Welcome to Mass ADU Realty
Passion for Compact, Functional, and Stylish Living
An accessory dwelling unit is a small residential living space located on the same lot as another home. ADUs can play a significant role in our housing crisis. The ADU policy recently signed by the governor allows property owners to build an ADU without having to get special or discretionary approval from the local zoning board.
ADUs can be internal within an existing primary residence, like converting a basement into an apartment, attached to a primary residence as a new construction addition, or completely detached, like a cottage or converted detached garage in a backyard.
The Affordable Homes Act amends the definition of accessory dwelling unit under Section 1A of Chapter 40A of the General Laws to clarify that the maximum size of an ADU is no more than half of the gross floor area of the principal dwelling, or 900 square feet, whichever is smaller. The definition was also amended to prohibit owner-occupancy requirements and unreasonably restricting the creation or rental of an ADU.
On Aug. 6, 2024, Governor Healey signed the Affordable Homes Act into law (Chapter 150 of the Acts of 2024). Section 8 of the Affordable Homes Act amends the Zoning Act to allow ADUs up to 900 square feet to be built by right in single-family zoning districts. The historic legislation authorized $5.16 billion in spending over five years along with nearly 50 policy initiatives to counter rising housing costs. The new law on ADUs is an example of a small policy change that will make a big difference. Massachusetts is a leader in finding innovative solutions to our biggest challenges. Rising housing costs and homelessness are not unique challenges for our state, but we can lead the way in solving them.
An ADU must:
- Maintain a separate entrance, either directly from the outside or through an entry hall or corridor shared with the principal dwelling sufficient to meet the requirements of the state building code for safe egress;
- Be either no larger than half the gross floor area of the principal dwelling or 900 square feet, whichever is smaller;
- Meet local municipal restrictions, including, but not limited to, additional size restrictions and/or restrictions or prohibitions on short-term rental if the city or town decides to impose.
