Somerville STR occupancy follows MA Sanitary Code 105 CMR 410 room-size standards, typically allowing two guests per bedroom plus additional occupants based on square footage.
Somerville STR occupancy follows Massachusetts State Sanitary Code 105 CMR 410 (State Housing Code), which requires at least 150 square feet for the first occupant and 100 square feet for each additional occupant in living space, plus minimum bedroom sizes (70 sq ft for one person, 50 sq ft per person for multiple). A common rule of thumb is two guests per bedroom, though the actual legal maximum is driven by total habitable space. Somerville may also impose stricter caps via the STR Ordinance, and the Fire Code limits occupancy based on egress capacity. STR listings must accurately reflect permitted occupancy. Exceeding occupancy limits creates health, fire, and nuisance violations and can trigger inspection, fines, and permit revocation. Children typically count toward occupancy limits depending on age and bedroom assignment.
