Egress windows in Barnstable
Barnstable is the largest town on Cape Cod, with seven villages that run from the Route 6A homes of Barnstable Village to the harbors of Hyannis, Osterville, and Cotuit.
An egress window is usually what makes a basement bedroom legal. Parts of Hyannis are on town sewer and the town is extending sewer to other villages, but most homes in Barnstable still use septic systems. On septic, the new bedroom also needs the Barnstable Board of Health to confirm the system can carry it under Title 5, so we check that before we cut the foundation.
Near the bay and the sound, groundwater and heavy rain are the main risks for a new window well. We build the drainage at the bottom of the well and grade the soil around it so water moves away from the opening.
In the Old King’s Highway district of Barnstable along Route 6A, an egress window on a side of the house that can be seen from the street can need a certificate from the Barnstable Old King’s Highway committee. We place the window where it works for the room and for the review.

“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.”

Basement Egress Windows in Barnstable: FAQ
Do I need a permit for an egress window in Barnstable?
Yes. Cutting a foundation wall is structural work, so the Barnstable Building Department issues a building permit and inspects the opening. We handle it.
Do you install egress windows in Hyannis and Barnstable Village?
Yes. We install basement egress windows all over Barnstable, including Hyannis, Barnstable Village, West Barnstable, Centerville, Osterville, Marstons Mills, and Cotuit. Our base in South Yarmouth is about 6 miles away.
What size does the egress window need to be?
At least 5.7 square feet of clear opening, at least 24 inches of clear height and 20 inches of clear width, with the sill no more than 44 inches above the floor.
Does a basement bedroom in Barnstable need anything else?
Enough ceiling height, and septic or sewer capacity for the extra bedroom. Parts of Hyannis are on town sewer and the town is extending sewer to other villages, but most homes in Barnstable still use septic systems.
