West Tisbury Vacation Rental Investment: A Bylaw Already on the Books

West Tisbury's Own STR Bylaw: Finalized in January 2025

Here's the fact that should anchor any West Tisbury rental-investment decision: this town's own short-term rental bylaw is not a proposal working its way toward a future vote -- it is done. The Vineyard Gazette's January 3, 2025 report, "West Tisbury Finalizes Short-Term Rental Rules," confirms the town completed and adopted its own STR bylaw at that date. That is a real, specific, dated local outcome, and it is West Tisbury's alone -- a related, similarly-worded Gazette headline about a town's short-term rental cap vote belongs to the separate town of Tisbury (its own, independently confirmed story), and the two should never be conflated even though the town names look nearly identical.

What this page will not do is guess at the bylaw's mechanics. A later Vineyard Gazette piece, "Short-Term Rental Regulations Head to Town Meeting" (March 26, 2026), surfaced in the same research pass and could plausibly describe some further West Tisbury STR refinement -- or it could, per its nearly identical headline pattern, actually belong to Tisbury's own separate cap-elimination story instead. This research could not disentangle which town that March 2026 piece is actually about, so it is not used here as a West Tisbury-specific fact. Similarly, the January 2025 bylaw's own numeric provisions -- any registration process, unit cap, or owner-occupancy requirement -- were not extracted this pass. The town's own hosted "WT Short-Term Rental By-Law" document, available through westtisbury-ma.gov, is the direct, primary source to read before assuming any specific rule applies to a property you're considering.

Massachusetts Short-Term Rental Law: The Statewide Baseline Underneath Any Local Rule

Whatever West Tisbury's own bylaw specifies in detail, Massachusetts' statewide short-term rental law sits underneath it exactly the same as in every other Massachusetts town. Chapter 337 of the Acts of 2018 requires short-term rental operators to register with the state Department of Revenue, creates a public registry of registered units, and mandates a minimum of $1,000,000 in liability insurance coverage -- whether through the operator's own policy or coverage provided by the booking platform. Layered on top of registration and insurance is a room-occupancy excise: a 5.7% state excise, with cities and towns given the option to add a local-option excise of up to 6% on top of that -- a combined baseline as high as 11.7% before any regional add-on. Whether West Tisbury has adopted the full 6% local-option excise, a lower rate, or none at all was not confirmed in this research pass -- that is a direct question for the West Tisbury Assessor's Office or Town Clerk, not something to assume from the statewide ceiling.

The Water Protection Fund Question: An Open Issue for Dukes County, Not a Settled Number

This site's own Barnstable County (Cape Cod) research found that a further 2.75% "Cape Cod and Islands Water Protection Fund" excise applies on top of the state-plus-local stack in Barnstable County towns, bringing that county's combined total as high as 14.45%. Whether that same fund's "Islands" language extends to Dukes County -- and therefore to West Tisbury -- was not independently confirmed in this research pass, consistent with the identical open question already flagged on this site's Edgartown and Tisbury pages. The fund's name explicitly references "Islands," which would seem to point toward Martha's Vineyard being included, but no Massachusetts Department of Revenue or Cape Cod Commission document listing exactly which counties and towns are subject to the excise was located or confirmed for West Tisbury specifically.

That leaves a genuinely open question rather than a number to publish as fact: is West Tisbury's combined short-term rental tax stack 5.7% state plus up to 6% local (an 11.7% ceiling), or does a further 2.75% push it toward something closer to 14.45%, as in Barnstable County? Don't assume either answer. Confirm the current combined rate directly with the Massachusetts Department of Revenue's Room Occupancy Excise Tax page, the West Tisbury Assessor's Office, or a Massachusetts CPA before building a specific number into a rental pro forma.

