Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Organization	Business and Organization The Company is a REIT that focuses on owning and operating income producing retail properties with a primary focus on grocery-anchored shopping centers primarily in the Northeast. At December 31, 2023, the Company owned a portfolio of 19 properties. Seven of these properties are located in Pennsylvania, four in Massachusetts, three in Connecticut, three in New Jersey, one in Maryland and one in Virginia. The Company, organized as a Maryland corporation, has established an umbrella partnership structure through the contribution of substantially all of its assets to the Operating Partnership, organized as a limited partnership under the laws of Delaware. The Operating Partnership is the entity through which the Company conducts substantially all of its business and owns (either directly or through subsidiaries) substantially all of its assets. At December 31, 2023, the Company, which is a subsidiary of WHLR, owned a 100.0% interest in, and was the sole general partner of, the Operating Partnership. As used herein, the "Company" refers to Cedar Realty Trust, Inc. and its subsidiaries on a consolidated basis, including the Operating Partnership or, where the context so requires, Cedar Realty Trust, Inc. only. Asset Sale and Merger On March 2, 2022, the Company entered into definitive agreements for the sale of the Company and its assets in a series of related all-cash transactions. Specifically, the Company and certain of its subsidiaries entered into the Asset Purchase Agreement with the Grocery-Anchored Purchasers for the sale of a portfolio of 33 grocery-anchored shopping centers for cash. In addition, the Company entered into the Merger Agreement with WHLR and certain of its affiliates pursuant to which, following closing of the Grocery-Anchored Portfolio Sale, WHLR acquired the balance of the Company's shopping center assets by way of an all-cash merger transaction. The Transactions were unanimously approved by the Company's former Board of Directors and were approved by the Company's common stockholders at a special meeting of stockholders held on May 27, 2022. On July 7, 2022, the Company and certain of its subsidiaries completed the Grocery-Anchored Portfolio Sale and the East River Park and Senator Square redevelopment asset sales for total gross proceeds of approximately $879 million, including the assumed debt. There were no material relationships among the Company, the Grocery-Anchored Purchasers, or any of their respective affiliates. On August 22, 2022, the Company completed the Merger. Each outstanding share of common stock of the Company and outstanding common unit of the Operating Partnership held by persons other than the Company immediately prior to the Merger were canceled and converted into the right to receive a cash payment of $9.48 per share or unit. As a result of the Merger, WHLR acquired all of the outstanding shares of the Company's common stock, which ceased to be publicly traded on the NYSE. The Company's outstanding 7.25% Series B Preferred Stock and 6.50% Series C Preferred Stock remain outstanding and continue to trade on the NYSE. In addition, prior to consummation of the Merger, the Company's Board of Directors declared a special dividend on shares of the Company's outstanding common stock and OP Units of $19.52 per share, payable to holders of record of the Company's common stock and OP Units at the close of business on August 19, 2022. In connection with the Transactions, the Company incurred transaction costs of $59.0 million for the year ended December 31, 2022, included in the accompanying consolidated statement of operations, of which $33.5 million relates to employee severance payments.
