Thinking about adding an Accessory Dwelling Unit (ADU) to your property? 🏠 Since the 2024 Massachusetts Affordable Homes Act, homeowners can now build one ADU on their lot—creating flexible space for family, guests, rental income, or long‑term value.
WHAT'S AN ADU?
A small secondary dwelling on the same property as your main home. ADUs can be attached (like a converted basement, garage, or addition) or detached (like a standalone tiny home).
STATE & REGIONAL SUPPORT
Both the state and the Berkshire Regional Planning Commission have moved toward clearer, more flexible rules that make ADUs easier to build and integrate into single‑family neighborhoods.
TIME & COST
ADUs generally take 4–10 months to build once construction begins. Costs depend on size, materials, and site conditions, since every ADU is fully customized.
