The Fair Housing Act guarantees a tenant with a disability-related need the right to keep an emotional support animal in housing that otherwise bans pets, with no pet rent, no pet deposit, and no breed or weight limit — as long as the tenant provides reliable documentation and the animal doesn’t pose a direct threat or cause serious property damage. That’s the core rule. Everything else — what a landlord can ask, when they can say no, and what happens if they don’t comply — flows from that one guarantee.
Reasonable accommodation: the legal foundation
The FHA doesn’t mention “emotional support animals” by name. It requires housing providers to make a “reasonable accommodation” for tenants with disabilities, and courts and HUD have long treated an assistance animal as one of the most common accommodations requested. The logic: a no-pets policy is a neutral rule, but for a tenant whose disability is managed in part by an animal’s presence, that neutral rule creates unequal access to housing. Waiving it is the accommodation.
To qualify, a tenant needs two things: a disability under the FHA’s definition (a physical or mental impairment that substantially limits a major life activity) and a disability-related need for the animal. The second part is where documentation comes in — usually a short letter from a licensed provider that describes that need. The letter doesn’t have to name a diagnosis, and a landlord isn’t entitled to medical records, therapy notes, or details of the underlying condition.
This protection applies to owned, rented, and even temporary housing covered by the FHA — apartments, condos, co-ops, and most rental homes. It does not create public-access rights. An ESA that’s protected in a tenant’s apartment building still has no legal right to enter a restaurant, store, or workplace under federal law; see our breakdown of ESA vs. service dog rights for how the two categories diverge outside the home.
How requests get evaluated — and what HUD withdrew in 2025
For years the reference point was FHEO-2020-01, the assistance animal notice HUD issued in January 2020. That notice no longer stands. HUD’s Office of Fair Housing and Equal Opportunity withdrew it — along with its 2013 predecessor — effective September 17, 2025, in a withdrawal published at 91 FR 17291.
What the withdrawal did not touch is the law underneath. Congress wrote the reasonable accommodation duty into the Fair Housing Act, and HUD’s own regulation at 24 C.F.R. § 100.204 still requires a housing provider to make reasonable accommodations in rules, policies, practices, or services when necessary to afford a person with a disability equal opportunity to use and enjoy a dwelling. Guidance is sub-regulatory; a statute and a regulation are not.
In practice the assessment still turns on two questions:
- Does the person have a disability?
- Does the person have a disability-related need for the animal?
Where the disability is not obvious and the tenant supplies documentation from a licensed professional answering both, that has generally been treated as sufficient. What a tenant should no longer rely on is the withdrawn notice’s now-familiar sorting of “common household animals” against unusual species — that framework lived in the guidance, and the guidance is gone. Several states answer the species question directly in their own statutes, which is increasingly where the reliable answer sits.
What a landlord can and cannot ask
The statute, HUD’s regulation at 24 C.F.R. § 100.204, and the case law built on them give landlords a narrow, specific set of allowed questions — and a longer list of things they are barred from asking.
| Allowed | Not allowed |
|---|---|
| Ask if the animal is needed because of a disability | Ask what the specific diagnosis is |
| Ask for documentation from a licensed professional if the disability isn’t obvious | Demand medical records or therapy notes |
| Ask about the type of animal if it’s not a common household animal | Require a demonstration of the animal’s “training” (ESAs aren’t trained for tasks) |
| Deny if the animal is a direct threat or would cause substantial damage | Require the tenant to use a specific letter-writing company or online “certification” service |
| Verify the letter-writer’s professional license is genuine | Charge a fee just to process the accommodation request |
That last row matters because of how common the opposite claim is online. No government agency issues ESA “registrations” or “certificates,” and a landlord cannot require one — a real letter from a licensed professional is the only documentation the FHA recognizes, and any site selling a “certified ESA” credential is selling something with no legal standing.
Fees, deposits, and rent
Once a request is properly documented and approved, the assistance animal is legally not a pet for lease purposes, even though it lives in the unit like one. That distinction removes three charges landlords routinely apply to pets:
- Pet deposit — not allowed for an approved ESA.
- Pet rent (a recurring monthly charge) — not allowed.
- Breed or weight-based fees or bans — not allowed, including policies that exclude specific dog breeds building-wide.
A landlord can still hold the tenant financially responsible for actual damage the animal causes, the same as they could for damage from a person. What’s off the table is charging in advance for the mere presence of the animal, or applying a blanket surcharge that assumes damage will happen.
When the exemptions apply
The Fair Housing Act has two narrow exemptions that come up constantly in housing questions, and both are easy to misapply:
Owner-occupied buildings with four or fewer units. If the landlord lives in one of the units in a building with four units or fewer total, the FHA’s housing provisions generally don’t apply to that building. This is sometimes called the “Mrs. Murphy” exemption. It’s a narrow carve-out — it only covers small, owner-occupied properties, not every small landlord, and state or local fair housing laws can still apply even where the federal exemption does.
Single-family homes sold or rented without a broker. A private individual who owns no more than three single-family homes and rents one out directly — without using a real estate agent, broker, or any discriminatory advertising — can also fall outside FHA coverage for that transaction.
Both exemptions are frequently misunderstood as blanket permission to refuse any assistance animal. They’re not. They apply to a specific, limited set of housing arrangements, and many states layer their own, broader fair housing protections on top — California’s Fair Employment and Housing Act, for example, covers assistance animal accommodations more broadly than the federal exemptions allow, as explained in our California ESA housing guide.
Filing a complaint with HUD
If a landlord denies a properly documented request, charges a prohibited fee, or retaliates against a tenant for asking, the complaint process runs through HUD, not a lawsuit filed independently (though that option exists too):
- File within one year of the alleged violation, using HUD’s Fair Housing complaint form online, by phone, or by mail.
- HUD investigates, which can include contacting the landlord, reviewing the accommodation request and any denial, and interviewing both parties.
- If HUD finds reasonable cause, it can pursue conciliation between the parties or refer the case for a formal hearing, which can result in damages, injunctive relief, and civil penalties against the landlord.
- State agencies can also handle the complaint in states with a fair housing law HUD has certified as substantially equivalent, which often means a state-specific process alongside or instead of the federal one.
Keeping a paper trail — the original letter, the written request to the landlord, and any denial in writing — is what makes a HUD complaint actually enforceable rather than a word-against-word dispute.
Quick reference checklist
- Disability-related need documented by a licensed professional: required.
- Landlord can verify the license and ask the two HUD questions: yes.
- Landlord can ask for a diagnosis or medical records: no.
- Pet deposit, pet rent, or breed/weight fees for an approved ESA: not allowed.
- Owner-occupied buildings of four units or fewer: often exempt.
- Complaint window with HUD: one year from the violation.
Housing is only one piece of what an ESA does and doesn’t cover; the emotional support animal hub rounds out qualifying rules, documentation, and where the protection stops applying.
Frequently Asked Questions
Can a landlord evict a tenant for having an ESA?
Not for having the animal itself, if the request was properly made and no exemption applies. A landlord can still evict for lease violations unrelated to the animal, or if the animal causes real property damage or threatens safety.
Does the Fair Housing Act cover roommates in a shared rental?
It depends on who holds the lease. If the landlord owns the unit and rents rooms directly, the FHA applies to that landlord. A roommate with no ownership or lease-holder authority isn't the party who owes a reasonable accommodation.
How long does a landlord have to respond to an ESA request?
The FHA sets no fixed clock, but HUD guidance expects a prompt reply. Many housing agencies treat unreasonable delay as a functional denial, which can itself support a discrimination complaint.
