Maine Pet and ESA Laws: The Landlord and Tenant Guide

Animals in a Maine rental fall into two very different legal buckets, and confusing them is where most landlord liability arises. An ordinary pet is governed by the lease and Maine law, so a landlord may set pet rules, charge a pet deposit inside the state’s deposit cap, and charge pet rent. A service animal or emotional support animal is not a pet under the federal Fair Housing Act or the Maine Human Rights Act, so the pet rules, fees, breed limits, and weight limits simply do not apply to it. Maine caps the total security deposit at two months’ rent under Title 14, Section 6032, sets no statutory limit on pet rent after the 2025 pet-fee bill failed, and bars every fee for an assistance animal. This guide walks the whole framework so you can stay compliant.

Below you will find how Maine treats pet deposits, pet fees, and pet rent for an actual pet, why the Maine Human Rights Act defines an assistance animal more broadly than federal law, the single federal rule that an assistance animal is not a pet, the two questions allowed for a service animal, the documentation you may and may not request, the corrected civil penalty for misrepresenting an animal, when you may deny a specific animal, and a step-by-step compliant process for both landlords and tenants. Where the analysis touches deposits, the details ride on the Maine security deposit laws.

Because the housing analysis turns on one distinction, the safest posture for a landlord is to run two separate tracks: a written pet policy for actual pets, and a reasonable-accommodation process for every assistance-animal request. The strongest position for a tenant is to know that a service animal or emotional support animal cannot be charged a pet deposit, a pet fee, or pet rent, and cannot be met with a breed or weight limit. Treat every figure and rule here as a starting point and verify the current law before you charge, pay, or dispute anything.

Before the Maine-specific rules, landlords must understand that assistance-animal law is primarily federal. Three statutes create overlapping obligations for every rental property owner in the country, and none of them can be overridden by a state statute, a city ordinance, a homeowners-association covenant, or a lease clause. State law can add protection on top of federal law, but it cannot subtract from it. The Fair Housing Act, at Title 42 of the United States Code, Section 3601 and following, prohibits disability discrimination in housing, including through the refusal to make a reasonable accommodation. This is the primary source of emotional-support-animal protection and reaches virtually all rental housing, from apartments to single-family rentals to condominiums.

The Americans with Disabilities Act, at Title 42 of the United States Code, Section 12101 and following, covers service animals in places of public accommodation, such as a rental office lobby, a leasing tour area, or a pool or gym open to the public. It does not govern emotional support animals, because the Act’s definition of a service animal specifically excludes a comfort-only animal. Section 504 of the Rehabilitation Act, at Title 29 of the United States Code, Section 794, prohibits disability discrimination by programs that receive federal financial assistance, which reaches public housing, the housing-choice-voucher program, tax-credit properties, and any housing that has received Department of Housing and Urban Development funding.

The Department of Housing and Urban Development once interpreted the Fair Housing Act’s assistance-animal rules in Notice FHEO twenty twenty dash zero one, issued January twenty-eight, twenty twenty. Neither that notice nor the 2013 guidance it replaced states the federal position any longer: both were rescinded on September seventeen, twenty twenty-five, and the rescission was permanently reconfirmed in HUD’s Office of Fair Housing and Equal Opportunity enforcement memorandum of May twenty-two, twenty twenty-six. Neither should be cited as the documentation standard. Maine is the state where this matters least, because 5 M.R.S. Section 4553(1-H)(A) defines an assistance animal, for the housing subchapter, as an animal a physician, psychologist, physician associate, nurse practitioner, licensed social worker, licensed professional counselor or other licensed health professional with knowledge of the disability-related need has determined necessary to mitigate the effects of a disability — with no training requirement at all. That definition is freestanding Maine law, it reaches an untrained emotional support animal on its own express words, and a federal enforcement memorandum cannot amend it. The Fair Housing Act does carry narrow exemptions, but they are narrower than most landlords assume and they never switch off Maine’s own fair-housing law.

Maine does not just mirror the federal floor; it goes further. The Maine Human Rights Act, whose housing provisions sit at Title 5, Section 4581 and following of the Maine Revised Statutes, independently forbids disability discrimination in housing and independently requires a reasonable accommodation for a service animal or emotional support animal. It is enforced by the Maine Human Rights Commission, a state agency that investigates housing-discrimination complaints separately from the federal Department of Housing and Urban Development. That means a Maine tenant denied an accommodation has a state remedy in addition to the federal one, and the state law reaches some housing that a federal exemption would leave uncovered.

The most important Maine-specific point is the definition. Under Title 5, Section 4553 of the Maine Human Rights Act, an assistance animal is either an animal that has been determined necessary to mitigate the effects of a physical or mental disability by a physician, psychologist, physician assistant, nurse practitioner, or licensed social worker, or an animal individually trained to do work or perform tasks for a person with a disability. In housing, a person with a disability is entitled to the assistance of either a service animal or an assistance animal. That definition is broader than the federal service-animal definition in two ways: it is not limited to dogs, so a cat, a bird, or another animal can qualify, and it expressly names the range of licensed providers whose determination supports the animal.

