Valid letters
What a valid ESA letter contains
Seven elements, plus the things a housing provider isn’t entitled to ask for. If a letter you bought is missing the first two, it’s paper, not documentation.
1. A therapist licensed in Texas
The letter must come from a licensed health care professional, and for practical purposes that means someone licensed to practice in Texas: a psychologist, licensed professional counselor, licensed clinical social worker, licensed marriage and family therapist, psychiatrist, physician, physician assistant or nurse practitioner.
Behavioral health licenses in Texas are issued through the Texas Behavioral Health Executive Council, and its public verification tool will tell you in seconds whether a license is real and in good standing. If a provider won’t give you a license number, that answers your question.
2. Evidence of a real clinical relationship
HUD’s guidance is unusually direct about this. It states that in HUD’s experience, documentation from a website that sells letters to anyone who fills in a questionnaire isn’t, by itself, sufficient to reliably establish that someone has a non-obvious disability or a disability-related need for an animal.
In practice a landlord or their attorney is looking for a letter that reads as though a professional actually met you. That means it refers to an evaluation or an ongoing treatment relationship, and it sounds like a therapist wrote it rather than a form generator.
3. A disability statement, not a diagnosis
The letter should confirm that you’ve a physical or mental impairment that substantially limits one or more major life activities. That’s the legal standard the accommodation rests on.
It shouldn’t name your diagnosis. A housing provider is entitled to know that a disability-related need exists; it isn’t entitled to your diagnostic label, your medication list or your records.
4. The connection between the animal and the condition
This is the element most purchased letters get wrong, and it’s the one that decides close cases. The letter has to link the animal to the effects of the condition, not simply assert that you like the animal or find it comforting.
A weak letter says the patient benefits from emotional support. A strong letter explains that the animal’s presence alleviates specific identified symptoms, in this therapist’s professional opinion, and that keeping the animal in the home is necessary for the patient to have equal use and enjoyment of the dwelling.
5. The animal, identified
Species, and usually the name. Under the Fair Housing Act assistance animals aren’t limited to dogs and no training is required, but if you’re asking to keep an animal that isn’t commonly kept in households, the burden on you is substantially heavier and the letter needs to address why that particular animal is necessary.
6. Letterhead, signature and license number
Professional letterhead with the practice name, address and phone number. A signature. The license type, number and state. A landlord who wants to confirm the letter is genuine should be able to do so from the letter itself.
7. A recent date
No federal rule sets an expiry, but Texas landlords commonly ask for documentation dated within the past twelve months, and many ask again at renewal. A letter from four years ago invites a fight you do not need.
What to leave out
- Your diagnosis, your medication list, your records or your session notes.
- Any claim of public access rights. An ESA has none, and a letter that claims otherwise damages your credibility and can expose you to the Texas misrepresentation offence.
- Any claim about air travel. Airlines haven’t been required to accommodate ESAs since early 2021.
- The words “registered,” “certified” or “prescription.” There’s no registry and no certification, and a letter that uses that language reads as a purchase.
What a landlord can’t demand
| A housing provider may | A housing provider may not |
|---|---|
| Ask for documentation of a disability-related need when the disability isn’t obvious | Ask for your diagnosis or your medical records |
| Ask you to put the request in writing, if that’s its normal practice | Charge a pet fee, pet deposit or pet rent for an approved assistance animal |
| Ask follow-up questions about the animal’s role, especially for an unusual species | Require registration, certification, an ID card, a vest or professional training |
| Deny the request if the specific animal is a direct threat or would cause substantial damage | Apply breed, size or weight restrictions to an assistance animal |
| Hold you responsible for actual damage the animal causes | Delay indefinitely, or ignore the request, which can itself be a violation |
Mill vs. therapist
The tell is almost never the price. It’s whether a human being with a verifiable license actually spoke with you before anyone wrote anything down. Speed isn’t the tell — once a therapist has evaluated you, generating the letter takes seconds. The tell is a form you fill in alone, with no live appointment anywhere in the process, whatever the checkout page says.
Before you pay, ask two questions: who is the licensed therapist, and what’s their Texas license number. Then check it. Any legitimate provider will answer both without hesitation, and ours are published on this site.
