Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies
	Basis of Presentation and Principles of Consolidation
	Parkway Properties, Inc. (the “Company") is a fully integrated, self-administered and self-managed real estate investment trust ("REIT") specializing in the acquisition, ownership and management of quality office and parking properties in high-growth submarkets in the Sunbelt region of the United States.  At January 1, 2015, the Company owned or had an interest in a portfolio of 51 office and parking properties located in eight states with an aggregate of approximately 17.2 million square feet (unaudited) of leasable space. The Company offers fee-based real estate services through its wholly owned subsidiaries, which in total managed and/or leased approximately 6.0 million square feet (unaudited) for third-party property owners at January 1, 2015.  Unless otherwise indicated, all references to square feet represent net rentable area.
	The Company is the sole general partner of Parkway Properties LP, (the "Operating Partnership" or "Parkway LP") and as of December 31, 2014, owned a 95.5% interest in the Operating Partnership. The remaining 4.5% interest consists of common units of limited partnership interest issued by the Operating Partnership to limited partners in exchange for contributions of properties to the Operating Partnership. As the sole general partner of the Operating Partnership, the Company has full and complete authority over the Operating Partnership’s day-to-day operations and management.
	The accompanying financial statements are prepared following U.S. generally accepted accounting principles ("GAAP") and the requirements of the Securities and Exchange Commission (the "SEC").
	The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries and joint ventures in which the Company has a controlling interest. The other partners' equity interests in the consolidated joint ventures are reflected as noncontrolling interests in the consolidated financial statements. The Company also consolidates subsidiaries where the entity is a variable interest entity ("VIE") and it is the primary beneficiary and has the power to direct the activities of the VIE and has the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. At December 31, 2014 and 2013, the Company did not have any VIEs that required consolidation. All significant intercompany transactions and accounts have been eliminated in the accompanying financial statements.
	The Company consolidates certain joint ventures where it exercises control over major operating and management decisions, or where the Company is the sole general partner and the limited partners do not possess kick-out rights or other substantive participating rights. The equity method of accounting is used for those joint ventures that do not meet the criteria for consolidation and where the Company does not control these joint ventures, but exercises significant influence. The cost method of accounting is used for investments in which the Company does not have significant influence. The investments are reviewed for impairment when indicators of impairment exist.
	Business
	The Company's operations are exclusively in the real estate industry, principally the operation, leasing, acquisition, development and ownership of office buildings.
	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, the 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. Although the Company believes the assumptions and estimates made are reasonable and appropriate, as discussed in the applicable sections throughout these consolidated financial statements, different assumptions and estimates could materially impact reported results. The current economic environment has increased the degree of uncertainty inherent in these estimates and assumptions; therefore, changes in market conditions could impact the Company's future operating results. The Company's most significant estimates relate to impairments on real estate and other assets and purchase price allocations.
	Real Estate Properties
	Real estate properties are carried at cost less accumulated depreciation. Cost includes the carrying amount of the Company's investment plus any additional consideration paid, liabilities assumed, and improvements made subsequent to acquisition. Depreciation of buildings and building improvements is computed using the straight-line method over the estimated useful lives of the assets. Depreciation of tenant improvements, including personal property, is computed using the straight-line method over the lesser of useful life or the term of the lease involved. Maintenance and repair expenses are charged to expense as incurred.
	Balances of major classes of depreciable assets (in thousands) and their respective estimated useful lives are:
					December 31,
	Asset Category		Estimated Useful Life		2014		2013
	Land		Non-depreciable		$	412,578	$	278,780
	Buildings and garages		40 years		2,535,757		1,973,668
	Building improvements		7 to 40 years		52,715		78,450
	Tenant improvements		Lesser of useful life or term of lease		332,850		217,138
					$	3,333,900	$	2,548,036
	Depreciation expense, excluding amounts recorded in discontinued operations, related to these assets of $102.2 million, $69.0 million, and $45.3 million was recognized in 2014, 2013 and 2012, respectively.
	The Company evaluates its real estate assets upon occurrence of significant adverse changes in its operations to assess whether any impairment indicators are present that affect the recovery of the carrying amount. The carrying amount includes the net book value of tangible and intangible assets and liabilities. Real estate assets are classified as held for sale or held and used. The Company classifies certain assets as held for sale based on management having the authority and intent of entering into commitments for sale transactions to close in the next twelve months. The Company considers an office and parking property as held for sale once it has executed a contract for sale, allowed the buyer to complete its due diligence review and received a substantial non-refundable deposit. Until a buyer has completed its due diligence review of the asset, necessary approvals have been received and substantive conditions to the buyer's obligation to perform have been satisfied, the Company does not consider a sale to be probable. When the Company identifies an asset as held for sale, it estimates the net realizable value of such asset and discontinues recording depreciation on the asset. The Company records assets held for sale at the lower of carrying amount or fair value less cost to sell. If the fair value of the asset net of estimated selling costs is less than the carrying amount, the Company records an impairment loss. With respect to assets classified as held and used, the Company recognizes an impairment loss if the carrying amount is not recoverable and exceeds the sum of undiscounted future cash flows expected to result from the use and eventual disposition of the asset. Upon impairment, the Company recognizes an impairment loss to reduce the carrying value of the real estate asset to the estimate of its fair value. The cash flow and fair value estimates are based on assumptions about employing the asset for its remaining useful life. Factors considered in projecting future cash flows include, but are not limited to: existing leases, future leasing and terminations, market rental rates, capital improvements, tenant improvements, leasing commissions, inflation, discount rates, capitalization rates, and other known variables. This market information is considered a Level 3 input as defined by Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 820, "Fair Value Measurements and Disclosures," ("ASC 820").
	The Company recognizes gains on sales of real estate at times and in amounts determined in accordance with the accounting guidance for sales of real estate. The guidance takes into account the terms of the transaction and any continuing involvement, including in the form of management, leasing of space or financial assistance associated with the properties. If the sales criteria for the full accrual method are not met, then the Company defers gain recognition and accounts for the transaction by applying the deposit, finance, installment or cost recovery methods, as appropriate.
	During the year ended December 31, 2014, the Company recognized an impairment loss on real estate of $11.7 million in connection with Raymond James Tower in Memphis, Tennessee. During the year ended December 31, 2013, the Company recognized an impairment loss on real estate of $10.2 million in connection with Waterstone and Meridian in Atlanta, Georgia and Mesa Corporate Center in Phoenix, Arizona. During the year ended December 31, 2012, the Company recognized an impairment loss on real estate of $9.2 million in connection with two assets in Jackson, Mississippi and Columbia, South Carolina.
	At December 31, 2014, the Company classified Raymond James Tower in Memphis, Tennessee and Honeywell in Houston, Texas as assets held for sale. At December 31, 2013, the Company classified Mesa Corporate Center in Phoenix, Arizona and the Woodbranch Building in Houston, Texas as held for sale.
	Condominium Units
	The Company also consolidates its Murano residential condominium project which it controls. The Company's unaffiliated partner's interest is reflected on its consolidated balance sheets under the "Noncontrolling Interests" caption. The Company's partner has a stated ownership interest of 27%. Net proceeds from the project will be distributed, to the extent available, based on an order of preferences described in the partnership agreement. The Company may receive distributions, if any, in excess of its stated 73% ownership interest if certain return thresholds are met.
	Purchase Price Allocation
	The Company allocates the purchase price of real estate to tangible and intangible assets and liabilities based on fair values. Tangible assets consist of land, building, garage, building improvements and tenant improvements. Intangible assets and liabilities consist of the value of above and below market leases, lease costs, the value of in-place leases, and any value attributable to above or below market debt assumed with the acquisition.
	The Company may engage independent third-party appraisers to perform the valuations used to determine the fair value of these identifiable tangible and intangible assets. These valuations and appraisals use commonly employed valuation techniques, such as discounted cash flow analyses. Factors considered in these analyses include an estimate of costs during hypothetical expected lease-up periods considering current market conditions and costs to execute similar leases. The Company also considers information obtained about each property as a result of its pre-acquisition due diligence, marketing and leasing activities in estimating the fair value of the tangible and intangible assets acquired. The Company includes real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods depending on specific local market conditions and depending on the type of property acquired. Additionally, the Company estimates costs to execute similar leases including leasing commissions, legal and other related expenses to the extent that such costs are not already incurred in connection with a new lease origination as part of the transaction.
	The fair value of above or below market in-place lease values is the present value of the difference between the contractual amount to be paid pursuant to the in-place lease and the estimated current market lease rate expected over the remaining non-cancelable life of the lease. The capitalized above market lease values are amortized as a reduction of rental income over the remaining term of the respective leases. The capitalized below market lease values are amortized as an increase to rental income over the remaining term of the respective leases. Total amortization for above and below market leases, excluding amounts classified as discontinued operations, was a net increase (reduction) of rental income of $13.7 million, $(2.2) million and $(5.0) million for the years ended December 31, 2014, 2013 and 2012, respectively.
	As of December 31, 2014, the remaining amortization of net (above) and below market leases is projected as a net increase (decrease) to rental income as follows (in thousands):
		Amount
	2015	$	14,343
	2016	4,448
	2017	3,052
	2018	1,845
	2019	2,844
	Thereafter	(6,456		)
	Total	$	20,076
	The fair value of in-place leases is the present value associated with re-leasing the in-place lease as if the property was vacant. Factors to be considered include estimates of costs during hypothetical expected lease-up periods considering current market conditions and costs to execute similar leases. In estimating costs, the Company includes estimates of lost rentals at market rates during the expected lease-up periods. The value of at market in-place leases is amortized as a lease cost amortization expense over the expected life of the lease. Total amortization expense for the value of in-place leases, excluding amounts classified as discontinued operations, was $51.8 million, $26.9 million, and $15.0 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	As of December 31, 2014, the remaining amortization expense for the value of in-place leases is projected as follows (in thousands):
		Amount
	2015	$	42,602
	2016	26,390
	2017	18,097
	2018	11,880
	2019	9,006
	Thereafter	21,254
	Total	$	129,229
	A separate component of the fair value of in-place leases is identified for the lease costs. The fair value of lease costs represents the estimated commissions and legal fees paid in connection with the current leases in place. Lease costs are amortized over the non-cancelable terms of the respective leases as lease cost amortization expense.
	In no event does the amortization period for intangible assets exceed the remaining depreciable life of the building. Should a customer terminate its lease, the unamortized portion of the tenant improvement, in-place lease value, lease cost and customer relationship intangibles would be charged to expense. Additionally, the unamortized portion of above market in-place leases would be recorded as a reduction to rental income and the below market in-place lease value would be recorded as an increase to rental income.
	The Company calculates the fair value of mortgage notes payable by discounting the remaining contractual cash flows on each instrument at the current market rate for these borrowings.
	Capitalization of Costs
	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 certain costs of leasing personnel in connection with the completion of leasing arrangements.
	Net Income (Loss) Per Common Share
	Basic earnings per share ("EPS") is computed by dividing income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding for the year. In arriving at net income (loss) attributable to common stockholders, preferred stock dividends are deducted. Diluted EPS reflects the potential dilution that could occur if share equivalents such as employee stock options, restricted shares and deferred incentive share units were exercised or converted into common stock that then shared in the earnings of the Company.
	Allowance for Doubtful Accounts
	Accounts receivable are reduced by an allowance for amounts that the Company estimates to be uncollectible. The receivable balance is comprised primarily of rent and expense reimbursement income due from the customers. Management evaluates the adequacy of the allowance for doubtful accounts considering such factors as the credit quality of the customers, delinquency of payment, historical trends and current economic conditions. The Company provides an allowance for doubtful accounts for customer balances that are over 90 days past due and for specific customer receivables for which collection is considered doubtful.
	Cash Equivalents
	The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.
	Restricted Cash
	Restricted cash, which is included in receivables and other assets, primarily consists of security deposits held on behalf of the Company's tenants as well as capital improvements and real estate tax escrows required under certain loan agreements. There are restrictions on the Company's ability to withdraw these funds other than for their specified usage.
Noncontrolling Interest
A noncontrolling interest in a subsidiary is in most cases an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements and separate from the parent company's equity. In addition, consolidated net income is required to be reported at amounts that include the amounts attributable to both the parent and the noncontrolling interest and the amount of consolidated net income attributable to the parent and the noncontrolling interest are required to be disclosed on the face of the consolidated statements of operations and comprehensive income.
Revenue Recognition
Revenue from real estate rentals is recognized on a straight-line basis over the terms of the respective leases. The cumulative difference between lease revenue recognized under this method and contractual lease payment terms is recorded as straight-line rent receivable on the accompanying balance sheets. The straight-line rent adjustment increased revenue by $21.0 million, $14.6 million and $14.9 million in 2014, 2013, and 2012, respectively.
When the Company is the owner of the tenant improvements, the leased space is ready for its intended use when the tenant improvements are substantially completed, at which point revenue recognition begins. In limited instances, when the tenant is the owner of the customer improvements, straight-line rent is recognized when the tenant takes possession of the unimproved space.
The leases also typically provide for tenant reimbursement of a portion of common area maintenance, real estate taxes and other operating expenses.  Property operating cost recoveries from customers ("expense reimbursements") are recognized as revenue in the period in which the expenses are incurred. The computation of expense reimbursements is dependent on the provisions of individual customer leases. Most customers make monthly fixed payments of estimated expense reimbursements. The Company makes adjustments, positive or negative, to expense reimbursement income quarterly to adjust the recorded amounts to the Company's best estimate of the final property operating costs based on the most recent annual estimate. After the end of the calendar year, the Company computes each customer's final expense reimbursements and issues a bill or credit for the difference between the actual amount and the amounts billed monthly during the year. Differences between actual billed amounts and accrued amounts are considered immaterial.
Management company income represents market-based fees earned from providing management, construction, leasing, brokerage and acquisition services to unconsolidated joint ventures, related parties, and third parties. Management fee income is computed and recorded monthly in accordance with the terms set forth in the management service agreements. Leasing and brokerage commissions, as well as salary and administrative fees, are recognized pursuant to the terms of the agreements at the time underlying leases are signed, which is the point at which the earnings process is complete and collection of the fees is reasonably assured. Fees relating to the purchase or sale of property are recognized when the earnings process is complete and collection of the fees is reasonably assured, which usually occurs at closing. All fees on Company-owned properties and consolidated joint ventures are eliminated in consolidation. The Company recognizes its share of fees earned from unconsolidated joint ventures in management company income.
The Company has one high-rise condominium project. Under the provisions of FASB ASC 360-20, "Property, Plant and Equipment" subsection "Real Estate and Sales," revenue and costs for projects are recognized when all parties are bound by the terms of the contract, all consideration has been exchanged, any permanent financing for which the seller is responsible has been arranged and all conditions precedent to closing have been performed. This results in profit from the sale of condominium units recognized at closing. Revenue is recognized on the contract price of individual units. Total estimated costs are allocated to individual units which have closed on a relative value basis.
Investment in Unconsolidated Joint Ventures
The Company accounts for its investment in unconsolidated joint ventures under the equity method of accounting as the Company exercises significant influence, but does not maintain a controlling financial interest over these entities. These investments are recorded initially at cost and subsequently adjusted for cash contributions, distributions and equity in earnings (loss) of the unconsolidated joint ventures. Equity in earnings (loss) in unconsolidated joint ventures is allocated based on ownership or economic interest in each joint venture.
The Company's investments in real estate joint ventures are reviewed for impairment periodically, and it records impairment charges when events or circumstances change indicating that a decline in the fair values below the carrying values has occurred and such decline is other-than-temporary. The ultimate realization of the investment in real estate joint ventures is dependent on a number of factors, including the performance of each investment and market conditions. No impairment charges related to the Company's investments in real estate joint ventures were recorded during the year ended December 31, 2014 or 2013.
Amortization of Debt Origination Costs and Leasing Costs
Debt origination costs are deferred and amortized using a method that approximates the effective interest method over the term of the loan. Leasing costs are deferred and amortized using the straight-line method over the term of the respective lease.
Loss on Extinguishment of Debt
When outstanding debt is extinguished, the Company records any prepayment premium and unamortized loan costs.
Derivative Financial Instruments
The Company recognizes all derivative instruments on the balance sheet at their fair value. Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive loss if a derivative is designated as part of a hedge transaction and, if it is, the type of hedge transaction. The ineffective portion of the hedge, if any, is immediately recognized in earnings.
Share-Based and Long-Term Compensation
Compensation expense, net of estimated forfeitures, for service-based awards is recognized over the expected vesting period of such awards. The total compensation expense for the long-term equity incentive awards is based upon the fair value of the shares on the grant date, adjusted for estimated forfeitures. Time-vesting restricted shares, restricted share units ("RSUs"), and deferred incentive share units are valued based on the New York Stock Exchange closing market price of the Company's common shares as of the date of grant. The grant date fair value for awards that are subject to performance-based vesting and market conditions, including profits interest units ("LTIP units"), performance-vesting RSUs, and long-term equity incentive awards, is determined using a simulation pricing model developed to specifically accommodate the unique features of the awards. The total compensation expense for stock options is estimated based on the fair value of the options as of the date of grant using the Black-Scholes model.
Income Taxes
The Company elected to be taxed as a REIT under the Internal Revenue Code, commencing with its taxable year ended December 31, 1997. To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement that it currently distribute at least 90% of its adjusted taxable income to its stockholders. It is management's current intention to adhere to these requirements and maintain the Company's REIT status, and the Company was in compliance with all REIT requirements at December 31, 2014. As a REIT, the Company generally will not be subject to corporate level federal income tax on taxable income it distributes currently 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 (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property, and to federal income and excise taxes on its undistributed taxable income. In addition, taxable income from non-REIT activities managed through taxable REIT subsidiaries (collectively, the "TRS") is subject to federal, state and local income taxes.
Restructuring Charges
Restructuring charges reflected in general and administrative expenses in the accompanying consolidated statements of operations and comprehensive income (loss) relate primarily to one-time termination benefits. The Company recognizes these severance and other charges when the requirements of FASB ASC 420, "Exit or Disposal Cost Obligations," have been met regarding a plan of termination and when communication has been made to employees.
Fair Value Measurements
Level 1 fair value inputs are quoted prices for identical assets or liabilities in active, liquid and visible markets such as stock exchanges. Level 2 fair value inputs are observable information for similar assets or liabilities in active or inactive markets, and appropriately consider counterparty creditworthiness in the valuations. Level 3 fair value inputs reflect the Company's best estimate of inputs and assumptions market participants would use in pricing an asset or liability at the measurement date. These inputs are unobservable in the market and significant to the valuation estimate.
Reclassifications
Certain reclassifications have been made in the 2013 and 2012 consolidated financial statements to conform to the 2014 classifications with no impact on previously reported net income or equity.
Recent Accounting Pronouncements
Effective January 1, 2014, the Company adopted guidance issued by FASB Accounting Standards Update ("ASU") No. 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." This update amends the criteria for reporting discontinued operations to, among other things, raise the threshold for disposals to qualify as discontinued operations, and only disposals that represent a strategic shift in operations that is material will be presented as discontinued operations. This update is effective for interim and annual reporting periods, beginning after December 15, 2014, with early adoption permitted. The Company presents 2014 property sales and will present future property sales, to the extent they do not represent a strategic shift in operations, in the continuing operations section of the consolidated statements of operations and comprehensive income (loss) with the exception of those properties previously included as held for sale at December 31, 2013. The Company's 2014 sales of the Woodbranch Building and Mesa Corporate Center are included in discontinued operations for the year ended December 31, 2014 as these properties were previously classified as held for sale at December 31, 2013. The Company's 2014 sales of the Schlumberger Building and 525 North Tryon are included in the continuing operations section of the consolidated statements of operations and comprehensive income (loss) as they were not previously classified as held for sale as of December 31, 2013 and do not qualify for inclusion in discontinued operations as they do not represent a strategic shift in the Company's operations.
In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." This update was initiated in a joint project between the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP and International Financial Reporting Standards that would: (1) remove inconsistencies and weaknesses in revenue requirements; (2) provide a more robust framework for addressing revenue issues; (3) improve comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets; (4) provide more useful information to users of financial statements through improved disclosure requirements; and (5) simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. This update is effective for interim and annual reporting periods, beginning after December 15, 2016, and early application is not permitted. 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.
In August 2014, the FASB issued ASU No. 2014-15, "Presentation of Financial Statements - Going Concern." The amendments in this update provide guidance in GAAP about management's responsibilities to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. The main provision of the amendments are for an entity's management, in connection with the preparation of financial statements, to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued. Management's evaluation should be based on relevant conditions and events that are known or reasonably knowable at the date the financial statements are issued. When management identifies conditions or events that raise substantial doubt about an entity's ability to continue as a going concern, the entity should disclose information that enables users of the financial statements to understand all of the following: (1) principal conditions or events that raised substantial doubt about the entity's ability to continue as a going concern (before consideration of management's plans); (2) management's evaluation of the significance of those conditions or events in relation to the entity's ability to meet its obligations; and (3) management's plans that alleviated substantial doubt about the entity's ability to continue as a going concern or management's plans that are intended to mitigate the conditions or events that raise substantial doubt about the entity's ability to continue as a going concern. The amendments in this update are effective for interim and annual reporting periods after December 15, 2016 and early application is permitted. The Company is currently assessing this guidance for future implementation.
In January 2015, the FASB issued ASU No. 2015-01, "Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items", (“ASU 2015-01”). ASU 2015-01 eliminates the concept of an extraordinary item from GAAP. As a result, an entity will no longer be required to segregate extraordinary items from the results of ordinary operations, to separately present an extraordinary item on its income statement, net of tax, after income from continuing operations or to disclose income taxes and earnings-per-share data applicable to an extraordinary item. However, ASU 2015-01 will still retain the presentation and disclosure guidance for items that are unusual in nature and occur infrequently. ASU 2015-01 will be effective for the Company’s fiscal year beginning January 1, 2016 and subsequent interim periods. The adoption of ASU 2015-015 is not expected to have a material effect on the Company’s consolidated financial statements.
In February 2015, the FASB issued new consolidation guidance which makes changes to both the variable interest model and the voting model.  The new standard specifically eliminates the presumption in the current voting model that a general partner controls a limited partnership or similar entity unless that presumption can be overcome.  Generally, only a single limited partner that is able to exercise substantive kick-out rights will consolidate.  The new standard will be effective for the Company beginning on January 1, 2016 and early adoption is permitted, including adoption in an interim period.  The new standard must be applied using a modified retrospective approach by recording either a cumulative-effect adjustment to equity as of the beginning of the period of adoption or retrospectively to each period presented.  The Company is currently evaluating the impact of adopting the new standard on its consolidated financial statements.

