Major Massachusetts housing law aims to build or save 65,000 multifamily and single-family homes

Massachusetts Gov. Maura Healey recently signed far-reaching legislation to boost housing production and address the high cost of housing in the Bay State.

The Affordable Homes Act aims to build or save 65,000 homes through $5.1 billion in spending and 49 policy initiatives. The legislation allows accessory dwelling units (ADUs) statewide, supports commercial-to-housing conversions, and provides incentives for affordable housing construction.

The act is “an unprecedented investment in modernizing the state’s public housing system,” according to a news release from the governor’s office. It also boosts programs that support first-time homebuyers and homeownership, provides incentives to build more housing for low to moderate-income residents, and supports sustainable and green housing initiatives.  

ADUs under 900 sf will be allowed by right on single-family lots. This new policy replaces a patchwork of zoning regulations across the state with a uniform law that allows homeowners on single-family lots to add these small units without needing a special permit or variance unless they want to add more than one.
