How a Landlord Verifies an ESA Letter?

If the information cannot be verified, landlords may request clarification from the licensed provider before making a decision. 

Let's walk through that checklist one step at a time, starting with the document itself.

The Step-by-Step Verification Process

Verification exists to catch fraudulent letters without penalizing genuine ones, so it protects tenants and landlords alike. A real letter from a licensed provider clears it easily, while a purchased certificate does not. Understanding how a landlord verifies an ESA letter also shows a tenant exactly what a legitimate letter needs. 

1. Review the Letter's Contents

A verifiable ESA letter should include the fields below. Each one is something a landlord can check.

• The tenant's full name.
• A clear statement that the tenant has a mental or emotional disability recognized in the DSM-5, without disclosing the full diagnosis.
• An explanation of how the animal helps ease the symptoms of that disability.
• The provider's name, license type, license number, and the state that issued the license.
• The provider's direct contact information and office address.
• Official letterhead from the practice or clinic.
• A recent issue date, generally within the last twelve months, since many housing providers treat a letter as current for about a year.

Every RealESALetter.com letter carries the clinician's state license number, issue date, and direct contact information, which are the same fields a landlord checks during verification. 

2. Verify the Healthcare Professional

The letter should come from a licensed healthcare professional, such as a psychiatrist, psychologist, or licensed therapist, who holds an active license in the tenant's state of residence. 

• Look up the provider's name and license number on your state's professional licensing portal, whether that is the medical, psychology, or social work board, and confirm the license is active. If the provider has a National Provider Identifier, the NPI Registry gives a second way to confirm their identity.
• Notice whether the letter came from an instant, pay-for-certificate website. Not every online service is invalid, but HUD has long noted that letters bought online without a genuine clinical assessment are frequently flagged as fraudulent.

3. Contact the Provider (If Necessary)

If real doubts about the letter's authenticity remain, you can reach out to the clinician's office to confirm they wrote it.

• Privacy tip: ask your tenant for permission first. Client confidentiality means a therapist can refuse to share anything unless the tenant has authorized them to speak with the landlord.

4. Know What You Can and Cannot Ask (Under Today's Rules)

There are still firm limits on what a landlord can request, and some of the older federal rules have shifted.

• What you can generally ask: veterinary records confirming vaccinations, and whether the animal poses a safety or noise risk.
• What you should not ask: detailed medical records or a specific mental health diagnosis. Many state laws and FHA privacy norms continue to bar this.
• What changed: the blanket federal rules that once said a landlord could never charge a pet fee, deposit, or pet rent for an ESA, and could never weigh training, came from HUD guidance that was withdrawn in 2025 and rescinded in May 2026. Whether fees apply, or a training standard is used, now depends on your state's law and the type of housing. Confirm your local rules before relying on the old "no fees, no training" position.

That is the mechanical process. What a landlord is actually allowed to verify, though, and how much a letter can compel, shifted in 2025 and 2026. Here is where the law stands today.

What a Landlord Can Verify Under Today's Rules (2025 to 2026 update)

The Fair Housing Act (42 U.S.C. § 3604) still makes it unlawful to discriminate in housing based on disability. Its reasonable accommodation duty has not been amended. What changed is HUD's guidance, the detailed playbook housing providers relied on for years.

On September 17, 2025, HUD issued a memo withdrawing two long-standing guidance documents. These were FHEO Notice 2013-01 and FHEO Notice 2020-01. Together they had explained how housing providers should assess a reasonable accommodation request involving an assistance animal. 

Then, on May 22, 2026, HUD's Office of Fair Housing and Equal Opportunity signed an enforcement memo that permanently rescinded that guidance. It set a much stricter enforcement standard. 

Going forward, HUD will find reasonable cause on a pet-policy-waiver accommodation only where the animal is individually trained to perform work or tasks directly related to the person's disability. That is the Americans with Disabilities Act definition of a service animal. It is a higher bar than an untrained emotional support animal has historically had to meet.

For verification, three things follow. First, the old HUD specifics that circulated for years are no longer current federal guidance. That includes claims like "landlords can never charge a fee," a fixed two-question script, and a rigid documentation checklist. 

A landlord cannot verify against them as if they were binding rules. Second, because the federal framework has narrowed, state and local law now carries more weight in deciding what a landlord may ask. Third, and this is what protects genuine ESA holders, the changes are limited to HUD's own enforcement. The FHA statute stands. 

Complaints under Section 504 of the Rehabilitation Act and the ADA are unaffected. State fair housing laws are unaffected. A tenant can still bring a private lawsuit in court without any HUD finding.

None of this is legal advice, and HUD has signaled it intends formal rulemaking to follow. Anyone relying on these rules for a specific situation should confirm the current posture. Where stakes are high, consult a housing attorney. 

Red Flags That Fail Verification

Most fraudulent letters share a handful of tells. Letters that show any of the following usually fail a verification check:

• Issued instantly with no clinical evaluation. This is a letter generated within minutes of an online quiz, before any real assessment.
• Only a "registration number" instead of a license number. ESA "registries," ID cards, and certificates are not recognized as proof of anything. There is no official ESA registry.
• A "paid-for certificate" or "certified ESA" language used in place of a licensed clinician's letter.
• No verifiable contact information or contact details that lead nowhere when checked.
• A provider not licensed in the tenant's state, where state law requires one.

Letters issued instantly without a clinical evaluation are the most common signs of a fake. So are letters that list only a registration number instead of a license number. 

How ESA Letter Verification Differs by State 

With federal HUD guidance withdrawn, state rules increasingly determine how a letter is verified. So the tenant's state matters more than it used to. License lookups differ board by board. Several states also layer on their own requirements.

Note that Florida does not impose a fixed 30-day waiting period. The 30-day relationship rule belongs to states like California, Montana, and Iowa. Others, such as Arkansas and Colorado, require an established treating relationship without a fixed number of days. Some states also criminalize fraudulent ESA documentation. 

Florida's § 817.265, for example, treats misrepresentation as a second-degree misdemeanor. RealESALetter.com letters are issued by state-licensed therapists after a genuine clinical evaluation. They comply with applicable state law and the federal Fair Housing Act.

Will Your ESA Letter Pass? A Tenant's Verification Self-Check

If you are the tenant, here is how to tell whether your letter would clear a landlord's authenticity check. Ask yourself whether your letter:

• Comes from a therapist licensed in your state, with the license type and number printed on it.
• Shows a license number you can find on your state board's public lookup, listed as active.
• Was issued after a genuine evaluation, not an instant online form.
• Is on letterhead with working contact information and a recent date.
• States a disability-related need without over-sharing your diagnosis.

An ESA letter passes a landlord's verification when it comes from a therapist with an active, verifiable license in the tenant's state and was issued after a genuine evaluation.

One honest caveat applies here, given the 2025 and 2026 changes. Passing an authenticity check is not the same as compelling an accommodation. A real, verifiable letter clears the "is this genuine?" question. Whether it obligates a particular landlord to waive a no-pets policy now depends on several things. 

It depends on your state's law, the type of housing, and whether the request falls under Section 504 or the ADA. At the federal level, HUD no longer treats an untrained ESA the way it did before May 2026. A genuine letter is still the foundation. But where you live now determines much of what it buys you.
