In 2024, Governor Maura Healey signed the Affordable Homes Act. It authorized $5.16 billion in spending over the next five years to counter rising housing costs caused by high demand and limited supply.
Section 8 of the Massachusetts Affordable Homes Act (Chapter 150 of the Acts of 2024) amended Section 3 of the Massachusetts Zoning Act. This took effect on February 2, 2025, requiring municipalities to allow ADUs (900 or fewer square feet) as of right in most single-family residential zoning districts, with some important limitations.
Massachusetts recently enacted a new housing statute that makes it easier for homeowners to create accessory dwelling units (ADUs) on their residential properties. These commonly were called “in-law apartments” but the new law allows much more.
