Building a deck in Dennis
Dennis runs from bay to sound right next to Yarmouth, with five villages and the Bass River as its western border.
Dennis meets Cape Cod Bay on the north side, Nantucket Sound on the south side, and the Bass River along the Yarmouth line. Close to the bay, the sound, and Bass River, a deck takes more wind, sun, and salt than one inland, so we use corrosion-resistant hardware and low-maintenance boards where the location calls for it, and we check whether the lot is in a FEMA flood zone before we size the footings.
South-side streets in Dennis Port and West Dennis sit low and close to Nantucket Sound and Bass River, where flood zones are common, while the bay side along Route 6A is in the historic district.

“Mussato Building Group has been a loyal and trusted partner of ours for over ten years and one hundred projects. Their professionalism and quality of work are second to none. We look forward to working with them far into the future.”
Deck permits in Dennis
We prepare the drawings, file the applications, and schedule the inspections. Here is what a project like this usually needs:
- Building permit from the Dennis Building Department, with footing and framing details on the plans.
- Conservation Commission review if the deck is within 100 feet of a wetland, coastal bank, dune, or salt marsh.
- Flood-zone details on the plans if FEMA maps the lot in an AE or VE zone.
- A certificate from the Dennis Old King’s Highway committee if the deck is in the historic district along Route 6A and can be seen from a public way.
- New composite, PVC, and wood decks
- Deck replacement and tear-out
- Second-story and multi-level decks
- Stairs, landings, and entry steps
- Composite, PVC, cable, and wood railings
- Hot tub platforms framed for the load
- Footings, ledger flashing, and framing to code
- Permits and town approvals
Deck Builder in Dennis: FAQ
Do I need a permit for a deck in Dennis?
Yes, in most cases. A new or rebuilt deck needs a building permit from the Dennis Building Department, and in the Old King’s Highway district along Route 6A a deck visible from the street also needs an OKH certificate. If the lot is near a wetland, dune, or the shore, the Dennis Conservation Commission reviews it too. We handle the paperwork.
Do you build decks in Dennis Village and East Dennis?
Yes. We build and replace decks all over Dennis, including Dennis Village, East Dennis, South Dennis, West Dennis, and Dennis Port. Our base in South Yarmouth is about 3 miles away.
What decking holds up best in Dennis?
On a lot close to the bay, the sound, and Bass River, composite or PVC boards with stainless or hot-dip galvanized hardware are the low-maintenance choice. Farther from the water, cedar and pressure-treated wood also work well if you are willing to clean and stain them every few years.
Can you replace an old deck in Dennis instead of building a new one?
Yes. We remove the old deck, inspect the ledger, posts, and footings, and rebuild on a sound structure. Reusing the footings is possible when they are in good shape and meet current code.
