Massachusetts now allows accessory dwelling units (ADUs) by right in single-family zones statewide — making it easier than ever to add an in-law suite, a rental, or a private space for grown kids. BDaniel General Construction Corp builds ADUs across Massachusetts as basement and garage conversions, attached suites, and detached units — complete with their own kitchen, bath and entrance.
An ADU adds real value and flexible living space to your property, whether you want multigenerational living today or rental income down the road. We handle design, permits and the full build.
We build to the new statewide ADU law and your town’s requirements.
Full kitchen, bath and private entrance for true independence.
Flexible space for family now or rental income later.
