Accounting Policies [Abstract]
Nature of Operations	Nature of Operations Pennsylvania Real Estate Investment Trust (“PREIT” or the “Company”) prepared the accompanying unaudited consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations, although we believe that the included disclosures are adequate to make the information presented not misleading. Our unaudited consolidated financial statements should be read in conjunction with the audited financial statements and the notes thereto included in PREIT’s Annual Report on Form 10-K for the year ended December 31, 2019. In our opinion, all adjustments, consisting only of normal recurring adjustments, necessary to present fairly our consolidated financial position, the consolidated results of our operations, consolidated statements of comprehensive income (loss), consolidated statements of equity and our consolidated statements of cash flows are included. The results of operations for the interim periods presented are not necessarily indicative of the results for the full year. PREIT, a Pennsylvania business trust founded in 1960 and one of the first equity real estate investment trusts (“REITs”) in the United States, has a primary investment focus on retail shopping malls located in the eastern half of the United States, primarily in the Mid-Atlantic region. As of March 31, 2020, our portfolio consists of a total of 26 properties operating in nine states, including 21 shopping malls, four other retail properties and one development property. The property in our portfolio that is classified as under development does not currently have any activity occurring. We hold our interest in our portfolio of properties through our operating partnership, PREIT Associates, L.P. (“PREIT Associates” or the “Operating Partnership”). We are the sole general partner of the Operating Partnership and, as of March 31, 2020, we held a 97.5% controlling interest in the Operating Partnership (after the redemption of 6,250,000 OP Units (as defined below) during the first quarter of 2019, which is discussed in more detail in Note 5), and consolidated it for reporting purposes. The presentation of consolidated financial statements does not itself imply that the assets of any consolidated entity (including any special-purpose entity formed for a particular project) are available to pay the liabilities of any other consolidated entity, or that the liabilities of any consolidated entity (including any special-purpose entity formed for a particular project) are obligations of any other consolidated entity. Pursuant to the terms of the partnership agreement of the Operating Partnership, each of the limited partners has the right to redeem such partner’s units of limited partnership interest in the Operating Partnership (“OP Units”) for cash or, at our election, we may acquire such OP Units in exchange for our common shares on a one-for-one basis, in some cases beginning one year following the respective issue dates of the OP Units and in other cases immediately. If all of the outstanding OP Units held by limited partners had been redeemed for cash as of March 31, 2020, the total amount that would have been distributed would have been $1.8 million, which is calculated using our March 31, 2020 closing price on the New York Stock Exchange of $0.91 per share multiplied by the number of outstanding OP Units held by limited partners, which was 2,022,635 as of March 31, 2020. We provide management, leasing and real estate development services through two of our subsidiaries: PREIT Services, LLC (“PREIT Services”), which generally develops and manages properties that we consolidate for financial reporting purposes, and PREIT-RUBIN, Inc. (“PRI”), which generally develops and manages properties that we do not consolidate for financial reporting purposes, including properties owned by partnerships in which we own an interest and properties that are owned by third parties in which we do not have an interest. PREIT Services and PRI are consolidated. PRI is a taxable REIT subsidiary, as defined by federal tax laws, which means that it is able to offer an expanded menu of services to tenants without jeopardizing our continuing qualification as a REIT under federal tax law. We evaluate operating results and allocate resources on a property-by-property basis, and do not distinguish or evaluate our consolidated operations on a geographic basis. Due to the nature of our operating properties, which involve retail shopping, we have concluded that our individual properties have similar economic characteristics and meet all other aggregation criteria. Accordingly, we have aggregated our individual properties into one reportable segment. In addition, no single tenant accounts for 10% or more of consolidated revenue, and none of our properties are located outside the United States.
