This bill directs municipalities served by commuter rail, subway, and regional bus rapid transit to establish reasonable zoning for multifamily, mixed-income housing near transit stations, while providing state grants and technical assistance for communities that meet production and affordability targets. A portion of units supported by state funds shall remain affordable to low- and moderate-income households, and the bill strengthens tenant protections by requiring advance notice of lease nonrenewal, relocation assistance for qualifying no-fault displacement, and clear enforcement of existing housing standards.
