0% to 200% of the targeted number of units depending on the achievement of the performance metrics described above. Both of these RSUs are to be settled in cash with payment dependent upon the attainment of required service, market, and performance criteria. The Company expenses an estimate of the fair value of the TSR RSUs over the performance period using a quarterly Monte Carlo valuation. The Company expenses the FFO RSUs 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. Dividend equivalents on the TSR RSUs and FFO RSUs will also be paid based upon the percentage vested. The targeted number of performance-based RSUs outstanding at December 31, 2016 are 396,872 , 299,821 , and 204,690 related to the 2016 , 2015 , and 2014 grants, respectively. In 2012, the Company also issued 281,532 performance-based RSUs to the chief executive officer. The payout of these awards could have ranged from 0% to 150% of the targeted number of units depending on the total stockholder return of the Company, as defined, as compared to that of a peer group of companies through 2016. This award was expensed using a quarterly Monte Carlo valuation over the vesting period until the fourth quarter of 2016, when it was adjusted to the actual amount paid in 2017. The following table summarizes the performance-based RSU activity as of December 31, 2016 , 2015 , and 2014 (in thousands): Outstanding at December 31, 2013 755 Granted 205 Vested (150 ) Forfeited (14 ) Outstanding at December 31, 2014 796 Granted 244 Vested (191 ) Forfeited (6 ) Outstanding at December 31, 2015 843 Granted 312 Granted as a result of the Spin-Off 308 Vested (160 ) Forfeited (30 ) Outstanding at December 31, 2016 1,273 In 2016, the Company granted 28,938 time-vested RSUs to a key employee. The value of each unit is equal to the fair market value of one share of common stock. The vesting period for this award is three years. These RSUs are to be settled in cash with payment dependent upon the attainment of the required service criteria. The Company estimates future expense for all types of RSUs outstanding at December 31, 2016 to be $3.2 million (using stock prices and estimated target percentages as of December 31, 2016 ), which will be recognized over a weighted-average period of 0.9 years. During 2016 , total cash paid for all types of RSUs and related dividend payments was $1.6 million . During 2016 , 2015 , and 2014 , $6.4 million , $67,000 , and $5.4 million , respectively, was recognized as compensation expense related to RSUs for employees and directors.

CTRS recorded no income tax expense in 2016 or 2015 and CREC recorded a $20,000 income tax benefit in 2014. The net income tax benefit differs from the amount computed by applying the statutory federal income tax rate to CTRS' income before taxes for the year ended December 31, 2016 , and to CREC’s income before taxes for the years ended 2015 and 2014 as follows ($ in thousands): 2016 2015 2014 Amount Rate Amount Rate Amount Rate Federal income tax benefit (expense) $ (1,159 ) (35 )% $ 778 35 % $ (1,124 ) (35 )% State income tax benefit (expense), net of federal income tax effect (132 ) (4 )% 90 4 % (125 ) (4 )% Valuation allowance 1,282 39 % (833 ) (37 )% 1,644 50 % State deferred tax adjustment 9 — % (35 ) (2 )% (375 ) (11 )% Benefit applicable to income (loss) from continuing operations $ — — % $ — — % $ 20 — % On December 31, 2014, CREC merged into Cousins and Cousins contributed some of the assets and contracts that were previously owned by CREC to CTRS, a newly formed taxable REIT subsidiary of Cousins. Cousins retained many of CREC's tax benefits, including the significant portion of CREC's Federal and state tax carryforwards. Some of CREC's tax benefits were assumed by CTRS upon the contributions Cousins made to CTRS immediately following CREC's merger into Cousins. The tax effect of significant temporary differences representing deferred tax assets and liabilities of CTRS as of December 31, 2016 and 2015 are as follows (in thousands): 2016 2015 Income from unconsolidated joint ventures $ (188 ) $ 928 Federal and state tax carryforwards 514 680 Total deferred tax assets 326 1,608 Valuation allowance (326 ) (1,608 ) Net deferred tax asset $ — $ — A valuation allowance is required to be recorded against deferred tax assets if, based on the available evidence, it is more likely than not that such assets will not be realized. When assessing the need for a valuation allowance, appropriate consideration should be given to all positive and negative evidence related to this realization. This evidence includes, among other things, the existence of current and recent cumulative losses, forecasts of future profitability, the length of statutory carryforward periods, the Company’s history with loss carryforwards and available tax planning strategies. As of December 31, 2016 and 2015 the deferred tax asset of CTRS equaled $326,000 and $1.6 million , respectively, with a valuation allowance placed against the full amount of each. The conclusion that a valuation allowance should be recorded as of December 31, 2016 and 2015 was based the lack of evidence that CTRS, could generate future taxable income to realize the benefit of the deferred tax assets.

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, Mixed-Use, and Other. The segments by geographical region are: Atlanta, Austin, Charlotte, Orlando, Tampa, Phoenix, and Other. 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 product 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 expenses 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.

