Fencing in Nantucket, Massachusetts

Fencing is not an energy-efficiency measure, so no Mass Save or energy rebate applies to a fence, and there is nothing to chase either way. The local rules are unusually strict on Nantucket. The zoning bylaw typically limits fences to about 6 ft in rear and side yards and lower within the front-yard setback, so confirm with the building authority. Critically, nearly the whole island is a historic district, so the Historic District Commission (HDC) must approve fence design, height, and materials before you build, and it favors traditional cedar and post-and-rail over vinyl or chain-link. Because the island is ringed by beaches, harbors, and ponds, the Conservation Commission reviews fences within roughly 100 ft of a wetland or coastal bank under the Wetlands Protection Act. Pool fences must meet MA building code: at least 4 ft tall with self-closing, self-latching gates.

Nantucket generally requires a building or zoning permit for a new fence, and the contractor must hold state Home Improvement Contractor (HIC) registration. Most projects need Historic District Commission (HDC) approval first, since the HDC governs the look of nearly every property on the island. Set post footings about 48 inches below grade for frost, and in sandy island soil installers widen footings and add concrete against wind. Pull a plot plan before building on a boundary, and call Dig Safe before digging. Coastal and pond-side lots add a Conservation Commission step.

Nantucket fence pricing is the highest in Massachusetts, driven by ferry freight, limited island labor, and HDC-mandated traditional materials. Expect roughly $45–$80 per linear foot for cedar privacy or post-and-rail, $55–$95 for salt-tolerant aluminum, and more for custom historic-style work, all installed. A 150 ft cedar run can run $9,000–$16,000 or higher. Material shipping, HDC design requirements, sandy-soil footing upgrades, and Conservation filings all push the figure up.

Nantucket has about 14,065 year-round residents but 12,287 housing units in Nantucket County, the island's huge seasonal market filling most of those homes only part of the year. The median home age is near 42 years, though the historic core dates to the whaling era. As an island, every property faces salt air, wind, and sandy soil, and nearly the entire island sits within a designated historic district. Cedar and salt-tolerant aluminum fences, plus the traditional weathered-cedar and post-and-rail styles, dominate. Strict design review and the cost of shipping materials by ferry shape every Nantucket fence project.
