Frequently Asked Questions

  • An ADU (Accessory Dwelling Unit) is a self-contained living space located on the same property as your main home. Think of it as a complete, independent home—just smaller. To qualify as a "Protected Use ADU" under Massachusetts law, it must have:

    • Its own kitchen (cooking facilities)
    • Its own bathroom (sanitation facilities)
    • Its own bedroom (sleeping area)
    • A separate entrance (independent access)

    It's essentially a fully functional home on your property—whether it's a converted basement, an addition to your house, or a detached cottage in your backyard.

  • In most cases, NO. This is the game-changer.

    Under the Affordable Homes Act (signed August 2024, effective February 2025), ADUs are now allowed "by-right" in all single-family zoning districts across Massachusetts. This means:

    No special permit required for standard ADU projects
    No discretionary hearings before Zoning Boards
    No neighbor approval needed
    Municipalities cannot unreasonably prohibit ADUs

    You still need:

    • Building permit (standard process)
    • Compliance with building codes
    • Health department approval (septic, if applicable)

    Bottom line: The state has removed the biggest barrier—arbitrary zoning restrictions.

  • Massachusetts law sets a clear maximum:

    Your ADU cannot exceed the SMALLER of:
    1. 900 square feet, OR
    2. 50% of your main house's gross floor area (GFA)

    Example:

    • Main house: 2,400 sq ft → Max ADU: 900 sq ft (because 50% = 1,200, but 900 is the cap)
    • Main house: 1,600 sq ft → Max ADU: 800 sq ft (because 50% = 800, which is under the 900 cap)

    What counts as GFA?

    • Finished basements (if ceiling height ≥7 feet)
    • Main floors
    • Finished attics/lofts

    What doesn't count?
    • Crawl spaces
    • Unfinished attics
    • Open porches
    • Garages (unless converted into living space)

  • No. This is a major change under the new law.

    Previous Rule (Pre-2025): Many towns required owner-occupancy.

    New Rule (2025+): Towns are prohibited from requiring owner-occupancy of either the main house or the ADU.

    What this means:
    • You can live in the main house and rent the ADU
    • You can live in the ADU and rent the main house
    • You can rent BOTH if you move but keep the property
    • Maximum investment flexibility

    This makes ADUs attractive for:
    • Investors
    • People who may relocate for work
    • Families planning future moves

  • Be careful here. The answer is: It depends on your town.

    State Law: Allows municipalities to regulate short-term rentals.

    Most Towns: Ban short-term rentals (typically defined as less than 30-31 days) for ADUs.

    Examples:
    • Lowell: Requires minimum 30-day rentals
    • Natick: Similar short-term rental restrictions
    • Boston area towns: Most prohibit short-term ADU rentals

    Long-term rentals (30+ days) are protected and allowed statewide.

    Why the restriction?
    The state wants ADUs to provide stable, long-term housing—not hotel-style accommodations.

    Our Advice: If you're planning to rent, plan for long-term tenants (6-12 month leases). This also provides more stable income.

  • Good news: Under the new law, neighbors cannot block your ADU.

    Legal Reality:
    • ADUs are "by-right" in MA (no special permit needed)
    • No public hearing where neighbors can object
    • Municipalities cannot require neighbor approval