Significant Accounting Polici27

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
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, 2016 , there were no items of other comprehensive income. Therefore, no presentation of comprehensive income is required. 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. At December 31, 2016, the Company had a joint venture with Callaway Gardens Resort, Inc. (“Callaway”) for the development of residential lots, which was funded fully through Company contributions. Callaway had the right to receive returns, but no obligation to fund any costs or absorb any losses. The Company was the sole decision maker for the venture and the development manager. The Company determined that the joint venture with Callaway was a VIE, and the Company was the primary beneficiary. Therefore, the Company consolidated this joint venture.
Recently Issued Accounting Standards	Recently Issued Accounting Standards : In 2015, the FASB issued ASC 2015-02 "Consolidation (Topic 810): Amendments to the Consolidation Analysis." All legal entities are subject to reevaluation under the revised consolidation model. The amendment modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities or voting interest entities. It also eliminates the presumption that a general partner should consolidate a limited partnership. The guidance is effective for public entities with periods beginning after December 15, 2015 with early adoption permitted. The Company adopted this guidance effective January 1, 2016, and it did not have material impact on the consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting." Under this ASU, the additional paid-in capital pool is eliminated, and an entity recognizes all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement. This ASU also eliminated the requirement to defer recognition of an excess tax benefit until all benefits are realized through a reduction to taxes payable. This ASU also changes the treatment of excess tax benefits as operating cash flows in the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016 with early adoption permitted. The Company expects to adopt this guidance effective January 1, 2017, and is currently assessing the potential impact of adopting the new guidance. In February 2016, the Financial Accounting Standards Board issued ASU 2016-02, "Leases," which amends the existing standards for lease accounting by requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting and reporting. The new standard will require lessees to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months and classify such leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method (finance leases) or on a straight-line basis over the term of the lease (operating leases). Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. ASU 2016-02 supersedes previous leasing standards. The guidance is effective for the fiscal years beginning after December 15, 2018 with early adoption permitted. The Company expects to adopt this guidance effective January 1, 2019, and is currently assessing the potential impact of adopting the new guidance. The Company expects to adopt this guidance using the " modified retrospective" method effective January 1, 2019. In the first quarter of 2016, the Company adopted ASU 2015-03, "Simplifying the Presentation of Debt Costs" ("ASU 2015-03"). In accordance with ASU 2015-03, the Company began recording deferred financing costs related to its mortgage notes payable as a reduction in the carrying amount of its notes payable on the consolidated balance sheets. The Company reclassified $2.5 million in deferred financing costs from other assets to notes payable in its December 31, 2015 consolidated balance sheet to conform to the current period's presentation. Deferred financing costs related to the Company’s unsecured revolving credit facility continue to be included in other assets within the Company’s balance sheets in accordance with ASU 2015-15 "Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements." In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers." Under the new guidance, companies will recognize revenue when the seller satisfies a performance obligation, which would be when the buyer takes control of the good or service. This new guidance could result in different amounts of revenue being recognized and could result in revenue being recognized in different reporting periods than under the current guidance. The new guidance specifically excludes revenue associated with lease contracts. ASU 2015-14, "Revenue from Contracts with Customers," was subsequently issued modifying the effective date to periods beginning after December 15, 2017, with early adoption permitted for periods beginning after December 15, 2016. The standard allows for either "full retrospective" adoption, meaning the standard is applied to all of the periods presented, or "modified retrospective" adoption, meaning the standard is applied only to the most recent period presented in the financial statements. The Company is currently assessing this guidance for future implementation and potential impact of adoption. The Company expects to adopt this guidance using the "modified retrospective" method effective January 1, 2018. In August 2014, the FASB issued ASU 205-40, "Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern," which requires management of all entities to evaluate whether there are conditions and events that raise substantial doubt about the entity's ability to continue as a going concern within one year after the financial statements are issued. The Company adopted ASU 205-40 as of December 31, 2016. In January 2017, the FASB issued ASU 2017-01, "Clarifying the Definition of a Business," which provides a more narrow definition of a business to be used in determining the accounting treatment of an acquisition. As a result, many acquisitions that previously qualified as business combinations will be treated as asset acquisitions. For asset acquisitions, acquisition costs may be capitalized, and the purchase price may be allocated on a relative fair value basis. ASU 2017-01 is effective prospectively for the Company on January 1, 2018, with early adoption permitted. The Company expects that most of its future acquisitions will qualify as asset acquisitions. Certain prior year amounts have been reclassified to conform with current year presentation on the consolidated statements of operations and the consolidated statements of equity. Separation expenses on the consolidated statements of operations have been reclassified from general and administrative expenses to other expenses. On the consolidated statements of equity, all components of common stock issued pursuant to stock-based compensation are aggregated into one line item. These changes do not affect the previously reported total costs and expenses in the consolidated statements of operations or the total equity in the consolidated statements of equity for any period.
