## Summary

Boston permits short-term rentals (stays under 28 consecutive days) only for owner-occupants of their primary residence, under the 2018 Short-Term Residential Rentals ordinance (Boston Municipal Code ch. 9-14, effective January 1, 2019). Investor-owned, absentee, and tenant-operated units are ineligible: an Operator must be the owner and reside in the unit at least nine of twelve months. Three unit types are allowed, each up to 365 days/year: Limited Share (a room in the owner's occupied primary residence, hosted; max 6 guests, $25/yr), Home Share (the owner's whole primary-residence unit while away; max 10 guests, $200/yr), and Owner-Adjacent (a second unit in an owner-occupied two- or three-family building; $200/yr). Registration with the Inspectional Services Department (ISD) is mandatory (BMC 9-14.6), operators must carry $1,000,000 liability insurance (G.L. c. 175 s. 4F) unless the platform provides equal coverage, and units subject to affordability covenants, leasing prohibitions, or Problem-Property status are ineligible (BMC 9-14.4A). Fines are $300/day for offering an ineligible unit and $100/day for operating unregistered (BMC 9-14.9). Booking agents (platforms) must sign data-sharing/enforcement agreements with the City, de-list unregistered or ineligible units, and report monthly, or be barred from doing business in Boston (BMC 9-14.10, 9-14.11). A Boston STR guest pays roughly 14.95% in room-occupancy taxes (5.7% state + 6.5% Boston local option + 2.75% Convention Center fee), rising to ~17.95% where the 3% Community Impact Fee applies (owner-adjacent 2-3 family units and operators with multiple units); platforms collect and remit these under G.L. c. 64G.

## At a glance

- Unhosted whole-home rental: Conditional
- Hosted rental (host present): Yes
- Primary residence required: Yes
- Guest cap: 10 guests
- Rules apply to stays under: 28 days

Notes: Whole-home unhosted rental is allowed ONLY where the unit is the owner-operator's primary residence (Home Share Unit, BMC 9-14.2/9-14.5(c), max 5 bedrooms or 10 guests, whichever is fewer) or is a single Owner-Adjacent Unit in an owner-occupied two- or three-family dwelling all owned by the same owner-occupant (9-14.5(d)). Investor/absentee whole-home rentals are prohibited. Hosted rental is a Limited Share Unit: a portion of the owner's occupied primary residence while the Operator is present, max 3 bedrooms or 6 guests (whichever is fewer), one bedroom reserved for the Operator (9-14.2). Primary Residence = Operator resides there at least 9 of 12 months, proven by 2+ documents (utility bill, voter/motor-vehicle registration, deed, lease, driver's license, or residential-exemption proof) (9-14.2). Short-Term Rental is defined as occupancy for fewer than 28 consecutive days (9-14.2); stays of 28+ days fall outside the ordinance. Note the state room-occupancy tax uses a 31-day threshold (rentals of 31+ consecutive days are exempt from the excise, G.L. c. 64G). Furnished institutional/business stays with a minimum of 10 days are not treated as short-term rentals (9-14.4B(d)). Only one owner may register as Operator per unit, and an Operator may offer only one whole-unit listing at a time (9-14.5).

## Enforcement

- Penalties: BMC 9-14.9: offering an ineligible unit as a short-term rental (or a booking agent accepting a fee for one) is fined $300 per violation per day (9-14.9(a)); operating an eligible unit without registering, or while registration is suspended, is fined $100 per violation per day (9-14.9(b)); failure to comply with a notice of violation is $100 per violation per day (9-14.9(c)). Each day is a separate violation. Enforced via the M.G.L. c. 40 s. 21D noncriminal disposition process and the M.G.L. c. 40U 'Green Ticket' law (9-14.10(a)); the Commissioner may also seek an injunction.
- Platform liability: Booking agents (platforms) must enter agreements with the City to remove listings that exceed day limits, are ineligible, or lack a valid City registration number; any booking agent that fails to enter such an agreement is prohibited from conducting business in Boston (BMC 9-14.10(b)). Booking agents must file monthly electronic reports of Boston listings, including location, room-vs-whole-unit, and nights occupied (BMC 9-14.11). Under G.L. c. 64G, the booking agent/intermediary collects and remits room-occupancy taxes.
- Notes: Ineligible units (BMC 9-14.4A): below-market/income-restricted units or those under affordability covenants; units where law prohibits leasing/subletting; units in 'Problem Properties' or 'Public Nuisance Properties' (or owned by owners of such properties); and units with 3+ violations of ch. 9-14 in six months or 3+ nuisance-type violations in six months. Units with outstanding building/sanitary/zoning/fire violations have registration suspended until cured (9-14.5(g)). Lodging houses and bed-and-breakfasts holding valid ISD certificates as of the ordinance's effective date must register but are exempt from the 9-14.5 unit limits (9-14.4B). ISD files an annual report with the City Clerk (Section 2 of the ordinance).

## Pending changes

- No material substantive amendment to Boston ch. 9-14 identified for 2024-2026; ISD registration framework and fees ($25/$200/$200) remain in force. Boston University Initiative on Cities published a November 2025 study on STR regulation, compliance, and housing impact, informing ongoing council discussion but not itself a rule change. (proposed, 2025-11-07) — https://www.bu.edu/ioc/2025/11/07/short-term-rentals-in-boston-regulation-compliance-and-impact/

## Not yet verified (we say so instead of guessing)

- State room occupancy excise stated as 5.7%: the fetched statute (G.L. c. 64G s. 3) codifies a 5% base rate; the additional 0.7% is an uncodified surtax cited by MA DOR (TIR materials) but not present in the fetched statute text. The 5.7% figure is corroborated by MA DOR TIR 01-15 (archives.lib.state.ma.us). mass.gov/info-details/room-occupancy-excise-tax returned HTTP 403 to non-interactive fetch and could not be captured directly.
- Community Impact Fee (3%) applicability to Boston STRs is verified via the MA DOR/DLS local-options report (Boston adopted at 3%, eff. 7/1/2019, with both the professionally-managed and owner-occupied 2-3 family options marked 'Yes'). The precise statutory scope is G.L. c. 64G s. 3D; that specific section text was not separately fetched.
- Business certificate (DBA) requirement is listed on the boston.gov ISD Short-Term Rentals page but its fee and renewal terms were not verified against the City Clerk's fee schedule; cost/renewal set to null.
- State DOR operator registration in the Massachusetts STR registry (via MassTaxConnect) is generally required under G.L. c. 64G but was not captured as a separate requirement because the mass.gov registration page returned HTTP 403; platforms typically register/remit on operators' behalf.
- Convention Center Financing fee's application to short-term rentals is inferred: the fee is administered as a tax under c. 64G (per TIR 01-15) and c. 64G was extended to short-term rentals effective 7/1/2019; TIR 01-15 predates the STR law and does not itself mention STRs.
