Boston · No rent cap
No cap
There's no limit on how much a landlord can raise rent in Boston: Massachusetts law bars rent control of any kind. A 2026 ballot initiative to cap increases was blocked by the state's highest court. For tenants at will, the increase needs written notice of at least a full rental period or 30 days.
Massachusetts law prohibits local rent control. A 2026 statewide rent-cap initiative was blocked from the ballot by the Supreme Judicial Court.
Recent changes
In Cella v. Attorney General (SJC-13893), the Supreme Judicial Court ruled on June 23, 2026 that the initiative petition to limit rent increases contained excluded matters in violation of art. 48, and barred it from the 2026 statewide ballot. Massachusetts law still prohibits local rent control, so Boston has no cap.

§ 1 · The law
No cap
There's no formula, because there's no cap. Chapter 40P says no city or town may enact, maintain or enforce rent control of any kind. Boston asked the Legislature for permission in a 2023 home rule petition (H.3744); in September 2024 it was sent to a study order instead. A statewide initiative that would have capped increases at CPI or 5%, whichever is lower, was certified for 2026, but the Supreme Judicial Court ordered it kept off the November 2026 ballot.
Law: No rent control: Massachusetts Rent Control Prohibition Act (M.G.L. c. 40P).

§ 3 · Timing
Notice: For a tenant at will paying monthly, the landlord must give written notice at least as long as the interval between rent days or 30 days, whichever is longer (M.G.L. c. 186 § 12). The notice may offer a new tenancy at a different rent.
Next change: No change is scheduled. The 2026 rent-cap initiative was blocked from the ballot on June 23, 2026, and Boston's home rule petition went to a study order in 2024.
