Organization, Basis of Presentation and Summary of Significant Accounting Policies

Acadia Realty Trust (the "Trust") and subsidiaries (collectively, the "Company"), is a fully-integrated equity real estate investment trust ("REIT") focused on the ownership, acquisition, redevelopment, and management of high-quality retail properties located primarily in high-barrier-to-entry, supply constrained, densely-populated metropolitan areas in the United States along the East Coast and in Chicago.

All of the Company’s assets are held by, and all of its operations are conducted through, Acadia Realty Limited Partnership (the "Operating Partnership") and entities in which the Operating Partnership owns an interest. As of December 31, 2013, the Trust controlled approximately 97% of the Operating Partnership as the sole general partner. As the general partner, the Trust is entitled to share, in proportion to its percentage interest, in the cash distributions and profits and losses of the Operating Partnership. The limited partners primarily represent entities or individuals that contributed their interests in certain properties or entities to the Operating Partnership in exchange for common or preferred units of limited partnership interest ("Common OP Units" or "Preferred OP Units") and employees who have been awarded restricted Common OP Units ("LTIP Units") as long-term incentive compensation (Note 15). Limited partners holding Common OP and LTIP Units are generally entitled to exchange their units on a one-for-one basis for common shares of beneficial interest of the Trust ("Common Shares"). This structure is referred to as an umbrella partnership REIT or "UPREIT."

As of December 31, 2013, the Company has ownership interests in 77 properties within its core portfolio, which consist of those properties either 100% owned, or partially owned through joint venture interests, by the Operating Partnership, or subsidiaries thereof, not including those properties owned through its funds ("Core Portfolio"). The Company also has ownership interests in 28 properties within its funds, Acadia Strategic Opportunity Fund I, LP ("Fund I"), Acadia Strategic Opportunity II, LLC ("Fund II"), Acadia Strategic Opportunity Fund III LLC ("Fund III") and Acadia Strategic Opportunity Fund IV LLC (("Fund IV") and together with Funds I, II, and III, the "Funds"). The 105 Core Portfolio and Fund properties primarily consist of urban/street retail, dense suburban neighborhood and community shopping centers and mixed-use properties with a strong retail component. In addition, the Company, together with the investors in the Funds, invest in operating companies through Acadia Mervyn Investors I, LLC ("Mervyns I"), Acadia Mervyn Investors II, LLC ("Mervyns II") and Fund II, all on a non-recourse basis.

The Operating Partnership is the sole general partner or managing member of the Funds and Mervyns I and II and earns fees or priority distributions for asset management, property management, construction, redevelopment, leasing, and legal services. Cash flows from the Funds and Mervyns I and II are distributed pro-rata to their respective partners and members (including the Operating Partnership) until each receives a certain cumulative return ("Preferred Return"), and the return of all capital contributions. Thereafter, remaining cash flow is distributed 20% to the Operating Partnership ("Promote") and 80% to the partners or members (including the Operating Partnership).

Notes:

(1) Fund I and Mervyns I have returned all capital and preferred return. The Operating Partnership is now entitled to a Promote on all future cash distributions.

(2) During 2013, a distribution of $47.1 million was made to the Fund II investors, including the Operating Partnership. This amount is subject to recontribution to Fund II until December 2016, if needed to fund the on-going development and construction of existing projects.

(3) Original committed capital of Fund III was $502.5 million. During 2012, this amount was reduced to $475.0 million.

Principles of Consolidation

The consolidated financial statements include the consolidated accounts of the Company and its controlling investments in partnerships and limited liability companies in which the Company has control in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 810 "Consolidation" ("ASC Topic 810"). The ownership interests of other investors in these entities are recorded as noncontrolling interests. All significant intercompany balances and transactions have been eliminated in consolidation. Investments in entities for which the Company has the ability to exercise significant influence over, but does not have financial or operating control, are accounted for using the equity method of accounting. Accordingly, the Company’s share of the earnings (or losses) of these entities are included in consolidated net income.

Variable interest entities are accounted for within the scope of ASC Topic 810 and are required to be consolidated by their primary beneficiary. The primary beneficiary of a variable interest entity is the enterprise that has the power to direct the activities that most significantly impact the variable interest entity’s economic performance and the obligation to absorb losses or the right to receive benefits of the variable interest entity that could be significant to the variable interest entity. Management has evaluated the applicability of ASC Topic 810 to its investments in certain joint ventures and determined that these joint ventures are not variable interest entities or that the Company is not the primary beneficiary and, therefore, consolidation of these ventures is not required. These investments are accounted for using the equity method of accounting.

The Company owns a 22.22% interest in an approximately one million square foot retail portfolio (the "Brandywine Portfolio") located in Wilmington, Delaware. Effective January 1, 2013, following certain changes in the financial and operating controls of the joint venture agreement, the Company now accounts for this investment on a consolidated basis.

Investments in and Advances to Unconsolidated Joint Ventures

The Company primarily accounts for its investments in unconsolidated joint ventures using the equity method as it does not exercise control over significant asset decisions such as buying, selling or financing nor is it the primary beneficiary under ASC Topic 810, as discussed above in most of these investments. The Company does have significant influence over most of these investments, which requires equity method accounting. Under the equity method, the Company increases its investment for its proportionate share of net income and contributions to the joint venture and decreases its investment balance by recording its proportionate share of net loss and distributions. The Company accounts for some of its investments under the cost method. Due to its minor ownership of three investments as well as the terms of the underlying operating agreements, the Company has no influence over such entities' operating and financial policies. Other than the minority investor rights to which the Company is entitled pursuant to statute, it has no rights other than to receive its pro-rata share of cash distributions as declared by the managers of these investments. The Company has no rights with respect to the control and operation of these investments vehicles, nor with the formulation and execution of business and investment policies. The Company recognizes income for distributions in excess of its investment where there is no recourse to the Company. For investments in which there is recourse to the Company, distributions in excess of the investment are recorded as a liability. Although the Company accounts for its investment in Albertson’s (Note 4) under the equity method of accounting, the Company adopted the policy of not recording its equity in earnings or losses of this unconsolidated affiliate until it receives the audited financial statements of Albertson’s to support the equity earnings or losses in accordance with ASC Topic 323, "Investments – Equity Method and Joint Ventures."

The Company periodically reviews its investment in unconsolidated joint ventures for other-than-temporary losses in investment value. Any decline that is not expected to be recovered is considered other than temporary and an impairment charge is recorded as a reduction in the carrying value of the investment. During 2012, the Company recorded an impairment charge of $2.0 million in connection with the estimated fair value in its investment in Mervyns. During the years ended December 31, 2013 and 2011, there were no impairment charges related to the Company’s investment in unconsolidated joint ventures.

Use of Estimates

Accounting principles generally accepted in the United States of America ("GAAP") require the Company’s management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The most significant assumptions and estimates relate to the valuation of real estate, depreciable lives, revenue recognition and the collectability of notes receivable and rents receivable. Application of these estimates and assumptions requires the exercise of judgment as to future uncertainties and, as a result, actual results could differ from these estimates.

