There is a version of the HUD May 22, 2026 memo story that is being told as good news for housing providers. HUD is pulling back. Emotional support animals are no longer treated the same as service animals at the federal level. Some of the headlines make it sound like the compliance problem has been resolved.
It has not been resolved. It has shifted. And for the compliance and operations leaders actually responsible for what happens when a Fair Housing complaint lands, the shift creates as many questions as it answers.
This post is about the documentation and verification questions that do not change regardless of what HUD does and the ones that just got more complicated.
What the Memo Actually Changes (From a Liability Standpoint)
HUD’s FHEO will no longer prioritize investigating complaints where the only issue is an ESA accommodation denial. That is the core of the May 22 memo. It also states that FHEO no longer expects housing providers to categorically extend the same accommodations for untrained ESAs that they extend for trained service animals.
This does not mean ESA denials are risk-free. It means the enforcement body most likely to investigate them is changing its posture. The risks that remain are at the state level, in civil courts, and in the documentation record you create every time an accommodation request comes through your properties.
More than half of U.S. states have ESA-specific statutes that were drafted around the old HUD guidance. In those states, your state civil rights department will still investigate complaints. Your legal exposure has not changed. In states without ESA-specific statutes: Idaho, Michigan, Texas, and Alaska are cited examples there is more room to treat ESA requests as standard disability accommodation requests rather than categorical exemptions from pet policies. But even in those states, the process matters enormously.
The memo shifts federal enforcement priority. It does not create a safe harbor for denials that lack documentation. A denial without evidence is still a denial without evidence, regardless of what HUD is prioritizing.
The Documentation Standard That Protects You
Housing providers have the right to request reliable documentation for assistance animal accommodation requests. That right is well established. What is less well understood is what “reliable” means in practice, and what the documentation needs to contain.
A letter meets the standard when it confirms two things: that the resident has a physical or mental impairment that substantially limits one or more major life activities, and that there is a disability-related need for that specific animal. Both must be present. A letter that describes a health condition without establishing it rises to the level of a disability does not meet the standard. A letter that confirms a disability without establishing the nexus to the animal does not meet the standard.
The documentation should come from a licensed healthcare provider: a physician, therapist, licensed clinical social worker, or counselor. Someone professionally trained to evaluate and document disability.
What you cannot do, and this is where the liability typically appears: you cannot ask what the disability is. You can verify that a disability exists. You cannot probe the specifics. You cannot require a specific form, a specific submission method, or a specific format. You cannot let requests sit without a timely response. And you must engage in the interactive process if documentation is incomplete, you respond with what is missing and give the resident an opportunity to provide it.
Every communication in the verification process should be in writing. If a call is necessary, record it. “The property manager asked me what was wrong with me” is a complaint you cannot defend without documentation of what was actually asked.
The Fraud Epidemic and Why Evidence Is Non-Negotiable
The documentation standard matters even more given the scale of ESA letter fraud. OurPetPolicy processes thousands of ESA requests monthly across hundreds of thousands of units. Based on that volume, approximately 60% of requests come in with letters purchased from online ESA letter mills. The May 22 HUD memo cites these services as a primary driver of the policy change.
The problem for compliance teams is that these letters are signed by real licensed providers. You cannot simply call them fraudulent. You need evidence. And that evidence needs to be documented before any denial goes out.
The specific red flags that constitute evidence of an online-purchased letter:
- An expiration date exactly one year from issuance (present in about 95% of online-purchased letters, absent from about 90% of legitimate letters);
- An ESA “verification number” or QR code linking to a registry;
- Language referencing hotel, airline, or restaurant accommodation rights;
- No verifiable clinic address or provider contact information;
- Multiple template versions submitted at once;
- A letter running three to four pages of regulatory boilerplate that no practicing clinician has time to write.
A letter with a registry verification number can be declined without engaging the interactive process, because it does not meet the standard for reliable documentation. Every other flag requires documentation of your reasoning and an open interactive process.
The Edge Case That Creates the Most Exposure
One pattern worth understanding specifically: some licensed providers who write letters for online services also have legitimate patients. OurPetPolicy identified one licensed social worker writing approximately 1,700 ESA letters per month in a single state while operating a small legitimate practice.
If you deny a letter from that provider because of the volume pattern, and one of their legitimate patients files a complaint, the question at investigation is whether you kept the interactive process open. If you denied and closed the process without allowing the resident to demonstrate the legitimacy of the relationship, you may lose that case even with strong evidence on the fraud side.
Deny with evidence. Document the evidence. Keep the interactive process open. Those three steps, applied consistently, are what a defensible process looks like.
What Your Process Audit Should Cover
Given the current environment, here is the compliance audit checklist for your ESA process:
- Documentation intake: Does every accommodation request, regardless of how it arrives, get logged and timestamped within 24 hours?
- Completeness review: Do you have a written standard for what a complete submission looks like, and does every site team apply it consistently?
- Fraud flag documentation: When a letter is identified as potentially online-purchased, is the specific evidence recorded before any denial is issued?
- Interactive process: Does every incomplete or declined submission receive a written response that specifies what was missing and invites the resident to provide it?
- State law mapping: Does your process differentiate between properties in states with ESA-specific statutes and those without?
- Audit readiness: If a complaint is filed 18 months from now, can you reconstruct every decision for every request at every property?