COVID-19 Related Risks and Uncertainties	COVID-19 Related Risks and Uncertainties The 2020 global outbreak of a novel coronavirus (COVID-19) has adversely impacted, and will likely continue to impact, our business, financial condition, liquidity and operating results, as well as our tenants’ businesses. The continued spread of COVID-19 has also led to unprecedented global economic disruption and volatility in financial markets. We anticipate that our future business, financial condition, liquidity and results of operations, including our results for 2020 and potentially thereafter, will be materially impacted by the COVID-19 pandemic. It remains highly uncertain how long the global pandemic, economic challenges and restrictions on day-to-day life will last. Given the unprecedented and rapidly evolving developments, we cannot reasonably predict or estimate its ultimate impact on us or our tenants, or on our ability or the ability of our tenants to resume more normal operations. COVID-19 impacted our properties and caused the closures of all our properties with the first closure occurring on March 12, 2020. The first property reopening occurred in late April 2020 while others remain closed until individual states’ stay at home orders are lifted. Since most of the closures occurred in the second half of March 2020, the impact of the closures on our first quarter 2020 financial results was not significant. Ultimately, the significance of COVID-19 on our business remains highly uncertain and will depend on, among other things, the extent and duration of the pandemic, the severity of the disease and the number of people infected with the virus, the effects on the economy of the pandemic and of the measures taken by governmental authorities and other third parties restricting daily activities and the length of time that such measures remain in place, and implementation of governmental programs to assist businesses and consumers impacted by the COVID-19 pandemic.
Going Concern Considerations	Going Concern Considerations Under the accounting guidance related to the presentation of financial statements, when preparing financial statements for each annual and interim reporting period, management has the responsibility to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The financial statements do not include any adjustments that might be necessary should the Company be unable to continue as a going concern. As a result of the considerations articulated below, we believe there is substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. In applying the accounting guidance, management considered our current financial condition and liquidity sources, including current funds available, forecasted future cash flows and our conditional and unconditional obligations due over the next twelve months. Management specifically considered the following: (i) our senior unsecured facility, which includes a revolving facility maturing in 2022 with a balance of $289.0 million as of March 31, 2020 and term loans maturing in 2023 with a balance of $550.0 million as of March 31, 2020; (ii) our mortgage loans with varying maturities through 2025 with a principal balance of $896.5 million as of March 31, 2020; (iii) the financial covenant compliance requirements of our credit agreements; and (iv) recurring costs of operating our business. On March 30, 2020, the Company amended its 2014 7-Year Term Loan and 2018 Term Loan Facility to provide certain debt covenant relief through September 30, 2020. The Company anticipates not meeting certain financial covenants applicable under the credit agreements after September 30, 2020. The Company continues to work with the lender group to obtain a longer term financing solution prior to the expiration of the initial modification. However, further deterioration in our financial results due to COVID-19 could affect our covenant compliance prior to September 30, 2020. In addition, the Company plans to complete the sale-leaseback of certain properties, sell certain real estate assets and continue to control certain operational costs. Due to the inherent risks, unknown results and significant uncertainties associated with each of these matters and the direct correlation between these matters and our ability to satisfy our financial obligations that may arise over the applicable twelve month period, we are unable to conclude that it is probable that we will be able to meet our obligations arising within twelve months of the date of issuance of these financial statements under the parameters set forth in this accounting guidance. As a result, management evaluated whether this was mitigated by our approved plans and expectations for the applicable period under the second step of this accounting standard. Our ability to satisfy obligations under our senior unsecured credit facility and mortgage loans, maintain compliance with our debt covenants and fund recurring costs of operations depends primarily on management’s ability to obtain relief from the lender group in regards to debt covenants, complete the sale-leaseback of certain properties, complete the sale of certain real estate assets which will provide cash from those sales, and continue to control operational costs. While controlling operational costs are within management’s control to some extent, executing the sale-leaseback transactions, selling real estate assets, and obtaining relief from the lender group through modified debt covenant requirements involve performance by third parties and therefore cannot be considered probable of occurring.
Fair Value	Fair Value Fair value accounting applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements. Fair value measurements are determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, these accounting requirements establish a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs might include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, and are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. We utilize the fair value hierarchy in our accounting for derivatives (Level 2) and financial instruments (Level 2) and in our reviews for impairment of real estate assets (Level 3) and goodwill (Level 3).
