Adding on to a home in New Seabury
New Seabury is a resort community on Nantucket Sound in Mashpee, made up of separate villages such as Maushop Village, The Mews, Bright Coves, Fells Pond, and Triton Sound.
In New Seabury, an addition needs the community’s approval as well as the town’s. The architectural review committee looks at the design, with close attention to height, and the Town of Mashpee issues the building permit. We prepare both submissions.
In villages like Maushop Village, homes sit close together, so we plan access, staging, and work hours with the neighbors in mind. Near the sound and Popponesset Bay, the flood map matters: an addition large enough to count as a substantial improvement brings the whole house under the flood standards.

“As the General Manager of Pretty Picky Properties I’ve had the pleasure of working with Joe and his team for nearly 10 years. Joe’s carpentry skills are unmatched. He’s always respectful, finishes on time, priced well, and transparent from start to finish. You will not regret hiring Mussato Building Group.”
Addition permits in New Seabury
We prepare the drawings, file the applications, and schedule the inspections. Here is what a project like this usually needs:
- Building permit from the Mashpee 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.
- Approval from New Seabury’s architectural review committee and homeowners’ association, in addition to the town permit.
- Room additions & second-floor additions
- Garage additions & conversions
- Sunrooms & enclosed porches
- In-law suites & bump-outs
