Your landlord has to let your assistance animal live with you. Here's the law, in plain English.
The federal Fair Housing Act (FHA) requires housing providers to make reasonable accommodations for handlers of service animals and emotional support animals — even in buildings with a strict "no pets" policy, and without pet deposits or pet rent. This page explains exactly what your landlord can and cannot ask for, what documentation the law actually requires, the narrow exceptions that apply, and the HUD complaint process if you're denied.
Both service animals and emotional support animals — but not the same way
Under federal housing law, an "assistance animal" is any animal that works, performs tasks, provides assistance, or gives emotional support that alleviates a disability. That definition is broader than the ADA's, which is why ESAs have housing protection that they do not have in restaurants or stores.
Service Dogs & Psychiatric Service Dogs
Protected in housing and in places of public accommodation (stores, restaurants, hotels, airports). In housing, your landlord treats them the same as any assistance animal — no pet fees, no breed or weight limits, no "no pets" enforcement.
- No letter from a clinician required for housing
- Landlord may ask only whether the animal is needed for a disability and what work or task it performs (if non-obvious)
- Protected coast-to-coast, every covered rental
Emotional Support Animals
Protected under the FHA for housing — not under the ADA for businesses or airlines. For housing accommodation specifically, you will typically need a letter from a licensed mental-health or medical professional who has a therapeutic relationship with you, confirming you have a disability and the animal alleviates a symptom.
- No species limit — dogs, cats, rabbits, birds, and others have all been approved
- No training requirement — ESAs are not task-trained
- Registration certificates alone are not sufficient documentation
What a landlord can and cannot ask
HUD's 2020 guidance (FHEO-2020-01) is the plain-language rulebook on this. If a landlord asks something in the red column, they're outside the law.
CAN ask
Permitted questions & documentation- "Is the animal required because of a disability?" A simple yes/no. They are not entitled to know what your disability is.
- "What work or task has the animal been trained to perform?" Only if the disability is not obvious. For ESAs this is replaced with "what disability-related need does this animal alleviate?" — you don't have to say more than that.
- A reliable letter from a licensed professional For ESAs (and sometimes for non-obvious SD disabilities), a letter from a clinician who has a therapeutic relationship with you, confirming the disability and the animal's role. We have a full guide to legitimate ESA letters.
- Current vaccinations Landlords may require the animal meet the same vaccination standards any other animal in the building would have to meet (typically rabies). They cannot invent new health requirements just for your animal.
- A reasonable request for the animal to be under control Leashed in common areas, quiet enough not to disturb neighbors, house-trained. The animal's behavior — not its existence — can be regulated.
CANNOT ask
Illegal demands under the FHA- Medical records, diagnosis, or your specific condition The landlord verifies you have a disability-related need — never what the disability is.
- A pet deposit, pet rent, pet fee, or any "animal fee" Assistance animals are not pets under the FHA. Any fee charged to pet-owners cannot be charged to you for an assistance animal. You remain liable for actual damage caused by the animal, same as for any damage you cause.
- Breed or weight restrictions "No pit bulls" or "30 lb limit" rules do not apply to assistance animals. The individual animal's behavior is what matters, not its breed.
- Species restrictions (with narrow exceptions) Dogs, cats, rabbits, birds, reptiles — all have been approved. A landlord can only refuse a species if it poses a direct threat or fundamentally alters the nature of the housing (e.g., a miniature horse in a 400-sq-ft studio).
- Specific registration, certification, or training documents There is no federal registration required. A USSAR registration can make your request cleaner to administer, but a landlord cannot require that you have one.
- Proof the animal is a "certified" service animal No federal certification exists. Anyone telling you otherwise — including your landlord — is mistaken.
- A delay beyond what is reasonable Accommodation requests must be handled promptly. Indefinite "we're reviewing it" is a denial.
The documentation gap — and what our registration actually does
We want to be direct about this because a lot of sites are not: a registration certificate alone is not the documentation the FHA requires for an ESA housing request.
For a service dog or psychiatric service dog, the FHA and HUD guidance do not require any letter at all. The landlord can ask the two standard ADA questions (is this needed because of a disability; what work or task is it trained to perform) — and that's it. Having a tangible ID, tags, and a verifiable registration makes these conversations faster and cleaner, but they're not a legal gate. That's what our SD/PSD packages give you.
For an emotional support animal, the landlord is generally entitled to request a letter from a clinician who has a therapeutic relationship with you and who, within the scope of their licensure, has formed a clinical opinion that you have a disability and the animal alleviates a symptom. That letter is the actual legal document.
What our ESA registration is, and isn't
Our ESA registration is a tangible identification system — a registration number, ID cards, tags, and a public verification page — that most housing providers find easier to administer than a stand-alone clinician letter. What it is not, and cannot be, is a substitute for a real clinical letter when the landlord requests one. If you don't have a letter, we point you toward vetted telehealth clinicians in our ESA Letter Guide. We do not sell letters. We have never sold letters.
About "fake letter" websites
If you see a site offering a "15-minute ESA letter" with no actual clinical evaluation, stay away. HUD explicitly rejects these letters as unreliable documentation, several state legislatures have criminalized them, and more importantly — they don't protect you. If your landlord pushes back, your "letter" will not hold up. See our fake-letter red flags guide.
Who counts as a "licensed professional" for an ESA letter?
