ESA vs. Service Animal: A Landlord's Guide (2026)

A quick note before we start. This article covers how fair housing rules generally treat service animals and emotional support animals. It isn't legal advice, and Nomad isn't a law firm. The federal rules changed in 2026, and state and local laws vary a lot, so check with an attorney licensed in your state before you deny a request, charge a fee, or write a policy around this.

Rental rules around emotional support animals shifted in 2026, and several assumptions owners have relied on for years no longer hold. In May, HUD stopped giving untrained emotional support animals the same treatment as trained service animals, which changes how you handle requests, pet fees, and denials. The Fair Housing Act statute is still intact, though, so a wrong call can still be expensive. This article covers the difference between an emotional support animal and a service animal, what changed, and how to handle a request without running into trouble.

Service animal vs. ESA vs. pet

There are three different categories and three sets of rules. Here's how housing law treats each one:

The last question around damage liability is one that is common for both tenants and property owners to misunderstand. Waiving a pet fee doesn't waive the tenant's responsibility for damage. Even when you can't charge a pet deposit, the resident still pays for any damage the animal actually causes, taken out of the standard security deposit under your state's rules.

What changed in 2026 (and what didn't)

For about twenty years, the federal rules told housing providers to treat trained service animals and untrained emotional support animals almost the same. Both counted as "assistance animals," both required a reasonable accommodation, and you couldn't charge a pet fee for either. That approach came out of guidance HUD issued in 2020.

HUD threw that out on May 22, 2026. In an enforcement memo signed by Assistant Secretary Craig Trainor, HUD's Office of Fair Housing and Equal Opportunity (FHEO) rescinded the 2020 guidance and set a new bar: FHEO will now find "reasonable cause" on a failure-to-accommodate complaint only when the animal has been individually trained to do work or tasks tied to the person's disability. That's the same training test the Americans with Disabilities Act uses. A request involving a trained animal is treated as presumptively reasonable. A request to waive a pet policy for an untrained emotional support animal isn't, and HUD says it generally won't pursue those complaints.

That being said, this was an enforcement memo, not a new law. The Fair Housing Act statute didn't change, and three things still apply:

• Private lawsuits. A tenant can still sue you directly under the Fair Housing Act whether or not HUD gets involved.

• State and local law. Plenty of states and cities have their own assistance-animal protections, documentation rules, and penalties, and several still protect emotional support animals. The federal memo leaves all of that alone.

• Section 504 protections for federally assisted housing.

So the takeaway isn't "you can deny any ESA now." It's that the federal enforcement picture loosened up, while how much risk you're actually carrying depends on your state and on whether a tenant sues. If anything, that makes it more worth your while to handle each request carefully and keep a paper trail. When you're not sure, call a local attorney instead of leaning on a rule of thumb you read online.

What is a service animal?

A service animal is an animal trained to perform a specific task for a person with a disability. Guiding someone who's blind, alerting someone who's deaf, interrupting a panic attack, retrieving dropped items, and signaling a medical emergency all count. What makes it a service animal is the trained work tied to the disability, not the comfort the animal provides just by being around.

Under the ADA, which covers public places like stores and restaurants, service animals have to be dogs, with a narrow exception for miniature horses. In housing the Fair Housing Act is broader on paper, but federal enforcement in 2026 landed on the same question the ADA asks: is the animal trained to do a task?

What is an emotional support animal (ESA)?

An emotional support animal eases a symptom of a person's disability through companionship or comfort, without being trained to do a specific task. That missing task training is the whole difference between an ESA and a service animal, and it's what the 2026 change turns on. An animal that's there for comfort, well-being, or company no longer gets presumptively reasonable treatment under HUD's enforcement standard, though your state's law may still protect it.

What is an "assistance animal"?

"Assistance animal" is the Fair Housing Act's umbrella term for any animal that works, assists, or provides a disability-related benefit. It covers trained service animals and, historically, emotional support animals too. The FHA doesn't use the ADA's narrow "service animal" definition for housing, so an owner who says "we only take trained service dogs" is quoting the wrong law. In a rental, the question is whether the animal is an assistance animal you're required to accommodate, and after 2026 that mostly comes down to whether it's trained.

