Short-term rental (Airbnb) rules in Hamilton, Massachusetts
Unclear for a main home, and not allowed in an ADU. Hamilton has no short-term rental registration or license in the bylaws we reviewed, and its zoning bylaw doesn't list short-term rentals as a use, though it treats any unlisted use as prohibited. The zoning bylaw expressly bans short-term rentals in accessory dwelling units, so confirm with the Building Commissioner before listing your home.
| Short-term rental in an ADU | Prohibited [1] |
| Local STR registration or license | None found in the bylaws reviewed [2] |
| Unlisted uses | Construed to be prohibited [2] |
| Boarders in a single-family home | Up to 3, by right in R-1A, R-1B and RA [3] |
No local short-term rental program
Neither Hamilton's zoning bylaw nor its general bylaws (as compiled in May 2024) set up a short-term rental registration, license, fee, cap or minimum stay. State registration and taxes under G.L. c. 64G still apply (see the state section).
Accessory dwelling units
The one direct rule is in the ADU section: short-term rentals as defined in G.L. c. 64G, §1 are prohibited in accessory dwelling units [1]. If you have an ADU, it can be rented only for longer stays.
Renting the main house
The zoning bylaw allows only the uses listed in its Table of Use Regulations, and "any use not listed shall be construed to be prohibited" [2]. Short-term rentals are not listed in the table, and the bylaw doesn't say whether renting out a single-family home for short stays counts as ordinary residential use. Inns and bed and breakfasts appear only in overlay districts (the Estate Overlay District, and the Brown's Hill Overlay District at the Planning Board's discretion), not as ordinary residential uses. Because of this gap, ask the Building Commissioner how the town treats short-term rental of a single-family home before you list it.
Boarders
The use table allows up to three boarders in a single-family dwelling by right in the R-1A, R-1B and RA districts [3]. The bylaw defines a boarder as a non-family member furnished sleeping accommodations and meals "for consideration", excluding bed and breakfast guests [4]. This covers lodgers living in the home, not short-stay guests.
About these sources
The general bylaw compilation we reviewed runs through November 2023, so a short-term rental bylaw adopted at a later town meeting would not appear in it.

Massachusetts' short-term rental law
Since July 1, 2019, M.G.L. c. 64G has taxed and regulated short-term rentals: stays of 31 days or less in a home, apartment, condo or room booked in advance.
State requirements:
- Register with the Department of Revenue (DOR) on MassTaxConnect and get a Certificate of Registration for each property. Post it in the unit.
- 14-day exemption: if you rent a property 14 days or fewer in a calendar year, no tax is due. You still have to register and file DOR's declaration by January 15 each year. Go over 14 days and you owe tax on every day, including the first 14.
- State room occupancy excise: 5.7% of rent (including cleaning and booking fees).
- Local taxes on top, if your town has adopted them: a local excise of up to 6% (6.5% in Boston), and a community impact fee of up to 3%. The fee applies to "professionally managed" units (an operator with 2 or more units in a town, other than units in the owner's own 1 to 3 family home) and, by separate vote, to units in an owner-occupied 2 or 3 family house. Barnstable County towns add 2.75% for a regional water fund.
- Insurance: at least $1 million liability coverage per unit, unless the booking platform provides equal coverage (c. 175, §4F).
Towns may go further (c. 64G, §14). They can require local licenses and inspections, cap the number of days or units, limit where rentals are allowed, or ban them entirely.
