May 22, 2026: HUD's Office of Fair Housing and Equal Opportunity (FHEO) issued an enforcement memorandum permanently rescinding its 2020 guidance on assistance animals and changing how the agency will handle animal-related reasonable-accommodation complaints under the Fair Housing Act.

The important part for clinicians is what did not change.

The Fair Housing Act itself was not amended by this memorandum. HUD changed its enforcement posture, not the statutory text. State and local laws also remain in effect. California clinicians, for example, still have to comply with AB 468's requirements when providing documentation related to an emotional support dog.

That distinction matters if you write ESA letters.

You do not need to stop writing letters. You do need to understand what your letter can establish, what it cannot establish, and which rules apply to the patient in front of you.

What this update covers

• What HUD changed on May 22, 2026, and why the Fair Housing Act still matters
• What the rescission changes for clinicians writing ESA documentation
• What state law still requires, using California as the worked example
• How to document an ESA assessment defensibly while the federal picture shifts

What changed on May 22, 2026?

On May 22, 2026, HUD instructed FHEO to use a narrower enforcement standard for animal-related reasonable-accommodation complaints under the Fair Housing Act.

Under the new memorandum, FHEO says it will find reasonable cause and recommend charges only when the animal has been individually trained to perform work or tasks directly related to the complainant's disability. HUD is therefore using the training component of the ADA service-animal definition when assessing these FHA complaints.

That is a major change from HUD's 2020 guidance.

The 2020 FHEO notice expressly recognized both trained and untrained assistance animals, including animals that provided therapeutic emotional support to people with disabilities. It also gave housing providers a detailed framework for evaluating accommodation requests and disability-related documentation.

The 2020 guidance is no longer active HUD guidance.

The timeline matters

There are two dates worth keeping separate:

Sources: HUD enforcement guidance, May 22, 2026 · HUD withdrawal notice, 91 FR 17291 (April 6, 2026)

The May 22 memorandum itself says the 2020 notice was being permanently rescinded and establishes the new enforcement approach going forward.

Bottom line: May 22 is the date clinicians should know for the new enforcement standard, but the underlying HUD guidance had already been withdrawn in September 2025.

Did HUD change the Fair Housing Act?

No. The May 22 memorandum did not amend the Fair Housing Act.

The FHA remains federal law, including its prohibition against housing discrimination based on disability and its reasonable-accommodation provision. The implementing regulation still gives waiving a no-pets rule for an assistance animal as its example of an accommodation a housing provider may have to make.

What changed is how HUD says its enforcement office will handle complaints.

That distinction is easy to lose in headlines.

A federal agency can change its enforcement priorities without Congress changing the underlying statute. The May 22 memo is an agency enforcement document, not legislation amending the FHA. The memo also states that it does not eliminate the ability of private parties to seek redress through litigation.

So clinicians should avoid two opposite conclusions:

• "Nothing changed." Something important did change: HUD's enforcement posture is narrower.
• "ESAs are no longer protected under federal housing law." That is broader than what the memorandum establishes.

The legal landscape is therefore more complicated than simply saying that ESAs are now legal or illegal under the FHA.

What does HUD's new enforcement standard mean for an ESA letter?

A clinician's letter is still clinical documentation. It is not a guarantee that HUD, a landlord, a court, or another agency will reach a particular legal conclusion.

The practical change is that clinicians should be especially careful about describing what the letter establishes.

Under the new HUD enforcement posture, an accommodation complaint involving an untrained emotional support animal is not the type of case in which FHEO says it will find reasonable cause and recommend charges. By contrast, HUD says complaints involving an animal individually trained to perform disability-related work or tasks can meet its new enforcement standard.

That does not mean your clinical assessment is irrelevant.

It means your letter should not overstate the federal legal effect of your clinical opinion.

A clinician can document:

• The patient's relevant clinical condition
• Functional limitations
• The patient's reported relationship with the animal
• Your clinical assessment
• Your professional opinion about the patient's disability-related need
• The accommodation being requested

A clinician should not automatically certify:

• That the animal is a service animal
• That the animal is trained to perform disability-related tasks
• That the patient has unrestricted public-access rights
• That a housing provider is legally required to approve the request
• That an ESA letter overrides state law

Those are different questions.

Should clinicians stop writing ESA letters?

No. The HUD memo does not instruct clinicians to stop providing clinical documentation.

Instead, clinicians should separate clinical judgment from legal outcome.

If you have enough information to form a professional opinion that an animal provides disability-related support for a patient, you can document that opinion within your scope of practice and applicable law.

Your responsibility is to make the documentation accurate and clinically defensible.

The housing provider, patient, attorney, court, or government agency may then have to determine what legal consequence follows.

