Pet Deposits, Pet Rent & ESA Rules in Maine 2026
State pet-deposit treatment, federal Fair Housing Act assistance-animal rules, and what Maine landlords can and cannot ask.
Maine draws a hard line between an ordinary pet and an assistance animal, and the distinction controls almost every decision you make as a landlord. For a pet, you set the terms: allow it or not, charge a deposit, cap the weight, restrict the breed. For an assistance animal, the Maine Human Rights Act strips most of those levers away. Under 5 M.R.S. § 4582-A, a tenant with a disability is entitled to keep the animal even in a no-pet building, and you cannot condition that on a fee or security deposit.
Maine's definition is deliberately broad. 5 M.R.S. § 4553(1-H) covers both a task-trained service animal and an animal a licensed provider has determined is necessary to mitigate a disability, which is where emotional support animals live. That means an ESA gets the same housing protection as a guide dog, a point where state law tracks the federal Fair Housing Act rather than the narrower ADA service-animal rule. This page walks through what you can and cannot do, and the two situations where the law still lets you say no.
How Maine Treats Pet Deposits
Security deposit capped at 2 months' rent. Pet deposits count toward this cap; Maine law does not authorize a separate pet deposit allowance.
Pets vs. assistance animals: two different legal worlds
An ordinary pet is a matter of contract. In Maine you are free to run a no-pet building, charge a pet deposit or pet rent, restrict breeds and sizes, and enforce those terms through the lease. Nothing in state law requires you to allow pets, and a tenant who sneaks one in against the lease can be treated like any other lease violation.
An assistance animal is a matter of civil-rights law, and the analysis flips entirely. Once a tenant with a disability requests to keep an assistance animal, you are dealing with a reasonable accommodation request under the Maine Human Rights Act and the federal Fair Housing Act, not a pet request. Your no-pet policy does not apply, your pet deposit does not apply, and your breed or weight limits do not apply. The animal is not legally a pet at all. The only questions left are whether the tenant qualifies and whether one of the narrow denial grounds is met.
The no-fee rule, and why you keep your damage remedy
This is the provision landlords most often get wrong. 5 M.R.S. § 4582-A states plainly that “the use of an assistance animal may not be conditioned on the payment of a fee or security deposit.” You cannot charge a pet deposit, monthly pet rent, a one-time pet fee, or a higher security deposit because of the animal. Doing so is itself a form of housing discrimination that the Maine Human Rights Commission can act on.
What you do keep is your remedy for actual harm. The same statute makes the tenant liable for any damage the assistance animal does to the premises or facilities. You cannot collect for that damage up front through a deposit, but you can charge for it after the fact against the ordinary security deposit and normal damage rules, exactly as you would for any tenant-caused damage. In short: no surcharge for having the animal, full accountability for what the animal actually tears up.
What documentation you can (and cannot) ask for
You are not required to take every claim at face value, but Maine gives the tenant a low bar to clear. Where the disability and the disability-related need for the animal are obvious, a guide dog with a blind tenant, for example, you may not ask for any proof at all. Where the need is not obvious, which is the usual case for an emotional support animal, you may request documentation from a licensed health professional confirming the disability-related need.
Maine's definition at 5 M.R.S. § 4553(1-H) ties that documentation to a real clinician, a physician, psychologist, physician associate, nurse practitioner, licensed social worker, licensed professional counselor, or other licensed health professional with knowledge of the need. What you may not do is demand the tenant's medical records, insist on a specific diagnosis, require a particular form or a Maine-based provider, or reject a letter simply because it came from an online provider if that provider is genuinely licensed and has knowledge of the tenant. Overreaching on documentation is one of the most common ways a landlord turns a routine request into a discrimination complaint.
When you can still say no
The obligation is broad but not unlimited. Under § 4582-A a housing provider may refuse an assistance animal only where it can demonstrate that the specific animal: poses a direct threat to the health or safety of others; would result in substantial physical damage to the property of others; or would substantially interfere with the reasonable enjoyment of the housing.
