Design-Build Remodeling in Walpole, MA
Kitchens, bathrooms, basements, additions and ADUs for Walpole homes — designed and built by one accountable team, from our office next door in Foxborough.
Walpole is next door to our office.
Walpole runs from the village centre out to larger lots on the Foxborough line, and the two ends of town behave differently once you start adding bedrooms.
We work from 26 Patriot Place in Foxborough, and Walpole sits directly north of us. Being this close changes how a project actually runs — a site visit is a short drive rather than a scheduling exercise, and we already know how this particular building department works, which is never quite the same as the one in the next town.
ADUs in Walpole: what the bylaw actually says
Walpole allows one accessory dwelling unit by right in every residential district, capped at half the floor area of the principal dwelling or 900 square feet, whichever is smaller. Only one ADU is permitted per single-family house or lot. A detached ADU is subject to Limited Site Plan Review, and the Building Commissioner reviews the application within twenty-one days of filing. Short-term rentals in the unit are prohibited.
Walpole is specific about utilities in a way most towns are not: water and sewer must run directly to the main in the street, and the unit needs its own electrical service. That is a trenching and service-upgrade cost people rarely budget for, and it is worth pricing before you settle on where the unit goes.
Parking. Walpole has two stops, Walpole and Plimptonville, both on the Franklin line. One additional off-street space is required unless the property sits within half a mile of a transit station.
Current as of September 2026, from the Walpole Zoning Bylaw (as amended through 2025). Bylaws change — confirm the detail with the Walpole building department before you rely on it, or run your lot through our feasibility check and we will confirm it for you.
Sewer, septic, and what it means for your Walpole project
Walpole is split. Closer to the centre and the rail stops you are generally on sewer; further out, septic is common. On a sewered lot, adding bedrooms is largely a zoning and structural question. On an unsewered one it is a Title 5 question first, and that is a harder constraint than most homeowners expect.
Title 5 sizes a septic system at 110 gallons per day per bedroom, and it counts the bedrooms in the house and any new unit together. Adding a bedroom — whether in a finished basement, an addition or an ADU — can push the total past what your system was designed for, and the upgrade has to happen before the permit issues, not after. We check this at feasibility, because finding out late is what turns a budget into a problem.

Frequently asked questions
Can I build an ADU in Walpole?
Yes. Walpole allows one accessory dwelling unit by right in every residential district, capped at half the floor area of the principal dwelling or 900 square feet, whichever is smaller. One additional off-street space is required unless the property sits within half a mile of a transit station. We run the feasibility check before design so you know what your lot actually supports.
What is the permitting path in Walpole?
A detached unit goes through Limited Site Plan Review with a twenty-one day review window, and you will need water and sewer run to the street main plus a separate electrical service. We handle the filings and the coordination with the town as part of the project rather than leaving them to you.
Is Walpole on sewer or septic?
Walpole is mixed sewer and septic. It matters because Title 5 counts 110 gallons per day per bedroom across the house and any new unit together, so on an unsewered lot your existing system capacity can cap the number of bedrooms before zoning does.
Do you do kitchens and bathrooms in Walpole, or only additions?
All of it. Kitchens, bathrooms, basements, additions, ADUs and whole-home renovations, with design and construction under one contract so there is no gap between the drawings and the build.
How does a project start?
With a design consultation — a conversation about the house, what you want it to do, and what is realistic on your lot. No obligation, and no pressure to commit to a number before you understand the scope.