This distinction is especially important because state and local laws can provide requirements or protections that differ from HUD's federal enforcement posture.

The memorandum is enforcement guidance for FHEO. It does not address complaints under Section 504 or the ADA, and it states that nothing in it affects a party's right to seek redress through a private action in court. It does not speak to state law at all, which is why state requirements keep running on their own track.

What should clinicians change in their ESA assessment?

The biggest practical change is not a new sentence you need to put in every letter.

It is a stronger assessment process.

An ESA request should not begin with a template. It should begin with the patient.

A useful assessment establishes:

• Clinical condition: What condition or symptoms are relevant?
• Functional impact: How does the condition affect the patient's functioning?
• Animal relationship: What does the animal actually do for the patient?
• Clinical rationale: What is the connection between the patient's condition and the animal?
• Accommodation requested: What is the patient actually asking the housing provider to accommodate?
• Professional basis: Do you have enough information and an appropriate relationship to provide the documentation?

A structured assessment gives you a documented picture of symptoms, functioning, supports and relevant clinical factors before you make a documentation decision. If the question is whether you are the right clinician to write it at all, start with who can write an ESA letter. Our guide to ESA letters for clinicians walks through that assessment and the letter structure in full, including what to leave out.

Do not reduce the assessment to a diagnosis

A diagnosis alone does not explain why a particular accommodation is clinically appropriate.

Two patients with the same diagnosis may have very different functional limitations and very different relationships with an animal.

Instead of:

"Patient has anxiety and needs an ESA."

your documentation should establish the clinical reasoning behind the conclusion.

For example:

"The patient reports that the presence and care of the animal helps reduce distress associated with [relevant symptoms] and supports [relevant area of functioning]. Based on the clinical information available to me, I consider the animal's presence relevant to the patient's disability-related needs."

The exact language should reflect your actual assessment. Do not copy this sentence into a chart without establishing that it is true for the patient.

What should an ESA letter say after HUD's policy change?

The basic clinical structure does not need to become a legal brief.

A focused letter can identify:

• Your professional identity and credentials
• Your relationship with the patient
• The relevant clinical condition or disability-related information
• The relevant functional impact
• The animal's relationship to that impact
• Your professional opinion
• The accommodation being requested
• Your contact information and signature

The key is precision. The full structure, and the lines worth avoiding, are in the clinician's guide, and the ESA letter template gives you the section-by-section version you can copy.

Do not write:

"This patient is legally entitled to have this animal everywhere."

Instead, identify the clinical opinion you can actually support.

Do not write:

"This animal is a service animal."

unless you are actually documenting a service-animal status within the applicable framework and have a basis to do so.

And do not write:

"HUD requires you to approve this animal."

That is a legal conclusion about a third party's obligation, not a clinical finding.

Does California AB 468 still apply?

Yes.

HUD's federal enforcement change does not eliminate state requirements.

California's AB 468 took effect January 1, 2022 and set specific requirements for health care practitioners who provide documentation about a patient's need for an emotional support dog. The California Board of Psychology lists five: hold an active license and include its effective date, number, jurisdiction and type in the documentation; be licensed in the jurisdiction where the documentation is provided, meaning where the client is; establish a client-provider relationship of at least 30 days first; complete a clinical evaluation of the need; and give the patient notice that fraudulently presenting a dog as a guide, signal or service dog is a misdemeanor.

The statute exempts clients verified to be homeless from the 30-day requirement.

California's Civil Rights Department has gone further since the HUD memo. In a legal alert dated July 20, 2026, it told housing providers and tenants that state fair housing law still requires housing providers to allow emotional support animals that have not been trained or certified, despite HUD's reversal. The department has also said separately that AB 468 did not change California fair housing law on reasonable accommodation and equal access to housing.

Sources: California Civil Rights Department legal alert, July 20, 2026 · California Board of Psychology on AB 468 · California Health and Safety Code § 122318

That is an important distinction.

A California clinician should not read the HUD memo and conclude:

"The federal government changed its policy, so California's ESA documentation requirements no longer matter."

They still matter.

Our guide to AB 468 has the full requirement list, the homeless exception and the compliance workflow. And AB 468 is only one example. Clinicians practicing elsewhere need to check the rules applicable to their own state and license.

What if state law is more protective than HUD's policy?

State law can continue to matter independently.

An FHEO enforcement memo does not preempt state or local fair housing law, and the memo does not claim to. California is the clearest illustration: HUD narrowed its enforcement in May 2026, and in July 2026 the state told housing providers that California law still requires them to accommodate untrained emotional support animals.

Sources: California Civil Rights Department legal alert (PDF) · Holland & Knight analysis, June 5, 2026

That means a clinician should not use a federal HUD update as a substitute for checking state law.

