Somerville Code of Ordinances ch. 7, art. X § 7-254 establishes a formal registration system for short-term rentals, administered by the city's Inspectional Services Department (ISD). Anyone operating a short-term rental must obtain a certificate of registration before listing or renting a unit, which requires submitting an application, supporting documentation, a $250 fee, and passing an ISD inspection. Certificates follow an annual cycle expiring each March 31st and are tied to a specific unit, owner, and operator — meaning they do not automatically carry over if the property is sold or the operator's lease changes. The registration requirement took effect April 1, 2023, with a transitional window for operators who were already lawfully operating at that time.
Plain English — not legal advice.
Under Somerville Code of Ordinances ch. 7, art. X § 7-254, compliant operators file their registration or renewal application through ISD's online portal, submit all required documentation — including proof of primary residence, owner approval if applicable, a Massachusetts Department of Revenue certificate, and proof of insurance — and pay the $250 fee before operating or relisting. Operators generally maintain a 24/7 reachable local contact who can respond in person within two hours, and provide ISD with a link to any active short-term rental listings once a certificate is issued. Because certificates expire each March 31st and are not transferable upon sale or lease change, operators who hold the unit as lessees should track their lease end dates and submit updated proof of primary residence to ISD before that date to avoid the certificate being deemed invalid under § 7-254(g)(3).
General guidance for property managers — not legal advice for your specific situation. Consult an attorney for advice on your case.
Somerville Code of Ordinances ch. 7, art. X § 7-254 requires that any short-term rental unit in Somerville hold a valid, ISD-issued certificate of registration bearing a registration number, which means tenants and short-term occupants can ask to see that certificate number as a baseline indicator of compliance. The ordinance also requires operators to maintain a 24/7 telephone contact capable of responding in person within two hours to issues or emergencies, a protection that applies to both tenants and short-term occupants under § 7-254(b)(4). Tenants who believe a short-term rental is operating without proper registration, or that a certificate may have lapsed, can contact ISD directly or reach out to a local tenant-rights organization to understand what complaint or enforcement options may be available.
