The On-Site Services Act of 2025 establishes the On-Site Services Program, which aims to provide funding to qualifying housing providers for the delivery of on-site services to residents. The program is overseen by the Department of Human Services (DHS) and will be administered by a nonprofit organization selected by DHS. Qualifying housing providers must meet specific criteria, including having at least 20 dwelling units and a minimum occupancy of 30% by recipients of permanent housing subsidies. The funding provided through the program is capped at $2,000 per unit or $200,000, whichever is lower, and must be used exclusively for on-site services or related administrative costs.

The bill also outlines application requirements for housing providers, including demonstrating resident support for proposed services and ensuring that service providers have the necessary qualifications. Additionally, it mandates annual progress reports from grant recipients to track the effectiveness of the services provided. The Mayor is granted rulemaking authority to implement the program, and the act will take effect following the approval process, including a fiscal impact certification. The legislation emphasizes resident rights, ensuring participation in services is voluntary and protecting residents' information from being shared without consent.