Real Estate

Real estate assets are stated at cost less accumulated depreciation. Construction in progress includes costs for significant property expansion and redevelopment. Depreciation is computed on the straight-line basis over estimated useful lives of 30 to 40 years for buildings, the shorter of the useful life or lease term for tenant improvements and five years for furniture, fixtures and equipment. Expenditures for maintenance and repairs are charged to operations as incurred.

Upon acquisitions of real estate, the Company assesses the fair value of acquired assets and assumed liabilities (including land, buildings and improvements, and identified intangibles such as above and below market leases and acquired in-place leases and customer relationships) and acquired liabilities in accordance with ASC Topic 805 "Business Combinations" and ASC Topic 350 "Intangibles – Goodwill and Other," and allocates the acquisition price based on these assessments. Fixed-rate renewal options have been included in the calculation of the fair value of acquired leases where applicable. To the extent there were fixed-rate options at below-market rental rates, the Company included these along with the current term below-market rent in arriving at the fair value of the acquired leases. The discounted difference between contract and market rents is being amortized over the remaining applicable lease term, inclusive of any option periods. The Company assesses fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends, and market/economic conditions that may affect the property.

The Company capitalizes certain costs related to the development and redevelopment of real estate including pre-construction costs, interest, real estate taxes, insurance, construction costs and salaries and related costs of personnel directly involved with the specific project. Additionally, the Company capitalizes interest costs related to development and redevelopment activities. Capitalization of these costs begin when the activities and related expenditures commence, and cease when the property is held available for occupancy upon substantial completion of tenant improvements, but no later than one year from the completion of major construction activity at which time the project is placed in service and depreciation commences.

The Company reviews its long-lived assets for impairment when there is an event or a change in circumstances that indicates that the carrying amount may not be recoverable. The Company measures and records impairment losses and reduces the carrying value of properties when indicators of impairment are present and the expected undiscounted cash flows related to those properties are less than their carrying amounts. In cases where the Company does not expect to recover its carrying costs on properties held for use, the Company reduces its carrying costs to fair value, and for properties held for sale, the Company reduces its carrying value to the fair value less costs to sell. During the year ended December 31, 2013, the Company determined that the values of the Walnut Hill Plaza and Fund III's Sheepshead Bay property were impaired. Accordingly, impairment charges of $1.5 million and $6.7 million, respectively were recorded. The Operating Partnership's share of the impairment charge related to Sheepshead Bay was $1.3 million. During the year ended December 31, 2011, the Company determined that the value of the Granville Centre owned by Fund I was impaired. Accordingly, an impairment loss of $6.9 million was recorded, of which the Operating Partnership's share was $1.5 million. During the year ended December 31, 2012, no impairment charges were recorded. Management does not believe that the values of any other properties within the portfolio are impaired as of December 31, 2013.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company recognizes property sales in accordance with ASC Topic 970 "Real Estate." The Company generally records the sales of operating properties and outparcels using the full accrual method at closing when the earnings process is deemed to be complete. Sales not qualifying for full recognition at the time of sale are accounted for under other appropriate deferral methods. The Company evaluates the held-for-sale classification of its real estate each quarter. Assets that are classified as held for sale are recorded at the lower of their carrying amount or fair value less cost to sell. Assets are generally classified as held for sale once management has initiated an active program to market them for sale and has received a firm purchase commitment. The results of operations of these real estate properties are reflected as discontinued operations in all periods presented.

On occasion, the Company will receive unsolicited offers from third parties to buy individual Company properties. Under these circumstances, the Company will classify the properties as held for sale when a sales contract is executed with no contingencies and the prospective buyer has funds at risk to ensure performance.

Involuntary Conversion of Asset

The Company experienced significant flooding resulting in extensive damage to one of its properties during September 2011. Costs related to the clean-up and redevelopment were insured for an amount sufficient that would allow for full restoration of the property. Loss of rents during the redevelopment were covered by business interruption insurance subject to a $0.1 million deductible.

In accordance with ASC Topic 360 "Property, Plant and Equipment" and as a result of the above-described property damage, the Company had recorded a write-down of the asset's carrying value of approximately $1.4 million, as well as an insurance recovery in the same amount that is included in Prepaid Expenses and Other Assets in the accompanying consolidated balance sheets as of December 31, 2011. The Company also provided a $0.1 million provision in the 2011 consolidated statement of income for its exposure to the insurance deductible attributable to the loss of rents. During the years ended December 31, 2012 and 2011, the Company received insurance proceeds of approximately $3.7 million and $6.9 million, respectively. The Company recognized a gain on involuntary conversion of $2.4 million in 2012 as these proceeds exceeded the asset's net basis.

Deferred Costs

Fees and costs paid in the successful negotiation of leases are deferred and amortized on a straight-line basis over the terms of the respective leases. Fees and costs incurred in connection with obtaining financing are deferred and amortized over the term of the related debt obligation. The Company capitalizes salaries, commissions and benefits related to time spent by leasing and legal department personnel involved in originating leases.

Management Contracts

Income from management contracts is recognized on an accrual basis as such fees are earned. The initial acquisition costs of any management contracts are amortized over the estimated lives of the contracts acquired.

Revenue Recognition and Accounts Receivable

Leases with tenants are accounted for as operating leases. Minimum rents are recognized, net of any rent concessions or tenant lease incentives, including free rent, on a straight-line basis over the term of the respective leases, beginning when the tenant is entitled to take possession of the space. As of December 31, 2013 and 2012, unbilled rents receivable relating to the straight-lining of rents of $23.1 million and $23.6 million, respectively are included in Rents Receivable, net on the accompanying consolidated balance sheets. Certain of these leases also provide for percentage rents based upon the level of sales achieved by the tenant. Percentage rent is recognized in the period when the tenants’ sales breakpoint is met. In addition, leases typically provide for the reimbursement to the Company of real estate taxes, insurance and other property operating expenses. These reimbursements are recognized as revenue in the period the related expenses are incurred.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization, Basis of Presentation and Summary of Significant Accounting Policies, continued

The Company makes estimates of the uncollectability of its accounts receivable related to tenant revenues. An allowance for doubtful accounts has been provided against certain tenant accounts receivable that are estimated to be uncollectible. Once the amount is ultimately deemed to be uncollectible, it is written off. Rents receivable at December 31, 2013 and 2012 are shown net of an allowance for doubtful accounts of $6.0 million and $6.1 million, respectively.

Notes Receivable and Preferred Equity

Notes receivable and preferred equity investments are intended to be held to maturity and are carried at amortized cost. Interest income from notes receivable and preferred equity investments are recognized on the effective interest method over the expected life of the loan. Under the effective interest method, interest or fees collected at the origination of the investment or the payoff of the investment are recognized over the term of the loan as an adjustment to yield.