This is particularly important for clinicians who work across state lines through telehealth.

The relevant jurisdiction may depend on the patient's location, your professional license, the applicable state law, and the nature of the documentation being provided.

Before issuing an ESA letter, verify the requirements that apply to your practice and the patient.

Does this mean clinicians need to document animal training?

Not automatically.

The HUD memorandum's new enforcement standard focuses on whether the animal is individually trained to perform work or tasks directly related to the person's disability when determining which animal-related FHA complaints FHEO will pursue.

That does not mean a clinician writing a clinical letter should suddenly certify animal training.

Animal training is a separate factual question.

If you did not train the animal, observe the animal's training, or otherwise have a legitimate professional basis to make that determination, do not certify it.

Your role is to document the clinical facts within your scope.

If a patient needs documentation about an animal's training or service-animal status, that is a different question from whether the patient's clinical condition creates a disability-related need for an animal.

What happens if a housing provider rejects an ESA letter?

A rejected letter does not automatically mean that the clinician wrote an incorrect letter.

Housing accommodation decisions can involve questions beyond the clinician's clinical opinion.

The housing provider may be evaluating:

• Whether the person has a disability
• Whether there is reliable information supporting a disability-related need
• Whether the requested accommodation is reasonable
• Whether another legal framework applies
• Whether state or local law provides additional requirements
• Whether there are individualized facts concerning the particular animal

A provider may also ask for reliable information when the disability or the disability-related need is not obvious. Several states now spell out what that means: Florida's statute, for example, accepts information from a licensed practitioner with personal knowledge of the person's disability, and says an online registration or certificate is not enough by itself.

A clinician should therefore avoid promising a patient that a letter guarantees approval.

The letter establishes your clinical opinion.

It does not control the entire accommodation process.

What should clinicians document in the chart?

Your chart should show how you reached the conclusion.

A useful ESA documentation structure includes:

This matters more now because the old HUD guidance should no longer be treated as your documentation checklist.

The withdrawn guidance contained detailed documentation practices. But HUD's Federal Register withdrawal states that those documents were removed from active use and should not be relied upon as authoritative.

Use your clinical standards, applicable professional requirements, current law, and your practice's documentation policy instead.

What should clinicians do differently right now?

The practical response is not to stop writing ESA letters.

It is to tighten the workflow around them.

1. Verify the purpose first

Ask whether the letter is for housing or another setting.

Do not assume that an ESA letter carries the same meaning across housing, public accommodations, employment, school, and air travel.

2. Assess before documenting

Do not start with the patient's requested wording.

Start with the clinical assessment.

3. Separate clinical facts from legal conclusions

Document what you know and what you conclude clinically.

Avoid declaring what a landlord, airline, employer, or government agency must legally do.

4. Check state requirements

Review the rules applicable to your license and the patient's location.

For California clinicians, AB 468 remains particularly important because it imposes specific requirements on practitioners providing documentation concerning an emotional support dog.

5. Keep the letter focused

A housing accommodation letter does not need to become a copy of the patient's chart.

Document enough to support the professional opinion without unnecessary disclosure.

6. Recheck regulatory sources

This area is moving.

HUD has indicated that it intends to engage in notice-and-comment rulemaking concerning its regulations, so the May 2026 enforcement posture should not be treated as the final word on the federal regulatory framework.

How AI can help with ESA documentation

AI can help clinicians organize an ESA assessment and draft documentation, but the clinician remains responsible for the clinical conclusion.

That distinction becomes particularly important during a regulatory transition.

A documentation tool can help structure information about symptoms, functional impact, the patient's relationship with the animal, the requested accommodation, and the clinician's rationale. It can also flag missing fields or language that appears to make an unsupported legal claim.

For example, AI can help identify a sentence such as:

"This letter guarantees that the patient may keep the animal in any housing situation."

and flag it for review because it goes beyond a clinical statement.

What AI handles well

AI is useful for:

• Turning structured assessment information into a letter draft
• Organizing clinical reasoning
• Standardizing practice-approved templates
• Checking whether key fields are present
• Reducing repetitive administrative writing
• Flagging potentially overbroad language
• Separating clinical observations from administrative information

What the clinician must still decide

You should personally determine:

• Whether you have enough information to support the request
• Whether the patient has a relevant condition or disability
• Whether the animal has a clinically relevant relationship to that condition
• Whether the documentation is within your scope
• Whether state-specific requirements have been met
• Whether every statement in the letter is accurate

AI cannot resolve the legal uncertainty created by a changing regulatory framework.

It can help you document your assessment more consistently. It cannot make the assessment for you.

