Finishing a basement 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.
Finishing the basement adds living space without adding to the footprint of the house. In Chatham, it is often simpler and faster to permit than an addition.
Near the sound, Pleasant Bay, and the ocean, groundwater can sit close to the surface, so every Chatham basement starts with a moisture check. If the house is in a FEMA flood zone, we also confirm how much of the space below the base flood elevation can be finished.
In Chatham, our work includes the restoration of a 1904 cottage overlooking Chatham Light, which received a 2022 Chatham Preservation Award, and a modern coastal estate with a Nano Wall glass system and two custom staircases.
In a Chatham summer home, a finished lower level often becomes the space for guests. Plan the work for fall and winter and it can be done before the season starts.

Basement Finishing in Chatham: FAQ
Do I need a permit to finish a basement in Chatham?
Yes. The Chatham Building Department issues the building permit, and licensed electricians and plumbers pull their own permits for their work. If the plan adds a bedroom, the Chatham Board of Health reviews septic capacity under Title 5.
Do you finish basements in Chatham Village and North Chatham?
Yes. We finish and remodel basements all over Chatham, including Chatham Village, North Chatham, South Chatham, West Chatham, and Chathamport. Our base in South Yarmouth is about 13 miles away.
Can a basement in Chatham have a bedroom?
It can if it has a code-compliant egress window or door, enough ceiling height, and septic or sewer capacity for the extra bedroom. Chatham is extending town sewer neighborhood by neighborhood, and homes not yet connected are on septic. On septic, the Chatham Board of Health has to approve the extra bedroom under Title 5 before we build it.
Is my basement too damp to finish?
Not necessarily. Close to the sound, Pleasant Bay, and the ocean, groundwater can be near the surface, so we look for water stains, white mineral deposits on the walls, and high humidity first. If there is a problem, it gets fixed before we frame.