Real Estate [Abstract]
Investment in Office and Parking Properties	Investment in Office and Parking Properties
	Included in investment in office and parking properties at December 31, 2014 are 49 office and parking properties located in eight states with an aggregate of 16.5 million square feet (unaudited) of leasable space.
	The Company's acquisitions are accounted for using the acquisition method. The results of each acquired property are included in the Company's results of operations from their respective purchase dates. The impact of 2014 acquired properties on the Company's consolidated statement of operations and comprehensive income (loss) for the year ended December 31, 2014 was a net loss of $2.1 million, including $28.9 million of total revenues.
	2014 Acquisitions
	The gross purchase price, excluding closing costs and other adjustments, of office and parking properties acquired during the year ended December 31, 2014 is as follows:
	Market Location	Cost (in thousands)
	Atlanta, Georgia	$	47,000
	Austin, Texas	311,400
	Jacksonville, Florida	33,300
	Orlando, Florida	80,611
	Miami, Florida	140,495
	Tampa, Florida	249,669
		$	862,475
	On January 30, 2014, the Company completed the acquisition of the JTB Center, a complex of three office buildings located in the Deerwood submarket of Jacksonville, Florida, for a gross purchase price of $33.3 million. The JTB Center was unencumbered by secured indebtedness and financed through available cash.
	On April 10, 2014, the Company completed the acquisition of Courvoisier Centre, a complex of two office buildings located in the Brickell submarket of Miami, Florida, for a gross purchase price of $145.8 million. The acquisition was financed through available cash and borrowings under the Company's unsecured term loans.
	On April 14, 2014, the Company commenced construction of Hayden Ferry Lakeside III, a planned office development in the Tempe submarket of Phoenix, Arizona. The Operating Partnership entered into an amendment to the partnership agreement of Parkway Properties Office Fund II L.P. ("Fund II") to, among other things, authorize the Hayden Ferry Lakeside III development and authorize the general partner of Fund II to transfer an interest in the ownership of Hayden Ferry Lakeside III, a subsidiary of Fund II, to the Operating Partnership for $2.0 million. The Company now owns a 70% indirect controlling interest in Hayden Ferry Lakeside III. Costs related to planning, developing, leasing and constructing the property, including costs of development personnel working directly on projects under development, are capitalized. For the year ended December 31, 2014, development costs incurred totaled approximately $24.0 million. On July 2, 2014, Fund II closed on a construction loan secured by Hayden Ferry Lakeside III. See "Note 8—Capital and Financing Transactions—Mortgage Notes Payable" for additional details.
	On April 14, 2014, the Company completed the acquisition of One Orlando Centre, an office building located in the central business district of Orlando, Florida, for a gross purchase price of $55.1 million. The Company made an $8.0 million equity investment that will be held in lender reserve accounts to fund the leasing and repositioning of the asset. As part of the purchase price, the Company paid $1.1 million to acquire its 100% interest in the property and simultaneously with the equity investment, the existing $68.3 million first mortgage note secured by the property was restructured into a new $54.0 million first mortgage and a $15.3 million subordinated note. See "Note 8—Capital and Financing Transactions—Mortgage Notes Payable" for additional details.
	On July 3, 2014, the Company completed the acquisition of Millenia Park One, an office building located in the Millenia submarket of Orlando, Florida, for a gross purchase price of $25.5 million. The acquisition was funded using available cash and borrowings from the Company's senior unsecured revolving credit facility.
	On July 29, 2014, the Company purchased a first mortgage note in an original principal amount of $50.0 million secured by The Forum at West Paces, an office building located in the Buckhead submarket of Atlanta, Georgia. The total purchase price for the note, which was previously under special servicer oversight, was approximately $47.0 million. The note purchase was funded with borrowings under the Company's senior unsecured revolving credit facility. On August 19, 2014, the Company took ownership of The Forum at West Paces with a deed in lieu of foreclosure.