Fair Housing Act vs. ADA: which one applies to your rental?

The Fair Housing Act covers housing. The Americans with Disabilities Act covers public places. Keeping those two straight will save you more trouble than almost anything else here. A restaurant deciding whether to let a dog in is an ADA question. You, deciding whether to allow an applicant's animal in a rental home, are dealing with a Fair Housing Act question. In housing, the FHA is the law that makes you consider a reasonable accommodation, both for service animals and, depending on your state, for emotional support animals.

Can a landlord charge pet rent, a pet fee, or a pet deposit for an ESA?

For a trained service animal, a property owner can't legally charge for pet rent, a pet fee, or a pet deposit. Charging for any of the three violates the Fair Housing Act, which has not changed with the 2026 memo.

However, for an untrained emotional support animal, the answer of whether you can charge a fee did change in 2026 and now depends on where you are. At the federal level, charging a pet fee for an untrained ESA is no longer a clear Fair Housing Act violation, because HUD reserves fee waivers for trained animals. But several states and cities still ban pet fees for emotional support animals under their own laws, and the federal memo doesn't touch those. Before you write a pet fee into a lease for an ESA, check your state's current rule, because this is exactly where national advice and local law tend to split.

Two things are true no matter how the fee question shakes out. First, you can always hold the resident responsible for actual damage the animal causes, taken from the standard security deposit under your state's rules. Waiving a fee never lets the tenant off the hook for damage. Second, a "no pets" policy on its own isn't enough to turn away a qualifying assistance animal, because an assistance animal isn't a pet for that purpose.

Can a landlord deny a service animal or ESA request?

Yes, in specific and limited situations, as long as the reason is about the actual circumstances and not a blanket policy. Even when a request is presumptively reasonable, fair housing rules have long let a housing provider say no when:

• The specific animal is a direct threat to the health or safety of others that you can't reduce with another reasonable accommodation, based on what that animal actually does rather than its breed or size.

• The specific animal would cause substantial physical damage to the property that you can't reduce with another accommodation.

• The accommodation would be an undue financial and administrative burden or would force a fundamental change to how you operate.

After 2026, a request to waive a pet policy for an untrained emotional support animal also isn't presumptively reasonable at the federal level, which gives owners more room than they used to have. That room is smaller than it looks, though, because a private lawsuit or a state agency can still second-guess the call. A narrow set of owner-occupied and small properties may also be exempt from some Fair Housing Act requirements, but those exemptions are easy to get wrong, so confirm one applies before you count on it. Fumbling an assistance-animal request is one of the more common and costly mistakes landlords make, so it's worth slowing down here. Your safest bet is to look at each request on its own facts, write down your reasoning, and get legal input before you deny one.

What documentation can you ask for?

Start with what you can't do. If the person's disability and their need for the animal are obvious, you can't ask for documentation at all. When the need isn't obvious, you can request documentation that reasonably supports two things: that the person has a disability, and that the animal helps with it (or, after 2026, that the animal is trained to perform a disability-related task). There is no official government ESA form and no federal registry, so "proof" means real documentation, not a card or certificate.

In practice, the documentation that counts is a letter or note from a licensed health care provider who actually treats the person, confirming the disability-related need in general terms. A doctor, therapist, or other licensed professional can write it. What you can't require: your own mandatory form, the person's diagnosis or medical records, notarization, or a fee to review the request. Several states also set their own rules on who can write the letter and how recent it has to be, so check your state before you ask. And remember the 2026 shift: documentation that shows only comfort or companionship, with no task training, no longer makes a request presumptively reasonable at the federal level, even when it comes from a legitimate provider.

Online "ESA registration" certificates, ID cards, and "registry" listings bought from a website usually aren't reliable proof of a disability-related need on their own, and no law requires a service animal or an ESA to be registered or certified. If a request rests only on a purchased certificate, you can ask for legitimate documentation instead. Whatever you decide to request, ask everyone in the same situation for the same thing, and keep a written record of what you asked and why.