Allowances for real estate notes receivable are established based upon management’s quarterly review of the investments. In performing this review, management considers the estimated net recoverable value of the loan as well as other factors, including the fair value of any collateral, the amount and status of any senior debt, and the prospects for the borrower. Because this determination is based upon projections of future economic events, which are inherently subjective, the amounts ultimately realized from the loans may differ materially from their carrying values at the balance sheet date. Interest income recognition is generally suspended for loans when, in the opinion of management, a full recovery of income and principal becomes doubtful. Income recognition is resumed when the suspended loan becomes contractually current and performance is demonstrated to be resumed.

During 2012, the Company provided a $0.4 million net reserve on note receivables as a result of changes in the value of the underlying collateral properties.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents are maintained at financial institutions and, at times, balances may exceed the federally insured limit by the Federal Deposit Insurance Corporation. The Company has never experienced any losses related to these balances.

Restricted Cash and Cash in Escrow

Restricted cash and cash in escrow consist principally of cash held for real estate taxes, construction costs, property maintenance, insurance, minimum occupancy and property operating income requirements at specific properties as required by certain loan agreements.

Income Taxes

The Company has made an election to be taxed, and believes it qualifies, as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the "Code"). To maintain REIT status for Federal income tax purposes, the Company is generally required to distribute at least 90% of its REIT taxable income to its shareholders as well as comply with certain other income, asset and organizational requirements as defined in the Code. Accordingly, the Company is generally not subject to Federal corporate income tax to the extent that it distributes 100% of its REIT taxable income each year.

Although it may qualify for REIT status for Federal income tax purposes, the Company is subject to state income or franchise taxes in certain states in which some of its properties are located. In addition, taxable income from non-REIT activities managed through the Company’s taxable REIT subsidiaries ("TRS") is fully subject to Federal, state and local income taxes.

The Company accounts for TRS income taxes under the liability method as required by ASC Topic 740, "Income Taxes." Under the liability method, deferred income taxes are recognized for the temporary differences between the GAAP basis and tax basis of the TRS income, assets and liabilities.

In accordance with ASC Topic 740, the Company believes that it has appropriate support for the income tax positions taken and, as such, does not have any uncertain tax positions that, if successfully challenged, could result in a material impact on the Company's financial position or results of operation. The prior three years' income tax returns are subject to review by the Internal Revenue Service. The Company recognizes potential interest and penalties related to uncertain tax positions as a component of the provision for income taxes.

Stock-based Compensation

The Company accounts for stock-based compensation pursuant to ASC Topic 718, "Compensation – Stock Compensation." As such, all equity based awards are reflected as compensation expense in the Company’s consolidated financial statements over their vesting period based on the fair value at the date of grant.

Recent Accounting Pronouncements

During July 2013, the FASB issued Accounting Standards Update ("ASU") No. 2013-11, "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists." ASU 2013-11 requires an entity to present an unrecognized tax benefit relating to a net operating loss carryforward, a similar tax loss or a tax credit carryforward as a reduction to a deferred tax asset except in certain situations. To the extent the net operating loss carry forward, similar tax loss or tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of the tax position or the tax law of the applicable jurisdiction does not require the entity to use and the entity does not intend to use the deferred tax asset for such purpose, the unrecognized tax benefit should be presented as a liability. ASU No. 2013-11 is effective for fiscal years, and interim periods within those years, beginning on or after December 15, 2013. The adoption of ASU No. 2013-11 is not expected to have a material impact on the Company's financial condition or results of operations.

During February 2013, the FASB issued Accounting Standards Update ("ASU") No. 2013-03, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income." ASU 2013-03 requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. ASU is effective prospectively for reporting periods beginning after December 15, 2012. The adoption of ASU 2013-03 did not have a material impact on the Company's financial condition or results of operations.

	Fund III
	Fund III had previously acquired a $23.0 million note receivable at a discounted price of $18.5 million during April 2012. The note receivable, which was scheduled to mature in May 2012, was collateralized by a 79,526 square foot shopping center located in Brooklyn, New York ("Nostrand Place"). The Company commenced foreclosure proceedings, but ultimately agreed to a settlement with the unaffiliated borrower. Pursuant to the settlement, in February 2013, Fund III and the borrower formed a joint venture whereby Fund III contributed its interest in the note for a 99% controlling interest in the joint venture, and the borrower contributed the deed to Nostrand Place in exchange for a 1% interest in the joint venture. As a result, Fund III consolidates its investment in Nostrand Place.
	The Company expensed $0.8 million of acquisition costs for the year ended December 31, 2013 related to Fund III.

	Segment Reporting
	The Company has three reportable segments: Core Portfolio, Funds and Structured Financing. The accounting policies of the segments are the same as those described in the summary of significant accounting policies. The Company evaluates property performance primarily based on net operating income before depreciation, amortization and certain nonrecurring items. Investments in the Core Portfolio are typically held long-term. Given the contemplated finite life of the Funds, these investments are typically held for shorter terms. Fees earned by the Company as the general partner or managing member of the Funds are eliminated in the Company’s consolidated financial statements. The following table sets forth certain segment information for the Company, reclassified for discontinued operations, as of and for the years ended December 31, 2013, 2012 and 2011 (does not include unconsolidated affiliates or discontinued operations):

	Investments In and Advances to Unconsolidated Affiliates
	Core Portfolio
	The Company owns a 49% interest in a 311,000 square foot shopping center located in White Plains, New York ("Crossroads"), a 50% interest in an approximately 28,000 square foot retail portfolio located in Georgetown, Washington D.C. (the "Georgetown Portfolio") and a 22.22% interest in an approximately 20,000 square foot retail property located in Wilmington, Delaware ("Route 202 Shopping Center"). As our joint venture partners in these investments maintain operating control, these are accounted for under the equity method.
	Funds
	Fund Investments
	During 2013, Fund II, through a joint venture ("City Point Tower I") with an unaffiliated entity, executed an agreement to acquire the development rights for one of the residential components of Fund II's City Point project. Fund II contributed $1.1 million of cash and $6.8 million of prepaid ground rent and previously incurred construction costs into this joint venture.
	The unaffiliated partners for Fund II's investment in City Point Tower I, Fund III's investments in the Lincoln Road Portfolio, Parkway Crossing, Arundel Plaza and the White City Shopping Center as well as Fund IV's investments in the Lincoln Road Portfolio, 1701 Belmont Avenue, 2819 Kennedy Boulevard and Promenade at Manassas maintain control over these entities. The Company accounts for these investments under the equity method as it has the ability to exercise significant influence, but does not have any rights with respect to financial or operating control.
	Self-Storage Management, a Fund III investment, was determined to be a variable interest entity. Management has evaluated the applicability of ASC Topic 810 to this joint venture and determined that the Company is not the primary beneficiary and, therefore, consolidation of this venture is not required. The Company accounts for this investment using the equity method of accounting.
	RCP Venture
	The Funds, together with two unaffiliated partners formed an investment group, the RCP Venture, for the purpose of making investments in surplus or underutilized properties owned by retailers and, in some instances, the retailers' operating company. The RCP Venture is neither a single entity nor a specific investment and the Company has no control or rights with respect to the formation and operation of these investments. The Company has made these investments through its subsidiaries, Mervyns I, Mervyns II and Fund II, (together the "Acadia Investors"), all on a non-recourse basis. Through December 31, 2013, the Acadia Investors have made investments in Mervyns Department Stores ("Mervyns") and Albertsons including additional investments in locations that are separate from these original investments ("Add-On Investments"). Additionally, they have invested in Shopko, Marsh and Rex Stores Corporation (collectively "Other RCP Investments"). The Company accounts for its investments in Mervyns and Albertsons on the equity method as it has the ability to exercise significant influence, but does not have any rights with respect to financial or operating control. The Company accounts for its investments in its Add-On Investments and Other RCP Investments on the cost method as it does not have any influence over such entities' operating and financial policies nor any rights with respect to the control and operation of these entities.

