Building an ADU in Boston?
Boston has actively expanded ADU opportunities citywide; in three-decker neighborhoods like Dorchester and JP, interior and basement ADUs are often the cleanest path.
Under Massachusetts' 2025 by-right ADU law, a conforming accessory dwelling unit of up to 900 sq ft no longer needs a special permit in single-family zones — but Boston's local dimensional rules still decide what fits. We give you a clear, lot-specific answer.
Local zoning, handled
Boston's neighborhood-specific zoning and ZBA process reward a well-prepared application and early abutter outreach.

Boston ADU & Zoning FAQ
Can I build an ADU in Boston, MA?
In most cases, yes. Massachusetts now allows accessory dwelling units of up to 900 square feet by-right in single-family zoning districts statewide. Boston has actively expanded ADU opportunities citywide; in three-decker neighborhoods like Dorchester and JP, interior and basement ADUs are often the cleanest path. Local dimensional rules still apply, so we confirm exactly what your Boston parcel allows before you design.
What kind of ADU works best in Boston?
Boston has actively expanded ADU opportunities citywide; in three-decker neighborhoods like Dorchester and JP, interior and basement ADUs are often the cleanest path. The right type depends on your lot, your goals, and the Boston bylaw — we test-fit the options before you commit to plans.
What zoning approvals do I need for a project in Boston?
It depends on the parcel and what you're proposing. Boston's neighborhood-specific zoning and ZBA process reward a well-prepared application and early abutter outreach. We start with a zoning read so you know whether your project is by-right or needs a special permit, variance, or site plan review in Boston.
Does transit affect my Boston project's parking requirements?
It can. Boston is served by Red, Orange & Blue Lines, plus commuter rail, and Massachusetts limits the parking a community can require for a by-right ADU — with that requirement waived near transit. We confirm how it applies to your specific address.
Which Boston neighborhoods does Pavli work in?
We work throughout Boston, including Dorchester, Jamaica Plain, East Boston, and Roslindale. Wherever your parcel sits, we pull the local zoning and assessor data and give you a clear read.
