How much notice is required to raise the rent in Maine?
Maine landlords must give at least 45 days' written notice before any rent increase takes effect — and at least 75 days' written notice if the increase is 10% or more, a tier added effective October 25, 2023 that also catches multiple smaller increases adding up to 10% within 12 months.
Since January 1, 2025 the same 45-day notice applies to increases in mandatory recurring fees, and a written or oral waiver of these rules is void; a violating landlord must return the sums collected with interest plus the tenant's attorney's fees. Rent may never be increased while the unit is in violation of the warranty of habitability, unless the tenant caused the problem. Maine has no statewide rent control and no limit on how often or how much rent can rise (with proper notice), but it is one of the few states with no preemption of local rent control: Portland has run voter-initiated rent control since 2021 — capped at a published annual percentage (2.2% for 2026), once per 12 months, with 90 days' notice — and South Portland has a rent stabilization ordinance for larger portfolios, so landlords must check city law too.
Maine rent increase notice at a glance
| Notice — month-to-month | 45 days |
|---|---|
| Varies by increase size | Yes — an increase of 10% or more requires at least 75 days' written notice (14 M.R.S. §6015(2), added by PL 2023, c. 388, eff. 2023-10-25). Anti-stacking rule: if multiple increases within a 12-month period add up to 10% or more, the 75-day notice is required before the increase that crosses the 10% line. The 75-day tier (only) does not apply to deed-restricted affordable housing or units under landlord- or tenant-side housing-program subsidy restrictions. |
| Fixed-term leases | §6015 applies to 'residential estates' generally, not just at-will tenancies — the 45/75-day written notice governs any residential rent or mandatory-recurring-fee increase. During a fixed term, rent cannot be raised at all unless the lease itself so provides (contract law); at renewal the §6015 notice periods apply. Separately, §6016 bars any rent increase while the unit violates the implied warranty of habitability (unless the violation was caused by the tenant), with waiver void and restitution plus interest and attorney's fees for violations. |
| Statewide rent control / stabilization | No |
| Rent control details | No statewide rent control or percentage cap (§6016's habitability bar is a condition on increases, not a cap). Maine does NOT preempt local rent control: Portland has operated voter-initiated rent control since 2021 (Portland City Code ch. 6, secs. 6-231 to 6-239) — annual Allowable Increase Percentage published each September 1 (2.2% for calendar 2026), one increase per 12 months, +5% of base rent on voluntary turnover, banked increases, a hard 10% ceiling per increase, Rent Board review, and 90 days' written notice, plus a local one-month deposit cap and application-fee ban. South Portland has a council-enacted rent stabilization ordinance (March 2023; 10% annual cap for buildings of 16+ commonly owned units; sunsets 2030). The former state enabling chapter (30-A ch. 167, 'Municipal Rent Control') was repealed in 1995 with nothing enacted in its place; municipalities act under home rule (30-A §3001). |
| Local rent control preempted | No |

How this record was verified: Direct read of statute text on the official Maine Revisor of Statutes site (legislature.maine.gov): sections 6032, 6033, 6034, 6038, 6015, 6028, and 6025 of Title 14 each read twice in independent formats (the HTML section page and the Revisor's official section PDF, read verbatim), with every load-bearing figure matching (2-month deposit cap; 30-day-maximum/21-day return split with the later-of trigger; forfeiture rule; double damages with 7-day pre-suit notice and landlord burden; separate-bank-account rule with $500/one-month remedy; 45-day and 75-day/10% rent-increase notices with 12-month aggregation; 4% late-fee cap, 15-day late definition, and written-notice-at-inception duty; 24-hour reasonable-notice presumption with emergency/impracticable exception). PL 2023, c. 594 (LD 1490) was additionally reconciled against the enrolled chapter law PDF, which pins 'Sec. 13. Effective date. This Act takes effect January 1, 2025.' Supporting sections read once (6031, 6035, 6036, 6037, 6039, 6000, 6016, 6022-A, 6030-I, 6030-J, 6002) plus full chapter listings of ch. 709 subch. 1, ch. 710, and ch. 710-A as the sweep basis for verified negatives (no deposit interest, no other late-fee or entry provision, no rent-increase frequency limit, no preemption statute). Preemption checked via Title 30-A: former ch. 167 'Municipal Rent Control' (30-A sections 3601-3606) confirmed repealed by PL 1995, c. 194 with nothing enacted in its place, home rule under 30-A section 3001; Portland's active rent control ordinance verified from the City of Portland's own Rent Control FAQ (version 2025.10.24, Portland City Code ch. 6, secs. 6-231 to 6-239; 2026 allowable increase 2.2%). Bill checks on official status pages: LD 1534 (municipal rent-stabilization enabling) died Ought Not to Pass 2025-05-27; LD 1765 enacted as PL 2025, c. 365 (2025-06-18, mobile home park licensing/model-ordinance only); 132nd Legislature adjourned sine die 2026-04-29. Main-session supplement (2026-07-11): the full Second Regular Session public-laws list (chapters ~500-775) was swept via the Revisor's Laws of Maine service; one on-topic enactment found and flagged as pending — PL 2025, c. 767 (LD 2176), which raises the section 6025(3) entry-violation minimum recovery from $100 to $250 and enacts section 6025-B (tenant personal-information disclosure ban), effective 90 days after the 2026-04-29 adjournment (2026-07-28), so NOT in force at this verification. Two manufactured-housing acts (PL 2025, c. 688 and c. 691) checked and confirmed out of v1 scope (lot-tenancy notice/mediation and park-sale machinery; no hard rent caps).
