Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business	Organization and Business Sonida Senior Living, Inc., a Delaware corporation (together with its subsidiaries, the “Company,” “we,” “our,” “us,” or “Sonida”), is a leading owner, operator and investor in independent living, assisted living and memory care communities and services for senior adults in the United States in terms of resident capacity. The Company owns, operates, manages and invests in senior housing communities throughout the United States. As of December 31, 2025, the Company owned, managed or invested in 96 senior housing communities in 20 states with an aggregate capacity of approximately 10,150 residents1, including 84 owned senior housing communities (inclusive of four owned through joint venture investments in consolidated entities and four owned through a joint venture investment in an unconsolidated entity) and 12 communities that the Company managed on behalf of a third-party. Principles of Consolidation The accompanying consolidated financial statements include the financial statements of Sonida Senior Living, Inc., its wholly-owned subsidiaries, and other entities in which the Company has a controlling financial interest. All material intercompany balances and transactions have been eliminated in consolidation and net income (loss) is reduced by the portion of net income (loss) attributable to noncontrolling interests. The Company reports investments in unconsolidated entities over whose operating and financial policies it has the ability to exercise significant influence under the equity method of accounting. The Company evaluates its potential variable interest entity (“VIE”) relationships under certain criteria as provided for in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, Consolidation (“ASC 810”). ASC 810 broadly defines a VIE as an entity with one or more of the following characteristics: (a) the total equity investment at risk is insufficient to finance the entity's activities without additional subordinated financial support; (b) as a group, the holders of the equity investment at risk lack (i) the ability to make decisions about the entity's activities through voting or similar rights, (ii) the obligation to absorb the expected losses of the entity, or (iii) the right to receive the expected residual returns of the entity; or (c) the equity investors have voting rights that are not proportional to their economic interests, and substantially all of the entity's activities either involve, or are conducted on behalf of, an investor that has disproportionately few voting rights. The Company performs this evaluation on an ongoing basis and consolidates any VIEs for which the Company is determined to be the primary beneficiary, as determined by the Company's power to direct the VIEs activities and the obligation to absorb its losses or the right to receive its benefits, which are potentially significant to the VIE. As of December 31, 2025 and 2024, the Company has a joint venture, Stone JV LLC (“Stone JV”) which is treated as an unconsolidated entity. See “Note 4 –Investments, Acquisitions and Assets Held for Sale.” As of December 31, 2025, the Company is a 51% owner in two joint ventures (collectively, the “Palatine JVs”) with affiliates of Palatine Capital Partners. The Company has evaluated its investment in the Palatine JVs under ASC 810. The Company has determined that it has the power to direct the activities of the VIE that most significantly impact its economic performance and is the primary beneficiary of the VIE in accordance with ASC 810. Accordingly, the Company has consolidated the activity of the Palatine JVs into its consolidated financial statements for the periods ended December 31, 2025 and 2024. See “Note 4 –Investments, Acquisitions and Assets Held for Sale.”
