Maine Landlord Responsibilities: Habitability, Disclosures, and Deposits

A Maine landlord’s core responsibilities are to deliver a habitable unit, provide specific safety equipment and written disclosures before the lease is signed, handle security deposits and rent increases on fixed timelines, and use the courts rather than self-help to end a tenancy. Most of these duties come from Title 14 of the Maine Revised Statutes, with fire safety rules in Title 25 and anti-discrimination protections in the Maine Human Rights Act. Missing any of them can mean a forfeited deposit, a court-ordered repair, or damages payable to the tenant.

Keep the Unit Fit to Live In

Every residential rental in Maine carries an automatic warranty of habitability, and a lease cannot waive it.¹ That means working plumbing, potable water, functioning electrical systems, and a structurally sound building with weather-tight roof, walls, and floors. When a tenant reports a defect that affects health or safety, the landlord must address it within a reasonable time.

The heating standard is unusually specific. The system must be capable of maintaining at least 68°F, measured three feet from exterior walls and five feet above the floor, when it is minus 20°F outside.¹ If heat, water, or electricity fails and the landlord does not fix it, a tenant can file in District Court for repairs or a rent reduction.

Install and Maintain Smoke and Carbon Monoxide Detectors

At the start of every new tenancy, smoke detectors must be installed and working in each unit of a multifamily building.² Carbon monoxide detectors must be placed in each area within or giving access to bedrooms, and in multifamily units they must run on the building’s electrical service with battery backup, use a nonreplaceable 10-year battery, or use a replaceable battery in a device with low-power wireless communication or low-frequency audible alerts.³

Once the tenant is in, routine upkeep (fresh batteries, periodic testing, not disabling the device) shifts to them. The landlord’s duty revives on written notice of a defect. A landlord who inspects detectors at installation and before each new occupancy has some liability protection, but that protection evaporates if they get actual notice of a defect and fail to act within 24 hours.³

Test for Radon and Act on the Results

Landlords of residential rentals must have an initial radon air test performed and retest every ten years. Buildings that began operating after March 1, 2014 must be tested within twelve months of tenant occupancy, and testing has to be done by someone registered with the Department of Health and Human Services.⁴

If results come back at 4.0 picocuries per liter or above, the landlord has six months to bring the level below that threshold using a registered mitigation professional, then give tenants written notice confirming the work. Results must be shared with prospective tenants before they sign a lease or pay a deposit, and existing tenants must receive written results within 30 days of the landlord getting them from the lab. Skipping any part of this process is a civil violation of up to $250 per offense.⁴

Respond to Bedbug Reports

When a tenant reports a possible bedbug infestation in writing or verbally, the landlord has five days to inspect. If bedbugs are confirmed, the landlord must contact a pest control agent within ten days and hire an insured professional to treat the problem, paying for both inspections and treatment unless the tenant caused the infestation.⁵

Before renting any unit, the landlord must tell prospective tenants whether any adjacent unit is currently infested or being treated. On request, the landlord must also share the date the unit or adjacent units were last inspected and found clear.⁵ Failure to disclose can give a tenant grounds to challenge the lease.

Give Notice Before Lead-Paint Work

For buildings constructed before 1978, a landlord performing or hiring out any repair, renovation, or remodeling that could disturb lead-painted surfaces must notify tenants at least 30 days in advance. Notice goes two ways: a sign posted on exterior entry doors and a certified mailing to every unit.⁶

The 30-day window can be shortened only with a written waiver from an adult tenant in each affected unit, and the waiver has to use specific boldface language warning about lead dust. Emergency repairs are exempt. Federal lead-paint disclosure rules also apply at lease signing for any pre-1978 property.⁶

Make the Required Pre-Lease Disclosures

Several disclosures must be done before the tenant signs or pays a deposit. Missing them can mean penalties or give the tenant a basis to leave.

Total Price Disclosure

Landlords must provide a written, plain-language breakdown of every cost the tenant will owe: total rent, mandatory recurring fees, optional recurring fees, utility service costs, and any other charges. Both parties sign it, and if actual utility figures are not available, a completed energy efficiency disclosure can fill that slot. The only exception is a lease with no mandatory or optional recurring fees beyond rent.⁷

Energy Efficiency

Tenants who will pay their own energy bills must receive an energy efficiency disclosure statement, signed by both sides, giving a picture of likely heating and cooling costs based on the building’s insulation and construction.⁸

Smoking Policy

Before the tenancy begins, the landlord must provide a written smoking policy stating whether smoking is banned entirely, allowed everywhere, or permitted only in specified areas. If limited, the notice must identify exactly where.⁹

Handle Security Deposits by the Clock

A security deposit cannot exceed two months’ rent, furnished or unfurnished.¹⁰ It must be held in a bank or financial institution account kept beyond the reach of the landlord’s personal creditors, a foreclosing lender, or a bankruptcy trustee. If a tenant asks for the name of the institution and the account number, the landlord must provide it.¹¹

