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 1Ref 1U.S. Department of Housing and Urban Development, Office of Fair Housing and Equal Opportunity (2020).FHEO Notice: FHEO-2020-01 — Assessing a Person's Request to Have an Animal as a Reasonable Accommodation Under the Fair Housing Act.HUD's reliability standard for documentation from a treating health care professional: the note as one reliable form conditioned on personal knowledge, the three recommended contents, the statement that internet documentation is not by itself sufficient for a non-observable disability alongside the contrast with legitimate remote practice, the bar on requiring a specific form, notarization, statements under penalty of perjury or a diagnosis, the ADA service-animal versus FHA assistance-animal split, and the notice's own 2020 issuance and guidance status..
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 2Ref 2California State Legislature (2022).California Health and Safety Code Section 122318.California only: the four preconditions on a health care practitioner providing emotional support dog documentation, including the license details stated in the document, the client-provider relationship of at least 30 days with the verified-homelessness exception, and the completed clinical evaluation, plus the Penal Code 365.7 notice and the licensing-board discipline exposure, as amended effective January 1, 2023.. Florida turns reliability on personal knowledge and scope of practice, and adds a condition for out-of-state practitioners 3Ref 3Florida Legislature (2020).Florida Statutes Section 760.27 — Prohibited discrimination in housing provided to persons with a disability or disability-related need for an emotional support animal.Florida only: that practitioner-supplied supporting information is reliable where the practitioner has personal knowledge of the disability and acts within scope of practice, the in-person-care condition on an out-of-state practitioner, the bar on a housing provider requesting diagnosis or severity, and that an internet registration is not by itself sufficient..
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 1Ref 1U.S. Department of Housing and Urban Development, Office of Fair Housing and Equal Opportunity (2020).FHEO Notice: FHEO-2020-01 — Assessing a Person's Request to Have an Animal as a Reasonable Accommodation Under the Fair Housing Act.HUD's reliability standard for documentation from a treating health care professional: the note as one reliable form conditioned on personal knowledge, the three recommended contents, the statement that internet documentation is not by itself sufficient for a non-observable disability alongside the contrast with legitimate remote practice, the bar on requiring a specific form, notarization, statements under penalty of perjury or a diagnosis, the ADA service-animal versus FHA assistance-animal split, and the notice's own 2020 issuance and guidance status.. 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 1Ref 1U.S. Department of Housing and Urban Development, Office of Fair Housing and Equal Opportunity (2020).FHEO Notice: FHEO-2020-01 — Assessing a Person's Request to Have an Animal as a Reasonable Accommodation Under the Fair Housing Act.HUD's reliability standard for documentation from a treating health care professional: the note as one reliable form conditioned on personal knowledge, the three recommended contents, the statement that internet documentation is not by itself sufficient for a non-observable disability alongside the contrast with legitimate remote practice, the bar on requiring a specific form, notarization, statements under penalty of perjury or a diagnosis, the ADA service-animal versus FHA assistance-animal split, and the notice's own 2020 issuance and guidance status.. 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 1Ref 1U.S. Department of Housing and Urban Development, Office of Fair Housing and Equal Opportunity (2020).FHEO Notice: FHEO-2020-01 — Assessing a Person's Request to Have an Animal as a Reasonable Accommodation Under the Fair Housing Act.HUD's reliability standard for documentation from a treating health care professional: the note as one reliable form conditioned on personal knowledge, the three recommended contents, the statement that internet documentation is not by itself sufficient for a non-observable disability alongside the contrast with legitimate remote practice, the bar on requiring a specific form, notarization, statements under penalty of perjury or a diagnosis, the ADA service-animal versus FHA assistance-animal split, and the notice's own 2020 issuance and guidance status.. 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 1Ref 1U.S. Department of Housing and Urban Development, Office of Fair Housing and Equal Opportunity (2020).FHEO Notice: FHEO-2020-01 — Assessing a Person's Request to Have an Animal as a Reasonable Accommodation Under the Fair Housing Act.HUD's reliability standard for documentation from a treating health care professional: the note as one reliable form conditioned on personal knowledge, the three recommended contents, the statement that internet documentation is not by itself sufficient for a non-observable disability alongside the contrast with legitimate remote practice, the bar on requiring a specific form, notarization, statements under penalty of perjury or a diagnosis, the ADA service-animal versus FHA assistance-animal split, and the notice's own 2020 issuance and guidance status.. 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 1Ref 1U.S. Department of Housing and Urban Development, Office of Fair Housing and Equal Opportunity (2020).FHEO Notice: FHEO-2020-01 — Assessing a Person's Request to Have an Animal as a Reasonable Accommodation Under the Fair Housing Act.HUD's reliability standard for documentation from a treating health care professional: the note as one reliable form conditioned on personal knowledge, the three recommended contents, the statement that internet documentation is not by itself sufficient for a non-observable disability alongside the contrast with legitimate remote practice, the bar on requiring a specific form, notarization, statements under penalty of perjury or a diagnosis, the ADA service-animal versus FHA assistance-animal split, and the notice's own 2020 issuance and guidance status..
