Every Somerville STR must register annually with the city, pay a fee, pass a life-safety inspection, and register with the MA Department of Revenue for room occupancy tax.
Somerville requires every STR operator to complete annual registration with Inspectional Services Division or the designated licensing office before advertising or accepting bookings. The application requires proof of ownership or long-term tenancy, proof of primary residence, proof of insurance meeting the $1M state minimum, and disclosure of the unit type and number of bedrooms. After application, Somerville conducts a life-safety inspection covering smoke detectors, carbon monoxide detectors, egress, electrical safety, and lead paint compliance for units built before 1978 where children may stay. Operators must also register with the Massachusetts Department of Revenue via MassTaxConnect to remit room occupancy tax under MGL c.64G. The registration certificate number must appear in all listings on Airbnb, Vrbo, and other platforms. Registration is not transferable and must be renewed annually. Operating without registration results in fines up to $300 per offense and potential permanent disqualification.
