Building an ADU in Cambridge?
Cambridge's mix of historic homes and newer multifamily means ADUs range from carriage-house and basement conversions to detached units — each with its own review 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 Cambridge's local dimensional rules still decide what fits. We give you a clear, lot-specific answer.
Local zoning, handled
Cambridge layers overlay districts and historic review on top of base zoning — a clear read keeps surprises out of the schedule.
If your parcel sits in a historic or conservation district, we factor that review in from day one — it drives both design and timeline.

Cambridge ADU & Zoning FAQ
Can I build an ADU in Cambridge, 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. Cambridge's mix of historic homes and newer multifamily means ADUs range from carriage-house and basement conversions to detached units — each with its own review path. Local dimensional rules still apply, so we confirm exactly what your Cambridge parcel allows before you design.
What kind of ADU works best in Cambridge?
Cambridge's mix of historic homes and newer multifamily means ADUs range from carriage-house and basement conversions to detached units — each with its own review path. The right type depends on your lot, your goals, and the Cambridge bylaw — we test-fit the options before you commit to plans.
What zoning approvals do I need for a project in Cambridge?
It depends on the parcel and what you're proposing. Cambridge layers overlay districts and historic review on top of base zoning — a clear read keeps surprises out of the schedule. 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 Cambridge.
Does transit affect my Cambridge project's parking requirements?
It can. Cambridge is served by Red Line — Harvard, Porter, Central, Kendall, 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 Cambridge neighborhoods does Pavli work in?
We work throughout Cambridge, including Porter Square, Central Square, North Cambridge, and Cambridgeport. Wherever your parcel sits, we pull the local zoning and assessor data and give you a clear read.
