Attleboro, MA Short-Term Rentals: Occupancy Limits (2026)

Attleboro has not adopted a separately codified short-term rental ordinance with a per-bedroom occupancy formula. STR operators in Attleboro are subject to two layers of state regulation. First, MGL c.64G (as amended by Chapter 337 of the Acts of 2018) requires every operator of a property rented for 31 days or fewer to obtain a Certificate of Registration through the Massachusetts Department of Revenue Short-Term Rental Registry under MGL c.62C, §67. The application asks the operator to declare the unit's bedroom count and the maximum number of overnight guests, which then becomes the legally enforceable occupancy ceiling for that listing. Second, 105 CMR 410 (the State Sanitary Code, Chapter II - Minimum Standards of Fitness for Human Habitation) sets minimum sleeping-room floor areas: 70 square feet for one occupant and 50 square feet per additional occupant in any habitable room used for sleeping. 780 CMR (the Massachusetts State Building Code) defines bedrooms by minimum dimensions and requires emergency-egress windows. Attleboro's Inspectional Services and Building Department apply these state standards through housing-code inspections, and a smoke-detector and carbon-monoxide certificate of compliance is required under MGL c.148, §§26F and 26F1/2 before transfer or rental. Operators renting more than three sleeping rooms to four or more unrelated lodgers may also fall under the lodging-house statute (MGL c.140, §§22-32) and require a separate City of Attleboro lodging-house license.
