If you own rental property in York, Kittery, or Wells, and you are used to thinking about landlord-tenant law through a New Hampshire lens, Maine's rules are worth a closer look. The two states share a border and a lot of rental market overlap along the Seacoast, but their statutes diverge in some important ways, particularly around security deposits, rent increase notice, and new fee disclosure requirements that took effect at the start of 2025.
Understanding these differences matters if you own property on both sides of the state line, or if you are used to New Hampshire's rules and assumed Maine worked the same way.
Key Takeaways
Maine allows security deposits up to two months' rent, compared to New Hampshire's one-month cap.
Deposits must be returned within 30 days, with an itemized statement of any deductions.
A newer Maine law requires 75 days' notice for rent increases of 10% or more, and 45 days for smaller increases.
Maine now requires landlords to disclose all recurring fees in writing before lease signing, not just rent and deposit amounts.
Security Deposits: A Higher Cap Than New Hampshire
Maine landlords can collect a security deposit of up to two months' rent for most rental units, rising to three months' rent for mobile home units. This is notably more than New Hampshire's one-month cap, which matters if you manage properties in both states and want consistent policies across your portfolio.
Once collected, the deposit must be returned within 30 days after the tenancy ends, accompanied by a written itemized statement of any deductions. Unlike some neighboring states, Maine does not require landlords to hold deposits in a separate interest-bearing account or pay tenants interest on the funds, which simplifies the administrative side somewhat compared to jurisdictions with stricter escrow requirements.
Deductions are limited to unpaid rent, unpaid utility charges the tenant was responsible for, and damage that goes beyond normal wear and tear. If a landlord misses the 30-day deadline or fails to provide a proper itemized statement, they generally forfeit the right to withhold any portion of the deposit, and a tenant who successfully disputes a wrongful withholding can recover double the amount plus court costs.
New Fee Disclosure Requirements Since 2025
One of the more significant recent changes to Maine law took effect January 1, 2025, and it is worth flagging specifically because it is easy to overlook if you have not updated your lease templates recently. Maine landlords may now only charge first month's rent, a security deposit, and clearly disclosed recurring fees at lease signing. Any fees beyond those three categories must be disclosed in writing as part of a signed total price disclosure that lists every cost the tenant will be responsible for.
This law also introduced new notice requirements for rent increases. A rent increase of 10% or more now requires 75 days' written notice, while smaller increases require 45 days. This is considerably more notice than many landlords are used to providing, and missing this window can delay when an increase actually takes effect. If your lease templates or renewal process have not been updated since these changes took effect, this is worth reviewing before your next round of renewals in York, Kittery, or Wells.
Notice Requirements for Ending a Tenancy
For a month-to-month tenancy in Maine, either the landlord or the tenant generally needs to provide at least 30 days' written notice before the end of a rental period to terminate the arrangement. For nonpayment of rent or a lease violation, landlords can issue a 7-day notice to quit before moving forward with eviction if the tenant does not resolve the issue.
Maine also requires landlords to provide reasonable notice, generally understood as at least 24 hours during normal business hours, before entering a rental unit for non-emergency purposes such as repairs, inspections, or showings. Emergencies like a fire or burst pipe do not require advance notice.
Habitability and Disclosure Obligations
Maine law requires rental units to meet basic health and safety standards, and landlords are expected to make necessary repairs within a reasonable time after receiving written notice from a tenant, particularly when the issue affects health or safety. Maine also has specific disclosure requirements that go beyond what many landlords expect, including a requirement to disclose bedbug infestation history in adjacent units and any shared responsibility for common area utility costs.
Staying current on habitability standards and required disclosures is one of the areas where working with a management team that actively tracks state-specific requirements pays off, particularly for owners managing a mixed portfolio across New Hampshire and Maine where the rules genuinely differ. Our property management services are built to keep leases and notices compliant with the specific state each property sits in, rather than applying a one-size-fits-all approach across your portfolio.
FAQ
Can I charge the same security deposit amount in my Maine and New Hampshire properties?
You can, as long as it does not exceed Maine's two-month cap, but doing so may mean under-collecting relative to what Maine law allows. Many owners set deposit policy per state rather than applying a single flat amount across their whole portfolio.
Do I need to hold Maine security deposits in a separate account?
No. Unlike some states, Maine does not require deposits to be held in a separate interest-bearing account, though you must still follow the itemized deduction and 30-day return requirements.
How much notice do I need to give for a 5% rent increase in Maine?
Since the increase is under 10%, 45 days' written notice is required rather than the 75 days needed for larger increases.
Does Maine allow rent control?
Maine does not have statewide rent control, but individual municipalities can adopt their own rent stabilization ordinances. Portland has enacted local rent control measures, though York, Kittery, and Wells currently have not.
Managing Across State Lines Takes Attention to Detail
Owning property on both sides of the New Hampshire and Maine border means navigating two different sets of rules, and the gaps between them are easy to miss if you are applying the same lease template or notice process to every property regardless of location.