	The Company accounts for the original investments in Mervyns and Albertson’s under the equity method of accounting as the Company has the ability to exercise significant influence, but does not have financial or operating control.
	The Company accounts for the Add-On Investments and Other RCP Investments under the cost method. Due to its minor ownership interest, based on the size of the investments as well as the terms of the underlying operating agreements, the Company has no influence over such entities' operating and financial policies. Other than the minority investor rights to which the Company is entitled pursuant to statute, it has no rights other than to receive its pro-rata share of cash distributions as declared by the managers of the Add-On Investments and Other RCP Investments. The Company has no rights with respect to the control and operation of these investment vehicles, nor with the formulation and execution of business and investment policies.

	During December 2013, the Company received a $1.6 million payment on an $8.0 million note representing the release price on one of the three properties on which the note was collateralized. The balance of $6.4 million remains outstanding.
	During December 2013, the Company made a preferred equity investment in a joint venture for $13.0 million. The joint venture owns a property and the agreement provides the Company with the first right of offer to purchase the property should the Members decide to sell. The investment has a mandatory redemption date of September 1, 2017 and earns a preferred return rate of 8.1%.
	During December 2013, the Company made a $12.0 million loan, which is collateralized by a property located in Manhattan. The loan bears interest at 7.7% and matures January 1, 2015.
	During December 2013, the Company amended a $25.0 million loan which bore interest at 9.0% and was set to mature January 1, 2014.

This note is collateralized by a property which is currently under contract to acquire.
	During December 2013, the Company made a $3.0 million loan in conjunction with the acquisition of a long term master lease for a property located in Manhattan. The loan is collateralized by operating partnership units given to the buyer as part of the purchase price. The loan bears interest at LIBOR plus 2.5% and matures December 2020.
	The Company monitors the credit quality of its notes receivable on an ongoing basis and considers indicators of credit quality such as loan payment activity, the estimated fair value of the underlying collateral, the seniority of the Company's loan in relation to other debt secured by the collateral and the prospects of the borrower. As of December 31, 2013, the Company held six non-performing notes aggregating $18.6 million for which payment was delinquent. Based primarily on the indicators noted above, the Company has established a reserve of $3.7 million as of December 31, 2013 related to these notes.

Debt Disclosure [Abstract]	'
Convertible Notes Payable	'
	Convertible Notes Payable
	In December 2006 and January 2007, the Company issued a total of $115.0 million of convertible notes with a fixed interest rate of 3.75% due 2026 (the "Convertible Notes"). The Convertible Notes were issued at par and require interest payments semi-annually in arrears on June 15 and December 15 of each year. The Convertible Notes are unsecured, unsubordinated obligations and rank equally with all other unsecured and unsubordinated indebtedness. The Convertible Notes were accounted for under ASC Topic 470-20, “Debt with Conversion and Other Options,” which required the Company to allocate the proceeds from the issuance between a debt component and an equity component. The resulting discount on the debt component was amortized over the period the convertible debt was expected to be outstanding, which was December 11, 2006 to December 20, 2011, as additional non-cash interest expense. Until December 20, 2011, the Convertible Notes had an effective interest rate of 6.03% after giving effect to ASC Topic 470-20. The additional non-cash interest expense recognized in the Consolidated Statements of Income was $0.8 million for the year ended December 31, 2011.
	As of December 31, 2013, $114.6 million of the Convertible Notes have been repurchased. The remaining Convertible Notes bear interest at 3.75% and the Company has the right to redeem the notes, in whole, or in part, at any time, and from time to time, for cash equal to 100% of the principal amount of the notes plus any accrued and unpaid interest to, but not including, the redemption date. The Holders of notes may require the Company to repurchase their notes, in whole or in part, on December 15, 2016 and December 15, 2021 for cash equal to 100% of the principal amount of the notes to be repurchased plus any accrued and unpaid interest to, but not including, the repurchase date.

	Financial Instruments and Fair Value Measurements
	The FASB’s fair value measurements and disclosure guidance requires the valuation of certain of the Company’s financial assets and liabilities, based on a three-level fair value hierarchy. Market participant assumptions obtained from sources independent of the Company are observable inputs that are classified within Levels 1 and 2 of the hierarchy, and the Company’s own assumptions about market participant assumptions are unobservable inputs classified within Level 3 of the hierarchy.
	The following table presents the Company’s fair value hierarchy for those assets and liabilities measured at fair value on a recurring basis as of December 31, 2013:
	(dollars in thousands)	Level 1		Level 2		Level 3
	Assets
	Derivative financial instruments	$	—	$	3,114	$	—
	Liabilities
	Derivative financial instruments	$	—	$	2,066	$	—
	During the year ended December 31, 2011, the Company determined that the value of the Granville Centre owned by Fund I was impaired and recorded an impairment loss of $6.9 million (Note 1). The Company estimated the property's fair value by using projected future cash flows, which it determined were not sufficient to recover the property's net book value. The inputs used to determine the fair value of the Granville Centre were classified as Level 3 under authoritative guidance for fair value measurements.
	During the year ended December 31, 2012, the Company determined that carrying value in its investment in Mervyns was impaired and recorded an impairment of $2.0 million (Note 1). The analysis performed consisted of discounted cash flows which were used to determine the fair value of the Mervyns investment and were classified as Level 3 under authoritative guidance for fair value measurements.
	During the year ended December 31, 2013, the Company determined that the value of the Walnut Hill Plaza was impaired and recorded an impairment loss of $1.5 million (Note 1). The Company estimated the fair value by using projected future cash flows, which it determined were not sufficient to recover the property's net book value. The inputs used to determine this fair value are classified within Level 3 under authoritative guidance for fair value measurements.
	During the year ended December 31, 2013, the Company entered into a firm contract to sell Sheepshead Bay for $20.2 million. As this amount is less than the carrying cost, the Company recorded an impairment loss of $6.7 million (Note 1).