That is where Supanote fits. You record, dictate or upload the session, and it returns a structured note in a format you define, so the condition, the functional impact and the animal's role land in the same place every time. You edit in plain English and sign off before anything leaves your hands.

Supa builds the billing side for outpatient mental health practices as well, but for an ESA request the documentation is the whole product. A tool can organize the record, keep your template consistent across a caseload, and surface the fields you skipped. It cannot decide whether the clinical basis is there, and during a regulatory shift that judgement is the part that matters most.

ESA letter checklist after HUD's 2026 policy change

Before signing, ask:

• Purpose: Do I know exactly what the patient will use the letter for?
• Assessment: Have I independently evaluated the relevant clinical need?
• Function: Have I documented functional impact rather than relying only on diagnosis?
• Relationship: Do I have an appropriate clinical relationship with the patient?
• Jurisdiction: Have I checked applicable state and professional requirements?
• Accuracy: Can I personally support every factual statement?
• Scope: Have I avoided certifying animal training or legal rights I cannot establish?
• Confidentiality: Have I limited disclosure to information appropriate for the purpose?
• Patient education: Have I explained that an ESA letter is not the same thing as service-animal documentation?
• Review: Have I checked the current federal and state framework before signing?

If the answer to those questions is yes, the regulatory change does not require you to abandon your clinical documentation practice.

It requires you to be precise about what you are documenting.

Frequently asked questions

Did HUD ban emotional support animals?

No. HUD's May 22, 2026 memorandum changed FHEO's enforcement approach to animal-related reasonable-accommodation complaints. It did not amend the Fair Housing Act itself.

Did the Fair Housing Act change?

Not through the May 2026 memorandum. The memorandum is an agency enforcement document. The FHA remains federal law.

Can clinicians still write ESA letters?

Yes. The HUD memorandum does not tell clinicians to stop writing clinical documentation. Clinicians should continue to follow applicable professional, state, federal, and practice requirements.

Does HUD's new policy mean an ESA must be trained?

For FHEO enforcement, HUD says it will find reasonable cause and recommend charges only in animal-related accommodation cases involving animals individually trained to perform work or tasks directly related to the complainant's disability. That is an enforcement standard, not an amendment to the FHA's statutory text.

Should clinicians certify that an ESA is trained?

No, not unless they have an appropriate factual and professional basis to do so. A clinician's role is generally to document the clinical need within their scope, not certify animal training they have not independently established.

Does the HUD memo eliminate ESA protections?

That conclusion goes beyond what the memorandum itself establishes. HUD changed its enforcement posture, while the statute remains in place and private litigation and state-law claims are not eliminated by the memo.

Does AB 468 still apply in California?

Yes. California's AB 468 continues to impose requirements on health care practitioners providing documentation concerning an individual's need for an emotional support dog.

Does AB 468 change California housing rights?

California's Civil Rights Department states that AB 468 did not change California fair-housing law concerning reasonable accommodation and equal access to housing. In July 2026 the department also said state law still requires housing providers to allow untrained emotional support animals, whatever HUD does with its own enforcement.

Should clinicians use the old HUD 2020 ESA letter checklist?

Not as current HUD authority. HUD's withdrawal notice says the 2020 guidance was withdrawn and should no longer be relied upon as authoritative.

Does an ESA letter make an animal a service animal?

No. An ESA letter should not be used to represent an emotional support animal as an ADA service animal. California's AB 468 also specifically addresses fraudulent representation of dogs as guide, signal, or service dogs. The Department of Justice is explicit that animals providing only comfort are not service animals under the ADA.

Does a clinician's ESA letter guarantee housing approval?

No. A clinician documents a professional opinion. The accommodation process can involve additional legal and factual questions.

What should clinicians do if they are unsure whether to write a letter?

Review the patient's clinical information, your professional scope, your state's requirements, the purpose of the request, and your practice policy. If the clinical basis is insufficient, document that determination rather than signing a conclusion you cannot support.

What this update means in practice

The biggest mistake would be to read HUD's May 2026 memo as either a complete repeal of ESA housing protections or as a change that has no practical effect.

Neither description is precise.

HUD withdrew its 2020 assistance-animal guidance and adopted a substantially narrower enforcement standard. FHEO now says it will pursue reasonable-cause findings for animal-related accommodation complaints only when the animal has been individually trained to perform work or tasks directly related to the person's disability.

But the Fair Housing Act itself was not amended by that memorandum. Private litigation remains possible, state and local laws remain relevant, and HUD has indicated that further rulemaking is contemplated.

For clinicians, the response is therefore straightforward:

Keep assessing patients. Keep documenting clinical opinions you can support. Keep following state-specific requirements. But do not treat an ESA letter as a universal legal certification.

That distinction will matter even more while the federal regulatory picture continues to develop.