	On April 10, 2012, the Company transferred its rights, title and interest in the B participation piece (the "B piece") of a first mortgage loan secured by an office building in Dallas, Texas known as 2100 Ross. The B piece was purchased at an original cost of $6.9 million in November 2007. The B piece was originated by Wachovia Bank, N.A., a Wells Fargo Company, and had a face value of $10.0 million, a stated coupon rate of 6.1% and a scheduled maturity in May 2012. During 2011, the Company recorded a non-cash impairment loss on the mortgage loan in the amount of $9.2 million, thereby reducing its investment in the mortgage loan to zero. Under the terms of the transfer, the Company is entitled to certain payments if the transferee is successful in obtaining ownership of 2100 Ross. During the third quarter of 2012, the transferee successfully obtained ownership of 2100 Ross and as a result the Company received a $500,000 payment, which is classified as recovery of losses on a mortgage loan receivable on the Company's consolidated statements of operations and comprehensive income (loss).

	On November 5, 2013, the Company and its joint venture partner foreclosed and took ownership of 7000 Central Park, an office building located in the Central Perimeter of Atlanta, Georgia.

After giving effect to these transactions, the Company has a 40% interest in the CalSTRS joint venture and the Austin properties, with CalSTRS owning the remaining 60%.
	On November 17, 2014, the Company terminated the Austin Joint Venture.

	In 2011, as part of the Company's combination with Eola Capital, LLC ("Eola"), the Company purchased the management contracts associated with Eola's property management business. At the purchase date, the contracts were valued by an independent appraiser at $51.8 million. The value of the management contracts is based on the sum of the present value of future cash flows attributable to the management contracts, in addition to the value of tax savings as a result of the amortization of intangible assets.
	During 2012, the Company evaluated certain qualitative factors and determined that it was necessary to apply the two-step quantitative impairment test under ASU No. 2011-08, "Intangibles—Goodwill and Other (Topic 350), Testing Goodwill for Impairment." During this process the Company determined that the management contracts were impaired due to the fair value of the management contracts being estimated at $19.0 million as compared to the carrying amount of $46.1 million. As a result, the Company recorded a $42.0 million non-cash impairment loss, net of deferred tax liability, associated with the Company's investment in management contracts and goodwill.
	The Company assumed a management contract as part of the Company's merger with TPGI. At December 19, 2013, the date of the Mergers, the contract was valued by an independent appraiser at $1.8 million.
	During the year ended December 31, 2014, the Company determined that the undiscounted cash flows indicated that the carrying amounts of the Eola contracts were not expected to be recovered and, as a result, the Company recorded a $4.8 million pre-tax non-cash impairment loss related to these management contracts which resulted in the entire remaining balance of the Eola contracts being written off as of December 31, 2014.

	-1	Effective October 1, 2012, the Company executed two floating-to-fixed interest rate swaps associated with the Term Loan Facility totaling $125 million, locking LIBOR at 0.7% for five years. The loan bears interest at LIBOR plus the applicable spread which ranges between 150 to 225 basis points based on overall Company leverage. The current spread associated with the loan is 1.75% resulting in an all-in rate of 2.45%.
	-2	Effective June 12, 2013, the Company entered into a new floating-to-fixed interest rate swap associated with a New Term Loan Facility totaling $120 million, locking LIBOR at 1.6% for five years. The loan bears interest at LIBOR plus the applicable spread which ranges between 145 to 220 basis points based on overall Company leverage. The current spread associated with the loan is 1.7% resulting in an all-in rate of 3.3%.
	On June 12, 2013, the Company entered into a term loan agreement for a $120 million unsecured term loan. The unsecured term loan has a maturity date of June 11, 2018, and has an accordion feature that allows for an increase in the size of the unsecured term loan to as much as $250 million. Interest on the unsecured term loan is based on LIBOR plus an applicable margin of 145 to 200 basis points depending on overall Company leverage (with the current rate set at 145 basis points). The unsecured term loan has substantially the same operating and financial covenants as required by the Company's $215 million senior unsecured revolving credit facility. Wells Fargo Bank, National Association, acted as Administrative Agent and lender. The Company also executed a floating-to-fixed interest rate swap totaling $120.0 million, locking LIBOR at 1.6% for five years and resulting in an effective current interest rate of 3.3%. The unsecured term loan had an outstanding balance of $120.0 million at December 31, 2013.
	Effective April 1, 2014, the Company entered into an Amended, Restated and Consolidated Credit Agreement (the "Amended Agreement") which provides for a $250.0 million senior unsecured revolving credit facility, a $250.0 million five-year unsecured term loan and a $100.0 million seven-year unsecured term loan. The Amended Agreement amended, restated and consolidated the agreements governing the Company's prior $215.0 million senior unsecured revolving credit facility, $125.0 million unsecured term loan and $120.0 million unsecured term loan. The maturity date of the senior unsecured revolving credit facility was extended to March 30, 2018, with an additional one-year extension option, and the $250.0 million five-year unsecured term loan and $100.0 million seven-year unsecured term loan have maturity dates of March 29, 2019 and March 31, 2021, respectively.
	The senior unsecured revolving credit facility bears interest at LIBOR plus an applicable margin which ranges from 1.40% to 2.00% based on the Company's overall leverage, and is currently 1.40% resulting in an all-in rate of 1.56%. The $250.0 million five-year unsecured term loan bears interest at LIBOR plus an applicable margin which ranges from 1.35% to 1.90% based on the Company's overall leverage, and is currently 1.35% resulting in a weighted average all-in rate of 2.51%, after giving effect to the floating-to-fixed-rate interest rate swaps. The $100.0 million seven-year unsecured term loan bears interest at LIBOR plus an applicable margin which ranges from 1.75% to 2.30% based on the Company's overall leverage, and is currently 1.75%, resulting in an all-in rate of 4.31%, after accounting for the floating-to-fixed-rate interest rate swap. For a discussion of interest rate swaps entered into in connection with the Company's unsecured term loans and senior unsecured revolving credit facility, see " —Interest Rate Swaps."
	The $100.0 million seven-year unsecured term loan tranche had a delayed-draw feature which allowed the Company to draw all or a portion of the $100.0 million commitment in not more than two draws over a 12-month period. The Company drew the full amount on April 8, 2014 and simultaneously repaid in full the first mortgage debt secured by the Bank of America Center in Orlando, Florida, which had an outstanding balance of $33.9 million. The Company recognized a loss on extinguishment of debt of $339,000 on the repayment of the Bank of America Center mortgage.
	Additionally, effective April 1, 2014, the Company amended its $10.0 million unsecured working capital credit facility under terms and conditions similar to the Amended Agreement.

