Adding on to a home in Cotuit
Cotuit sits on a peninsula in the southwest corner of Barnstable, between Cotuit Bay and Popponesset Bay, with the Santuit River on the Mashpee line. Its Main Street village center is listed on the National Register of Historic Places.
Many Cotuit houses date from the 1800s and early 1900s, and the village center is a National Register historic district. An addition to one of these homes works best when the roof pitch, the trim, and the windows match what is already there, which is how we build every addition.
The Town of Barnstable issues the permits. If part of a house more than 75 years old has to be taken down to make room, the Historical Commission may review it. On Cotuit Bay and Popponesset Bay, the Conservation Commission’s 100-foot buffer and the flood map decide where an addition can go.

“I’ve worked with Joe and his team on several projects and the workmanship is consistently excellent. Their attention to detail and the ease of communication is second to none. Highly recommended.”
Addition permits in Cotuit
We prepare the drawings, file the applications, and schedule the inspections. Here is what a project like this usually needs:
- Building permit from the Barnstable Building Department, with drawings that show how the addition ties into the existing structure.
- Zoning review of setbacks, lot coverage, and height, and a Zoning Board of Appeals hearing if the existing house does not meet today’s rules and the addition needs relief.
- Board of Health sign-off on the septic system when the addition adds a bedroom.
- Conservation Commission filing for work within 100 feet of a wetland, a pond, or a coastal bank.
- Barnstable Historical Commission review if a building more than 75 years old is being demolished.
- Room additions & second-floor additions
- Garage additions & conversions
- Sunrooms & enclosed porches
- In-law suites & bump-outs
- Living space & kitchen expansions
- Structural integration with existing home
- Permit coordination & code compliance
- Matching materials & finishes