	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
	10. Financial Instruments and Fair Value Measurements, continued
	Derivative Financial Instruments
	The FASB’s derivative and hedging guidance establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. As required by the FASB guidance, the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecast transactions, are considered cash flow hedges.
	For derivatives designated as fair value hedges, changes in the fair value of the derivative and the hedged item related to the hedged risk are recognized in earnings. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive (loss) income (outside of earnings) and subsequently reclassified to earnings when the hedged transaction affects earnings, and the ineffective portion of changes in the fair value of the derivative is recognized directly in earnings. The Company assesses the effectiveness of each hedging relationship by comparing the changes in fair value or cash flows of the derivative hedging instrument with the changes in fair value or cash flows of the designated hedged item or transaction. For derivatives not designated as hedges, changes in fair value would be recognized in earnings.
	As of December 31, 2013, the Company’s derivative financial instruments consisted of 11 interest rate LIBOR swaps with an aggregate notional value of $179.7 million, which fix interest at rates from 0.52% to 3.77%, and mature between May 2015 and April 2023. The Company also has four derivative financial instruments with a notional value of $140.7 million which cap interest rates ranging from 3.0% to 4.3% and mature between July 2015 and April 2018. The fair value of the derivative liability of these instruments, which is included in other liabilities in the consolidated balance sheets, totaled $2.0 million and $4.4 million at December 31, 2013 and 2012, respectively. The fair value of these derivative instruments, included in prepaid expenses and other assets in the Consolidated Balance Sheets, totaled $3.1 million at December 31, 2013. The notional value does not represent exposure to credit, interest rate or market risks.
	These derivative instruments have been designated as cash flow hedges and hedge the future cash outflows on variable rate mortgage debt. Such instruments are reported at the fair value reflected above. As of December 31, 2013 and 2012, unrealized income and (losses) totaling $1.1 million and ($4.3 million), respectively, were reflected in accumulated other comprehensive income (loss). It is estimated that approximately $2.4 million included in accumulated other comprehensive income related to derivatives will be reclassified to interest expense in the 2014 results of operations.
	As of December 31, 2013 and 2012, no derivatives were designated as fair value hedges or hedges of net investments in foreign operations. Additionally, the Company does not use derivatives for trading or speculative purposes and currently does not have any derivatives that are not designated as hedges. As of December 31, 2013, none of the Company’s hedges were ineffective.
	Financial Instruments
	Certain of the Company’s assets and liabilities meet the definition of financial instruments. Except as disclosed below, the carrying amounts of these financial instruments approximates their fair value due to the short-term nature of such accounts.
	The Company has determined the estimated fair values of the following financial instruments within Level 2 of the hierarchy by discounting future cash flows utilizing a discount rate equivalent to the rate at which similar financial instruments would be originated at the reporting date:
		December 31, 2013				December 31, 2012

	Share Incentive Plan
	During 2012, the Company terminated the 1999 and 2003 Plans and adopted the Amended 2006 Plan. The Amended 2006 Plan increased the authorization to issue options, Restricted Shares and LTIP Units (collectively "Awards") available to officers and employees by 1.9 million shares to 2.1 million shares. Options are granted by the Compensation Committee (the "Committee"), which currently consists of three non-employee Trustees, and will not have an exercise price less than 100% of the fair market value of the Common Shares and a term of greater than ten years at the grant date. Vesting of options is at the discretion of the Committee. The Committee determines the restrictions placed on Awards, including the dividends or distributions thereon and the term of such restrictions. The Committee also determines the award and vesting of the awards based on the attainment of specified performance objectives of the Company within a specified performance period.
	On February 22, 2013, the Company issued a total of 284,447 LTIP Units and 590 Restricted Share Units to officers of the Company and 11,880 Restricted Share Units to other employees of the Company. Vesting with respect to these awards is generally recognized ratably over the five annual anniversaries following the issuance date. Vesting with respect to 16% of the awards issued to officers is also generally subject to achieving certain Company performance measures. LTIP Units are similar to Restricted Shares but provide for a quarterly partnership distribution in a like amount as paid to Common OP Units. This distribution is paid on both unvested and vested LTIP Units. The LTIP Units are convertible into Common OP Units and Common Shares upon vesting and a revaluation of the book capital accounts.
	These awards were measured at their fair value as if they were vested on the grant date. Fair value was established as the market price of the Company's Common Shares as of the close of trading on the day preceding the grant date.
	The total value of the above Restricted Share Units and LTIP Units as of the grant date was $7.9 million. The weighted average fair value for Restricted Shares and LTIP Units granted for the years ended December 31, 2013, 2012 and 2011 were $26.40, $22.31 and $19.08, respectively.
	Total long-term incentive compensation expense, including the expense related to the above mentioned plans, was $7.3 million, $3.6 million and $4.0 million for the years ended December 31, 2013, 2012 and 2011, respectively and is recorded in General and Administrative on the consolidated statements of income.

	15. Share Incentive Plan, continued
	On May 15, 2013, the Company issued 20,718 Restricted Shares to Trustees of the Company in connection with Trustee fees. Vesting with respect to 10,950 of the Restricted Shares will be on the first anniversary of the date of issuance and 9,768 of the Restricted Shares vest over three years with 33% vesting on each of the next three anniversaries of the issuance date. The Restricted
	Shares do not carry voting rights or other rights of Common Shares until vesting and may not be transferred, assigned or pledged until the recipients have a vested non-forfeitable right to such shares. Dividends are not paid currently on unvested Restricted Shares, but are paid cumulatively from the issuance date through the applicable vesting date of such Restricted Shares. Trustee fee expense of $0.3 million for the year ended December 31, 2013 has been recognized in the accompanying consolidated statement of income related to this issuance.
	In 2009, the Company adopted the Long Term Investment Alignment Program (the "Program") pursuant to which the Company may award units primarily to senior executives which would entitle them to receive up to 25% of any future Fund III Promote when and if such Promote is ultimately realized. The Company has awarded all of the units under the Program, and these units were determined to have no value at issuance or as of December 31, 2013. In accordance with ASC Topic 718, "Compensation - Stock Compensation," compensation relating to these awards will be recorded based on the change in the estimated fair value at each reporting period.
	As of December 31, 2013, the Company had 92,086 options outstanding to officers and employees and 21,000 options outstanding to non-employee Trustees of the Company all of which have vested. These options are for ten-year terms from the grant date and vested in three equal annual installments, which began on their respective grant dates.

	Employee Share Purchase and Deferred Share Plan
	The Acadia Realty Trust Employee Share Purchase Plan (the "Purchase Plan"), allows eligible employees of the Company to purchase Common Shares through payroll deductions. The Purchase Plan provides for employees to purchase Common Shares on a quarterly basis at a 15% discount to the closing price of the Company’s Common Shares on either the first day or the last day of the quarter, whichever is lower. A participant may not purchase more the $25,000 in Common Shares per year. Compensation expense will be recognized by the Company to the extent of the above discount to the closing price of the Common Shares with respect to the applicable quarter. During 2013, 2012 and 2011, a total of 3,678, 3,829, and 4,886 Common Shares, respectively, were purchased by employees under the Purchase Plan. Associated compensation expense of $0.01 million was recorded in 2013, 2012 and 2011.
	During May of 2006, the Company adopted a Trustee Deferral and Distribution Election ("Trustee Deferral Plan"), under which the participating Trustees have deferred compensation of $0.07 million for 2013 and $0.06 million for 2012 and 2011.

