The Rent Stabilization Protection Amendment Act of 2025 aims to amend the Rental Housing Act of 1985 by removing the exemption from the Rent Stabilization Program for units rented to tenants using a tenant-based subsidy. The bill prohibits the administrator of any tenant-based subsidy from paying increased rent without proper notice that the increase complies with the Rent Stabilization Program. Additionally, it empowers the subsidy administrator to challenge inappropriate rent adjustments and ensures that reasonable rent increases can occur after a tenant voluntarily vacates a unit.

Key amendments include the addition of definitions for "subsidy administrator" and "tenant-based subsidy program," as well as provisions that require subsidy administrators to receive notice of any rent adjustments and to ensure compliance with the Rent Stabilization Program. The bill also establishes that tenants participating in tenant-based subsidy programs will have the same rights as other tenants under the D.C. Human Rights Act, and it clarifies the process for rent adjustments and challenges related to these units.
