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

Leominster has not adopted a separately codified short-term rental ordinance with a per-bedroom occupancy formula. STR operators in Leominster 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 requires the operator to declare the unit's bedroom count and maximum overnight guests, which becomes the legally enforceable occupancy ceiling for the listing. Second, 105 CMR 410 (State Sanitary Code, Chapter II - Minimum Standards of Fitness for Human Habitation) sets minimum sleeping-room floor areas of 70 square feet for one occupant plus 50 square feet for each additional occupant in any room used for sleeping. 780 CMR (Massachusetts State Building Code) defines bedrooms by minimum dimensions and requires emergency-egress windows. Leominster's Building Department applies 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 to four or more unrelated lodgers may also fall under the lodging-house statute (MGL c.140, §§22-32) and require a separate Leominster lodging-house license.
