Providers
Who Can Write an ESA Letter in Texas
A licensed health care professional, practising in the state where you are. In Texas that covers more license types than most people expect — and excludes several businesses that sell letters anyway.
The standard for the writer
HUD’s guidance frames this in terms of documentation from a licensed health care professional who has personal knowledge of the individual. Two words carry the weight. Licensed means a live credential a housing provider can check with a state board. Personal knowledge means the professional has actually assessed you, rather than processed a form you filled in alone.
Nothing in the Fair Housing Act restricts this to psychiatrists, and nothing requires a years-long treatment history. What it does require is a real professional exercising real judgment about a real person.
Texas licenses that qualify
These are the credentials that most commonly appear on Texas assistance animal documentation, with the board that issues each. All are verifiable by the public.
| Provider | Common abbreviation | Texas licensing board |
|---|---|---|
| Licensed Clinical Social Worker | LCSW | Behavioral Health Executive Council |
| Licensed Professional Counselor | LPC, LPC-S | Behavioral Health Executive Council |
| Licensed Psychologist | PhD, PsyD | Behavioral Health Executive Council |
| Licensed Marriage and Family Therapist | LMFT | Behavioral Health Executive Council |
| Psychiatrist or physician | MD, DO | Texas Medical Board |
| Physician assistant | PA | Texas Medical Board |
| Advanced practice registered nurse | APRN, PMHNP | Texas Board of Nursing |
Our letters are written by Calvin Cano, LCSW, whose credential falls in the first row and is verifiable through the Behavioral Health Executive Council.
Out-of-state providers
This is where a lot of purchased letters quietly fail. A therapist licensed in another state cannot generally evaluate you while you are sitting in Texas, because licensure is state by state and what governs the appointment is your physical location, not theirs.
A provider licensed in thirty states including Texas is fine. A provider licensed only in California who evaluates a Houston tenant is not, and a landlord’s attorney who checks the license number will find out quickly. If you already have a therapist in another state whom you see regularly, they may still be able to write for you — that is a question for them and their own board, not for us.
Our telehealth consent page covers the location rule in detail, including what it means if you travel or live near a border.
Who cannot write one
- A registry, certification body or “ESA authority.” None of these exist in law. They cannot issue documentation because they are not health care providers.
- A veterinarian. Your vet knows the animal, not your disability. A vet letter about temperament can be a useful supporting document, but it is not the documentation the Fair Housing Act contemplates.
- A trainer. Training is irrelevant to an emotional support animal, and a trainer has no standing to speak to your condition.
- A friend, employer, pastor or family member, however well they know you.
- You. A self-written statement is not third-party documentation.
- An unlicensed “counsellor” or coach. Life coaches, wellness coaches and unlicensed therapists are not licensed health care professionals, whatever their website says.
Why the relationship matters
HUD’s 2020 notice is unusually blunt about purchased documentation. It states that in HUD’s experience, documentation from a website that sells letters to anyone who fills in a questionnaire is not, by itself, sufficient to reliably establish a non-observable disability or a disability-related need for an animal.
That sentence is the reason a live evaluation exists at all. The length of the appointment is not the point — a brief clinical screen is still a clinical screen. The point is that a licensed professional formed a judgment about you personally, and can say so on their own letterhead under their own license number.
Verify a license in two minutes
- Ask for the provider’s full name, license type and license number. Any legitimate provider answers without hesitation.
- For counsellors, social workers, psychologists and marriage and family therapists, search the Texas Behavioral Health Executive Council license lookup.
- For physicians and physician assistants, search the Texas Medical Board. For nurse practitioners, the Texas Board of Nursing.
- Check three things: the license is active, it is issued in Texas, and there is no disciplinary history that concerns you.
If a service will not give you a name and a number before you pay, you already have your answer.
Ask your own provider first
If you are already seeing a licensed provider in Texas, ask them before you pay anybody. Their letter is usually free to you, and it is stronger than ours, because an established treatment relationship is exactly what HUD’s guidance is pointing at. We would rather tell you that than take your money.
Some providers decline, occasionally as a matter of practice policy. If yours does, that is when a referral service is worth using — and the questions on this page are the ones to ask before you choose one.
