Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation and Employee Benefits	Stock-Based Compensation and Employee Benefits Stock-Based Compensation On October 27, 2016, the Company adopted the 2016 Equity Compensation Plan (the “Plan”), the purpose of which is to align the interests of the Company’s officers, other employees, advisors and consultants or any subsidiary, if any, with those of the Company’s shareholders and to afford an incentive to such officers, employees, consultants and advisors to continue as such, to increase their efforts on the Company’s behalf and to promote the success of the Company’s business. The Plan was administered by the Company's Compensation Committee (the "Compensation Committee"). The maximum number of the Company's common shares, par value $0.001 per share (the "Common Shares") reserved for the grant of awards under the Plan was 1,500,000, subject to adjustment as provided in Section 5 of the Plan. The number of shares issuable to any one individual in a plan year was also limited to 100,000 shares, subject to adjustment as provided for in the Plan. On July 9, 2025, the Company adopted the 2025 Omnibus Incentive Plan (the "2025 Plan"), which replaced the Plan. The purpose of the 2025 Plan is consistent with that of the Plan and the maximum number of Common Shares reserved for grant of awards under the 2025 Plan is 2,936,762. The number of securities remaining available for future issuance under the 2025 Plan as of September 30, 2025 was 2,553,447. During the nine months ended September 30, 2025 and 2024, the Company granted an aggregate of 1,150,983 and 212,857, respectively, restricted Common Shares under the 2025 Plan and the Plan. Of the 1,150,983 shares granted during the nine months ended September 30, 2025, a grant of 420,168 shares was rescinded immediately after the grant as discussed further below. On March 10, 2025, the Compensation Committee authorized (i) a grant of 420,168 restricted Common Shares to John L. Villano, which shares had a fair market value on the date of grant of approximately $0.5 million; and (ii) a one-time bonus grant of 20,000 restricted Common Shares to each of the Company’s directors other than Mr. Villano. Each of the grantees, except for Mr. Walraven, also had the option, at his or her election, to receive the fair market value equivalent of his or her grant in a lump sum cash payment of $23,800. An aggregate of 60,000 restricted Common Shares were granted to the Company’s non-employee directors, which shares had an aggregate fair market value on the date of grant of approximately $71,400. One director elected the cash option. Subsequent to the Compensation Committee's action on March 10, 2025, authorizing the issuance of 420,168 Common Shares, subject to certain restrictions, to John L. Villano under the Plan, the Company realized that the grant exceeded the 100,000 share limit on grants to any single individual in any one year set forth in the Plan by 320,168 shares. In addition, upon further investigation, the Company determined that restricted stock grants made to Mr. Villano with respect to calendar years 2023 and 2024, exceeded the Plan's 100,000 share limit by 30,890 and 11,857 shares, respectively. Thus, in the aggregate, 362,915 restricted shares were issued in excess of Plan limitations. All such shares were unvested and subject to restriction. In an immediate full and in excess of necessary remediation of this matter, on March 24, 2025, the Compensation Committee rescinded the March 10, 2025 award to Mr. Villano ab initio. No other over issuances have been identified and no applicable adjustment have been identified. Stock-based compensation for the three and nine months ended September 30, 2025 was $0.2 million and $0.6 million, respectively. Stock-based compensation for the three and nine months ended September 30, 2024 was $0.2 million and $0.7 million, respectively. As of September 30, 2025, there was unrecognized stock-based compensation expense of $0.9 million. Employee Benefits On April 16, 2018, the Company’s Board of Directors approved the adoption of the Sachem Capital Corp. 401(k) Profit Sharing Plan (the “401(k) Plan”). All employees, who meet the participation criteria, are eligible to participate in the 401(k) Plan. Under the terms of the 401(k) Plan, the Company is obligated to contribute 3% of a participant’s compensation to the 401(k) Plan on behalf of an employee-participant. For the three and nine months ended September 30, 2025, the 401(k) Plan expense was $27,156 and $87,304, respectively, and for the three and nine months ended September 30, 2024, the 401(k) Plan expense was $24,762 and $100,223, respectively, which is included within compensation and employee benefits in the accompanying Condensed Consolidated Statements of Operations.