Impairment of Assets	Impairment of Assets Real estate investments and related intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the property might not be recoverable, which is referred to as a “triggering event.” The COVID-19 impact on the economy and market conditions, together with the resulting closures of our properties, was deemed to be a triggering event as of March 31, 2020 which led to an impairment review. In connection with our review of our long-lived assets for impairment, we utilize qualitative and quantitative factors in order to estimate fair value. The significant qualitative factors that we use include age and condition of the property, market conditions in the property’s trade area, competition with other shopping centers within the property’s trade area and the creditworthiness and performance of the property’s tenants. The significant quantitative factors that we use include historical and forecasted financial and operating information relating to the property, such as net operating income, occupancy statistics, vacancy projections and tenants’ sales levels. If there is a triggering event in relation to a property to be held and used, we will estimate the aggregate future cash flows, net of estimated capital expenditures, to be generated by the property, undiscounted and without interest charges. In addition, this estimate may consider a probability weighted cash flow estimation approach when alternative courses of action to recover the carrying amount of a long-lived asset are under consideration or when a range of possible values is estimated. The determination of undiscounted cash flows requires significant estimates by our management, including the expected course of action at the balance sheet date that would lead to such cash flows. Subsequent changes in estimated undiscounted cash flows arising from changes in the anticipated action to be taken with respect to the property could affect the determination of whether an impairment exists, and the effects of such changes could materially affect our net income. If the estimated undiscounted cash flows are less than the carrying value of the property, the carrying value is written down to its fair value. Assessment of our ability to recover certain lease related costs must be made when we have a reason to believe that a tenant might not be able to perform under the terms of the lease as originally expected. This requires us to make estimates as to the recoverability of such costs. An other-than-temporary impairment of an investment in an unconsolidated joint venture is recognized when the carrying value of the investment is not considered recoverable based on evaluation of the severity and duration of the decline in value. To the extent impairment has occurred, the excess carrying value of the asset over its estimated fair value is recorded as a reduction to income. We concluded that there was no impairment as of March 31, 2020.
New Accounting Developments	New Accounting Developments Effective January 1, 2020, we adopted Accounting Standards Update (“ASU”) ASU 2016-13, Financial Instruments - Credit Losses (“ASC 326”), and subsequently issued amendments to the initial and transitional guidance within ASU 2018-19, ASU 2019-04 and ASU 2019-05. ASU 2016-13 introduced new guidance for an approach based on expected losses to estimate credit losses on certain types of financial instruments, and will affect our accounting for trade receivables and notes receivable. The adoption of this guidance did not have a material impact on our consolidated financial statements. In April 2020, the Financial Accounting Standards Board issued a Staff Question-and-Answer (“Q&A”) to clarify whether lease concessions related to the effects of COVID-19 require the application of the lease modification guidance under ASU 2016-02, Leases (Topic 842) (“ASC 842”). Under ASC 842, we would have to determine, on a lease-by-lease basis, if a lease concession was the result of a new arrangement reached with the tenant or an enforceable right and obligation within the existing lease. The Q&A allows for the bypass of a lease-by-lease analysis and for us to elect to either apply the lease modification accounting framework or not, to all of the lease concessions we make with similar characteristics and circumstances. We are continuing to assess the impact of this Q&A guidance in light of our ongoing negotiations with tenants.
Dividends Declared	Dividends Declared On May 19, 2020, we announced that our Board of Trustees declared a quarterly cash dividend of $0.02 per common share payable on June 15, 2020 to common shareholders of record on June 1, 2020. Simultaneously, our Board of Trustees also declared quarterly cash dividends of $0.4609375 per share on our 7.375% Series B Cumulative Redeemable Perpetual Preferred Shares, $0.450000 per share on our 7.20% Series C Preferred Shares, and $0.4296875 per share on our 6.875% Series D Preferred Shares. These dividends are also payable on June 15, 2020 to holders of record on June 1, 2020.

Dividends Declared

On May 19, 2020, we announced that our Board of Trustees declared a quarterly cash dividend of $0.02 per common share payable on June 15, 2020 to common shareholders of record on June 1, 2020. Simultaneously, our Board of Trustees also declared quarterly cash dividends of $0.4609375 per share on our 7.375% Series B Cumulative Redeemable Perpetual Preferred Shares, $0.450000 per share on our 7.20% Series C Preferred Shares, and $0.4296875 per share on our 6.875% Series D Preferred Shares. These dividends are also payable on June 15, 2020 to holders of record on June 1, 2020.