Two things about this test matter. First, it is about the individual animal's conduct, not its category, a documented history of biting or aggression can support denial; a breed reputation or a size limit cannot. A blanket “no pit bulls” or “nothing over 40 pounds” rule is exactly what this provision overrides. Second, the burden is on you to show the threat or damage with evidence, and you must consider whether a lesser accommodation would resolve it before denying outright. Denying on a hunch, or because you simply prefer not to have animals, is not defensible.
Practical steps for the request, and the misrepresentation angle
When a request comes in, handle it as a documented accommodation matter. Ask the tenant to put the request in writing, confirm the disability-related need through a clinician letter if the need is not obvious, and respond promptly, unreasonable delay can be treated as a denial. Keep the animal on the lease as an approved assistance animal rather than a pet, note that no pet fee applies, and preserve your right to bill for damage. If you believe a denial ground applies, document the conduct or threat before acting.
Maine also gives you a tool against outright fraud: 17 M.R.S. § 1314-A makes it a civil violation to misrepresent an animal as a service animal or assistance animal. It does not let you second-guess a legitimate request, and it is not a shortcut around the accommodation process, but it does mean a tenant who fabricates a need is on the wrong side of the law. When a request is genuinely borderline or you are unsure how the rules apply, the Maine Human Rights Commission (207.624.6290) is the agency that enforces this area and can steer you before a complaint is filed.
The Cost of Mishandling a Maine ESA Request
The most common mistake in Maine ESA cases is responding with a flat denial, "no pets means no pets", instead of engaging in the interactive process. The interactive process is itself a substantive duty. A landlord who refuses to consider the request, demands more documentation than HUD permits, or imposes a pet fee on an accepted assistance animal will lose at HUD even if the underlying accommodation could have been reasonably denied on its merits.

It is general information for Maine housing providers, not legal advice. Assistance-animal disputes turn on specific facts, the nature of the disability, the animal's conduct, and the documentation provided, and are enforced by the Maine Human Rights Commission (207.624.6290, info@mhrc.maine.gov). Confirm the current statutory text and consult a Maine attorney before denying a request or acting on a specific accommodation.
Frequently Asked Questions
Can a Maine landlord charge a pet deposit for an emotional support animal?
No. Under 5 M.R.S. § 4582-A, the use of an assistance animal, which includes an emotional support animal under Maine's § 4553(1-H) definition, may not be conditioned on a fee or security deposit. You cannot charge a pet deposit, pet rent, or a pet fee. You can still charge the tenant after the fact for any damage the animal actually causes.
Does a no-pet policy apply to service animals and ESAs in Maine?
No. A no-pet policy is enforceable against ordinary pets, but it does not apply to assistance animals. Once a tenant with a disability requests to keep a service animal or ESA, it is a reasonable accommodation request under the Maine Human Rights Act and the federal Fair Housing Act, and your no-pet rule is set aside for that animal.
What documentation can I require for an emotional support animal?
If the disability and the need for the animal are obvious, you cannot ask for anything. If the need is not obvious, you may ask for documentation from a licensed health professional confirming the disability-related need, consistent with 5 M.R.S. § 4553(1-H). You may not demand the tenant's medical records, a specific diagnosis, or a particular form.
When can a Maine landlord deny an assistance animal?
Only where you can demonstrate the specific animal poses a direct threat to others' health or safety, would cause substantial physical damage to others' property, or would substantially interfere with other residents' reasonable enjoyment of the housing (§ 4582-A). The decision must rest on the individual animal's conduct, not its breed or size, and you should consider a lesser accommodation first.
Can I apply breed or weight restrictions to a service animal or ESA?
No. Breed and weight limits are valid for ordinary pets but cannot be applied to assistance animals. A denial has to be based on the individual animal's documented conduct or a demonstrated threat, not on a category rule like “no pit bulls” or a weight cap.
Is the tenant still responsible if the assistance animal damages the unit?
Yes. Section 4582-A makes the tenant liable for any damage the assistance animal does to the premises. You cannot collect a deposit up front for that risk, but you can charge the tenant for actual damage afterward under your normal security-deposit and damage rules.
