Short-Term Rental Regulations
in Middlesex County, MA

Airbnbs are effectively legal in Middlesex County, MA because there are no specific short-term rental regulations on the books. Short-term rentals are defined by the state as stays of 31 consecutive days or less. Local municipalities within the county typically require the unit to be the operator's primary residence and may limit rentals to 90 days per year if the host is not present (e.g., Somerville). Operators should still verify HOA rules, state-level requirements, and any tax-collection obligations. See the official source linked on this page for full requirements. Last verified 2026-05-14.
