Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation 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 of senior housing communities 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 June 30, 2024, the Company operated 78 senior housing communities in 19 states with an aggregate capacity of approximately 8,700 residents1, including 66 owned senior housing communities (4 through a joint venture investment in an unconsolidated entity) and 12 communities that the Company third-party manages. Principles of Consolidation The accompanying condensed consolidated financial statements include the financial statements of Sonida Senior Living, Inc. and its wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. 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 June 30, 2024, the Company has a joint venture, Stone JV LLC (“Stone”) that is treated as an unconsolidated entity. See “Note 3 –A cquisition and Investment s.” The Company does not have any VIEs that are consolidated. Interim Unaudited Financial Information The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2023. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been omitted from this Quarterly Report on Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The results for the interim periods shown in this report are not necessarily indicative of future financial results. The accompanying condensed consolidated financial statements have not been audited by our independent registered public accounting firm. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, including normal recurring items, necessary to present fairly our condensed consolidated financial position as of June 30, 2024 and December 31, 2023, and our condensed consolidated results of operations and cash flows for the periods ended June 30, 2024 and 2023. Reclassifications Certain amounts previously reflected in the prior year condensed consolidated financial statements have been reclassified to conform to our June 30, 2024 presentation. The condensed consolidated statements of operations for the six months ended June 30, 2023 include the reclassification of “gain on sale of assets” to “other income (expense), net.” Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. These estimates include such items related to the accounting for: income taxes, including assessments of probabilities of realization of income tax benefits; other contingencies; allowances for uncollectible accounts receivable; impairment of long-lived assets, including applicable cash flow projections, holding periods and fair value evaluations; self-insurance liabilities and expense; stock-based compensation; fair values of assets and liabilities acquired in asset acquisitions, fair values of our equity method investments; and depreciation and amortization including determination of estimated useful lives. Actual results could differ from those estimates.
