Summary of Significant Accounting Policies (Policies)	Sep. 30, 2023
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Management is required to make estimates and assumptions in the preparation of financial statements in conformity with GAAP. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from management’s estimates. The consolidated financial statements include the accounts of Healthpeak Properties, Inc., its wholly-owned subsidiaries, joint ventures (“JVs”), and variable interest entities (“VIEs”) that it controls through voting rights or other means. Intercompany transactions and balances have been eliminated upon consolidation. All adjustments (consisting of normal recurring adjustments) necessary to present fairly the Company’s financial position, results of operations, and cash flows have been included. Operating results for the three and nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. The accompanying unaudited interim financial information should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 filed with the SEC.
Government Grant Income	Government Grant Income On March 27, 2020, the federal government enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) to provide financial aid to individuals, businesses, and state and local governments. During the nine months ended September 30, 2023 and the three and nine months ended September 30, 2022, the Company received government grants under the CARES Act primarily to cover increased expenses and lost revenue during the coronavirus pandemic. Grant income is recognized to the extent that qualifying expenses and lost revenues exceed grants received and the Company will comply with all conditions attached to the grant. As of September 30, 2023, the amount of qualifying expenditures and lost revenue exceeded grant income recognized and the Company believes it has complied and will continue to comply with all grant conditions. In the event of non-compliance, all such amounts received are subject to recapture.
Discontinued Operations	Discontinued Operations Senior Housing Triple-Net and Senior Housing Operating Portfolio Dispositions In 2020, the Company concluded that the dispositions of its senior housing triple-net and Senior Housing Operating Property (“SHOP”) portfolios represented a strategic shift that had a major effect on its operations and financial results. Therefore, the results of senior housing triple-net and SHOP assets are classified as discontinued operations in all periods presented herein. See Note 4 for further information.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Government Assistance. In November 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance (“ASU 2021-10”), which increased the transparency of government assistance including the disclosure of the types of assistance, an entity’s accounting for assistance, and the effect of the assistance on an entity’s financial statements. The adoption of ASU 2021-10 on January 1, 2022 did not have a material impact on the Company’s consolidated financial position, results of operations, cash flows, or disclosures. Reference Rate Reform. From March 2020 to December 2022, the FASB issued a series of ASUs that provide optional expedients that may be elected through December 31, 2024 to ease the potential burden in accounting for, or recognizing the effects of, reference rate reform on financial reporting. The amendments in these ASUs were effective immediately upon issuance. During the first quarter of 2023, the Company amended certain of its variable rate mortgage debt and the related interest rate swap agreements to change the interest rate benchmark from the London Interbank Offered Rate (“LIBOR”) to the Secured Overnight Financing Rate (“SOFR”) and accordingly, the Company elected to apply certain practical expedients provided by these ASUs related to cash flow hedges. These expedients and the effects of reference rate reform have not had a material impact on the Company’s consolidated financial position, results of operations, cash flows, or disclosures.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company maintains its cash and cash equivalents at financial institutions insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 per institution. As of September 30, 2023 and December 31, 2022, the account balances at certain institutions exceeded the FDIC insurance coverage.
