Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Organization and Business Sonida Senior Living, Inc., a Delaware corporation, is one of the leading owner-operators of senior housing communities in the United States in terms of resident capacity. As used herein, the “Company,” “we,” “us,” or “our” refers to Sonida Senior Living, Inc. and its subsidiaries. The Company owns, operates, develops, and manages senior housing communities throughout the United States. As of September 30, 2022, the Company operated 76 senior housing communities in 18 states with an aggregate capacity of approximately 8,000 residents, including 62 senior housing communities that the Company owned and 14 communities that the Company managed on behalf of third parties. 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. 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, 2021. 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 September 30, 2022 and December 31, 2021, and our condensed consolidated results of operations and cash flows for the periods ended September 30, 2022 and 2021. Reclassifications Certain amounts previously reflected in the prior year condensed consolidated balance sheet have been reclassified to conform to our September 30, 2022 presentation. The consolidated balance sheet as of December 31, 2021 reflects reclassifying “operating lease right-of-use assets, net” to “other assets, net”, “property tax and insurance deposits” to “restricted cash” and lender reserves from “other assets, net” to “restricted cash.” “Current portion of lease liabilities” and “customer deposits” were combined into “other current liabilities.” “Lease liabilities, net of current portion” has been reclassified as “other liabilities.” The consolidated statements of operations include the consolidation of “stock-based compensation expense” within “general and administrative expenses.” These reclassifications had no effect on the previously reported total assets or total liabilities. 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; impairment of long-lived assets, including applicable cash flow projections, holding periods and fair value evaluations; self-insurance liabilities and expense; stock-based compensation; and depreciation and amortization including determination of estimated useful lives. Actual results could differ from those estimates.
