What Is an Accessory Dwelling Unit?
An accessory dwelling unit (ADU) is a self-contained residential living space located on the same lot as a primary home. ADUs can take several forms, including:
- Internal ADUs – such as a basement conversion within an existing home
- Attached ADUs – a new construction addition connected to the primary residence
- Detached ADUs – a separate structure such as a backyard cottage or converted detached garage
In Massachusetts, an ADU must maintain a separate entrance, either directly from the outside or through a shared entry corridor that meets state building code requirements for safe egress. Additionally, the unit must be no larger than half the gross floor area of the principal dwelling or 900 square feet, whichever is smaller. Local municipal restrictions may also apply, including additional size limitations or restrictions on short-term rentals.
ADU Of Massachusetts guides their clients through all of these requirements, ensuring every build meets both state and local standards. Their team's deep familiarity with the permitting landscape in Massachusetts is a key advantage for homeowners looking to move their project forward efficiently.
