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

The FHA's reliable-documentation standard, spelled out in HUD's 2020 guidance until HUD withdrew it in 2025, and still the standard leasing offices and their attorneys apply, 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. Courts treat 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. What they cannot do is refuse a genuine letter outright: the reliable-documentation standard is the ceiling of what they may demand, not a menu of reasons to say no. 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 2020 guidance said documentation bought from the internet, by itself, is not reliable, and its 2025 withdrawal gave certificates no new weight. 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. Courts applying the FHA require assessment of 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 four 30-day states

Four states add their own timing rule: the professional writing the letter must have an established client relationship of at least 30 days before writing it. California is the best known (AB 468, which covers emotional support dog documentation), Arkansas takes the same dogs-only approach, and Louisiana and Montana apply the rule to any species. Iowa is often miscounted as a fifth: it imposes no waiting period, but the provider's written finding must certify whether a 30-day relationship exists, a disclosure rather than a wait, and one that tells your landlord exactly how new the relationship is. If you live in one of the four 30-day 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, start with your state fair-housing agency (filing costs nothing, and many enforce state laws broader than the FHA) and know that the statute preserves your right to sue in state or federal court within two years. You can still file with HUD at no cost, though since its May 2026 enforcement memo HUD's fair-housing office no longer pursues complaints over untrained emotional support animals.

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.