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 2Ref 2California State Legislature (2022).California Health and Safety Code Section 122318.California only: the four preconditions on a health care practitioner providing emotional support dog documentation, including the license details stated in the document, the client-provider relationship of at least 30 days with the verified-homelessness exception, and the completed clinical evaluation, plus the Penal Code 365.7 notice and the licensing-board discipline exposure, as amended effective January 1, 2023.. Florida defines when practitioner-supplied information counts as reliable, and adds its own condition for out-of-state practitioners 3Ref 3Florida Legislature (2020).Florida Statutes Section 760.27 — Prohibited discrimination in housing provided to persons with a disability or disability-related need for an emotional support animal.Florida only: that practitioner-supplied supporting information is reliable where the practitioner has personal knowledge of the disability and acts within scope of practice, the in-person-care condition on an out-of-state practitioner, the bar on a housing provider requesting diagnosis or severity, and that an internet registration is not by itself sufficient.. Read your own state before treating either as national.
| Jurisdiction | What it adds on top of the federal test | Where it lives |
|---|---|---|
| California | Emotional 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 2Ref 2California State Legislature (2022).California Health and Safety Code Section 122318.California only: the four preconditions on a health care practitioner providing emotional support dog documentation, including the license details stated in the document, the client-provider relationship of at least 30 days with the verified-homelessness exception, and the completed clinical evaluation, plus the Penal Code 365.7 notice and the licensing-board discipline exposure, as amended effective January 1, 2023.. | Health and Safety Code 122318, as amended effective January 1, 2023 |
| Florida | Supporting 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 3Ref 3Florida Legislature (2020).Florida Statutes Section 760.27 — Prohibited discrimination in housing provided to persons with a disability or disability-related need for an emotional support animal.Florida only: that practitioner-supplied supporting information is reliable where the practitioner has personal knowledge of the disability and acts within scope of practice, the in-person-care condition on an out-of-state practitioner, the bar on a housing provider requesting diagnosis or severity, and that an internet registration is not by itself sufficient.. | Florida Statutes 760.27 (2020) |
| Everywhere else | Unknown 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 2Ref 2California State Legislature (2022).California Health and Safety Code Section 122318.California only: the four preconditions on a health care practitioner providing emotional support dog documentation, including the license details stated in the document, the client-provider relationship of at least 30 days with the verified-homelessness exception, and the completed clinical evaluation, plus the Penal Code 365.7 notice and the licensing-board discipline exposure, as amended effective January 1, 2023.. 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 3Ref 3Florida Legislature (2020).Florida Statutes Section 760.27 — Prohibited discrimination in housing provided to persons with a disability or disability-related need for an emotional support animal.Florida only: that practitioner-supplied supporting information is reliable where the practitioner has personal knowledge of the disability and acts within scope of practice, the in-person-care condition on an out-of-state practitioner, the bar on a housing provider requesting diagnosis or severity, and that an internet registration is not by itself sufficient..
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 1Ref 1U.S. Department of Housing and Urban Development, Office of Fair Housing and Equal Opportunity (2020).FHEO Notice: FHEO-2020-01 — Assessing a Person's Request to Have an Animal as a Reasonable Accommodation Under the Fair Housing Act.HUD's reliability standard for documentation from a treating health care professional: the note as one reliable form conditioned on personal knowledge, the three recommended contents, the statement that internet documentation is not by itself sufficient for a non-observable disability alongside the contrast with legitimate remote practice, the bar on requiring a specific form, notarization, statements under penalty of perjury or a diagnosis, the ADA service-animal versus FHA assistance-animal split, and the notice's own 2020 issuance and guidance status.. 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 2Ref 2California State Legislature (2022).California Health and Safety Code Section 122318.California only: the four preconditions on a health care practitioner providing emotional support dog documentation, including the license details stated in the document, the client-provider relationship of at least 30 days with the verified-homelessness exception, and the completed clinical evaluation, plus the Penal Code 365.7 notice and the licensing-board discipline exposure, as amended effective January 1, 2023.. 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.
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 6Ref 6American Counseling Association (2014).2014 ACA Code of Ethics.The competence half of the decline decision for ACA-governed counselors: standard C.2.a limits practice to the boundaries of competence based on education, training, supervised experience and credentials. It is a professional code rather than law and binds only counselors under it.; 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 1Ref 1U.S. Department of Housing and Urban Development, Office of Fair Housing and Equal Opportunity (2020).FHEO Notice: FHEO-2020-01 — Assessing a Person's Request to Have an Animal as a Reasonable Accommodation Under the Fair Housing Act.HUD's reliability standard for documentation from a treating health care professional: the note as one reliable form conditioned on personal knowledge, the three recommended contents, the statement that internet documentation is not by itself sufficient for a non-observable disability alongside the contrast with legitimate remote practice, the bar on requiring a specific form, notarization, statements under penalty of perjury or a diagnosis, the ADA service-animal versus FHA assistance-animal split, and the notice's own 2020 issuance and guidance status.. 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.
