| Massachusetts | Banned statewide by state law, and the ban is still in force. 'No city or town may enact, maintain or enforce rent control of any kind,' except a narrow program in a municipality that accepts c. 40P. Owner compliance with that program must be voluntary after 6 months, it cannot cover owners of fewer than 10 units or units with a fair market rent above $400, and the town must pay owners the difference from general funds. There is no statewide cap on rent increases. Rent control is NOT on the November 3, 2026 state ballot. The Secretary of the Commonwealth lists nine binding statewide questions (Questions 1-8 are initiative laws and Question 9 is a referendum on the 2024 firearms law), and none of them deals with rent control or rent stabilization. The rent-control initiative (Initiative Petition 25-21, 'An Initiative Petition to Protect Tenants by Limiting Rent Increases') was challenged at the Supreme Judicial Court in Cella v. Attorney General, SJC-13893. G.L. c. 40P, §§ 3-4; Secretary of the Commonwealth, 2026 State Election Ballot Questions; Cella v. Attorney General, SJC-13893 | No interest or penalty for late rent may be charged until rent is 30 days overdue. There is no statutory dollar or percentage cap. G.L. c. 186, § 15B(1)(c) |
| New York | Local rent control/stabilization allowed. Rent stabilization covers many NYC buildings and other localities that declare a housing emergency (allowed statewide since June 15, 2019). Good Cause Eviction Law (RPL Art. 6-A, 2024) applies automatically in NYC and in localities that opt in: rent increases above the 'local rent standard' (5% + regional CPI, capped at 10%) are presumed unreasonable and eviction/non-renewal requires good cause. N.Y. RPL §§ 211, 212, 213, 214, 216 | Rent is not late until more than 5 days after the due date. Late fee capped at the lesser of $50 or 5% of monthly rent. N.Y. RPL § 238-a(2) |
| Rhode Island | No statewide rent control or cap on the amount of rent increases; only notice requirements (60 days; 120 days for month-to-month tenants over 62). R.I. Gen. Laws § 34-18-16.1 | No statutory cap or grace period. None in Chapter 34-18 |
