An emotional support animal letter from a licensed mental health professional is usually one page. It follows a standard layout. Most genuine letters share the same parts in the same order. There is a clinician header and a short introduction. Then comes a statement of need and a paragraph naming the animal. The letter ends with an accommodation request and a full signature block. Each part helps a housing provider confirm the letter is real.
For healthcare students and professionals, the letter is a useful lesson in clinical documentation. It must protect patient privacy. It must also give a landlord enough to verify the request. Every paragraph reflects that balance. The sections below break the letter down in the order a reader sees it on the page.
What appears at the top of a letter from a mental health professional?
The letter opens with the clinician’s letterhead, the issue date and a plain salutation.
The letterhead shows the clinician’s full name and credentials, such as LMFT, LCSW, LPC or PsyD. It also lists the license number and licensing state. The practice name, address, phone number and email appear here too. The issue date sits just below. The greeting is usually “To Whom It May Concern,” since the patient may not know the property manager’s name.
This header is where most templates fall short. A free template leaves these fields blank or fills them with generic text. A properly prepared emotional support animal (ESA) letter carries real details a landlord can check. A housing provider can confirm them with the state licensing board in a few minutes.
How does the opening paragraph establish the clinician’s role?
It names the writer as a licensed mental health professional who is caring for the patient.
The first sentence identifies the writer and the patient. It confirms the clinician is licensed in a named state, under a stated license number, and in good standing. Some letters also note when treatment began. This links a real, accountable professional to the patient. It happens before the letter makes any request.
Common letter writers include psychologists, psychiatrists and licensed marriage and family therapists (LMFT). Licensed clinical social workers (LCSW), licensed professional counselors (LPC) and licensed mental health counselors (LMHC) write them too. Titles differ by state. What matters is that the license is active and covers the state where the person lives.
Some states shape this paragraph further. California, Arkansas, Iowa, Louisiana and Montana require a clinician relationship of at least 30 days before a housing letter is issued. A California letter written in line with AB 468 usually confirms the relationship has lasted that long. It also lists the date the relationship began next to the issue date.
What does the letter say about the person’s condition?
It confirms a condition that substantially limits a major life activity, usually without naming the diagnosis.
This statement follows the disability standard in the Fair Housing Act. The clinician confirms the patient has a mental or emotional condition. That condition substantially limits one or more major life activities. Examples include sleep, concentration and social functioning. This one sentence carries most of the letter’s legal weight.
A specific diagnosis is not required. Some clinicians describe the condition in general terms. Many leave the diagnosis out completely. No letter should include therapy notes or medical records. Landlords have no right to that detail. Protecting it is part of sound clinical practice and basic patient privacy.
How is the animal named in the recommendation paragraph?
The clinician recommends the animal as part of an ongoing treatment plan and names it.
This paragraph states that the clinician has recommended an emotional support animal to ease the patient’s symptoms. It explains that the animal provides therapeutic support. The letter gives the animal’s name and species. A dog letter may also list the breed. This tells the housing provider exactly which animal the request covers.
A cat letter follows the same pattern, with a few details to note:
- The animal is described as an emotional support cat and named
- One letter can cover more than one cat when the clinician supports the need for each
- Breed, age and training play no part in the assessment
Cats suit many apartment renters, and the structure does not change for them. Whether a patient asks about an ESA letter for cat or dog companionship, the clinical steps match. There is an evaluation and a documented need. Then comes a signed recommendation that names the animal.
What does the closing section of the letter contain?
It holds an accommodation request, an offer to verify and a full signature block.
The second to last paragraph makes the request. It asks the housing provider to allow the animal as a reasonable accommodation under the Fair Housing Act. The request can apply in housing with a no-pets policy. A short line then invites the landlord to contact the clinician directly with any questions.
The letter ends with a sign-off and the clinician’s signature. A signature block follows. It repeats the full name, credentials, license number, licensing state, practice name, phone, email and issue date. The key license details now appear twice on the page. That makes verification easier for the landlord.
How do landlords check whether the letter is genuine?
They can confirm the license and contact the clinician, but they cannot ask about the diagnosis.
Verification is usually simple. A housing provider can look up the license number on the state licensing board’s website. They can confirm the license is active. They can also call or email the clinician to check the letter was issued. Questions about the person’s condition, medical history or treatment are off limits.
This check matters more now. On May 22, 2026, HUD issued an enforcement memo rescinding guidance documents FHEO-2020-01 and FHEO-2013-01. State fair housing agencies now lead enforcement, with HUD in a secondary role. Housing providers weigh each request on its own facts. A complete, verifiable letter carries more weight than before.
RealESALetter.com connects people with clinicians licensed in their state for a live evaluation. Each signed letter is on letterhead. It lists the license number, issue date and contact details a landlord looks for. If a landlord questions the letter, the team works with the landlord directly.
Frequently asked questions
Is a free ESA letter template enough on its own?
No. A template only shows the layout. A licensed clinician must complete and sign the letter after a real evaluation. A registry certificate or ID card is not an ESA letter.
Can a therapist I already see write my ESA letter?
Yes, if they are licensed in your state. They must also agree that an emotional support animal fits your treatment needs. A therapist is not obligated to write one.
How long does an ESA letter stay valid?
Federal law sets no expiry date. Many housing providers expect a letter dated within the past year. Renewing each year keeps it current.
Can one letter cover two or more animals?
Yes. The Fair Housing Act sets no fixed number. The letter must support the need for each animal. The landlord may review each one individually.
What should a tenant do if a landlord rejects a valid letter?
Ask for the reason in writing. Offer the clinician’s contact details for verification. If the refusal stands, contact your state fair housing agency.
TL;DR
A genuine ESA letter follows a clear order: letterhead and date, a clinician introduction, a statement of need, a named animal, an accommodation request and a signature block. RealESALetter issues letters built on that structure. Each one is signed by a clinician licensed in the patient’s state. That puts every detail a housing provider checks right on the page.