On February 21, 2013, the Company obtained an $80.0 million first mortgage loan secured by Phoenix Tower, an office property located in the Greenway Plaza submarket of Houston, Texas. The mortgage loan bears interest at a fixed rate of 3.9% and matures on March 1, 2023. Payments of interest only are due on the loan for two years, after which the principal amount of the loan begins amortizing over a 25-year period until maturity. The loan is pre-payable after March 1, 2015, but any such prepayment is subject to a yield maintenance premium. The agreement governing the mortgage loan contains customary rights of the lender to accelerate the loan upon, among other things, a payment default or if certain representations and warranties made by the borrower are untrue.
On March 7, 2013, simultaneous with the purchase of the Deerwood Portfolio, the Company obtained an $84.5 million first mortgage loan, which is secured by the office properties in the portfolio. The mortgage loan bears interest at a fixed rate of 3.9% and matures on April 1, 2023. Payments of interest only are due on the loan for three years, after which the principal amount of the loan begins amortizing over a 30-year period until maturity. The loan is pre-payable after May 1, 2015, but any such prepayment is subject to a yield maintenance premium. The agreement governing the mortgage loan contains customary rights of the lender to accelerate the loan upon, among other things, a payment default or if certain representations and warranties made by the borrower are untrue.
On May 31, 2013, the Company modified the existing $22.5 million first mortgage loan secured by Corporate Center IV, an office property located in the Westshore submarket of Tampa, Florida. The modified first mortgage loan has a principal balance of $36.0 million, a weighted average fixed interest rate of 4.6%, an initial 24 months interest only period and a maturity date of April 8, 2019. In conjunction with the modification, the Company executed a floating-to-fixed interest rate swap fixing the interest rate on the additional $13.5 million in loan proceeds at 3.3%.
On June 28, 2013, the Company modified the existing mortgage loan secured by Hayden Ferry II, an office property located in the Tempe submarket of Phoenix, Arizona. The loan modification eliminates quarterly principal payments of $625,000.  As a result of the modification, loan payments are now interest-only through February 2015.  The mortgage loan bears interest at LIBOR plus an applicable spread which ranges from 250 to 350 basis points. The Company entered into a floating-to-fixed interest rate swap that fixed LIBOR on the original loan at 1.5% through January 2018 and resulted in an all-in interest rate of 4.7% on December 31, 2013. Effective August 1, 2013, the Company entered into a second floating-to-fixed interest rate swap which fixes LIBOR at 1.7% through January 2018 on the additional notional amount of $625,000 associated with the loan modification, resulting in an all-in interest rate of 4.9%.  This loan is cross-defaulted with Hayden Ferry I, IV and V.
On December 6, 2013, in connection with the purchase of Lincoln Place, the Company assumed a mortgage loan with a balance of $49.3 million at December 31, 2013, with a fixed interest rate of 5.9% and a maturity date of June 11, 2016.
On December 19, 2013, in connection with the Mergers, the Company assumed $321.0 million of existing first mortgage loans that are secured by the properties. The mortgage loan for CityWestPlace buildings I and II carries a balance of $117.7 million at December 31, 2013, with a fixed interest rate of 6.2% and a maturity date of July 6, 2016. The mortgage loan for CityWestPlace buildings III and IV carries a balance of $93.4 million at December 31, 2013, with a fixed interest rate of 5.0% and a maturity date of March 5, 2020. The mortgage loan for San Felipe Plaza carries a balance $110.0 million at December 31, 2013, with a fixed interest rate of 4.8% and a maturity date of December 1, 2018.
On April 8, 2014, the Company repaid the first mortgage debt secured by Bank of America Center and terminated the related $33.9 million floating-to-fixed interest rate swap. The terminated $33.9 million swap had a liability value of $1.9 million which was rolled into the pricing set for the new $100.0 million swap.
On April 14, 2014, the Company purchased One Orlando Centre in Orlando, Florida, and simultaneously restructured the existing first mortgage loan secured by the property. The existing $68.3 million first mortgage note was restructured into a new $54.0 million first mortgage note and a $15.3 million subordinated note. Upon the sale or recapitalization of the property, proceeds are to be distributed first to the lender up to the amount of outstanding principal of the first mortgage note; second, to the Company up to its equity investment; third, to the Company until it receives a 12% annual return on its equity investment; fourth, 60% to the Company and 40% to the lender until the subordinated note is repaid in full; and fifth, to the Company at 100%. At the acquisition date, and as of December 31, 2014, the fair value of the subordinated note was zero.
On July 2, 2014, Fund II closed on a construction loan secured by the Hayden Ferry Lakeside III development in the Tempe submarket of Phoenix, Arizona, for $43.0 million, or 62.5% of the total estimated cost of the development, which will be funded subsequent to Fund II's and the Company's equity investment in the development. The loan is initially a 35% recourse loan to Fund II that will be reduced to non-recourse upon stabilization of the property. The loan is cross-collateralized with Fund II's Hayden Ferry Lakeside I, Hayden Ferry Lakeside II, Hayden Ferry Lakeside IV and the adjacent parking garage. The loan matures on July 25, 2018, is interest-only through maturity, and has an interest rate of one-month LIBOR plus 1.80% which decreases to 1.60% upon stabilization. As of December 31, 2014, the balance of the construction loan payable was approximately $481,000.
On November 17, 2014, the Company terminated the Austin Joint Venture. As part of the agreement, the Company acquired CalSTRS' 60% interest in One Congress Plaza and San Jacinto Center, resulting in 100% ownership of these two assets. As a result the Company assumed a mortgage loan with a balance of $128.0 million at December 31, 2014, with a fixed interest rate of 3.2% and a maturity date of June 11, 2017 for One Congress Plaza, and assumed a mortgage loan with a balance of $101.0 million at December 31, 2014, with a fixed interest rate of 3.2% and a maturity date of June 11, 2017 for San Jacinto Center.
On December 31, 2014, the Company extinguished the mortgage loan associated with Raymond James Tower in Memphis, Tennessee with a principal balance of $7.9 million. The Company incurred a loss on extinguishment of debt of approximately $2.1 million as part of the repayment.
Interest Rate Swaps
The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps and caps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.  Interest rate caps designated as cash flow hedges involve the receipt of variable amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an upfront premium.
The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in Accumulated Other Comprehensive Income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During 2014, such derivatives were used to hedge the variable cash flows associated with variable-rate debt. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. During the year ended December 31, 2014 and 2013, the Company recorded $32,000 and $127,000, respectively, of hedge ineffectiveness in earnings attributable to the redesignation of several interest rate swaps.
Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate debt. During 2015, the Company estimates that an additional $6.9 million will be reclassified as an increase to interest expense. During the year ended December 31, 2014, the Company accelerated the reclassification of amounts in other comprehensive income to earnings as a result of the hedged forecasted transactions becoming probable not to occur. The accelerated amounts were a loss of $180,000.

On March 25, 2013, in connection with the purchase of the Teacher Retirement System of Texas' ("TRST") interest in the Tampa Fund II Assets, the Company assumed the remaining 70% of two interest rate swaps, which have a total notional amount of $34.6 million.
On May 31, 2013, the Company executed a floating-to-fixed interest rate swap for a notional amount of $13.5 million, associated with the first mortgage loan secured by Corporate Center IV in Tampa, Florida, which fixes LIBOR at 3.3% through October 8, 2018.
On June 12, 2013, the Company executed a floating-to-fixed interest rate swap for a notional amount of $120.0 million, associated with its $120.0 million unsecured term loan that fixes LIBOR at 1.6% for five years, which resulted in an initial all-in interest rate of 3.3%. The interest rate swap matures June 11, 2018.
On June 28, 2013, the Company modified the existing mortgage loan secured by Hayden Ferry II, an office property located in the Tempe submarket of Phoenix, Arizona. The loan modification eliminates quarterly principal payments of $625,000. As a result of the modification, loan payments are now interest-only through February 2015. The mortgage loan bears interest at LIBOR plus an applicable spread which ranges from 250 to 350 basis points. The Company entered into a floating-to-fixed interest rate swap which fixed LIBOR on the original loan at 1.5% through January 2018. Effective August 1, 2013, the Company entered into a second floating-to-fixed interest rate swap which fixes LIBOR at 1.7% through January 2018 on the additional notional amount associated with the loan modification. This loan is cross-defaulted with Hayden Ferry I, IV and V.
Effective June 12, 2013, the Company entered into a floating-to-fixed interest rate swap related to one-month LIBOR with a value of $120.0 million, locking LIBOR at 1.6% through June 11, 2018. On April 1, 2014, the Company dedesignated two of its existing floating-to-fixed interest rate swaps totaling $125.0 million that were previously associated with the $125.0 million five-year unsecured term loan and redesignated the swaps as a cash flow hedge of the risk of changes in cash flows attributable to changes in the benchmark interest rate for one-month LIBOR related to indexed interest payments made each month, regardless of the specific debt agreement from which they may flow. The two swaps totaling $125.0 million lock LIBOR at 0.7% through September 27, 2017. Additionally, on the same date, the Company entered into a new $5.0 million floating-to-fixed interest rate swap attributable to one-month LIBOR indexed interest payments made each month. The new $5.0 million swap has a fixed rate of 1.7%, an effective date of April 1, 2014 and matures on April 1, 2019.
The Company also terminated the $33.9 million swap designated to the Bank of America Center first mortgage. The net impact of the changes made to the existing swaps during the second quarter of 2014 resulted in a one-time increase in interest expense of approximately $121,000.
On April 1, 2014, the Company entered into a new $100.0 million floating-to-fixed interest rate swap attributable to one-month LIBOR indexed interest payments made each month. The $100.0 million swap has a fixed rate of 2.6%, an effective date of April 1, 2014 and a maturity date of March 31, 2021. The Company entered into this interest rate swap in connection with its $100.0 million seven-year unsecured term loan that bears interest at LIBOR plus the applicable margin which ranges from 1.75% to 2.30% based on the Company's overall leverage. The current spread associated with the loan is 1.75% resulting in an all-in rate of 4.31%.
The Company designated these swaps as cash flow hedges of the variable interest payments associated with the mortgage loans.

