Maine rental law is short, old-fashioned, and surprisingly tenant-friendly in a few specific spots: a statutory 15-day late-fee grace period, double damages on wrongfully held deposits, and, since January 2025, a hard limit on what you can collect at move-in. Most of it lives in Title 14 of the Maine Revised Statutes, and most compliance failures trace back to not knowing three or four numbers. Here they are, then the detail.

Maine's 60-second compliance check

  • Security deposits are capped at two months' rent (14 M.R.S. § 6032).
  • Return the deposit within 30 days under a written lease, or 21 days for a tenancy at will (14 M.R.S. § 6033).
  • Wrongful retention costs you double the amount withheld plus attorney's fees (14 M.R.S. § 6034).
  • Late fees max out at 4% of one month's rent, and rent isn't legally late until 15 days past due (14 M.R.S. § 6028).
  • Entry requires reasonable notice; 24 hours is presumed reasonable (14 M.R.S. § 6025).
  • Rent increases need 45 days' written notice, or 75 days if the increase hits 10% or more (14 M.R.S. § 6015).
  • Nonpayment eviction starts with a 7-day notice once rent is 7 days behind (14 M.R.S. § 6002).
  • At move-in you may collect only first month's rent, the deposit, and disclosed mandatory recurring fees (LD 1490, effective January 1, 2025).

The Maine quick-reference page keeps these numbers current if you just need the cheat sheet.

Deposits: two months max, and the 21-day trap for at-will tenancies

Two months' rent is the ceiling (14 M.R.S. § 6032). The clock on returning it depends on paperwork you chose at the start: written lease, 30 days; tenancy at will (no written term), 21 days from termination or surrender, whichever is later (§ 6033). Plenty of Maine landlords run at-will tenancies out of habit and then miss the shorter deadline.

If you withhold anything, send a written statement itemizing the reasons within that same window. Normal wear and tear is never deductible. Miss the deadline or withhold badly and § 6034 makes it expensive: the tenant sends a 7-day demand, and wrongful retention after that means double the amount withheld plus reasonable attorney's fees and costs. The full chapter is short; read § 6033 on the Legislature's site.

Two housekeeping rules: keep deposits out of your operating funds (they're held in trust for the tenant, 14 M.R.S. § 6038), and note that Maine, unlike Massachusetts next door, does not make you pay interest on them.

Rent increases, the 75-day tier, and the new move-in fee limits

Maine has no statewide rent cap, but it regulates timing hard. Any rent increase (or increase to a mandatory recurring fee) needs at least 45 days' written notice. Cross 10%, in one jump or cumulatively within 12 months, and the notice stretches to 75 days (14 M.R.S. § 6015, tightened in 2023). Waivers are void, and collecting rent on a defective notice means refunding it with interest plus the tenant's attorney's fees.

Portland is its own world: the city's voter-passed rent control caps annual increases at 70% of regional CPI (2.5% for 2025, 2.2% for 2026), lets landlords bank unused headroom up to a 10% yearly maximum, and requires registration with the Housing Safety Office. If you own in Portland, the city's rent board rules control before state law does.

Since January 1, 2025, move-in charges are capped too: first month's rent, a security deposit up to the two-month limit, and mandatory recurring fees you disclosed in a signed total-cost document. Screening charges are allowed only at the actual cost of the background or credit check, and the applicant gets a copy of the report (LD 1490, PL 2023, c. 594). The days of padding move-in with admin and processing fees are over.

Late fees follow the strictest small-print rule in New England: no more than 4% of one month's rent, never assessed before rent is 15 days late, and only enforceable if you disclosed the fee in writing when the tenancy began (14 M.R.S. § 6028). On $1,500 rent, that's a $60 ceiling, starting day 16.

Entry: 24 hours is the Maine default

Except in emergencies, give reasonable notice before entering to inspect, repair, or show the unit; 24 hours is presumed reasonable (14 M.R.S. § 6025). The statute's emergency concept is broad enough to cover a pet in distress, not just burst pipes.

Enter unlawfully, or keep demanding entry in a harassing way, and the tenant can recover actual damages or $100 (whichever is greater), an injunction, and attorney's fees after a contested win. Cheap to comply, annoying to litigate.