	The Company has elected to qualify as a REIT in accordance with Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the "Code"), and intends at all times to qualify as a REIT under the Code. 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 annual REIT taxable income to its shareholders. As a REIT, the Company generally will not be subject to corporate Federal income tax, provided that distributions to its shareholders equal at least the amount of its REIT taxable income as defined under the Code. As the Company distributed sufficient taxable income for the years ended December 31, 2013, 2012 and 2011, no U.S. Federal income or excise taxes were incurred. If the Company fails to qualify as a REIT in any taxable year, it will be subject to Federal income taxes at the regular corporate rates (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for the four subsequent taxable years. Even though the Company qualifies for taxation as a REIT, the Company is subject to certain state and local taxes on its income and property and Federal income and excise taxes on any undistributed taxable income. In addition, taxable income from non-REIT activities managed through the Company’s Taxable REIT Subsidiaries ("TRS") is subject to Federal, state and local income taxes.
	Characterization of Distributions:
	The Company has determined that the cash distributed to the shareholders is characterized as follows for Federal income tax purposes:
		For the years ended December 31,

Earnings Per Share [Abstract]	'
Earnings Per Common Share	'
	Earnings Per Common Share
	Basic earnings per Common Share is computed by dividing net income attributable to Common Shareholders by the weighted average Common Shares outstanding. At December 31, 2013, the Company has unvested LTIP Units (Note 15) which provide for non-forfeitable rights to dividend equivalent payments. Accordingly, these unvested LTIP Units are considered participating securities and are included in the computation of basic earnings per Common Share pursuant to the two-class method.
	Diluted earnings per Common Share reflects the potential dilution of the conversion of obligations and the assumed exercises of securities including the effects of restricted share unit ("Restricted Share Units") and share option awards issued under the Company’s Share Incentive Plans (Note 15). The effect of the assumed conversion of 188 Series A Preferred OP Units into 25,067 Common Shares would be anti-dilutive and therefore not included in the computation of diluted earnings per share for the years ended December 2013, 2012 and 2011.
	The effect of the conversion of Common OP Units is not reflected in the computation of basic and diluted earnings per share, as they are exchangeable for Common Shares on a one-for-one basis. The income allocable to such units is allocated on this same basis and reflected as noncontrolling interests in the accompanying consolidated financial statements. As such, the assumed conversion of these units would have no net impact on the determination of diluted earnings per share. The conversion of the convertible notes payable (Note 9) is not included in the computation of basic and diluted earnings per share as such conversion, based on the current market price of the Common Shares, would be settled with cash.

	Commitments and Contingencies
	Under various Federal, state and local laws, ordinances and regulations relating to the protection of the environment, a current or previous owner or operator of real estate may be liable for the cost of removal or remediation of certain hazardous or toxic substances disposed, stored, generated, released, manufactured or discharged from, on, at, under, or in a property. As such, the Company may be potentially liable for costs associated with any potential environmental remediation at any of its formerly or currently owned properties.
	The Company conducts Phase I environmental reviews with respect to properties it acquires. These reviews include an investigation for the presence of asbestos, underground storage tanks and polychlorinated biphenyls (PCBs). Although such reviews are intended to evaluate the environmental condition of the subject property as well as surrounding properties, there can be no assurance that the review conducted by the Company will be adequate to identify environmental or other problems that may exist. Where a Phase II assessment is so recommended, a Phase II assessment is conducted to further determine the extent of possible environmental contamination. In all instances where a Phase I or II assessment has resulted in specific recommendations for remedial actions, the Company has either taken or scheduled the recommended remedial action. To mitigate unknown risks, the Company has obtained environmental insurance for most of its properties, which covers only unknown environmental risks.
	The Company believes that it is in compliance in all material respects with all Federal, state and local ordinances and regulations regarding hazardous or toxic substances. Management is not aware of any environmental liability that it believes would have a material adverse impact on the Company’s financial position or results of operations. Management is unaware of any instances in which the Company would incur significant environmental costs if any or all properties were sold, disposed of or abandoned. However, there can be no assurance that any such non-compliance, liability, claim or expenditure will not arise in the future.
	The Company is involved in various matters of litigation arising in the normal course of business. While the Company is unable to predict with certainty the amounts involved, the Company’s management and counsel are of the opinion that, when such litigation is resolved, the Company’s resulting liability, if any, will not have a significant effect on the Company’s consolidated financial position, results of operations, or liquidity. The Company's policy is to accrue legal expenses as they are incurred.
	During August 2009, the Company terminated the employment of a former Senior Vice President (the "Former Employee") for engaging in conduct that fell within the definition of "cause" in his severance agreement with the Company. Had the Former Employee not been terminated for "cause," he would have been eligible to receive approximately $0.9 million under the severance agreement. Because the Company terminated him for "cause," it did not pay the Former Employee any severance benefits under the agreement. The Former Employee has brought a lawsuit against the Company in New York State Supreme Court (the "Court"), alleging breach of the severance agreement. Depositions have been completed and a trial date has been set. The Court has granted the Company's request to file a motion for summary judgment. The suit is in the pre-trial discovery stage. The Company believes it has meritorious defenses to the suit.
	In connection with Phase 2 of the City Point Project, Albee Development LLC ("Albee"), and a non-affiliated construction manager have been served with a Summons With Notice by Casino Development Group, Inc. ("Casino"), the former contractor responsible for the excavation and concrete work at the City Point Project. Albee terminated the contract with Casino for cause prior to completion of the contract. The plaintiff is seeking approximately $8.5 million. Albee believes that it has meritorious defenses to, and is prepared to vigorously defend itself against the claims. As the case is in the beginning stage of litigation, the outcome of these claims cannot be estimated at this time.