HUD's 2020 guidance accepts letters from licensed physicians, psychiatrists, psychologists, licensed clinical social workers, licensed marriage and family therapists, licensed mental-health counselors, and nurse practitioners operating within their scope of practice. The key is licensure, an established therapeutic relationship, and a clinical opinion — not a one-off, 5-minute online intake.
What a good ESA letter contains
HUD's guidance says the landlord is entitled to information that is "reasonable to determine" whether the disability-related need is real. A letter that does the job typically contains: clinician's letterhead with license number and jurisdiction; statement that you are their patient; statement that you have a disability as defined by the FHA (not the specific diagnosis); statement that the animal provides support that alleviates one or more symptoms; and the clinician's signature and date. One page. No more information than HUD allows.
When the FHA does not apply — and when a landlord can refuse
The law has real teeth, but it also has limited carve-outs. Knowing these upfront prevents you from being caught off-guard and helps you recognize when a denial is actually lawful.
The "Mrs. Murphy" exemption — small owner-occupied buildings
Owner-occupied buildings with four or fewer units, where the owner lives in one of the units, are exempt from the FHA's disability-accommodation rules. A landlord living on-site in a duplex, triplex, or fourplex can legally refuse you. Apartment buildings, condo associations, single-family rentals managed by an owner not living in the home, and most large landlords are not exempt.
Single-family homes rented without a broker
A single-family home sold or rented by the owner without using a real-estate agent or broker — and where the owner does not own more than three such homes — is partially exempt. This is a narrow carve-out; most rentals through Zillow, Apartments.com, or a property manager do not qualify.
Direct threat, based on objective evidence
A landlord can refuse a specific animal if that individual animal has a history of aggressive behavior toward people — documented bites, attacks, or formal complaints from neighbors. The refusal has to be based on the animal itself, not on its breed. A blanket "no pit bulls" rule still violates the FHA; a refusal of one specific pit bull with three documented bite incidents does not.
Undue financial or administrative burden
Very rare, but it exists — primarily for small operators. The landlord has to show the accommodation would impose significant financial burden or would fundamentally alter the nature of the housing. "It'll be inconvenient" or "other tenants might complain" are not sufficient.
The animal causes actual damage
You are liable for actual damage the animal causes to the unit, same as you would be for any damage. A landlord who keeps your security deposit for a carpet the animal destroyed is following the law. What they cannot do is charge a deposit in advance specifically because you have an assistance animal.
The animal is not under the handler's control or is not housebroken
The accommodation is for the handler-animal team, not for unsupervised animals. If the animal is repeatedly loose in common areas, aggressive, or not house-trained, the landlord can require corrective action and — after documented failures to remedy — can terminate the accommodation.
Filing a HUD complaint, step by step
The U.S. Department of Housing and Urban Development enforces the Fair Housing Act. Filing with HUD is free, you do not need a lawyer, and the process is designed to work for individuals.
Document the denial
Get the landlord's refusal in writing. If they refused verbally, send a follow-up email summarizing the conversation and asking them to confirm the denial in writing. Save texts, emails, voicemails, notes with dates. Without documentation, the complaint is harder.
File within 1 year
HUD accepts complaints up to one year after the discriminatory act. File online at hud.gov, by phone at 1-800-669-9777, or by mail to the regional HUD office. Filing is free.
HUD investigates
HUD aims to resolve cases within 100 days. They'll contact the landlord, gather records, and often propose conciliation — the landlord agrees to accommodate and sometimes pay damages, without admitting wrongdoing.
Enforcement if needed
If conciliation fails and HUD finds reasonable cause, the case moves to a HUD administrative law judge or the DOJ for a civil action. Remedies include moving you in, compensatory damages, and civil penalties against the landlord.
Reasonable-accommodation request letter
You do not have to use formal legal language to make a reasonable-accommodation request — but landlords take written requests more seriously than verbal ones. Use the template below as a starting point. Swap the highlighted fields for your own details.
[Your current address, unit #]
[City, State, ZIP]
[Landlord address]
Dear [Landlord name],
I am a tenant at [building address / unit], and I am writing to request a reasonable accommodation to the property's pet policy. I have a disability as defined by the Fair Housing Act, and an assistance animal is necessary to provide me with an equal opportunity to use and enjoy my dwelling.
Specifically, I am requesting that my assistance animal, [animal name], a [species / breed], be permitted to live with me in my unit. This is a request under 42 U.S.C. §3604(f)(3)(B) of the Fair Housing Act and HUD's 2020 guidance on assistance animals (FHEO-2020-01).
(For ESAs, include:) Enclosed is a letter from [clinician name, credentials, license number], who has a therapeutic relationship with me, confirming my disability-related need for the animal.
(For SD/PSDs, include:) The animal has been trained to perform the following task(s) that assist with my disability: [one-line description of task]. I can also provide a registration record at [verification URL].
Under the Fair Housing Act, assistance animals are not pets, and any pet-related fees, deposits, breed restrictions, or weight limits do not apply. I remain fully responsible for any actual damage the animal may cause and for keeping the animal under control at all times.
Please confirm in writing within [10–14] days whether this accommodation will be granted. If you have any questions about the documentation or need additional information allowed under HUD guidance, I am happy to provide it.
Thank you for your prompt attention.
Sincerely,
[Your signature]
