No statewide rent cap
Maine has no statewide rent-increase cap, and Maine does not have state-level preemption of local rent control. That means Maine cities and counties are legally free to enact their own rent-stabilization or rent-control ordinances — but in practice, almost no Maine locality has done so. For the overwhelming majority of Maine residential rentals, the rent a landlord may charge and the annual rent increase are governed only by the written lease, market conditions, and general contract law.
That said, Maine landlords still have three statutory guardrails on rent increases: (1) proper written notice of the new rent before it takes effect — typically 30 days for a month-to-month tenancy, or whatever the lease term provides; (2) compliance with Maine fair-housing law and the federal Fair Housing Act, which prohibit rent increases targeted at protected classes; and (3) anti-retaliation protection — a rent increase issued within a short window after a tenant code complaint, fair-housing contact, or tenant-organizing activity is presumed retaliatory in most Maine jurisdictions and the landlord bears the burden of rebutting with a documented, non-retaliatory business reason. This Maine rent-control guide explains how rent increases work under current Maine law, what notice is required, what local ordinances to check before raising rent, and how to defend a rent increase against a retaliation or discrimination claim.

Maine has no statewide rent-increase cap, and Maine state law does not preempt local rent control — meaning Maine cities and counties have full legal authority to enact their own rent-stabilization or rent-control ordinances if they choose. In practice, however, most Maine localities have not enacted a local cap, and the overwhelming majority of Maine residential rentals are not subject to any rent cap from any level of government.
No Maine city or county currently has a binding rent-stabilization or rent-control ordinance on record. But the Maine legal landscape changes frequently — more than a dozen U.S. cities have enacted new rent-stabilization ordinances in the last three years, and Maine state law permits localities to follow. Confirm the current municipal code in the Maine city or county where the property is located before relying on this.
Where no local rent-control ordinance applies, rent increases on a Maine residential unit are limited only by the written lease and market conditions, subject to: proper statutory written notice (typically 30 days for a month-to-month tenancy); federal and Maine fair-housing law (no targeting of protected classes); and Maine anti-retaliation law (no increase within the statutory retaliation window after a protected tenant act). A Maine landlord contemplating a substantial rent increase in a high-turnover or gentrifying neighborhood should document the legitimate business reason (market comparables, operating-cost increases, capital-improvement passthroughs) contemporaneously and in writing, before serving the increase notice, to rebut any later retaliation or discrimination claim.
No cities in Maine currently have active local rent control ordinances in our database.
No statewide cap. Localities may enact their own rent-stabilization ordinances but few have. Increases are generally market-driven.
Typically 30 days written notice for month-to-month tenancies.
There is no state preemption, so cities may legislate locally — but most have not.
