Buying Land in Dukes County, Massachusetts (Martha's Vineyard)
County seat Edgartown. This page covers Martha's Vineyard and the Elizabeth Islands' inland, non-beachfront land-buying framework -- shore-town real estate is covered by our sister site, usbeachlife.com. The genuinely distinctive fact here is the Martha's Vineyard Commission, a regional body with real regulatory authority across all seven Dukes County towns, layered on top of each town's own zoning.
Zoning is set by each of the seven towns, not the county
As everywhere in Massachusetts, zoning authority under MGL Chapter 40A belongs to the individual city or town, and Dukes County is no exception. Its seven towns -- Edgartown, Oak Bluffs, Tisbury, West Tisbury, Chilmark, and Aquinnah on Martha's Vineyard itself, plus Gosnold, which covers the separate Elizabeth Islands chain (mainly populated on the outermost island, Cuttyhunk) -- each run their own zoning bylaw, building department, and zoning board of appeals. A parcel's buildable use, minimum lot size, and setback requirements depend on which of those seven towns it's in; there is no countywide zoning map or ordinance layered underneath.
This project's sister site, usbeachlife.com, covers Martha's Vineyard's beach-market real estate. This hub instead focuses on the zoning and regional-review framework that applies islandwide, regardless of a parcel's distance from the water -- because the most distinctive regulatory feature of Dukes County, the Martha's Vineyard Commission, applies to development decisions across the whole island, not just its shoreline.
The Martha's Vineyard Commission: a regional review layer since 1974
On July 27, 1974, Governor Francis Sargent signed legislation (Chapter 637 of the Acts of 1974) transforming the former Dukes County Planning and Economic Development Commission into the Martha's Vineyard Commission (MVC) -- a regional land-use body with real regulatory power, not just an advisory planning agency. The MVC held its first meeting that December and has reviewed hundreds of the island's most significant development projects since, as "Developments of Regional Impact" (DRIs), a project category triggered by a project's scale or by a town board's own request for Commission review. Along with the Cape Cod Commission, the MVC is one of only two regional bodies in Massachusetts with this kind of DRI and District of Critical Planning Concern (DCPC) regulatory authority -- nowhere else in the state does a body above the town level have comparable power over land use decisions.
The Commission is structured to represent the whole island: 21 members, including one selectman or designee from each of the six Vineyard towns, nine members elected at-large islandwide, four non-resident members appointed by the Governor (with voice but not vote), one county commissioner, and one member of the Governor's cabinet or designee. That structure -- weighted toward island-wide, at-large representation rather than one vote per town -- is part of what gives the MVC the ability to impose conditions, or block approval, on a project that complies with the underlying town zoning bylaw but that the Commission finds has regional impacts beyond what the town alone should decide. See our dedicated zoning standalone for Dukes County for more on the DRI review process and its current thresholds.
County government's uncertain future, and what remains today
Dukes is one of only six Massachusetts counties -- with Barnstable, Bristol, Nantucket, Norfolk, and Plymouth -- that was never abolished under the 1997-2000 wave of county eliminations (MGL Ch. 34B). A seven-member Board of County Commissioners, elected countywide with no more than two commissioners from the same town, still meets roughly twice a month at the county's Administration Building in Edgartown, and county functions include a Registry of Deeds, Health and Human Services coordination, and a Sheriff's Office. Unusually for this project's coverage, that structure is currently in flux: as of a February 2026 report, the Dukes County Commissioners were themselves actively studying whether to restructure or abolish county government entirely, as part of an overdue charter review -- a live, disclosed uncertainty rather than a settled fact.
None of that changes the zoning picture either way: as everywhere in Massachusetts, county government here has never held zoning authority, and the Martha's Vineyard Commission's regulatory power comes from its own 1974 enabling legislation, not from county government -- so a restructuring or abolition of the county commission would not, on its own, change how the MVC operates. For a Dukes County land purchase, confirm zoning district, permitted use, and dimensional requirements with the specific town's building or zoning office first; separately check whether the project could trigger MVC DRI review, particularly for any subdivision or larger commercial proposal; and, for a parcel needing a new septic system, confirm Title 5 perc-test and Board of Health procedure with the specific town, same as anywhere else in Massachusetts. A parcel touching a wetland, coastal bank, or great pond still triggers a separate Conservation Commission review under the statewide Wetlands Protection Act.
Who to Call Before Buying Land in Dukes County
No direct WebFetch to dukescounty.gov, mvcommission.org, or town sites was performed this pass (no WebFetch tool was available in this session); department details reflect WebSearch-indexed content -- confirm current structure, hours, and fees directly. Zoning is a per-town function; there is no single "Dukes County zoning office" to call for a specific parcel. Dukes County government's own structure was reported as under active internal review as of February 2026 -- confirm current status directly.
