Building an ADU by right in Bristol County.
Under the Massachusetts Affordable Homes Act (effective February 2, 2025), a single ADU of up to 900 sq ft is allowed by right in single-family zoning districts — including throughout Bristol County — with no special permit required. Standard building permits and local dimensional rules still apply, and we manage the Bristol County permitting process on your behalf.
Homeowners across Bristol County — in Freetown, Middleboro, Taunton, Wrentham, Swansea and beyond — are using ADUs to house family, generate rental income, and add long-term value. We tailor each Bristol County ADU to the lot, the existing home, and local building requirements.
ADU types we build in Bristol County.
Detached ADU
A standalone backyard cottage — the most private and flexible option, ideal for rental income or multigenerational living.
Attached ADU
A new addition connected to your existing home, such as an in-law suite with its own entrance, kitchen, and bath.
Conversion ADU
Converting existing space — a garage, basement, or attic — into a fully independent dwelling unit.