Fair Value Disclosures [Abstract]
Fair Values of Financial Instruments	Fair Values of Financial Instruments
	FASB ASC 820, "Fair Value Measurements and Disclosures" (“ASC 820”), defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 also provides guidance for using fair value to measure financial assets and liabilities. The Codification requires disclosure of the level within the fair value hierarchy in which the fair value measurements fall, including measurements using quoted prices in active markets for identical assets or liabilities (Level 1), quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active (Level 2), and significant valuation assumptions that are not readily observable in the market (Level 3).
	Assets and liabilities measured at fair value on a recurring basis were as follows (in thousands):
		As of December 31,
		2014				2013
		Carrying		Fair		Carrying		Fair
		Amount		Value		Amount		Value
	Financial Assets:
	Cash and cash equivalents	$	116,241	$	116,241	$	58,678	$	58,678
	Mortgage loan receivable	3,417		3,417		3,502		3,502
	Interest rate swap agreements	1,131		1,131		2,021		2,021
	Financial Liabilities:
	Mortgage notes payable	$	1,339,450	$	1,327,637	$	1,097,493	$	1,062,648
	Notes payable to banks	481,500		477,967		303,000		302,393
	Interest rate swap agreements	11,077		11,077		8,429		8,429
	The methods and assumptions used to estimate fair value for each class of financial asset or liability are discussed below:
	Cash and cash equivalents:  The carrying amounts for cash and cash equivalents approximate fair value.
	Mortgage notes payable:  The fair value of mortgage notes payable is estimated using discounted cash flow analysis, based on the Company's current incremental borrowing rates for similar types of borrowing arrangements. This information is considered a Level 2 input as defined by ASC 820.
	Mortgage loan receivable: The carrying amount for the mortgage loan approximates fair value.
	Notes payable to banks:  The fair value of the Company's notes payable to banks is estimated by discounting expected cash flows at current market rates. This information is considered a Level 2 input as defined by ASC 820.
	Interest rate swap agreements:  The fair value of the interest rate swaps is determined by estimating the expected cash flows over the life of the swap using the mid-market rate and price environment as of the last trading day of the reporting period. This information is considered a Level 2 input as defined by ASC 820.
	Non-financial assets and liabilities recorded at fair value on a non-recurring basis include the following: (1) non-financial assets and liabilities measured at fair value in a business combination; (2) impairment or disposal of long-lived assets measured at fair value; and (3) equity method investments or cost method investments measured at fair value due to an impairment. The fair values assigned to the Company's purchase price allocations utilize Level 2 and Level 3 inputs as defined by ASC 820. The fair value assigned to the long-lived assets for which there was impairment recorded utilize Level 2 inputs as defined by ASC 820.

On February 10, 2014, pursuant to an agreement entered into between CalSTRS and the Company, CalSTRS exercised an option to purchase 60% of Madison's former interest on the same terms as the Company for approximately $24.9 million. After giving effect to these transactions, the Company has a 40% interest in the CalSTRS joint venture and the Austin properties, with CalSTRS owning the remaining 60%.
	Murano Residential Condominium Project
	The Company also consolidates its Murano residential condominium project which it controls. The Company's unaffiliated partner's interest is reflected on the Company's consolidated balance sheets under the "Noncontrolling Interests" caption. The Company's partner has an ownership interest of 27%. Net proceeds from the project will be distributed, to the extent available, based on an order of preferences described in the partnership agreement. The Company may receive distributions, if any, in excess of its 73% ownership interest if certain return thresholds are met.
	Other Noncontrolling Interests
	The Company’s interest in its properties is held through the Operating Partnership.  All decisions relating to the operations and distributions of the Operating Partnership are made by the Company, which serves indirectly as the sole general partner of the Operating Partnership.  The Company owns a 95.5% interest in the Operating Partnership at December 31, 2014.  Noncontrolling interests in the Operating Partnership represents common Operating Partnership units that are not owned by the Company. Interests in the Operating Partnership are owned by limited partners who contributed properties and other assets to the Operating Partnership in exchange for common Operating Partnership units as part of merger and acquisition activities.  Limited partners have the right under the partnership agreement of the Operating Partnership to tender their units for redemption in exchange for cash or shares of the Company’s common stock, as selected by the Company in its sole and absolute discretion. Accordingly, the Company classifies the common Operating Partnership units held by limited partners in permanent equity because the Company may elect to issue shares of its common stock to limited partners exercising their redemption rights rather than using cash.
	Noncontrolling interests - unit holders include (a) 900,000 outstanding common units in the Operating Partnership that were issued in connection with the Company's acquisition of Lincoln Place, an office building located in the South Beach submarket in Miami, Florida, and (b) approximately 4.3 million outstanding common units in the Operating Partnership that were issued in exchange for outstanding limited partnership interests in TPGI in connection with the Mergers.
	Income is allocated to noncontrolling interests based on the weighted average percentage ownership during the year.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes
	The Company elected to be taxed as a REIT under the Internal Revenue Code, commencing with its taxable year ended December 31, 1997. In January 1998, the Company completed its reorganization into an UPREIT structure under which substantially all of the Company's real estate assets are owned by the Operating Partnership. Presently substantially all interests in the Operating Partnership are owned by the Company and a wholly owned subsidiary. To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement that it currently distribute at least 90% of its adjusted taxable income to its stockholders. It is management's current intention to adhere to these requirements and maintain the Company's REIT status, and the Company was in compliance with all REIT requirements at December 31, 2014. As a REIT, the Company generally will not be subject to corporate level federal income tax on taxable income it distributes currently 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 (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property, and to federal income and excise taxes on its undistributed taxable income. The Operating Partnership and its subsidiary, which is a pass-through entity generally not subject to federal and state income taxes, as all of the taxable income, gains and deductions are passed through its partners. However, the Operating Partnership is subject to income taxes in Texas. In addition, taxable income from non-REIT activities managed through taxable REIT subsidiaries is subject to federal, state and local income taxes.
	As of December 31, 2014, the Company had NOL carryforwards for federal income tax purposes of $254.8 million (including $88.4 million of NOLs from the Mergers). On December 10, 2012, the Company believes a change in ownership pursuant to Section 382 of the Code has occurred. Accordingly, $160.8 million of NOLs in existence as of December 10, 2012 are subject to an annual Section 382 limitation of $15.4 million. The historic NOLs of TPGI are also subject to Section 382 limitation. The Company's NOL carryforwards (including NOLs of TPGI) are subject to varying expiration dates beginning in 2018 through 2033. As of December 31, 2014, the Company recorded a full valuation allowance against its deferred tax asset associated with the net operating losses due to the uncertainty of future utilization. The utilization of these NOLs can cause the Company to incur a small alternative minimum tax.
	The Company's income differs for income tax and financial reporting purposes principally because real estate owned has a different basis for tax and financial reporting purposes, producing different gains upon disposition and different amounts of annual depreciation.
	The following reconciles GAAP net income (loss) to taxable income (loss) for the years ended December 31, 2014, 2013 and 2012 (in thousands) (Unaudited):

	-2	An estimated taxable income (loss) before adjustments is presented. The Company plans to file its 2014 tax return with the IRS on or before the extended due date of September 15, 2015.
	The Company has elected to treat certain consolidated subsidiaries as taxable REIT subsidiaries, which are tax paying entities for income tax purposes and are taxed separately from the Company. Taxable REIT subsidiaries may participate in non-real estate related activities and/or perform non-customary services for customers and are subject to federal and state income tax at regular corporate tax rates. On May 18, 2011, in connection with the combination of the Eola management company, the Company contributed the management company to a TRS wholly owned by the Operating Partnership.
	Certain income and expense items of taxable REIT subsidiaries are accounted for differently for financial reporting and income tax purposes. Deferred income tax assets and liabilities are determined based on the difference between the financial statement and the tax bases of assets and liabilities, applying enacted statutory income tax rates in effect for the year in which the differences are expected to reverse. As of December 31, 2014, the Company recorded a net deferred tax asset of $4.6 million. Deferred tax assets generally represent items that can be used as a tax deduction in the Company's tax returns in future years for which the Company has already recorded a tax benefit in its consolidated statement of operations.
	The significant components of the net deferred tax liabilities (assets) as of December 31, 2014 and 2013 are as follows (in thousands):

	FASB ASC 740-10-30 ("ASC 740-10-30") "Accounting for Income Taxes" subsection "Initial Measurement," requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some or all of the deferred tax asset will not be realized. In determining whether the deferred tax asset is realizable, the Company considers all available positive and negative evidence, including future reversal of existing taxable temporary differences, carryback potential, tax-planning strategies and its ability to generate sufficient taxable income in future years. During 2014, sufficient positive evidence became available to reach a conclusion that the valuation allowance is no longer needed and, as a result, the Company released the entire valuation allowance. This release resulted in the recognition of certain deferred tax assets and a decrease in income tax expense for the period.
	The components of income tax benefit (expense) for the years ended December 31, 2014, 2013, and 2012 are as follows (in thousands):

	Consolidated income (loss) subject to tax consists of pretax income or loss of taxable REIT subsidiaries. For the years ended December 31, 2014 and 2013 the Company had consolidated losses subject to tax of $2.6 million and $5.8 million, respectively. The reconciliation of income tax benefit (expense) computed at the U.S. statutory rate is shown below (in thousands):

The Company's federal income tax returns for tax years 2011 through 2014 remain open and subject to examination by the taxing authorities.
On December 19, 2013, the Company completed the Mergers. The Company assumed TPGI’s ownership interest in two wholly owned office properties in Houston, Texas and five office properties in Austin, Texas in the PKY/CalSTRS Austin, LLC discussed in "Note 4 - Investments in Unconsolidated Joint Ventures", and mortgage notes payable discussed in "Note 8—Capital and Financing Transactions". As set forth in the Merger Agreement, the parties to the Parent Merger intended that the Parent Merger be treated as a reorganization within the meaning of Section 368(a) of the Code. Assuming that, as intended, the Parent Merger qualified as a reorganization, because TPGI was a C corporation, the Company is subject to the rules applicable to REITs acquiring assets with "built-in gain" from C corporations in reorganizations. Pursuant to these rules, the Company is subject to corporate income tax to the extent that unrealized gain on historic TPGI assets (determined at the time of the Parent Merger) is recognized in taxable dispositions of such assets in the ten-year period following the Parent Merger. In addition, in connection with the Parent Merger, the Company succeeded to $88.4 million (or $30.9 million of deferred tax asset) of historic TPGI net operating loss carryovers (determined for U.S. federal income tax purposes), the utilization of which is subject to limitations under Section 382 of Code. In addition, the Company has deferred tax assets associated with California and Pennsylvania net operating losses of $1.4 million, and $2.8 million, respectively. ASC 740-10-30 requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some or all of the deferred tax asset will not be realized. Future realization of the deferred tax asset is dependent on the reversal of existing taxable temporary differences, carryback potential, tax-planning strategies and on us generating sufficient taxable income in future years. As of December 31, 2014, a valuation allowance has been established against the net deferred tax assets that will more likely than not be realized of $25.3 million, $1.0 million and $2.1 million for federal, California and Pennsylvania, respectively. At December 31, 2013, a deferred tax liability of approximately $11,000 has been recorded to reflect Texas Margin Tax for the sale of Four Points.
FASB ASC 740-10-25, "Accounting for Income Taxes" subsection "Recognition," clarifies the accounting for uncertainty in income taxes recognized in a company's financial statements. The interpretation prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The interpretation also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company's policy is to recognize interest and penalties related to unrecognized tax benefits as components of income tax expense. As of December 31, 2014, there is no interest or penalty associated with unrecognized tax benefits.
At December 31, 2014, the Company has recorded unrecognized tax benefits of approximately $6.9 million, acquired as part of the TPGI merger and, if recognized, would not affect its effective tax rate. The Company has sufficient NOLs to utilize for current or future tax liabilities.