For when the animal really is a pet

Plenty of applicants just have a pet, and that's a business call, not a fair housing one. About 95 million U.S. households own a pet, according to the American Pet Products Association's 2025 National Pet Owners Survey, so a strict no-pets policy quietly rules out a big slice of the rental market. Allowing pets widens your applicant pool, and how many early inquiries a listing gets tends to track with how fast it leases. Nomad's leasing data (July 2025) shows the homes that lease within a week draw more than 20 inquiries in their first week on the market, while homes that take 30 days or more usually see fewer than half that many early inquiries. A pet-friendly listing picks up more of those early inquiries, because it's open to a slice of renters that a "no pets" listing turns away. Just hold the bar where it is and screen every applicant the same way, pet or not.

Before deciding whether or not to allow pets, make sure you weigh some of the pros and cons:

None of these are automatic. A well-screened tenant with a calm, older cat is a very different risk than an unscreened one with an untrained puppy, so the lease terms and the screen do more work than the yes-or-no pet decision itself. You can manage the downsides with pet rent, a pet deposit, and clear lease language for actual pets, none of which you can apply to a qualifying assistance animal.

How Nomad handles this

Nomad is software you use to lease and manage your own homes, so you keep the decisions and the software takes care of the repetitive work. On the pet and assistance-animal side, that plays out in three places. You set your own pet policy, and the platform generates a state-specific, lawyer-vetted lease that matches it. You pick the tenant from applicants who've cleared a 10-point screen, so opening up to pets doesn't mean lowering the bar on the resident. And if a pet causes damage, Nomad treats that as a managed risk rather than a coverage gap. Pet damage isn't on the Property Protection Plan's exclusion list, so the plan can cover accidental, resident-caused damage above the security deposit that you can't recover from other insurance, up to $500,000 for structural damage, subject to the plan's terms and deductible (the plan is backed by Lloyd's of London, as of 2026). On top of that, owners who allow pets get an added pet damage reserve of up to $1,000 per pet, funded by part of the pet rent Nomad collects (as of 2026). That's the situation owners worry about most with animals: a chewed door or a stained floor that runs past the deposit.

Handling an assistance-animal request is still your call, and it's one worth taking seriously. What the software does is keep everything around it (the screening, the lease, rent, the damage coverage) routine, so the judgment call is the only hard part. Deciding how to handle pets and assistance animals is just one piece of renting out your home.

Frequently asked questions

Can a landlord charge pet rent for an emotional support animal? It depends on your state as of 2026. At the federal level, charging pet rent, a pet fee, or a pet deposit for an untrained emotional support animal is no longer a clear Fair Housing Act violation, because HUD's May 2026 standard reserves fee waivers for animals trained to do a disability-related task. But several states and cities still ban it under their own laws, which the federal change doesn't affect. For a trained service animal, you can't charge these fees. Either way, the

resident still pays for any damage the animal causes.

Can a landlord deny an emotional support animal? Sometimes, and more often at the federal level than before 2026. HUD will now generally pass on complaints about untrained emotional support animals, so a "no pets" policy carries more weight federally than it used to. But state law and private lawsuits still apply, so a denial should rest on the specific facts, like a direct threat or substantial property damage the animal would cause, and it should be documented. Get legal input before you turn a request down.

What's the difference between a service animal and an emotional support animal? A service animal is trained to perform a task for a person with a disability, like guiding, alerting, or retrieving. An emotional support animal provides comfort or companionship without that task training. The training is the whole difference, and it became the deciding factor in federal housing enforcement in 2026.

Do emotional support animals have to be registered or certified? No. No law requires a service animal or an emotional support animal to be registered, certified, or listed in any database, and online "ESA registration" certificates usually aren't reliable proof of a disability-related need on their own. What matters is legitimate documentation of the need when it isn't obvious, and, since 2026, whether the animal is trained to do a task.

Did the law about ESAs actually change in 2026? The enforcement policy changed; the statute didn't. On May 22, 2026, HUD rescinded its 2020 assistance-animal guidance in a FHEO enforcement memo and moved to a standard that treats only trained animals as presumptively reasonable accommodations. The Fair Housing Act itself is unchanged, tenants can still bring private lawsuits, and state and local protections still apply.

Is the tenant responsible for damage an assistance animal causes? Yes. You can't charge a pet deposit or pet fee for a service animal, and often can't for an ESA depending on your state, but the resident still pays for any damage the animal actually causes, taken from the standard security deposit under your state's rules.
