ESA Letter for Housing: What Landlords Must Accept

An ESA letter for housing is a signed statement from a licensed mental health professional that you have a disability and that your animal helps with it. Under the Fair Housing Act, it is the one document a housing provider is obligated to take seriously, and the only one. Not a registration, not a certificate, not an ID card, ours included. This page covers what a housing-valid letter contains, how to put it in front of your landlord, and where their questions have to stop.

What an ESA letter for housing must contain

HUD's Assistance Animals guidance tells housing providers what counts as reliable documentation, and a letter that clears the bar has a short checklist behind it:

• Written by a licensed professional — a therapist, psychologist, counselor, clinical social worker, psychiatric nurse practitioner, or physician, licensed in your state, with a real treatment or evaluation relationship with you.
• On professional letterhead, with the provider's license type, license number, contact details, signature, and date. The license number is what a leasing office actually verifies.
• States the two facts that matter: you have a mental or emotional condition that qualifies as a disability, and the animal provides support that alleviates at least one symptom of it. No diagnosis needs to appear on paper — privacy is built into the standard.
• Recent. Federal law sets no expiry, but providers customarily expect a letter dated within the past 12 months.

How to submit the request to your landlord

1. Put the request in writing. Email works. Say you are requesting a reasonable accommodation for an assistance animal under the Fair Housing Act, name the animal, and date it. You can make the request before or after moving in, and before or after getting the animal.
2. Attach the letter when they ask for supporting documentation, or attach it up front. That is the document their counsel is looking for.
3. Keep everything in the thread. A dated email chain is worth more three months later than a friendly phone call nobody wrote down.
4. Expect an answer, not silence. HUD treats an ignored accommodation request as a denial, and providers are expected to respond promptly.

What a landlord may ask, and what they may not

Where the disability is not obvious, a provider may ask for reliable documentation of it and of the animal's disability-related need — which is exactly what the letter is. What they generally may not do: demand your diagnosis or medical records, require a demonstration of what the animal does, insist on a specific form of their own, or require the letter to be notarized. And the flip side is worth stating plainly, because it is the honest half of what we sell: a landlord can lawfully decline a registration card or certificate alone. HUD's guidance says documentation bought from the internet, by itself, is not reliable. The letter is the document; the card is the convenience credential you carry with it.

Fees, deposits, and breed rules

• No pet fees or pet deposits. An assistance animal is not a pet under the FHA, so pet rent, pet deposits, and pet fees do not apply to it. You remain liable for actual damage the animal causes.
• Breed and weight limits are not automatic. HUD directs providers to assess the individual animal, not the label on it. A breed list is not the end of the conversation — though a specific dog with a specific bite history is a different matter.
• Buildings with no-pets policies are still covered. The accommodation is an exception to the policy; that is what "reasonable accommodation" means.

The 30-day states

A handful of states add their own requirement: the professional writing the letter must have an established client relationship, commonly at least 30 days, before writing it. California is the best known (AB 468), and Arkansas, Iowa, Louisiana, and Montana have versions of the same idea. If you live in one of these states, a same-day letter mill is not just risky — the letter may not satisfy state law. Our state-by-state guides cover the details, including Texas and Florida.

When a denial is lawful

The FHA is strong, not absolute. A provider can lawfully deny a request when the specific animal poses a direct threat to health or safety, when it would cause substantial physical damage that a lesser condition can't address, when the dwelling is genuinely exempt (owner-occupied buildings with four or fewer units, some single-family homes rented without a broker), or when the documentation itself doesn't hold up. The full picture, including what to do next, is in can a landlord deny an emotional support animal. If you believe a denial crossed the line, you can file a complaint with HUD at no cost.

The short version: get the letter from a real, licensed professional, submit it in writing, and know that fees and breed lists have to bend around it. And if you want the wallet card and the certificate to carry alongside it, register your emotional support animal — we'll keep telling you which document does what.