Share-Based and Long-Term Compensation Plans	Share-Based and Long-Term Compensation Plans
	The Company grants share-based awards under the 2013 Equity Plan. Effective May 16, 2013, the stockholders of the Company approved the 2013 Equity Plan. The 2013 Equity Plan replaced the 2010 Omnibus Equity Incentive Plan (the "2010 Equity Plan") that authorized the grant of up to 600,000 equity-based awards to employees and directors of the Company. Outstanding awards granted under the 2010 Equity Plan continue to be governed by the 2010 Equity Plan. All of the employees of the Company and the Operating Partnership, employees of certain subsidiaries of the Company, non-employee directors, and any consultants or advisors to the Company and the Operating Partnership are eligible to participate in the 2013 Equity Plan.
	The 2013 Equity Plan authorizes the following types of awards: (1) stock options, including nonstatutory stock options and incentive stock options ("ISOs"); (2) stock appreciation rights; (3) restricted shares; (4) restricted share units; (5) profits interest units ("LTIPS units"); (6) dividend equivalent rights; and (7) other forms of awards payable in or denominated by reference to shares of common stock. Full value awards, i.e., awards other than options and stock appreciation rights, vest over a period of three years or longer, except that any full value awards subject to performance-based vesting must become vested over a period of one year or longer. The Compensation Committee may waive vesting requirements upon a participant’s death, disability, retirement or other specified termination of service or upon a change in control.
	The aggregate number of shares of the Company's common stock available for awards pursuant to the Plan is 3,250,000, including a maximum of 2,000,000 shares that may be granted pursuant to stock options or stock appreciation rights and a maximum of 1,250,000 shares that may be granted pursuant to other awards.
	If an award is canceled, forfeited or expires unvested or unexercised, or is settled in cash rather than in shares of common stock, then the shares covered by the portion of the award that is so canceled, forfeited, expired or settled will again become available for award under the plan. Shares repurchased by the Company at the same price paid by a participant will also become available for award under the plan, and the payment of dividend equivalents in cash in conjunction with any outstanding awards will not count against the Share Limit. Shares tendered in payment of an exercise or purchase price, tendered or retained to satisfy the Company’s tax withholding obligation, not issued upon exercise of a stock appreciation right to which they are subject and shares purchased in the open market with cash proceeds of option exercises will not be available for re-issuance under the plan. No shares may be made subject to a grant if that would cause an incentive stock option to fail to qualify as such under the tax code.
	Through December 31, 2014, the Company has granted stock options, LTIP units and RSUs (including time-vesting RSUs and performance-vesting RSUs) under the 2013 Equity Plan. As of December 31, 2014, the Company has restricted shares and deferred incentive share units outstanding under the 2010 Equity Plan.
	On May 12, 2011, the Board of Directors approved the Company's 2011 Employee Inducement Award Plan (the "2011 Inducement Plan") that authorized the grant of up to 149,573 restricted shares and/or deferred incentive share units to employees and directors of the Company in connection with the combination with Eola. The Plan shall continue in effect until the earlier of (a) its termination by the Board or (b) the date on which all of the shares of stock available for issuance under the Plan have been issued; provided that awards outstanding on that date shall survive in accordance with their terms. The Company no longer grants awards under the 2011 Inducement Plan.
	Long-Term Equity Incentives
	At December 31, 2014, a total of 1,293,750 shares underlying stock options had been granted to officers of the Company and remain outstanding under the 2013 Equity Plan. The stock options are valued at $5.4 million, which equates to an average price per share of $4.17. Each stock option will vest in increments of 25% per year on each of the first, second, third and fourth anniversaries of the grant date, subject to the grantee's continued service. At December 31, 2014, a total of 372,645 time-vesting RSUs had been granted to officers of the Company and remain outstanding. The time-vesting RSUs are valued at $6.9 million, which equates to an average price per share of $18.49. A total of 138,380 time-vesting RSU awards will vest in increments of 25% per year on each of the first, second, third and fourth anniversaries of the grant date and 234,265 time-vesting RSU awards will vest in increments of 33% per year on each of the first, second, and third anniversaries of the grant date, subject to the grantee's continued service.
	At December 31, 2014, a total of 300,636 LTIP units had been granted to officers of the Company and remain outstanding under the 2013 Equity Plan. LTIP units are a form of limited partnership interest issued by the Operating Partnership, and will be considered earned if, and only to the extent to which applicable total shareholder return, ("TSR"), performance measures are achieved during the performance period. Grant date fair values of the LTIP units are estimated using a Monte Carlo simulation model and the resulting expense is recorded regardless of whether the TSR performance measures are achieved if the required service is delivered. The grant date fair values are being amortized over expense over the period from the grant date to the date at which the awards, if any, would become vested. The LTIP units are valued at $2.8 million, which equates to an average price per share of $9.26. At December 31, 2014, a total of 131,888 performance-vesting RSUs had been granted to officers of the Company and remain outstanding under the 2013 Equity Plan. The performance-vesting RSUs are valued at approximately $1.2 million, which equates to an average price per share of $9.08. Each LTIP unit and performance-vesting RSU will vest based on the attainment of total stockholder return targets during the applicable performance period, subject to the grantee's continued service.
	At December 31, 2014, a total of 13,769 restricted shares had been granted to officers of the Company and remain outstanding under the 2010 Equity Plan. The restricted shares vest ratably over four years from the date of grant, with the last restricted shares vesting in January 2016. The restricted shares are valued at $201,000, which equates to an average price per share of $14.61. At December 31, 2013, a total of 6,855 deferred incentive share units had been granted to employees of the Company and remain outstanding under the 2010 Equity Plan. The deferred incentive share units are valued at $114,000, which equates to an average price per share of $16.63. The deferred incentive share units vest ratably over four years from the date of grant, with the last deferred incentive share units vesting in December 2015.
	On December 24, 2014, the Company entered into a Separation and General Release Agreement (the "Separation Agreement") wherein Henry F.

Mr. Pratt's remaining equity and equity-based awards, including 62,500 shares of company stock options, 29,941 LTIP units, 21,267 restricted stock units and 533 shares of restricted stock, were forfeited. $274,000 of compensation expense was recognized in general and administrative expenses on the Company's consolidated statements of operations and comprehensive income (loss) during the year ended December 31, 2014 related to the separation.

	On May 18, 2011, the Company closed on the Contribution Agreement pursuant to which Eola contributed its property management company (the “Management Company”) to the Company. Eola’s principals, which include certain officers of the Company, contributed the Management Company to the Company for initial consideration of $32.4 million in cash and contingent consideration of 1.8 million Operating Partnership units to Eola’s principals through an earn-out and earn-up arrangement based on the achievement by the Management Company of certain targeted annual gross fee revenue for the balance of 2011 and 2012. On December 30, 2011, the Company and certain officers of the Company, amended certain post-closing provisions of the Contribution Agreement to provide, among other things, that if the Management Company achieved annual revenues in excess of the original 2011 target, all Operating Partnership units subject to the 2011 earn-out, the 2012 earn-out and the earn-up will be deemed earned and paid when the 2011 earn-out payment is made. Based on the Management Company revenue for 2011, the target was achieved, and on February 28, 2012 an aggregate of 1.8 million Operating Partnership units were earned and issued to Eola’s principals. These OP units were exchanged during 2012 pursuant to their terms into an equal number of shares of the Company’s common Stock.
	Also in connection with the Eola contribution of its Management Company to the Company, a subsidiary of the Company made a $3.5 million preferred equity investment in an entity 21% owned by Mr. Heistand. This investment provides that the Company will be paid a preferred equity return equal to 7% per annum of the preferred equity outstanding. In 2014, 2013, and 2012 the Company received preferred equity distributions on this investment in the aggregate amounts of approximately $265,000, $225,000 and $246,000 respectively. This preferred equity investment was approved by the Company’s Board of Directors.

At a special meeting of stockholders held on July 31, 2012, the stockholders approved, among other things, the right to convert, at the option of the Company or the holders, shares of the Series E Preferred Stock into shares of the Company’s Common Stock. On August 1, 2012, the Company delivered a conversion notice to TPG Pantera and all shares of Series E Preferred Stock were converted into common stock on a one-for-one basis.

As provided in the Management Services Agreement, on June 5, 2012 the Company paid TPG Management a transaction fee of $6.0 million and reimbursed TPG Management $1.0 million of its reasonable out-of-pocket expenses incurred by it and its affiliates in connection with TPG Pantera’s investment in the Company. Furthermore, pursuant to the Management Services Agreement and in exchange for certain ongoing advisory and consulting services, the Company agreed to pay to TPG Management a monitoring fee equal to $600,000 for the first year following the closing under the Purchase Agreement and $1.0 million per year thereafter for so long as TPG Pantera has the right to appoint four of the directors of the Company’s Board of Directors. In each case, the monitoring fee will be reduced proportionately based on TPG Pantera’s board representation rights under the Stockholders Agreement, dated December 3, 2012, by and between the Company and TPG Pantera, as amended (the "Stockholders Agreement") as described below. On December 15, 2014, the Company and TPG Management amended the Management Services Agreement to provide that the monitoring fee is payable entirely in cash.

