Adding on to a home in Chatham
Chatham sits at the elbow of the Cape, surrounded by water on three sides, with shingled capes and summer cottages from its fishing-village past.
Chatham has many shingled capes and summer cottages that families want to grow without losing their character. In our restoration of a 1904 cottage overlooking Chatham Light, which received a 2022 Chatham Preservation Award, the house was lifted, relocated, and rebuilt while its original features were kept wherever possible.
If an addition means taking down part of a house more than 75 years old, the Historical Commission reviews it first. Much of the shoreline is in FEMA flood zones, where a large addition can bring the whole house under the flood standards, and an added bedroom depends on whether your street is on town sewer yet or still on septic.

Addition permits in Chatham
We prepare the drawings, file the applications, and schedule the inspections. Here is what a project like this usually needs:
- Building permit from the Chatham 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.
- 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

Home Additions in Chatham: FAQ
Do I need a permit for a home addition in Chatham?
Yes. The Chatham Building Department issues the building permit after a zoning review of setbacks, lot coverage, and height. We prepare the drawings and file the applications.
Do you build additions in Chatham Village and North Chatham?
Yes. We build additions all over Chatham, including Chatham Village, North Chatham, South Chatham, West Chatham, and Chathamport. Our base in South Yarmouth is about 13 miles away.
Will an addition trigger flood rules on my Chatham house?
It can. In a FEMA flood zone, an addition large enough to count as a substantial improvement means the whole house has to meet the flood standards. We check the flood map and the scope before design.
Can you match my existing siding, roof, and trim?
Yes. Matching the roof pitch, the siding and trim, and the windows of the existing house is how we build every addition.