ORGANIZATION, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2013
Organization, Basis of Presentation and Summary of Significant Accounting Policies [Abstract]	'
Consolidation, Policy [Policy Text Block]	'
	Principles of Consolidation
	The consolidated financial statements include the consolidated accounts of the Company and its controlling investments in partnerships and limited liability companies in which the Company has control in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 810 "Consolidation" ("ASC Topic 810"). The ownership interests of other investors in these entities are recorded as noncontrolling interests. All significant intercompany balances and transactions have been eliminated in consolidation. Investments in entities for which the Company has the ability to exercise significant influence over, but does not have financial or operating control, are accounted for using the equity method of accounting. Accordingly, the Company’s share of the earnings (or losses) of these entities are included in consolidated net income.
	Variable interest entities are accounted for within the scope of ASC Topic 810 and are required to be consolidated by their primary beneficiary. The primary beneficiary of a variable interest entity is the enterprise that has the power to direct the activities that most significantly impact the variable interest entity’s economic performance and the obligation to absorb losses or the right to receive benefits of the variable interest entity that could be significant to the variable interest entity. Management has evaluated the applicability of ASC Topic 810 to its investments in certain joint ventures and determined that these joint ventures are not variable interest entities or that the Company is not the primary beneficiary and, therefore, consolidation of these ventures is not required. These investments are accounted for using the equity method of accounting.
Investments in and Advances to Unconsolidated Joint Ventures, Policy [Policy Text Block]	'
	Investments in and Advances to Unconsolidated Joint Ventures
	The Company primarily accounts for its investments in unconsolidated joint ventures using the equity method as it does not exercise control over significant asset decisions such as buying, selling or financing nor is it the primary beneficiary under ASC Topic 810, as discussed above in most of these investments. The Company does have significant influence over most of these investments, which requires equity method accounting. Under the equity method, the Company increases its investment for its proportionate share of net income and contributions to the joint venture and decreases its investment balance by recording its proportionate share of net loss and distributions. The Company accounts for some of its investments under the cost method. Due to its minor ownership of three investments as well as the terms of the underlying operating agreements, the Company has no influence over such entities' operating and financial policies. Other than the minority investor rights to which the Company is entitled pursuant to statute, it has no rights other than to receive its pro-rata share of cash distributions as declared by the managers of these investments. The Company has no rights with respect to the control and operation of these investments vehicles, nor with the formulation and execution of business and investment policies. The Company recognizes income for distributions in excess of its investment where there is no recourse to the Company. For investments in which there is recourse to the Company, distributions in excess of the investment are recorded as a liability. Although the Company accounts for its investment in Albertson’s (Note 4) under the equity method of accounting, the Company adopted the policy of not recording its equity in earnings or losses of this unconsolidated affiliate until it receives the audited financial statements of Albertson’s to support the equity earnings or losses in accordance with ASC Topic 323, "Investments – Equity Method and Joint Ventures."
	ACADIA REALTY TRUST AND SUBSIDIARIES
	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
	1. Organization, Basis of Presentation and Summary of Significant Accounting Policies, continued
	The Company periodically reviews its investment in unconsolidated joint ventures for other-than-temporary losses in investment value. Any decline that is not expected to be recovered is considered other than temporary and an impairment charge is recorded as a reduction in the carrying value of the investment. During 2012, the Company recorded an impairment charge of $2.0 million in connection with the estimated fair value in its investment in Mervyns. During the years ended December 31, 2013 and 2011, there were no impairment charges related to the Company’s investment in unconsolidated joint ventures.
Use of Estimates, Policy [Policy Text Block]	'
	Use of Estimates
	Accounting principles generally accepted in the United States of America ("GAAP") require the Company’s management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The most significant assumptions and estimates relate to the valuation of real estate, depreciable lives, revenue recognition and the collectability of notes receivable and rents receivable. Application of these estimates and assumptions requires the exercise of judgment as to future uncertainties and, as a result, actual results could differ from these estimates.
Real Estate, Policy [Policy Text Block]	'
	Real Estate
	Real estate assets are stated at cost less accumulated depreciation. Construction in progress includes costs for significant property expansion and redevelopment. Depreciation is computed on the straight-line basis over estimated useful lives of 30 to 40 years for buildings, the shorter of the useful life or lease term for tenant improvements and five years for furniture, fixtures and equipment. Expenditures for maintenance and repairs are charged to operations as incurred.
	Upon acquisitions of real estate, the Company assesses the fair value of acquired assets and assumed liabilities (including land, buildings and improvements, and identified intangibles such as above and below market leases and acquired in-place leases and customer relationships) and acquired liabilities in accordance with ASC Topic 805 "Business Combinations" and ASC Topic 350 "Intangibles – Goodwill and Other," and allocates the acquisition price based on these assessments. Fixed-rate renewal options have been included in the calculation of the fair value of acquired leases where applicable. To the extent there were fixed-rate options at below-market rental rates, the Company included these along with the current term below-market rent in arriving at the fair value of the acquired leases. The discounted difference between contract and market rents is being amortized over the remaining applicable lease term, inclusive of any option periods. The Company assesses fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends, and market/economic conditions that may affect the property.
	The Company capitalizes certain costs related to the development and redevelopment of real estate including pre-construction costs, interest, real estate taxes, insurance, construction costs and salaries and related costs of personnel directly involved with the specific project. Additionally, the Company capitalizes interest costs related to development and redevelopment activities. Capitalization of these costs begin when the activities and related expenditures commence, and cease when the property is held available for occupancy upon substantial completion of tenant improvements, but no later than one year from the completion of major construction activity at which time the project is placed in service and depreciation commences.
	The Company reviews its long-lived assets for impairment when there is an event or a change in circumstances that indicates that the carrying amount may not be recoverable. The Company measures and records impairment losses and reduces the carrying value of properties when indicators of impairment are present and the expected undiscounted cash flows related to those properties are less than their carrying amounts. In cases where the Company does not expect to recover its carrying costs on properties held for use, the Company reduces its carrying costs to fair value, and for properties held for sale, the Company reduces its carrying value to the fair value less costs to sell. During the year ended December 31, 2013, the Company determined that the values of the Walnut Hill Plaza and Fund III's Sheepshead Bay property were impaired. Accordingly, impairment charges of $1.5 million and $6.7 million, respectively were recorded. The Operating Partnership's share of the impairment charge related to Sheepshead Bay was $1.3 million. During the year ended December 31, 2011, the Company determined that the value of the Granville Centre owned by Fund I was impaired. Accordingly, an impairment loss of $6.9 million was recorded, of which the Operating Partnership's share was $1.5 million. During the year ended December 31, 2012, no impairment charges were recorded. Management does not believe that the values of any other properties within the portfolio are impaired as of December 31, 2013.
Sale of Real Estate, Policy [Policy Text Block]	'
	The Company recognizes property sales in accordance with ASC Topic 970 "Real Estate." The Company generally records the sales of operating properties and outparcels using the full accrual method at closing when the earnings process is deemed to be complete. Sales not qualifying for full recognition at the time of sale are accounted for under other appropriate deferral methods.
Real Estate Held for Development and Sale, Policy [Policy Text Block]	'
	The Company evaluates the held-for-sale classification of its real estate each quarter. Assets that are classified as held for sale are recorded at the lower of their carrying amount or fair value less cost to sell. Assets are generally classified as held for sale once management has initiated an active program to market them for sale and has received a firm purchase commitment. The results of operations of these real estate properties are reflected as discontinued operations in all periods presented.
	On occasion, the Company will receive unsolicited offers from third parties to buy individual Company properties. Under these circumstances, the Company will classify the properties as held for sale when a sales contract is executed with no contingencies and the prospective buyer has funds at risk to ensure performance.
Involuntary Conversion of Asset, Policy [Policy Text Block]	'
	Involuntary Conversion of Asset
	The Company experienced significant flooding resulting in extensive damage to one of its properties during September 2011. Costs related to the clean-up and redevelopment were insured for an amount sufficient that would allow for full restoration of the property. Loss of rents during the redevelopment were covered by business interruption insurance subject to a $0.1 million deductible.
	In accordance with ASC Topic 360 "Property, Plant and Equipment" and as a result of the above-described property damage, the Company had recorded a write-down of the asset's carrying value of approximately $1.4 million, as well as an insurance recovery in the same amount that is included in Prepaid Expenses and Other Assets in the accompanying consolidated balance sheets as of December 31, 2011. The Company also provided a $0.1 million provision in the 2011 consolidated statement of income for its exposure to the insurance deductible attributable to the loss of rents. During the years ended December 31, 2012 and 2011, the Company received insurance proceeds of approximately $3.7 million and $6.9 million, respectively. The Company recognized a gain on involuntary conversion of $2.4 million in 2012 as these proceeds exceeded the asset's net basis.
Deferred Costs, Policy [Policy Text Block]	'
	Deferred Costs
	Fees and costs paid in the successful negotiation of leases are deferred and amortized on a straight-line basis over the terms of the respective leases. Fees and costs incurred in connection with obtaining financing are deferred and amortized over the term of the related debt obligation. The Company capitalizes salaries, commissions and benefits related to time spent by leasing and legal department personnel involved in originating leases.
Management Contracts, Policy [Policy Text Block]	'
	Management Contracts
	Income from management contracts is recognized on an accrual basis as such fees are earned. The initial acquisition costs of any management contracts are amortized over the estimated lives of the contracts acquired.
Revenue Recognition and Accounts Receivable, Policy [Policy Text Block]	'
	Revenue Recognition and Accounts Receivable
	Leases with tenants are accounted for as operating leases. Minimum rents are recognized, net of any rent concessions or tenant lease incentives, including free rent, on a straight-line basis over the term of the respective leases, beginning when the tenant is entitled to take possession of the space. As of December 31, 2013 and 2012, unbilled rents receivable relating to the straight-lining of rents of $23.1 million and $23.6 million, respectively are included in Rents Receivable, net on the accompanying consolidated balance sheets. Certain of these leases also provide for percentage rents based upon the level of sales achieved by the tenant. Percentage rent is recognized in the period when the tenants’ sales breakpoint is met. In addition, leases typically provide for the reimbursement to the Company of real estate taxes, insurance and other property operating expenses. These reimbursements are recognized as revenue in the period the related expenses are incurred.