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation
	Parkway Properties, Inc. (the “Company") is a fully integrated, self-administered and self-managed real estate investment trust ("REIT") specializing in the acquisition, ownership and management of quality office and parking properties in high-growth submarkets in the Sunbelt region of the United States.  At January 1, 2015, the Company owned or had an interest in a portfolio of 51 office and parking properties located in eight states with an aggregate of approximately 17.2 million square feet (unaudited) of leasable space. The Company offers fee-based real estate services through its wholly owned subsidiaries, which in total managed and/or leased approximately 6.0 million square feet (unaudited) for third-party property owners at January 1, 2015.  Unless otherwise indicated, all references to square feet represent net rentable area.
	The Company is the sole general partner of Parkway Properties LP, (the "Operating Partnership" or "Parkway LP") and as of December 31, 2014, owned a 95.5% interest in the Operating Partnership. The remaining 4.5% interest consists of common units of limited partnership interest issued by the Operating Partnership to limited partners in exchange for contributions of properties to the Operating Partnership. As the sole general partner of the Operating Partnership, the Company has full and complete authority over the Operating Partnership’s day-to-day operations and management.
	The accompanying financial statements are prepared following U.S. generally accepted accounting principles ("GAAP") and the requirements of the Securities and Exchange Commission (the "SEC").
	The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries and joint ventures in which the Company has a controlling interest. The other partners' equity interests in the consolidated joint ventures are reflected as noncontrolling interests in the consolidated financial statements. The Company also consolidates subsidiaries where the entity is a variable interest entity ("VIE") and it is the primary beneficiary and has the power to direct the activities of the VIE and has the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. At December 31, 2014 and 2013, the Company did not have any VIEs that required consolidation. All significant intercompany transactions and accounts have been eliminated in the accompanying financial statements.
	The Company consolidates certain joint ventures where it exercises control over major operating and management decisions, or where the Company is the sole general partner and the limited partners do not possess kick-out rights or other substantive participating rights. The equity method of accounting is used for those joint ventures that do not meet the criteria for consolidation and where the Company does not control these joint ventures, but exercises significant influence. The cost method of accounting is used for investments in which the Company does not have significant influence. The investments are reviewed for impairment when indicators of impairment exist.
Business	Business
	The Company's operations are exclusively in the real estate industry, principally the operation, leasing, acquisition, development and ownership of office buildings.
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, the 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. Although the Company believes the assumptions and estimates made are reasonable and appropriate, as discussed in the applicable sections throughout these consolidated financial statements, different assumptions and estimates could materially impact reported results. The current economic environment has increased the degree of uncertainty inherent in these estimates and assumptions; therefore, changes in market conditions could impact the Company's future operating results. The Company's most significant estimates relate to impairments on real estate and other assets and purchase price allocations.
Real Estate Properties	Real Estate Properties
	Real estate properties are carried at cost less accumulated depreciation. Cost includes the carrying amount of the Company's investment plus any additional consideration paid, liabilities assumed, and improvements made subsequent to acquisition. Depreciation of buildings and building improvements is computed using the straight-line method over the estimated useful lives of the assets. Depreciation of tenant improvements, including personal property, is computed using the straight-line method over the lesser of useful life or the term of the lease involved. Maintenance and repair expenses are charged to expense as incurred.
	Balances of major classes of depreciable assets (in thousands) and their respective estimated useful lives are:
					December 31,
	Asset Category		Estimated Useful Life		2014		2013
	Land		Non-depreciable		$	412,578	$	278,780
	Buildings and garages		40 years		2,535,757		1,973,668
	Building improvements		7 to 40 years		52,715		78,450
	Tenant improvements		Lesser of useful life or term of lease		332,850		217,138
					$	3,333,900	$	2,548,036
	Depreciation expense, excluding amounts recorded in discontinued operations, related to these assets of $102.2 million, $69.0 million, and $45.3 million was recognized in 2014, 2013 and 2012, respectively.
	The Company evaluates its real estate assets upon occurrence of significant adverse changes in its operations to assess whether any impairment indicators are present that affect the recovery of the carrying amount. The carrying amount includes the net book value of tangible and intangible assets and liabilities. Real estate assets are classified as held for sale or held and used. The Company classifies certain assets as held for sale based on management having the authority and intent of entering into commitments for sale transactions to close in the next twelve months. The Company considers an office and parking property as held for sale once it has executed a contract for sale, allowed the buyer to complete its due diligence review and received a substantial non-refundable deposit. Until a buyer has completed its due diligence review of the asset, necessary approvals have been received and substantive conditions to the buyer's obligation to perform have been satisfied, the Company does not consider a sale to be probable. When the Company identifies an asset as held for sale, it estimates the net realizable value of such asset and discontinues recording depreciation on the asset. The Company records assets held for sale at the lower of carrying amount or fair value less cost to sell. If the fair value of the asset net of estimated selling costs is less than the carrying amount, the Company records an impairment loss. With respect to assets classified as held and used, the Company recognizes an impairment loss if the carrying amount is not recoverable and exceeds the sum of undiscounted future cash flows expected to result from the use and eventual disposition of the asset. Upon impairment, the Company recognizes an impairment loss to reduce the carrying value of the real estate asset to the estimate of its fair value. The cash flow and fair value estimates are based on assumptions about employing the asset for its remaining useful life. Factors considered in projecting future cash flows include, but are not limited to: existing leases, future leasing and terminations, market rental rates, capital improvements, tenant improvements, leasing commissions, inflation, discount rates, capitalization rates, and other known variables. This market information is considered a Level 3 input as defined by Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 820, "Fair Value Measurements and Disclosures," ("ASC 820").
	The Company recognizes gains on sales of real estate at times and in amounts determined in accordance with the accounting guidance for sales of real estate. The guidance takes into account the terms of the transaction and any continuing involvement, including in the form of management, leasing of space or financial assistance associated with the properties. If the sales criteria for the full accrual method are not met, then the Company defers gain recognition and accounts for the transaction by applying the deposit, finance, installment or cost recovery methods, as appropriate.
	During the year ended December 31, 2014, the Company recognized an impairment loss on real estate of $11.7 million in connection with Raymond James Tower in Memphis, Tennessee. During the year ended December 31, 2013, the Company recognized an impairment loss on real estate of $10.2 million in connection with Waterstone and Meridian in Atlanta, Georgia and Mesa Corporate Center in Phoenix, Arizona. During the year ended December 31, 2012, the Company recognized an impairment loss on real estate of $9.2 million in connection with two assets in Jackson, Mississippi and Columbia, South Carolina.
	At December 31, 2014, the Company classified Raymond James Tower in Memphis, Tennessee and Honeywell in Houston, Texas as assets held for sale. At December 31, 2013, the Company classified Mesa Corporate Center in Phoenix, Arizona and the Woodbranch Building in Houston, Texas as held for sale.
	Condominium Units
	The Company also consolidates its Murano residential condominium project which it controls. The Company's unaffiliated partner's interest is reflected on its consolidated balance sheets under the "Noncontrolling Interests" caption. The Company's partner has a stated ownership interest of 27%. Net proceeds from the project will be distributed, to the extent available, based on an order of preferences described in the partnership agreement. The Company may receive distributions, if any, in excess of its stated 73% ownership interest if certain return thresholds are met.
Purchase Price Allocation	Purchase Price Allocation
	The Company allocates the purchase price of real estate to tangible and intangible assets and liabilities based on fair values. Tangible assets consist of land, building, garage, building improvements and tenant improvements. Intangible assets and liabilities consist of the value of above and below market leases, lease costs, the value of in-place leases, and any value attributable to above or below market debt assumed with the acquisition.
	The Company may engage independent third-party appraisers to perform the valuations used to determine the fair value of these identifiable tangible and intangible assets. These valuations and appraisals use commonly employed valuation techniques, such as discounted cash flow analyses. Factors considered in these analyses include an estimate of costs during hypothetical expected lease-up periods considering current market conditions and costs to execute similar leases. The Company also considers information obtained about each property as a result of its pre-acquisition due diligence, marketing and leasing activities in estimating the fair value of the tangible and intangible assets acquired. The Company includes real estate taxes, insurance and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods depending on specific local market conditions and depending on the type of property acquired. Additionally, the Company estimates costs to execute similar leases including leasing commissions, legal and other related expenses to the extent that such costs are not already incurred in connection with a new lease origination as part of the transaction.
	The fair value of above or below market in-place lease values is the present value of the difference between the contractual amount to be paid pursuant to the in-place lease and the estimated current market lease rate expected over the remaining non-cancelable life of the lease. The capitalized above market lease values are amortized as a reduction of rental income over the remaining term of the respective leases. The capitalized below market lease values are amortized as an increase to rental income over the remaining term of the respective leases. Total amortization for above and below market leases, excluding amounts classified as discontinued operations, was a net increase (reduction) of rental income of $13.7 million, $(2.2) million and $(5.0) million for the years ended December 31, 2014, 2013 and 2012, respectively.
	As of December 31, 2014, the remaining amortization of net (above) and below market leases is projected as a net increase (decrease) to rental income as follows (in thousands):
		Amount
	2015	$	14,343
	2016	4,448
	2017	3,052
	2018	1,845
	2019	2,844
	Thereafter	(6,456		)
	Total	$	20,076
	The fair value of in-place leases is the present value associated with re-leasing the in-place lease as if the property was vacant. Factors to be considered include estimates of costs during hypothetical expected lease-up periods considering current market conditions and costs to execute similar leases. In estimating costs, the Company includes estimates of lost rentals at market rates during the expected lease-up periods. The value of at market in-place leases is amortized as a lease cost amortization expense over the expected life of the lease. Total amortization expense for the value of in-place leases, excluding amounts classified as discontinued operations, was $51.8 million, $26.9 million, and $15.0 million for the years ended December 31, 2014, 2013 and 2012, respectively.
	As of December 31, 2014, the remaining amortization expense for the value of in-place leases is projected as follows (in thousands):
		Amount
	2015	$	42,602
	2016	26,390
	2017	18,097
	2018	11,880
	2019	9,006
	Thereafter	21,254
	Total	$	129,229
	A separate component of the fair value of in-place leases is identified for the lease costs. The fair value of lease costs represents the estimated commissions and legal fees paid in connection with the current leases in place. Lease costs are amortized over the non-cancelable terms of the respective leases as lease cost amortization expense.
	In no event does the amortization period for intangible assets exceed the remaining depreciable life of the building. Should a customer terminate its lease, the unamortized portion of the tenant improvement, in-place lease value, lease cost and customer relationship intangibles would be charged to expense. Additionally, the unamortized portion of above market in-place leases would be recorded as a reduction to rental income and the below market in-place lease value would be recorded as an increase to rental income.
	The Company calculates the fair value of mortgage notes payable by discounting the remaining contractual cash flows on each instrument at the current market rate for these borrowings.
Capitalization of Costs	Capitalization of Costs
	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 certain costs of leasing personnel in connection with the completion of leasing arrangements.
Net Income (Loss) Per Common Share	Net Income (Loss) Per Common Share
	Basic earnings per share ("EPS") is computed by dividing income (loss) attributable to common stockholders by the weighted-average number of common shares outstanding for the year. In arriving at net income (loss) attributable to common stockholders, preferred stock dividends are deducted. Diluted EPS reflects the potential dilution that could occur if share equivalents such as employee stock options, restricted shares and deferred incentive share units were exercised or converted into common stock that then shared in the earnings of the Company.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts
	Accounts receivable are reduced by an allowance for amounts that the Company estimates to be uncollectible. The receivable balance is comprised primarily of rent and expense reimbursement income due from the customers. Management evaluates the adequacy of the allowance for doubtful accounts considering such factors as the credit quality of the customers, delinquency of payment, historical trends and current economic conditions. The Company provides an allowance for doubtful accounts for customer balances that are over 90 days past due and for specific customer receivables for which collection is considered doubtful.
Cash Equivalents	Cash Equivalents
	The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.
	Restricted Cash
	Restricted cash, which is included in receivables and other assets, primarily consists of security deposits held on behalf of the Company's tenants as well as capital improvements and real estate tax escrows required under certain loan agreements. There are restrictions on the Company's ability to withdraw these funds other than for their specified usage.
Noncontrolling Interest	Noncontrolling Interest
	A noncontrolling interest in a subsidiary is in most cases an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements and separate from the parent company's equity. In addition, consolidated net income is required to be reported at amounts that include the amounts attributable to both the parent and the noncontrolling interest and the amount of consolidated net income attributable to the parent and the noncontrolling interest are required to be disclosed on the face of the consolidated statements of operations and comprehensive income.
