Write the ESA Letter or Decline: HUD's Reliable-Documentation Test

Summary

Writing an emotional support animal letter for a therapy client is defensible when you treat that client and can speak from personal knowledge about a disability-related need for the animal, and it is not defensible otherwise. Federal fair-housing guidance sets a reliability standard rather than a form. Some states add preconditions of their own, including a minimum relationship length in California, so check your state's code before you write.

Should you write it?

Write it if the person is your client, if you have personal knowledge of a disability-related need for the animal, and if your own state's preconditions are met. Decline if any of the three fails. Federal fair-housing guidance names a note from a person's health care professional as one reliable form of documentation confirming a disability or a need for an animal, and conditions it on the professional having personal knowledge of the individual 1.

The third condition is the one that moves. HUD's notice reaches every state, but some states have written statutes on top of it that speak to the clinician rather than the landlord, and those can bar you from providing the document at all. California conditions it on the length of the client-provider relationship 2. Florida turns reliability on personal knowledge and scope of practice, and adds a condition for out-of-state practitioners 3.

Neither is the national rule, and no source here counts how many other states have adopted something like them.

So the lookup comes before the letter. Search your state legislature's code database for the phrase emotional support animal, then search your licensing board's site for the same phrase. A board that has taken a position usually publishes it as a practice advisory rather than a rule.

What HUD's reliability standard asks for

HUD asks for reliable documentation and prescribes no particular document. The notice recommends that documentation from a health care professional contain three things: the patient's name, whether the professional has a professional relationship with that patient involving the provision of health care or disability-related services, and the type of animal 1. The notice recommends those three and requires none of them. The test is reliability, and a treating clinician writing from personal knowledge is what supplies it.

HUD is direct about purchased documentation. In HUD's experience, documentation from the internet is not, by itself, sufficient to reliably establish that an individual has a non-observable disability 1. But distance is not the problem the notice names: it separately contrasts those purchases with licensed professionals who legitimately deliver services remotely, so telehealth is not what HUD is warning about.

The notice also fixes what a housing provider may not demand of you: a specific form, notarized statements, statements under penalty of perjury, or a diagnosis, which housing providers are not entitled to know 1. A landlord form with a signature block for the diagnosis asks for something the guidance says it may not require.

One more federal line matters before you write. Under the Americans with Disabilities Act a service animal is a dog individually trained to do work or perform tasks, and HUD states that emotional support, comfort, well-being and companionship are not a specific work or task for purposes of analysis under the ADA 1. An assistance animal under the Fair Housing Act is the broader category your letter belongs to. Calling it a service animal states something different, under a different statute, that your record probably does not support.

Issued in January 2020, the notice says it remains effective until amended, superseded or rescinded, and it carries the status of guidance and best practice rather than law 1.

Where your state changes the answer

Two states in this set have written the clinician's side of this into statute, and both go further than HUD does. California bars a health care practitioner from providing emotional support dog documentation unless four conditions are met, and names licensing board discipline as the consequence 2. Florida defines when practitioner-supplied information counts as reliable, and adds its own condition for out-of-state practitioners 3. Read your own state before treating either as national.

JurisdictionWhat it adds on top of the federal testWhere it lives
CaliforniaEmotional support dogs only. Four conditions: an active license, with its number, jurisdiction, type and effective date stated in the document; licensure in the jurisdiction; a client-provider relationship of at least 30 days beforehand, with an exception for verified homelessness; a completed clinical evaluation. A notice drawn from Penal Code 365.7 travels with it, and a violation may subject the practitioner to board discipline 2.Health and Safety Code 122318, as amended effective January 1, 2023
FloridaSupporting information is reliable where the practitioner has personal knowledge of the disability and acts within scope of practice. An out-of-state practitioner qualifies only if he or she has provided in-person care to the tenant on at least one occasion. A housing provider may not request the diagnosis or its severity, and an internet registration is not by itself sufficient 3.Florida Statutes 760.27 (2020)
Everywhere elseUnknown from the sources here. Nothing in this set enumerates the other states carrying a precondition of this kind; treat these two as examples.Your state code; your board

California's conditions are cumulative and bind before you write, so a practitioner who met the client two weeks ago has not satisfied the 30-day relationship condition, and the statute's answer is to wait 2. Florida's out-of-state condition catches the telehealth practice: a clinician licensed elsewhere who has never seen the tenant in person does not supply reliable information there 3.

But most readers are in neither state, and there the federal test governs unless the state code says otherwise. Find out which regime you are in before a request arrives.