Return deadlines are strict. With a written lease, the landlord has up to 30 days (or less if the lease says so) to return the deposit or deliver a written statement of deductions. For a tenancy at will, the deadline is 21 days after the tenancy ends or the tenant surrenders the unit, whichever is later. Deductions are limited to actual damage beyond normal wear and tear, or unpaid rent. Maine does not require interest on deposits held during the tenancy.¹²

Miss the deadline and the landlord forfeits the right to withhold anything, even for legitimate damage.¹²

Charge Rent and Raise It by the Rules

Rent is not late in Maine until more than 15 days after the due date. A lease clause shortening that grace period is unenforceable. Once rent crosses day 15, the maximum late fee is 4% of one month’s rent, charged once per occurrence, and it is enforceable only if the lease gave written notice of the potential charge when the tenant signed.¹³

Rent increases require advance written notice, and the required lead time depends on size. Under 10%, at least 45 days. At 10% or more, including cumulative increases within a 12-month period that reach that threshold, the notice period jumps to 75 days. Mobile home parks require 90 days for all rent and fee increases. These notice periods cannot be waived, orally or in writing.¹⁴

Give Notice Before Entering

Entry for repairs, inspections, or showings requires reasonable advance notice to the tenant. The statute presumes 24 hours is reasonable, and entry should occur at reasonable times for legitimate purposes.¹⁵

Two situations excuse the notice: a genuine emergency (the statute specifically includes situations where an animal’s welfare is at risk) and situations where notice is simply impracticable. If the tenant has changed the locks without providing a duplicate key, the landlord may use reasonable means to gain emergency entry.¹⁵ Entering without proper notice outside those exceptions can lead to claims of trespass or breach of quiet enjoyment.

End a Tenancy Through the Courts, Not Self-Help

For a tenancy at will, either side can end the agreement with at least 30 days’ written notice, no reason required.¹⁶

When there is cause, a 7-day notice to quit is available. The landlord must be able to show, through affirmative proof, one of these grounds:

The tenant, their family, or a guest caused substantial unrepaired damage.
The tenant permitted the unit to become unfit for habitation or violated the law regarding the tenancy.
The tenant is seven or more days behind on rent.
The tenant is the perpetrator of domestic violence, sexual assault, or stalking, and the victim is also a tenant.
The tenant or their guest committed violence, threats of violence, or sexual assault against another tenant, the landlord, or their agents.
The occupant was never authorized to be there.

The 7-day notice must state the specific ground. If the basis is unpaid rent, the tenant can reinstate the tenancy by paying all arrears, current rent due, and any filing or service fees the landlord actually incurred, as long as that payment happens before the court issues a writ of possession.¹⁶

No Lockouts, No Utility Shutoffs, No Retaliation

Self-help eviction is illegal. A landlord cannot shut off utilities, change locks, or physically block a tenant from the unit without going through the courts. The ban covers water, heat, electricity, gas, phone service, sewerage, elevator access, and refrigeration. A tenant who proves an illegal lockout or utility shutoff can recover actual damages or $250, whichever is greater, plus attorney fees and court costs.¹⁷ The attorney-fee exposure is what makes these cases genuinely expensive.

An eviction filed within six months of the tenant exercising certain rights is presumed retaliatory. Protected activities include complaining to a code enforcement body, requesting repairs in writing, filing a fair housing complaint, reporting that the tenant or their child is a crime victim, and reporting sexual harassment by the landlord.¹⁸ No eviction order can issue while the presumption stands unless the landlord rebuts it. The presumption does not apply when the eviction rests on the specific 7-day for-cause grounds or a lease violation, unless the tenant had recently asserted a right tied to rent withholding for habitability defects.

Follow Fair Housing, Including Source of Income

On top of federal protections, Maine’s Human Rights Act prohibits housing discrimination based on race, color, national origin, ancestry, sex, sexual orientation, gender identity, physical or mental disability, religion, familial status, receipt of a final protection order, and receipt of public assistance.¹⁹ That last category trips up landlords who do not expect it: refusing to rent to someone because they pay with a housing voucher or government assistance is illegal in Maine, and so is charging different rent, imposing different fees, or applying different rules based on the tenant’s income source.

Store and Notice Abandoned Property

When a tenant leaves belongings behind, the landlord cannot simply discard them. The items must go into a safe, dry, secured location. The landlord then sends written notice by first-class mail with proof of mailing to the tenant’s last known address, listing the items and warning that disposal may follow if the tenant does not respond within seven days.²⁰

If the tenant claims the property within those first seven days, the landlord must release it without conditioning return on payment of unpaid rent or fees. Storage continues for at least 14 days from the notice date to give the tenant time to pick up. If the tenant claims but does not retrieve by day 14, or never responds, the landlord has three options: condition release on payment of all arrears and storage costs, sell the property at fair market value and apply proceeds to what is owed (forwarding any surplus to the State Treasurer), or dispose of items with no market value.²⁰ Skipping the notice step removes those options and creates liability, so this is one procedure worth following to the letter.
