Short answer
A real ESA letter is short, usually under a page. It sits on the clinician's letterhead, shows their license type, number and state, is dated and signed, confirms you have a disability and a disability-related need for your named animal, and supports your request for a reasonable accommodation. It never names your diagnosis.
An ESA letter is short. Most run less than a page. What makes it work isn't length or legal language, it's a handful of specific details that let a landlord see that a licensed professional reviewed your situation and supports your request. If those details are there, the letter does its job under the Fair Housing Act. If they're missing, even a nicely formatted letter can stall your request.
The sample below uses a made-up clinician, client and license number. It shows the structure and wording a real letter follows. It is not a letter you can fill in and use yourself, and the reason why is covered further down.

Re: Request for a reasonable accommodation (emotional support animal)
Resident: Alex Rivera · Animal: Scout, a dog
To whom it may concern,
I am a psychologist licensed in the State of Texas. Alex Rivera is my client, and I am familiar with their history and with the functional limitations caused by their mental health condition.
4Alex has a mental health condition that meets the definition of a disability under the Fair Housing Act. This condition substantially limits one or more of their major life activities.
5In my professional opinion, Alex has a disability-related need for an emotional support animal. Their dog, Scout, provides support that eases one or more symptoms or effects of their disability.
6I support Alex's request for a reasonable accommodation to live with Scout, including an exception to any no-pet policy, pet rent, pet deposit, or breed and weight limit that would otherwise apply.
My license can be confirmed through the Texas Behavioral Health Executive Council using the license number below. Please contact my office with any questions about this letter.
Sincerely,

Notice what's missing. The letter never names a diagnosis, lists medications or describes therapy sessions. Under the 2004 HUD and Justice Department joint statement on reasonable accommodations, a landlord can ask for reliable documentation of a disability-related need, but shouldn't ordinarily ask for your diagnosis or medical records.
Every part of the letter, explained
1. The clinician's letterhead
The top of the letter identifies who wrote it: their name, credentials, practice name and contact details. A landlord should be able to see at a glance that a real person, not a website, is behind the decision. A letter that carries only a company logo and no named professional is one of the most common reasons letters get pushed back.
2. License type, number and state
This is the most important line for anyone checking the letter. The license type (LPC, LCSW, LMFT, psychologist, psychiatrist and so on), the license number and the issuing state let a landlord look the clinician up on the state licensing board's website in a couple of minutes. The clinician should be licensed in the state where you live. Several states now require that by law.
3. The date
Federal law doesn't set an expiration date for ESA letters, but many landlords and property managers want a letter dated within the past 12 months, especially for a new lease. A clearly dated letter avoids that argument. If yours is getting old, a renewal gives you a freshly dated letter.
4. The disability statement
The letter confirms that you have a condition that meets the Fair Housing Act's definition of disability, meaning it substantially limits at least one major life activity such as sleeping, concentrating, working or caring for yourself. It does this without naming the condition. That's deliberate, and it's how a well-written letter protects your privacy.
5. The disability-related need
This sentence connects your condition to the animal: the animal provides support that eases one or more symptoms or effects of the disability. Lawyers call this the nexus. It's the part landlords care about most, because it explains why the accommodation is needed rather than just wanted.
6. The accommodation request
Many letters state what the accommodation covers: living with the animal despite a no-pet policy, and without pet rent, pet deposits or breed and weight limits. Naming the animal (and its species) avoids confusion if you live with more than one pet.
7. Signature
A handwritten or verified electronic signature from the clinician finishes the letter. A typed name with no signature is weaker, and some landlords will ask for a signed copy.
What an ESA letter never needs
- Your diagnosis. The letter confirms a disability, it doesn't name it.
- A registration number or ID card. There's no official ESA registry in the United States, and a certificate or registration bought online doesn't show a disability-related need on its own. See why registration isn't needed.
- A vest or tag. Nice to have for some owners, legally meaningless for housing.
- Your medical records or therapy notes. A landlord can't demand them.
- Training certificates. Emotional support animals don't need task training. That's a service dog requirement, not an ESA one.
Mistakes that get ESA letters questioned
Most rejected letters fail for boring, fixable reasons. The common ones:
- No license number, or a license from another state. If the landlord can't confirm a license in your state, expect questions.
- An old date. A letter from three years ago invites a request for something current.
- Names that don't match. The name on the letter should match the name on your lease or application.
- A template with blanks filled in by you. If it reads like a form anyone could complete, it will be treated like one.
- An animal that isn't named. If you have two cats and the letter says "a cat," you'll likely be asked which one.
If your letter has already been pushed back, our guide on what to do after an ESA letter rejection walks through your options.
Can I write my own ESA letter from a template?
No. A sample like the one above shows you what to expect, but the letter only carries weight because a licensed mental health professional reviewed your situation and is willing to put their name and license behind the statement. A letter you write yourself, or one a friend signs without being a licensed clinician, isn't reliable documentation under fair housing law, and in some states misrepresenting an emotional support animal carries penalties.
What you can do is prepare. Before your assessment, think about what your condition makes harder day to day and what changes when your animal is with you. Those answers are what a clinician needs to make a decision.
How to get a real ESA letter
With ESA Letter US, you complete a short assessment and a mental health professional licensed in your state reviews it. They follow up with you if they need more information, and they decide whether an emotional support animal is right for you. If you're approved, your letter arrives as a PDF with everything shown above: letterhead, license type, number and state, date, the disability-related need and a signature. The ESA housing letter is $99, with $25 for each additional animal.
Frequently asked questions
Does an ESA letter need to name my diagnosis?
No. A well-written ESA letter confirms that you have a disability and a disability-related need for the animal without naming the condition. Landlords can ask for reliable documentation, but not for your diagnosis or medical records.
How long is an ESA letter good for?
Federal law doesn't set an expiration date, but many landlords want a letter dated within the last 12 months, particularly for a new lease. Renewing once a year keeps your letter current.
Can my landlord check that my ESA letter is real?
Yes, within limits. A landlord can confirm the clinician's license on the state licensing board's website using the license number on the letter. They can't ask for your diagnosis, therapy notes or medical history.
Does the letter have to mention my pet by name?
It's not a legal requirement everywhere, but naming the animal and its species is strongly recommended, especially if you live with more than one animal. It avoids follow-up questions about which animal the accommodation covers.
Is a sample ESA letter enough to give my landlord?
No. A sample only shows the format. To support a housing accommodation, the letter has to come from a licensed mental health professional who has reviewed your situation and signs it with their license details.

Find out whether you qualify for an ESA letter
Answer a few questions and a mental health professional licensed in your state reviews your assessment. If you're approved, your Fair Housing Act letter arrives as a PDF, typically within 24 to 48 hours of your evaluation.* $99 one-time, $25 per additional animal, $79 to renew each year. Full refund if you're not approved.
*Arkansas, California, Iowa, Louisiana and Montana require a 30-day client–provider relationship before a letter can be issued, so the letter issues after day 30.
