Decks & Porches in Aquinnah — what to know

Rebates & incentives

Decks do not qualify for Mass Save rebates. Aquinnah is in Eversource territory, but that is irrelevant to deck permitting. What matters here is the permitting gauntlet. The Gay Head Cliffs and surrounding bluffs are subject to coastal bank and land subject to coastal storm flowage review under the Wetlands Protection Act, administered through the Aquinnah Conservation Commission. Any deck within 100 feet of the coastal bank, a pond, or a stream requires a Notice of Intent and Order of Conditions before a building permit can issue. The town also has its own Historic District Commission, and any exterior change visible from a public way, including a new deck or porch on a period home near the village, may require Historic District Commission approval. Factor at least eight to twelve weeks for conservation and historic review into project timelines.

Permits in Aquinnah

Aquinnah's building department issues permits under 780 CMR, but coastal location means Conservation Commission review under the Wetlands Protection Act is almost always required first. Frost depth on the Vineyard is typically 36 to 42 inches, somewhat shallower than mainland MA, but local practice often specifies 48 inches for margin. Guardrail height (36 inches), baluster spacing (under 4 inches), and ledger attachment are all inspected. Historic District Commission review may be needed for visible exterior changes.

Where a permit is required, decks & porches work in Aquinnah is filed with the Aquinnah Building Department; see the Aquinnah Building Department’s contact, portal and who pulls the permit on permits.llc.

Typical project cost

Deck and porch work on Martha's Vineyard runs substantially higher than mainland MA because of the ferry logistics for materials and crews. Pressure-treated pine decks run $24–$38 per square foot and composite decks run $40–$65 per square foot. A 300-square-foot deck in Aquinnah typically costs $10,000–$20,000 installed, depending on material and site access. Coastal-grade stainless steel hardware, required near salt air, adds $500–$1,200 over standard galvanized fasteners on any project within a few hundred feet of the water.

About Aquinnah homes

Aquinnah sits at the western tip of Martha's Vineyard in Dukes County, with 708 residents and 563 housing units. The median home is 46 years old. Aquinnah is home to the Wampanoag Tribe of Gay Head and includes the Gay Head Cliffs, a National Natural Landmark. The town has a very high proportion of seasonal and vacation properties relative to year-round residents, and the coastal bluff setting means nearly every deck project intersects with coastal erosion, Conservation Commission review, or historic district considerations.

Common questions — Decks & Porches in Aquinnah

Do I need Conservation Commission approval for a deck in Aquinnah?
Almost certainly yes. Aquinnah's coastal location means most properties are within 100 feet of a coastal bank, pond, or wetland. File a Notice of Intent with the Aquinnah Conservation Commission under the Wetlands Protection Act and get an Order of Conditions before the building department will issue a permit.
Does Aquinnah's Historic District affect deck permits?
If your property is in or near the Gay Head Historic District and the deck is visible from a public way, you may need Historic District Commission approval before the building permit issues. Confirm with the Aquinnah building department at the start of the project.
Why is deck construction so much more expensive on Martha's Vineyard?
Ferry logistics for materials and crews add significantly to costs on the Vineyard. Composite decking pallets, lumber, and equipment all have to cross on the ferry, and most contractors either base their crews on-island or factor in the ferry time. Budget 30 to 50 percent more than a comparable mainland project.
Do I need stainless steel hardware for a deck near the bluffs?
Yes. Salt air corrodes standard galvanized hardware over time. Coastal projects in Aquinnah should use stainless steel fasteners and hardware for all structural connections. This is good practice and some inspectors will flag standard galvanized on projects within obvious salt air distance of the water.
How long does the permitting process take in Aquinnah?
Conservation Commission review alone takes four to eight weeks from Notice of Intent filing to Order of Conditions. Add the building department permit and any Historic District Commission review and the full permitting timeline runs eight to fourteen weeks. Plan well ahead of the construction season.