Revenue Recognition	Revenue Recognition
	Revenue from real estate rentals is recognized on a straight-line basis over the terms of the respective leases. The cumulative difference between lease revenue recognized under this method and contractual lease payment terms is recorded as straight-line rent receivable on the accompanying balance sheets. The straight-line rent adjustment increased revenue by $21.0 million, $14.6 million and $14.9 million in 2014, 2013, and 2012, respectively.
	When the Company is the owner of the tenant improvements, the leased space is ready for its intended use when the tenant improvements are substantially completed, at which point revenue recognition begins. In limited instances, when the tenant is the owner of the customer improvements, straight-line rent is recognized when the tenant takes possession of the unimproved space.
	The leases also typically provide for tenant reimbursement of a portion of common area maintenance, real estate taxes and other operating expenses.  Property operating cost recoveries from customers ("expense reimbursements") are recognized as revenue in the period in which the expenses are incurred. The computation of expense reimbursements is dependent on the provisions of individual customer leases. Most customers make monthly fixed payments of estimated expense reimbursements. The Company makes adjustments, positive or negative, to expense reimbursement income quarterly to adjust the recorded amounts to the Company's best estimate of the final property operating costs based on the most recent annual estimate. After the end of the calendar year, the Company computes each customer's final expense reimbursements and issues a bill or credit for the difference between the actual amount and the amounts billed monthly during the year. Differences between actual billed amounts and accrued amounts are considered immaterial.
	Management company income represents market-based fees earned from providing management, construction, leasing, brokerage and acquisition services to unconsolidated joint ventures, related parties, and third parties. Management fee income is computed and recorded monthly in accordance with the terms set forth in the management service agreements. Leasing and brokerage commissions, as well as salary and administrative fees, are recognized pursuant to the terms of the agreements at the time underlying leases are signed, which is the point at which the earnings process is complete and collection of the fees is reasonably assured. Fees relating to the purchase or sale of property are recognized when the earnings process is complete and collection of the fees is reasonably assured, which usually occurs at closing. All fees on Company-owned properties and consolidated joint ventures are eliminated in consolidation. The Company recognizes its share of fees earned from unconsolidated joint ventures in management company income.
	The Company has one high-rise condominium project. Under the provisions of FASB ASC 360-20, "Property, Plant and Equipment" subsection "Real Estate and Sales," revenue and costs for projects are recognized when all parties are bound by the terms of the contract, all consideration has been exchanged, any permanent financing for which the seller is responsible has been arranged and all conditions precedent to closing have been performed. This results in profit from the sale of condominium units recognized at closing. Revenue is recognized on the contract price of individual units. Total estimated costs are allocated to individual units which have closed on a relative value basis.
Investment in Unconsolidated Joint Ventures	Investment in Unconsolidated Joint Ventures
	The Company accounts for its investment in unconsolidated joint ventures under the equity method of accounting as the Company exercises significant influence, but does not maintain a controlling financial interest over these entities. These investments are recorded initially at cost and subsequently adjusted for cash contributions, distributions and equity in earnings (loss) of the unconsolidated joint ventures. Equity in earnings (loss) in unconsolidated joint ventures is allocated based on ownership or economic interest in each joint venture.
	The Company's investments in real estate joint ventures are reviewed for impairment periodically, and it records impairment charges when events or circumstances change indicating that a decline in the fair values below the carrying values has occurred and such decline is other-than-temporary. The ultimate realization of the investment in real estate joint ventures is dependent on a number of factors, including the performance of each investment and market conditions.
Amortization of Debt Origination Costs and Leasing Costs	Amortization of Debt Origination Costs and Leasing Costs
	Debt origination costs are deferred and amortized using a method that approximates the effective interest method over the term of the loan. Leasing costs are deferred and amortized using the straight-line method over the term of the respective lease.
Loss on Extinguishment of Debt	Loss on Extinguishment of Debt
	When outstanding debt is extinguished, the Company records any prepayment premium and unamortized loan costs.
Derivative Financial Instruments	Derivative Financial Instruments
	The Company recognizes all derivative instruments on the balance sheet at their fair value. Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive loss if a derivative is designated as part of a hedge transaction and, if it is, the type of hedge transaction. The ineffective portion of the hedge, if any, is immediately recognized in earnings.
Share-Based and Long-Term Compensation	Share-Based and Long-Term Compensation
	Compensation expense, net of estimated forfeitures, for service-based awards is recognized over the expected vesting period of such awards. The total compensation expense for the long-term equity incentive awards is based upon the fair value of the shares on the grant date, adjusted for estimated forfeitures. Time-vesting restricted shares, restricted share units ("RSUs"), and deferred incentive share units are valued based on the New York Stock Exchange closing market price of the Company's common shares as of the date of grant. The grant date fair value for awards that are subject to performance-based vesting and market conditions, including profits interest units ("LTIP units"), performance-vesting RSUs, and long-term equity incentive awards, is determined using a simulation pricing model developed to specifically accommodate the unique features of the awards. The total compensation expense for stock options is estimated based on the fair value of the options as of the date of grant using the Black-Scholes model.
Income Taxes	Income Taxes
	The Company elected to be taxed as a REIT under the Internal Revenue Code, commencing with its taxable year ended December 31, 1997. To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement that it currently distribute at least 90% of its adjusted taxable income to its stockholders. It is management's current intention to adhere to these requirements and maintain the Company's REIT status, and the Company was in compliance with all REIT requirements at December 31, 2014. As a REIT, the Company generally will not be subject to corporate level federal income tax on taxable income it distributes currently 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 (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property, and to federal income and excise taxes on its undistributed taxable income. In addition, taxable income from non-REIT activities managed through taxable REIT subsidiaries (collectively, the "TRS") is subject to federal, state and local income taxes.
Restructuring Charges	Restructuring Charges
	Restructuring charges reflected in general and administrative expenses in the accompanying consolidated statements of operations and comprehensive income (loss) relate primarily to one-time termination benefits. The Company recognizes these severance and other charges when the requirements of FASB ASC 420, "Exit or Disposal Cost Obligations," have been met regarding a plan of termination and when communication has been made to employees.
Fair Value Measurement	Fair Value Measurements
	Level 1 fair value inputs are quoted prices for identical assets or liabilities in active, liquid and visible markets such as stock exchanges. Level 2 fair value inputs are observable information for similar assets or liabilities in active or inactive markets, and appropriately consider counterparty creditworthiness in the valuations. Level 3 fair value inputs reflect the Company's best estimate of inputs and assumptions market participants would use in pricing an asset or liability at the measurement date. These inputs are unobservable in the market and significant to the valuation estimate.
	The methods and assumptions used to estimate fair value for each class of financial asset or liability are discussed below:
	Cash and cash equivalents:  The carrying amounts for cash and cash equivalents approximate fair value.
	Mortgage notes payable:  The fair value of mortgage notes payable is estimated using discounted cash flow analysis, based on the Company's current incremental borrowing rates for similar types of borrowing arrangements. This information is considered a Level 2 input as defined by ASC 820.
	Mortgage loan receivable: The carrying amount for the mortgage loan approximates fair value.
	Notes payable to banks:  The fair value of the Company's notes payable to banks is estimated by discounting expected cash flows at current market rates. This information is considered a Level 2 input as defined by ASC 820.
	Interest rate swap agreements:  The fair value of the interest rate swaps is determined by estimating the expected cash flows over the life of the swap using the mid-market rate and price environment as of the last trading day of the reporting period. This information is considered a Level 2 input as defined by ASC 820.
	Non-financial assets and liabilities recorded at fair value on a non-recurring basis include the following: (1) non-financial assets and liabilities measured at fair value in a business combination; (2) impairment or disposal of long-lived assets measured at fair value; and (3) equity method investments or cost method investments measured at fair value due to an impairment. The fair values assigned to the Company's purchase price allocations utilize Level 2 and Level 3 inputs as defined by ASC 820. The fair value assigned to the long-lived assets for which there was impairment recorded utilize Level 2 inputs as defined by ASC 820.
Reclassifications	Reclassifications
	Certain reclassifications have been made in the 2013 and 2012 consolidated financial statements to conform to the 2014 classifications with no impact on previously reported net income or equity.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	Effective January 1, 2014, the Company adopted guidance issued by FASB Accounting Standards Update ("ASU") No. 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." This update amends the criteria for reporting discontinued operations to, among other things, raise the threshold for disposals to qualify as discontinued operations, and only disposals that represent a strategic shift in operations that is material will be presented as discontinued operations. This update is effective for interim and annual reporting periods, beginning after December 15, 2014, with early adoption permitted. The Company presents 2014 property sales and will present future property sales, to the extent they do not represent a strategic shift in operations, in the continuing operations section of the consolidated statements of operations and comprehensive income (loss) with the exception of those properties previously included as held for sale at December 31, 2013. The Company's 2014 sales of the Woodbranch Building and Mesa Corporate Center are included in discontinued operations for the year ended December 31, 2014 as these properties were previously classified as held for sale at December 31, 2013. The Company's 2014 sales of the Schlumberger Building and 525 North Tryon are included in the continuing operations section of the consolidated statements of operations and comprehensive income (loss) as they were not previously classified as held for sale as of December 31, 2013 and do not qualify for inclusion in discontinued operations as they do not represent a strategic shift in the Company's operations.
	In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers." This update was initiated in a joint project between the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP and International Financial Reporting Standards that would: (1) remove inconsistencies and weaknesses in revenue requirements; (2) provide a more robust framework for addressing revenue issues; (3) improve comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets; (4) provide more useful information to users of financial statements through improved disclosure requirements; and (5) simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. This update is effective for interim and annual reporting periods, beginning after December 15, 2016, and early application is not permitted. 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.
	In August 2014, the FASB issued ASU No. 2014-15, "Presentation of Financial Statements - Going Concern." The amendments in this update provide guidance in GAAP about management's responsibilities to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. The main provision of the amendments are for an entity's management, in connection with the preparation of financial statements, to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued. Management's evaluation should be based on relevant conditions and events that are known or reasonably knowable at the date the financial statements are issued. When management identifies conditions or events that raise substantial doubt about an entity's ability to continue as a going concern, the entity should disclose information that enables users of the financial statements to understand all of the following: (1) principal conditions or events that raised substantial doubt about the entity's ability to continue as a going concern (before consideration of management's plans); (2) management's evaluation of the significance of those conditions or events in relation to the entity's ability to meet its obligations; and (3) management's plans that alleviated substantial doubt about the entity's ability to continue as a going concern or management's plans that are intended to mitigate the conditions or events that raise substantial doubt about the entity's ability to continue as a going concern. The amendments in this update are effective for interim and annual reporting periods after December 15, 2016 and early application is permitted. The Company is currently assessing this guidance for future implementation.
	In January 2015, the FASB issued ASU No. 2015-01, "Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items", (“ASU 2015-01”). ASU 2015-01 eliminates the concept of an extraordinary item from GAAP. As a result, an entity will no longer be required to segregate extraordinary items from the results of ordinary operations, to separately present an extraordinary item on its income statement, net of tax, after income from continuing operations or to disclose income taxes and earnings-per-share data applicable to an extraordinary item. However, ASU 2015-01 will still retain the presentation and disclosure guidance for items that are unusual in nature and occur infrequently. ASU 2015-01 will be effective for the Company’s fiscal year beginning January 1, 2016 and subsequent interim periods. The adoption of ASU 2015-015 is not expected to have a material effect on the Company’s consolidated financial statements.
	In February 2015, the FASB issued new consolidation guidance which makes changes to both the variable interest model and the voting model.  The new standard specifically eliminates the presumption in the current voting model that a general partner controls a limited partnership or similar entity unless that presumption can be overcome.  Generally, only a single limited partner that is able to exercise substantive kick-out rights will consolidate.  The new standard will be effective for the Company beginning on January 1, 2016 and early adoption is permitted, including adoption in an interim period.  The new standard must be applied using a modified retrospective approach by recording either a cumulative-effect adjustment to equity as of the beginning of the period of adoption or retrospectively to each period presented.  The Company is currently evaluating the impact of adopting the new standard on its consolidated financial statements.
