Short-Term Rental Management in Somerville, MA

Why Guests Come to Somerville

• Tufts University. The main campus straddles the Medford and Somerville line, a short walk from Davis Square, so Commencement, move-in and campus visits pull families into Somerville's neighborhoods.
• The Green Line Extension. The Union Square branch opened on March 21, 2022 and the Medford branch on December 12, 2022, adding East Somerville, Gilman Square, Magoun Square and Ball Square stations. Much of the city is now a short walk from a train.
• Davis and Union Squares. Restaurants, music venues and the Red Line at Davis make Somerville a favored base for visitors who want to be near Cambridge and Boston without downtown prices.
• Assembly Row. The waterfront shopping and dining district on the Orange Line draws weekend visitors and business travelers.
• Next-door demand. Harvard, MIT and Kendall Square in Cambridge are a few stops away, so visiting researchers and conference guests often look in Somerville.

The Somerville Rental Year

Somerville tracks the Boston-area academic and event calendar. Spring brings campus visits and the Boston Marathon on Patriots' Day. May and early June peak with graduations at Tufts and the Cambridge universities. Summer is steady, September brings move-in, and October is busy with fall conferences and the Head of the Charles. Winter is slower for leisure guests. Because a host-absent rental is capped at 90 days a year, most Somerville hosts use those days where they count: graduation weekends, fall weekends and the dates they would be away anyway.

Short-Term Rental Rules in Somerville

Somerville's ordinance was passed in May 2019 and took effect January 1, 2020. On January 26, 2023 the City Council added a registration requirement, effective April 1, 2023. From the city's short-term rental page and Inspectional Services' application guide, read on 6 October 2026:

• What counts. A room or unit rented for fewer than 28 consecutive days. Month-to-month rentals are not covered, and hourly rentals are not allowed.
• Primary residence only. The unit must be the operator's primary residence. The city's FAQ is explicit: you cannot offer an adjacent unit, even in a building you live in.
• Renters can host. A tenant may operate with a property owner approval affidavit.
• Two types. A "Shared Unit" (you stay there while renting part of it) has no annual day limit. An "Autonomous Unit" (the whole unit while you are away) is limited to 90 days a year.
• One group at a time. Up to 10 people or two per guest bedroom, whichever is fewer, and no renting separate rooms or beds to separate parties.
• One listing per site. One listing per listing website per unit, kept consistent across sites.
• Registration. Apply through the city's Citizenserve portal. The guide sets a $250 registration fee ($50 at filing, $200 on approval) and a pre-certificate safety inspection by an ISD inspector.
• Posting. A sign inside must cover trash and recycling, parking rules, the noise ordinance and a contact who can respond in person within two hours.

What this means in plain terms: if you own a Somerville unit you do not live in, it cannot be a short-term rental. The alternative is a furnished rental of 28 nights or more, which the ordinance does not cover. The state room excise still applies through 31 nights, so 32 nights or more is outside both. Read our mid-term rentals guide for the landlord-tenant side.

State tax. The DLS report read in October 2026 lists Somerville's local excise at 6% and a 3% community impact fee in effect since July 1, 2025, on professionally managed units and units in owner-occupied two- and three-family homes. So the base is 11.7% (5.7% state plus 6% local), and 14.7% where the fee applies. See the Massachusetts room occupancy tax page and the Massachusetts short-term rental laws page.

Running a Rental in Somerville

• Parking. Guests with cars need to know the local parking rules, which you must post anyway. Many arrive by T.
• Two- and three-family houses. Much of Somerville's housing is in two- and three-family buildings; if you live in one unit, only that unit can be rented short-term, and the community impact fee may apply.
• Condos. Your condo documents can prohibit rentals even where the city allows them.