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 from the date a project is substantially complete to the earlier of (1) the date on which the project achieves 90% economic occupancy or (2) one year after it is substantially complete. The Company capitalizes direct leasing costs related to leases that are probable of being executed. These costs include commissions paid to outside brokers, legal costs incurred to negotiate and document a lease agreement, and internal costs that are based on time spent by leasing personnel on successful leases. The Company allocates these costs to individual tenant leases and amortizes them over the related lease term. Depreciation and Amortization: Real estate assets are stated at depreciated cost less impairment losses, if any. Buildings are depreciated over their estimated useful lives, which range generally from 24 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 to five years. Tenant improvements, leasing costs and leasehold improvements are amortized over the term of the applicable leases or the estimated useful life of the assets, whichever is shorter. The Company accelerates the depreciation of tenant assets if it estimates that the lease term will end prior to the termination date. This acceleration may occur if a tenant files for 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.
Impairment	Impairment: For real estate assets that are considered to be held for sale according to accounting guidance or those that are distributed to stockholders in a spin-off, the Company records impairment losses if the fair value of the asset or disposal group net of estimated selling costs is less than the carrying amount. For those long-lived assets that are held and used according to accounting guidance, management reviews each asset for the existence of any indicators of impairment. If indicators of impairment are present, the Company calculates the expected undiscounted future cash flows to be derived from such assets. If the undiscounted cash flows are less than the carrying amount of the asset, the Company reduces the asset to its fair value and records an impairment loss.
Acquisition of Real Estate Assets	Acquisition of Real Estate Assets: The Company records the acquired tangible and intangible assets and assumed liabilities of operating property acquisitions 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 in-place lease is based upon the present value (calculated using a market discount rate) of the difference between (i) the contractual rents to be paid pursuant to the lease over its remaining term and (ii) 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.
Discontinued Operations	Discontinued Operations: Beginning in the second quarter 2014, only assets held for sale or disposals representing strategic shifts in operations are reflected in discontinued operations. Prior to 2014, the Company classified the results of operations of all properties that were sold or otherwise qualified as held for sale as discontinued operations if the property's operations were expected to be eliminated from ongoing operations and the Company would not have any significant continuing involvement in the operations of the property after the sale. During 2015, there were no held for sale assets or disposals that represented a strategic shift in operations. During 2016, the Company spun-off the combined operations of the Company's and Parkway's Houston assets into a separate public company. The Company considered this disposition to be a strategic shift in operations and reclassified the historical operations of its Houston business into discontinued operations on the consolidated statements of operations. The Company ceases depreciation of a property when it is categorized as held for sale.
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 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	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, 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 into shares of cash or common stock of the Company in 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. Certain of these 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 2016 , 2015 , and 2014 , the Company recognized $90.2 million , $93.3 million , and $86.0 million , respectively, in revenues, including discontinued operations, from tenants related to operating expenses. 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. Fee Income: The Company recognizes development, management and leasing fees when earned. The Company recognizes development and leasing fees received from 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 the investment in unconsolidated joint ventures asset when fees are paid to the Company by a joint venture in which the Company has an ownership interest. See note 6 for more information related to fee income recognized from unconsolidated joint ventures. Gain on Sale of Investment Properties : The Company recognizes a gain on sale of investment property when the sale of a property is consummated, the buyer’s initial and continuing investment is adequate to demonstrate commitment to pay, any receivable obtained is not subject to future subordination, the usual risks and rewards of ownership are transferred, and the Company has no substantial continuing involvement with the property. If the Company has a commitment to the buyer and that commitment is a specific dollar amount, this commitment is accrued and the gain on sale that the Company recognizes is reduced. If the Company has a construction commitment to the buyer, management makes an estimate of this commitment, defers a portion of the profit from the sale, and recognizes the deferred profit as or when the commitment is fulfilled.
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.
Income Taxes	Income Taxes Cousins has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). To qualify as a REIT, Cousins 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 Cousins’ REIT status. As a REIT, Cousins generally will not be subject to federal income tax at the corporate level on the taxable income it distributes to its stockholders. If Cousins fails to qualify as a REIT in any taxable year, it will be subject to federal income taxes at regular corporate rates (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years. Cousins 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-Based Compensation	Stock-Based Compensation The Company has several types of stock-based compensation plans. These plans are described in note 13, as are the accounting policies by type of award. The Company recognizes compensation expense, net of forfeitures, arising from share-based payment arrangements granted to employees and directors in general and administrative expense in the statements of operations over the related awards’ vesting period, which may be accelerated under the Company’s retirement feature.
Earnings per Share (EPS)	Earnings per Share (“EPS”) 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 the outside units in CPLP were converted into the Company's common stock and stock options (or any other contracts to issue common stock) were exercised and resulted in additional common shares outstanding, calculated using the treasury stock method. The numerator is reduced for the effect of preferred dividends in both the basic and diluted net income per share calculations. Stock options are dilutive when the average market price of the Company’s stock during the period exceeds the option exercise price.
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents and Restricted Cash Cash and cash equivalents include 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 primarily represents amounts restricted under debt agreements for future capital expenditures or for specific future operating costs.
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, Mixed-Use, and Other. The segments by geographical region are: Atlanta, Austin, Charlotte, Orlando, Tampa, Phoenix, and Other. 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 product 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 expenses 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, interest expense, depreciation and amortization, impairments, gains/loss on sales of real estate, 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.