What Actually Sets West Tisbury's Rental Stock Apart: Farmland, Not a Harbor

West Tisbury's rental product is genuinely different in kind from the harbor-village rentals this site has covered in Edgartown, Oak Bluffs, and Tisbury. It is the island's largest town by land area and its most inland-feeling one -- a historic village core built around the Grange Hall (1859), Alley's General Store, and the Mill Pond, sitting well back from any harbor, surrounded by the working farms and farm stands documented by the Martha's Vineyard Agricultural Society (whose own Fair traces back to roughly 1861) and by conservation land held by the Martha's Vineyard Land Bank, the Vineyard Conservation Society, and the Sheriff's Meadow Foundation. For a short-term rental buyer, that translates into a genuinely distinct product: larger, more private lots on or near farmland and conservation land, a quieter setting than a walk-to-the-ferry or walk-to-the-harbor rental, and renters drawn to a rural New England-village atmosphere rather than a boat-basin or a downtown strip. West Tisbury's water frontage runs through Tisbury Great Pond (a coastal salt pond periodically breached to the ocean through its barrier beach) and Trustees of Reservations-managed south-shore conservation land at Long Point, plus a north-shore stretch at Lambert's Cove -- real ocean and pond access, but concentrated and land-trust-adjacent rather than built up around a marina.

A related, genuinely distinctive logistics fact: Martha's Vineyard Airport (MVY) sits in West Tisbury, not in any of the harbor towns -- a real, practical convenience for renters flying in, and a point of difference this site's Edgartown, Oak Bluffs, and Tisbury pages could not claim for their own towns. No West Tisbury-specific short-term rental occupancy rate, nightly rate, or seasonal-demand figure was confirmed in this research pass; treat the rural/agricultural/quieter-setting framing as a real market-character difference, not a guarantee of rental performance, and get a property-specific income projection from a local property manager.

A Housing-Policy Backdrop Worth Knowing Before You Underwrite

West Tisbury's Select Board and town meeting have been actively using more than one policy lever to manage affordability and homeownership pressure at the same time its STR bylaw was finalized. The town increased its residential tax exemption in November 2025, per Martha's Vineyard Times coverage ("West Tisbury Boosts Tax Exemption to Preserve Homeownership," Nov. 20, 2025) explicitly framed around preserving year-round homeownership -- a mechanism that, by design, shifts tax burden away from owner-occupied homes and toward second homes and investment property, which is directly relevant to the economics of a non-owner-occupied short-term rental purchase here. Separately, the town awarded an affordable/senior-housing project contract in January 2025 and broke ground on affordable duplexes by March 2026, per Vineyard Gazette coverage -- a comparatively fast-moving local housing-supply story. The exact size of the November 2025 exemption increase, its effective date, and the new housing units' exact count were not confirmed in this research pass -- confirm both directly with the West Tisbury Assessor's Office and the town's Housing Committee before assuming either figure in a purchase model.

What This Means for a Buyer: A Framework, Not a Promise

Here's what's sourced and what isn't. Sourced: a real, dated, finalized West Tisbury-specific short-term rental bylaw, adopted as of January 3, 2025, distinct from the separate town of Tisbury's own cap-retention vote; Massachusetts' statewide Chapter 337 framework -- DOR registration, the public STR registry, the $1,000,000 minimum liability insurance requirement, the 5.7% state room-occupancy excise, and up to 6% local option, all confirmed and consistent with every other Massachusetts market this site has covered; West Tisbury's genuinely distinct rural/agricultural/larger-lot market character and its status as home to the island's only airport; and a November 2025 residential tax exemption increase plus an active affordable-housing construction pipeline, both real, dated, current governance facts.

Not sourced, and not something this page will guess at: the finalized bylaw's specific numeric provisions (registration mechanics, any unit cap, owner-occupancy rules); whether the March 26, 2026 "Short-Term Rental Regulations Head to Town Meeting" Gazette headline describes West Tisbury or, as its identical headline pattern elsewhere suggests, the separate town of Tisbury; whether West Tisbury has adopted the full 6% local-option room excise; whether West Tisbury's combined short-term rental tax stack includes the 2.75% Cape Cod and Islands Water Protection Fund excise; any current (2025-2026) median or average home sale price for West Tisbury; and the current West Tisbury property tax mill rate. This page is independent research, not a substitute for direct confirmation, and none of it is legal, tax, or investment advice. Before underwriting a West Tisbury short-term rental purchase, confirm the finalized bylaw's exact terms with the West Tisbury Town Clerk's office or westtisbury-ma.gov, confirm the combined tax rate with the Massachusetts Department of Revenue or a Massachusetts CPA, and get a property-specific rental income projection from a local property manager -- and consult a licensed Massachusetts tax professional and real estate attorney before relying on any figure in this page for a purchase decision.
