Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization and Basis of Presentation | Organization and Basis of Presentation SL Green Realty Corp., which is referred to as the Company or SL Green, a Maryland corporation, and SL Green Operating Partnership, L.P., which is referred to as SLGOP or the Operating Partnership, a Delaware limited partnership, were formed in June 1997 for the purpose of combining the commercial real estate business of S.L. Green Properties, Inc. and its affiliated partnerships and entities. The Operating Partnership received a contribution of interest in the real estate properties, as well as 95% of the economic interest in the management, leasing and construction companies which are referred to as S.L. Green Management Corp, or the Service Corporation. All of the management, leasing and construction services that are provided to the properties that are wholly-owned by us and that are provided to certain joint ventures are conducted through SL Green Management LLC and S.L. Green Management Corp., respectively, which are 100% owned by the Operating Partnership. The Company has qualified, and expects to qualify in the current fiscal year, as a real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended, or the Code, and operates as a self-administered, self-managed REIT. A REIT is a legal entity that holds real estate interests and, through payments of dividends to stockholders, is permitted to minimize the payment of Federal income taxes at the corporate level. Unless the context requires otherwise, all references to "we," "our" and "us" means the Company and all entities owned or controlled by the Company, including the Operating Partnership. Substantially all of our assets are held by, and all of our operations are conducted through, the Operating Partnership. The Company is the sole managing general partner of the Operating Partnership. As of December 31, 2023, noncontrolling investors held, in the aggregate, a 5.75% limited partnership interest in the Operating Partnership. We refer to these interests as the noncontrolling interests in the Operating Partnership. The Operating Partnership is considered a variable interest entity, or VIE, in which we are the primary beneficiary. See Note 11, "Noncontrolling Interests on the Company's Consolidated Financial Statements." On December 31, 2023, we owned the following interests in properties in the New York metropolitan area, primarily in midtown Manhattan. Our investments located outside of Manhattan are referred to as the Suburban properties:

(1)The weighted average leased occupancy for commercial properties represents the total leased square footage divided by the total square footage at acquisition. The weighted average leased for residential properties represents the total leased units divided by the total available units. Properties under construction are not included in the calculation of weighted average leased occupancy. (2)Includes assets within the Company's alternative strategy portfolio. Within that portfolio, office includes one building totaling 2,048,725 square feet, retail includes eight buildings totaling 286,738 square feet, and development/redevelopment includes two buildings totaling 1,496,931 square feet. (3)As of December 31, 2023, we owned a building at 7 Dey Street / 185 Broadway that was comprised of approximately 140,382 square feet (unaudited) of residential space and approximately 50,206 square feet (unaudited) of office and retail space that is under development. For the purpose of this report, we have included this building in the number of residential properties we own. However, we have included only the residential square footage in the residential approximate square footage, and have listed the balance of the square footage as development square footage. As of December 31, 2023, we also managed one office building and one retail building owned by a third party encompassing approximately 0.4 million square feet (unaudited), and held debt and preferred equity investments with a book value of $346.7 million, excluding debt and preferred equity investments and other financing receivables totaling $7.9 million that are included in balance sheet line items other than the Debt and preferred equity investments line item. Partnership Agreement In accordance with the partnership agreement of the Operating Partnership, or the Operating Partnership Agreement, we allocate all distributions and profits and losses in proportion to the percentage of ownership interests of the respective partners, subject to the priority distributions with respect to preferred units and special provisions that apply to Long Term Incentive Plan ("LTIP") Units. As the managing general partner of the Operating Partnership, we are required to take such reasonable efforts, as determined by us in our sole discretion, to cause the Operating Partnership to distribute sufficient amounts to enable the payment of sufficient dividends by us to minimize any Federal income or excise tax at the Company level. Under the Operating Partnership Agreement, each limited partner has the right to redeem units of limited partnership interests for cash, or if we so elect, shares of SL Green's common stock on a one-for-one basis. Subsequent Events In January 2024, the Company closed on the acquisition of interests in the joint venture that owns the leasehold interest at 2 Herald for no consideration, which increases the Company's interest in the joint venture to 95.0%. In addition, the joint venture entered into an agreement to satisfy the existing $182.5 million mortgage on the property for a net payment of $7.0 million, which closed in February 2024. See Note 6, "Investments in Unconsolidated Joint Ventures." In January 2024, together with its joint venture partner, the Company closed on the sale of the retail condominium at 717 Fifth Avenue for a total consideration of $963.0 million. See Note 6, "Investments in Unconsolidated Joint Ventures."