	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
	1. Organization, Basis of Presentation and Summary of Significant Accounting Policies, continued
	The Company makes estimates of the uncollectability of its accounts receivable related to tenant revenues. An allowance for doubtful accounts has been provided against certain tenant accounts receivable that are estimated to be uncollectible. Once the amount is ultimately deemed to be uncollectible, it is written off. Rents receivable at December 31, 2013 and 2012 are shown net of an allowance for doubtful accounts of $6.0 million and $6.1 million, respectively.
Notes Receivable and Preferred Equity Investments, Policy [Policy Text Block]	'
	Notes Receivable and Preferred Equity
	Notes receivable and preferred equity investments are intended to be held to maturity and are carried at amortized cost. Interest income from notes receivable and preferred equity investments are recognized on the effective interest method over the expected life of the loan. Under the effective interest method, interest or fees collected at the origination of the investment or the payoff of the investment are recognized over the term of the loan as an adjustment to yield.
	Allowances for real estate notes receivable are established based upon management’s quarterly review of the investments. In performing this review, management considers the estimated net recoverable value of the loan as well as other factors, including the fair value of any collateral, the amount and status of any senior debt, and the prospects for the borrower. Because this determination is based upon projections of future economic events, which are inherently subjective, the amounts ultimately realized from the loans may differ materially from their carrying values at the balance sheet date. Interest income recognition is generally suspended for loans when, in the opinion of management, a full recovery of income and principal becomes doubtful. Income recognition is resumed when the suspended loan becomes contractually current and performance is demonstrated to be resumed.
	During 2012, the Company provided a $0.4 million net reserve on note receivables as a result of changes in the value of the underlying collateral properties.
Cash and Cash Equivalents, Policy [Policy Text Block]	'
	Cash and Cash Equivalents
	The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents are maintained at financial institutions and, at times, balances may exceed the federally insured limit by the Federal Deposit Insurance Corporation. The Company has never experienced any losses related to these balances.
Restricted Cash and Cash in Escrow, Policy [Policy Text Block]	'
	Restricted Cash and Cash in Escrow
	Restricted cash and cash in escrow consist principally of cash held for real estate taxes, construction costs, property maintenance, insurance, minimum occupancy and property operating income requirements at specific properties as required by certain loan agreements.
Income Tax, Policy [Policy Text Block]	'
	Income Taxes
	The Company has made an election to be taxed, and believes it qualifies, as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the "Code"). To maintain REIT status for Federal income tax purposes, the Company is generally required to distribute at least 90% of its REIT taxable income to its shareholders as well as comply with certain other income, asset and organizational requirements as defined in the Code. Accordingly, the Company is generally not subject to Federal corporate income tax to the extent that it distributes 100% of its REIT taxable income each year.
	Although it may qualify for REIT status for Federal income tax purposes, the Company is subject to state income or franchise taxes in certain states in which some of its properties are located. In addition, taxable income from non-REIT activities managed through the Company’s taxable REIT subsidiaries ("TRS") is fully subject to Federal, state and local income taxes.
	The Company accounts for TRS income taxes under the liability method as required by ASC Topic 740, "Income Taxes." Under the liability method, deferred income taxes are recognized for the temporary differences between the GAAP basis and tax basis of the TRS income, assets and liabilities.
	ACADIA REALTY TRUST AND SUBSIDIARIES
	NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
	1. Organization, Basis of Presentation and Summary of Significant Accounting Policies, continued
	In accordance with ASC Topic 740, the Company believes that it has appropriate support for the income tax positions taken and, as such, does not have any uncertain tax positions that, if successfully challenged, could result in a material impact on the Company's financial position or results of operation. The prior three years' income tax returns are subject to review by the Internal Revenue Service. The Company recognizes potential interest and penalties related to uncertain tax positions as a component of the provision for income taxes.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	'
	Stock-based Compensation
	The Company accounts for stock-based compensation pursuant to ASC Topic 718, "Compensation – Stock Compensation." As such, all equity based awards are reflected as compensation expense in the Company’s consolidated financial statements over their vesting period based on the fair value at the date of grant.
Recent Accounting Pronouncements, Policy [Policy Text Block]	'
	Recent Accounting Pronouncements
	During July 2013, the FASB issued Accounting Standards Update ("ASU") No. 2013-11, "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists." ASU 2013-11 requires an entity to present an unrecognized tax benefit relating to a net operating loss carryforward, a similar tax loss or a tax credit carryforward as a reduction to a deferred tax asset except in certain situations. To the extent the net operating loss carry forward, similar tax loss or tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of the tax position or the tax law of the applicable jurisdiction does not require the entity to use and the entity does not intend to use the deferred tax asset for such purpose, the unrecognized tax benefit should be presented as a liability. ASU No. 2013-11 is effective for fiscal years, and interim periods within those years, beginning on or after December 15, 2013. The adoption of ASU No. 2013-11 is not expected to have a material impact on the Company's financial condition or results of operations.
	During February 2013, the FASB issued Accounting Standards Update ("ASU") No. 2013-03, "Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income." ASU 2013-03 requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. ASU is effective prospectively for reporting periods beginning after December 15, 2012. The adoption of ASU 2013-03 did not have a material impact on the Company's financial condition or results of operations.