For a landlord, the practical effect is that the animal category is wide and the provider list is generous. A letter from a licensed clinical social worker or a nurse practitioner is as valid as one from a psychiatrist, and the animal need not be a dog. For a tenant, the effect is that Maine’s protection does not depend on the narrow federal service-animal box; the assistance-animal path under the Maine Human Rights Act is available whenever a qualifying provider has determined the animal is necessary to mitigate a disability. Because the state and federal standards run in parallel, the safest reading for either side is to apply whichever rule offers more protection, which in Maine is usually the state one. For a closer look at the emotional-support side of that definition, see our emotional support animal guide.

Pet deposits, pet fees, and pet rent are the most common daily flashpoint between landlords and tenants, and the single most common reason tenants file fair-housing complaints. The rules break into two very different tracks depending on whether the animal is a pet or an assistance animal. For an actual pet, Maine’s overall security-deposit framework caps the total a landlord may collect at two months’ rent under Title 14, Section 6032 of the Maine Revised Statutes. Any money collected up front, no matter what the landlord calls it, is generally treated as part of that security deposit under state law.

Maine law does not separately regulate pet deposits, so all deposits combined must fit within the two-month cap. In practice, the dollar amounts Maine landlords actually charge track the local rental market rather than any statutory number. A typical Maine pet deposit runs from about two hundred to five hundred dollars per pet in smaller markets and can reach seven hundred fifty dollars or more in higher-rent areas, but those are market figures, not legal limits, and the total deposit still may not exceed the two-month cap. The lease should clearly identify what any pet charge covers and whether it is refundable, because a deposit labeled nonrefundable without more is often unenforceable under Maine deposit law.

Pet rent is a separate concept from a pet deposit. A pet deposit is a one-time sum held against future damage; pet rent is an ongoing monthly charge paid with the rent. Maine does not cap pet rent, so market-rate pet rent in Maine commonly runs from about twenty-five to seventy-five dollars per month per pet, with higher-end properties sometimes charging more. Because pet rent is ongoing income rather than money held, it generally does not count toward the security-deposit cap. A landlord who prefers predictable recovery often structures the pet charge as a modest nonrefundable cleaning fee tied to end-of-tenancy carpet or unit cleaning, plus monthly pet rent, rather than a large refundable pool. The accounting for any lawful pet deposit follows the same rules as every deposit in the Maine security deposit laws.

The short answer is no: Maine has no statutory cap on pet deposits or pet rent. This point deserves its own section because several widely read websites report otherwise, and a landlord or tenant who relies on those pages will get the law wrong. In the 2025 legislative session, the 132nd Maine Legislature considered Legislative Document eight twenty-four, titled An Act Regarding Pet Fees in Rental Housing, also numbered Senate Paper three forty-two. The bill would have capped a one-time refundable pet deposit at three hundred dollars, limited monthly pet rent to 1% of the total rent, and barred other pet-ownership fees, while expressly exempting service and assistance animals.

That bill did not become law. After a public hearing before the Committee on Housing and Economic Development, the bill received an Ought Not to Pass recommendation under Joint Rule three ten on April thirtieth, twenty twenty-five, and died in committee. Because the bill failed, none of its numbers are Maine law. There is no three-hundred-dollar pet-deposit cap and no one-percent pet-rent cap in Maine. Pet deposits and pet rent for an actual pet remain governed by the lease and by the general two-month security-deposit ceiling under Title 14, Section 6032, not by any pet-specific statutory limit.

Why does this matter so much? Because at least four popular landlord and tenant websites describe the failed bill’s numbers as if they were enacted law, telling readers that Maine caps pet deposits at three hundred dollars and pet rent at 1% of rent. They do not. If you have read that a Maine pet deposit is capped at three hundred dollars, that page is describing a bill that failed, not the law. Always confirm a claimed statutory cap against the actual Maine statute or the Legislature’s bill status before you rely on it, and treat any figure attributed to Legislative Document eight twenty-four as a proposal that never took effect.

Breed restrictions are among the most heavily litigated parts of rental pet policy, and three legal layers interact: whether the state preempts local breed-specific rules, what a private landlord may do in a lease, and the absolute overlay that a breed restriction cannot reach a verified assistance animal. Maine has no statewide breed-preemption statute of the kind that some states use to bar cities from banning specific breeds, and preemption in any event usually targets government bans rather than private lease terms. So a private Maine landlord may generally impose a breed or weight restriction on ordinary pets.

Common private restrictions target so-called dangerous breeds, such as pit bull types, Rottweilers, Doberman Pinschers, German Shepherds, and wolf hybrids, and sometimes large dogs or specific weight classes. Landlords typically cite an insurer&#
