Considering an ADU? Start Here.

Homeowners, take note: we’ve launched a new ADU How-To page to help you explore whether an Accessory Dwelling Unit (ADU) is right for you. Whether you’re interested in downsizing, creating housing for a family member, or generating rental income, the page walks through the basics of planning and building an ADU — from deciding what type works best for your property to finding contractors and exploring financing options.

The guide also includes links to free ADU concept plans from both the North Adams Partnership’s Small & Smart design challenge and the state’s new ADU initiative, along with information about local permitting considerations and low-interest financing programs available through Massachusetts.