What goes in the letter, and what stays out

Write to the functional need and stay inside what your treatment record supports. The letter identifies the client, states that you have a professional relationship with that client involving health care or disability-related services, and names the type of animal 1. It does not name the diagnosis. It does not describe the animal's training, temperament or history, because you did not treat the animal, and that assessment is not yours to make.

California adds four drafting items if you practice there: the license number, the jurisdiction, the license type and the effective date, all stated in the document itself, plus the notice its statute requires 2. They are cheap to satisfy and expensive to omit: the statute routes a violation to your board.

Sign it in your own name, on your own letterhead, in your treating capacity. A signature block naming a credential you do not hold in that jurisdiction, or a role you did not occupy with this client, is the part anyone can check.

Get the authorization before anything leaves the office

Nothing goes to a landlord without a signed authorization first. If you are a covered entity, HIPAA bars using or disclosing protected health information without an authorization that is valid under 45 CFR 164.508, and psychotherapy notes carry a separate authorization requirement of their own 4. Whether HIPAA reaches your practice at all is the covered-entity test, worth settling once instead of per request.

The request is a question of who's asking for the therapy record, and here the answer is a housing provider rather than a payer, a court or another treater. That changes the release you need and the amount you send. An authorization naming the housing provider and limited to the accommodation request does not hand over the chart, and a client who delivers the letter keeps the disclosure decision.

Once it arrives on the other side, federal guidance limits what the housing provider may do with it. The joint statement issued by HUD and the Department of Justice states that information supplied in support of a reasonable accommodation must be kept confidential and must not be shared with other persons unless they need the information to decide the request, or unless disclosure is required by law 5. That duty is theirs. It does not stand in for the release on your end, and a disclosure without one is the complaint that returns as the OCR letter.

When declining is the right call

Decline when any one of the three conditions is missing: the person is not your client, you have no personal knowledge of a disability-related need, or your state's precondition is unmet. Decline as well when the question sits outside your competence. For counselors bound by the ACA code, standard C.2.a limits practice to the boundaries of competence based on education, training, supervised experience and credentials 6; other disciplines carry their own version.

A decline reads better when it says what you can do instead. You can confirm that the person is your client and that you have provided health care or disability-related services, one of the three items HUD recommends, without attesting to a need you have not assessed 1. You can offer to complete the evaluation first, or name the date a state relationship condition would be satisfied.

Nothing cited here creates a duty to write one. HUD's notice tells housing providers how to assess a request; the clinician's side is left to the clinician, and to whatever state statute reaches it.

Document the request and your answer in the chart the day it happens. Work like this lands outside the session hour and belongs in your caseload math with every other unbilled task, which is the argument for a standing position rather than an improvised answer each time.

Common questions

The federal test is personal knowledge rather than a session count, so a single visit is not automatically disqualifying. State law can be stricter. California requires a client-provider relationship of at least 30 days before emotional support dog documentation is provided, with an exception for verified homelessness, and Florida's out-of-state condition turns on at least one occasion of in-person care. Check your own code before counting sessions.

No. HUD's notice states that a housing provider may not require a health care professional to disclose a diagnosis, use a specific form, provide notarized statements or write under penalty of perjury, and that housing providers are not entitled to know an individual's diagnosis. Write to the functional need instead. A form insisting on a diagnosis is asking for more than the guidance permits.

HUD's position is that documentation from the internet is not, by itself, sufficient to reliably establish a non-observable disability. That statement is about purchased certificates and registries, not about distance care: HUD separately contrasts them with licensed professionals who legitimately deliver services remotely. A purchased certificate does not substitute for your note, and your note does not need to mention it.

If you are a covered entity, yes. HIPAA bars disclosure of protected health information without a valid authorization, and psychotherapy notes carry their own separate authorization requirement. Have the client sign an authorization naming the housing provider and limited to the accommodation request, keep it in the chart, and send only the letter itself rather than any part of the record.

The federal frame covers assistance animals generally, and the type of animal is one of the three items HUD recommends the documentation state. California's statute on practitioner documentation is written for emotional support dogs only, so another species sits outside it and falls back on the federal test plus any other state rule. Species also bears on the housing provider's own assessment, which is not your decision.

HUD's notice tells housing providers how to assess a request, and nothing cited here creates a duty for a treating clinician to write one. Declining because you lack personal knowledge, because a state precondition is unmet, or because the question falls outside your competence is a professional judgment. Say what you can and cannot attest to, and document the exchange.
