What are Accessory Dwelling Units (ADUs)?
An Accessory Dwelling Unit (ADU) is a secondary, independent housing unit located on the same lot as a primary single-family home. ADUs are also known by various other names, including granny flats, in-law suites, backyard cottages, or secondary units. They can be attached to the main house, such as a basement apartment or an addition, or detached, like a converted garage or a standalone cottage in the backyard.
ADUs are increasingly recognized as a flexible and affordable housing solution, contributing to diverse housing options within existing neighborhoods without significantly altering their character. They are self-contained living spaces with their own kitchen or kitchenette, bathroom, and sleeping area.
Types of ADUs:
- Detached ADU: A standalone structure separate from the primary residence, often built in a backyard. This can include new construction or converted garages.
- Attached ADU: An addition to the primary residence, sharing a wall or roof with the main house.
- Internal ADU: A living space created within the existing footprint of the primary home, such as a basement conversion or an attic apartment.
Benefits of Building an ADU
ADUs offer a multitude of benefits for homeowners, renters, and communities alike:
For Property Owners:
- Rental Income: Generate additional income to offset mortgage costs or provide financial flexibility.
- Flexible Living Space: Provide housing for family members (e.g., aging parents, adult children), caregivers, or even a home office or studio. ADUs can help older residents remain in their community and “age in place”.
- Increased Property Value: Enhance the overall value and appeal of your property.
- Downsizing Option: Allows older adults to downsize and remain in their community while renting out the main house.
For Renters:
- Affordable Housing: Offers smaller, more affordable rental units in desirable neighborhoods.
- Community Integration: Enables long-term residents to stay in their familiar communities.
For Communities:
- Increased Housing Supply: Addresses housing shortages by adding diverse and accessible housing options.
- Sustainable Development: Utilizes existing land and infrastructure more efficiently than new single-family home developments.
- Reduced Environmental Impact: Smaller units generally consume less water and electricity.
ADU Regulations in Massachusetts
Massachusetts has made significant strides in promoting ADU development. The Affordable Homes Act, signed into law by Governor Healey on August 6, 2024, allows ADUs up to 900 square feet to be built by-right in single-family zoning districts statewide. This historic legislation aims to counter rising housing costs and increase housing options across the Commonwealth.
Key aspects of the Massachusetts ADU law include:
- ADUs must have a separate entrance, either directly from the outside or through a shared entry hall.
- ADUs can be no larger than half the gross floor area of the principal dwelling or 900 square feet, whichever is smaller.
- Municipalities can impose reasonable restrictions on site plan review, Title V requirements, dimensional setbacks, and short-term rentals.
- Municipalities cannot require owner occupancy or family relationship for the ADU or principal dwelling, nor can they require a special permit or other discretionary zoning approval for ADU use or rental.
- Parking requirements are also limited, with no parking required for ADUs within 0.5 miles of a commuter rail, subway, ferry, or bus station.
