Maine Landlord-Tenant Laws: Complete Guide for Property Owners

Maine's landlord-tenant laws strive to balance the property rights of landlords with concrete habitability and transparency protections for tenants. While the state statutes apply broadly, landlords must also be acutely aware of local ordinances in municipalities like Portland, which enforce stricter rent control and eviction guardrails.

Key Maine Rental Laws at a Glance

Security Deposits

Maine effectively caps residential security deposits at two months' rent. However, if the tenant is 62 years of age or older, or has a verifiable disability, the deposit is capped at one month's rent.

Landlords must hold these funds in a separate bank account located in Maine to protect them from creditors. The return deadlines depend heavily on the lease type:

• Written Lease: 30 days to return the deposit and an itemized list of deductions.
• Tenancy at Will (No Lease): 21 days to return the funds.

For more detail, see our Security Deposits deep dive.

Eviction Procedures

Maine strictly prohibits "self-help" evictions (e.g., locking a tenant out or removing their property). All evictions require a Forcible Entry and Detainer court action.

The most common eviction notices in Maine are:

• 7-Day Notice to Quit: Used for severe lease violations, substantial property damage, or non-payment of rent (which is legally late 15 days after the due date).
• 30-Day Notice of Termination: Used to end a month-to-month tenancy without citing a specific cause.

For more detail, see our Eviction Process guide.

Rent Increases

While the state of Maine does not impose a rent control cap (though Portland does locally), it heavily regulates the notice heavily required to enact an increase:

• Less than 10% Increase: 45 days' written notice.
• 10% or Greater Increase: 75 days' written notice. This applies even if multiple smaller increases over a 12-month period cumulatively hit the 10% threshold.

For more detail, see our Rent Increases guide.

Required Disclosures

Transparency is a core tenet of Maine leasing law. Landlords are legally required to provide specific disclosures before a tenant signs a lease or pays a deposit:

1. Energy Efficiency: An energy efficiency disclosure statement.
2. Smoking Policy: A written policy stating whether smoking is prohibited, allowed, or restricted to specific areas.
3. Radon: Notification of any known radon hazards and the results of any previous radon tests.
4. Bed Bugs: Landlords must disclose if an adjacent unit is currently being treated for bed bugs, and cannot rent a unit they know is infested.

For more detail, see our Required Disclosures guide.

Maintenance and Habitability

Maine landlords are bound by the implied warranty of habitability, meaning units must be fit for human habitation and compliant with health codes. This includes safe heating capabilities—specifically the ability to maintain the unit at 68°F during the winter.

If a landlord fails to make a minor repair affecting habitability, tenants may utilize the "repair and deduct" law if the cost is less than $500 or half the monthly rent.

For more detail, see our Maintenance Obligations guide.

Late Fees

Maine protects tenants from aggressive late fees through a state-mandated formula. A landlord cannot charge a late fee until the rent is at least 15 days late. Furthermore, the maximum allowable late fee is strictly capped at 4% of one month's rent.

For more detail, see our Late Fees guide.

Getting Started with Compliance

Navigating Maine's property laws requires stringent tracking of notice periods—specifically the 45-day/75-day rent increase rules and the 15-day grace periods for late fees. Managing these timelines manually invites legal risk.

Landager automates compliance by tracking these specific timelines directly alongside your lease data.