The 7-day notice and Maine's forcible entry and detainer process

Evictions run through the forcible entry and detainer (FED) docket in District Court. The notice ladder under 14 M.R.S. § 6002:

  • Nonpayment: once rent is 7 or more days in arrears, serve a 7-day written notice that states the amount owed and the required cure language. Full payment before the notice expires voids it, and the tenant can still reinstate afterward by paying all arrears plus your actual filing and service costs before the writ of possession issues.
  • Serious cause: the same 7-day notice covers substantial damage, nuisance, unsafe conditions, violence, or unauthorized occupants.
  • No-fault (tenancy at will): 30 days' written notice, expiring on or after a date through which rent is paid. Fixed-term leases simply end on their own terms.

After a landlord judgment, the writ of possession follows a short waiting period (about a week), and only a sheriff can execute it. Lockouts, utility shutoffs, and door-removal shortcuts are unlawful evictions under 14 M.R.S. § 6014 and generate damages plus attorney's fees. Also assume any eviction filed within six months of a tenant's code complaint will face a retaliation presumption. Maine-specific notice forms are in the forms library.

Habitability, heat, and the disclosures Maine actually checks

Every Maine rental carries an implied warranty of fitness for human habitation (14 M.R.S. § 6021). Two teeth worth knowing: the unit's heating system must be able to hold a safe temperature (Maine treats inadequate heat as a condition violation, and utility shutoffs in winter draw regulator attention fast), and tenants can use repair-and-deduct for genuine defects, up to $500 or half a month's rent, whichever is greater, after proper written notice (14 M.R.S. § 6026).

Disclosure paperwork is where out-of-state owners slip. Maine requires, at or before lease-up:

  • Radon: test the building (every 10 years for existing buildings; within 12 months of first occupancy for buildings constructed after March 1, 2024) and give written results to current and prospective tenants (14 M.R.S. § 6030-D).
  • Bedbugs: disclose current or adjacent-unit infestations and answer inspection-history requests (14 M.R.S. § 6021-A).
  • Energy efficiency: the state energy efficiency disclosure form for units where the tenant pays utilities (14 M.R.S. § 6030-C).
  • Smoking policy: written notice of whether and where smoking is allowed (14 M.R.S. § 6030-E).
  • Lead: for pre-1978 buildings, the federal lead-paint disclosure and EPA pamphlet, one federal rule that follows you into every state.

What changed in 2023 to 2025 (and what didn't)

Maine's recent changes came in two waves. In 2023, the Legislature added the 75-day notice tier for 10%-plus rent increases (PL 2023, c. 388). In 2024 it passed LD 1490 (PL 2023, c. 594), the move-in fee and total-cost disclosure law, effective January 1, 2025, which also extended the 45-day notice rule to mandatory recurring fees and reined in screening charges.

The 2025 to 2026 sessions produced no comparable statewide overhaul of the core numbers: deposits, late fees, entry, and the 7-day notice all stand as written above. Portland's rent cap resets every September (2.2% for 2026), so recheck it annually.

Maine landlord FAQ

Can I charge an application fee in Maine?

Only the actual cost of the background or credit check, and the applicant gets a copy of the report. Since January 1, 2025, anything you collect at move-in beyond first month's rent, the deposit, and disclosed mandatory recurring fees is unlawful under LD 1490.

When can I start charging a late fee?

Day 16. Rent isn't legally late until 15 days after the due date, the fee tops out at 4% of one month's rent, and it's only collectible if you disclosed it in writing at the start of the tenancy (14 M.R.S. § 6028).

How fast can I evict for nonpayment?

Wait until rent is 7 days behind, serve the 7-day notice, then file FED if it expires unpaid. Court timing varies by docket, and the tenant can reinstate by paying arrears plus your filing and service costs any time before the writ issues.

Do I owe interest on security deposits?

No. Maine caps and deadlines deposits (§§ 6032 to 6034) but has no interest requirement, unlike Massachusetts. Keep the money in trust and separate from your own funds.

Is there a winter eviction ban in Maine?

No seasonal ban exists; the FED process runs year-round. What you can never do, in any season, is shut off heat or utilities to push a tenant out; that's an unlawful eviction under § 6014.
