Maine has rent control in Portland and South Portland, plus statewide tenant protections including a 45-day rent-increase notice. Just-cause eviction and the 12-month increase limit apply only under those local ordinances, not statewide.
Maine Rent Control at a Glance
Portland: 70% of Greater Boston CPI; 2.2% for calendar year 2026; buildings after April 2020 exempt
South Portland: verify the current allowable increase with the Rent Board; buildings after 1983 are modeled as exempt
Statewide: 45-day notice before a rent increase (14 M.R.S. § 6015); 30-day notice to end a tenancy at will. The 12-month limit and just-cause eviction are local only (Portland/South Portland).
