An accessory dwelling unit (“ADU”) is a small residential living space located on the same lot as another home. ADUs can be internal within an existing primary residence, like converting a basement into an apartment, attached to a primary residence as a new construction addition, or completely detached, like a cottage or converted detached garage in a backyard.
As of February 2, 2025, Massachusetts homeowners can now build Accessory Dwelling Units (ADUs) by right in single-family zoning districts, thanks to the Affordable Homes Act signed into law in August 2024. This statewide policy aims to increase housing options, support multigenerational living, and provide homeowners with opportunities for additional income.
