Fake ESA Letters Have a Kill Switch Now. Most California Landlords Don’t Know How to Use It.

You enforce a no-pets policy. An applicant hands you an "Emotional Support Animal" letter they got online in twenty minutes. You know it's probably fake. But if you reject it and you're wrong, you're facing a fair housing complaint that starts at five figures.

If you accept it and the letter is fraudulent, you've just waived your pet policy for nothing and set a precedent for every future tenant. Either way, you lose -- unless you know exactly where the legal lines are.

The good news: California gave landlords real tools to fight fraudulent ESA letters. The bad news: the federal landscape just got a lot murkier. Here's how to handle ESA requests in 2026 without getting sued or getting scammed.

Pets, Service Animals, and ESAs Are Three Different Things

Treating all animals the same is the fastest way into a fair housing complaint. The law draws sharp lines between three categories, and your rights as a landlord are completely different for each one.

The critical distinction: service animals are trained to perform specific tasks (guiding the blind, alerting to seizures). ESAs provide emotional comfort but require no specialized training. Both are protected from pet fees and breed restrictions. But with ESAs, you have the right to verify the documentation -- and California law gives you specific criteria to measure it against.

The Federal Rulebook Just Disappeared

For years, landlords relied on HUD's guidance documents -- specifically FHEO Notices 2013-01 and 2020-01 -- to evaluate ESA requests. Those documents explained what documentation you could request, what questions you could ask, and how to distinguish legitimate ESAs from pets with fake certificates.

On September 17, 2025, HUD withdrew both guidance documents as part of a deregulatory initiative. They're no longer on the HUD website, and HUD stated they should not be relied upon while under review. This came after the Supreme Court's 2024 Loper Bright Enterprises v. Raimondo decision, which held that courts aren't bound by agency guidance that lacks persuasive legal support.

The practical result: a federal court in Louisiana (Henderson v. Five Properties, July 2025) ruled that a landlord could charge a standard animal fee for an ESA because the tenant couldn't demonstrate that waiving the fee was medically necessary. That decision was in the 5th Circuit -- not binding in California's 9th Circuit.

California's Anti-Fraud Law: AB 468

While the federal picture has gotten murkier, California sharpened its own rules years ago. Assembly Bill 468, effective since January 1, 2022, was written specifically to kill the ESA letter mill industry -- websites that sell official-looking certificates to anyone who fills out a five-minute questionnaire.

Under AB 468, a valid ESA letter in California must meet all four of these requirements:

1. 30-day established relationship. The healthcare provider must have an existing client-provider relationship with the tenant for at least 30 days before writing the letter. An instant online approval fails this test automatically.
2. Active California license. The provider must hold a valid, active license in California -- the state where the tenant lives. An out-of-state therapist's letter doesn't qualify. You can verify any California license online through the BREEZE system.
3. Real clinical evaluation. The provider must have completed a clinical evaluation of the tenant's need for an ESA. Phone or video consultations count. A web form questionnaire does not.
4. Fraud disclosure. The letter must include a notice to the tenant that misrepresenting an ESA as a service animal is a misdemeanor under California Penal Code Section 365.7, punishable by up to six months in jail and a $1,000 fine.

If a tenant hands you a letter that fails any of these four tests, you have the legal right to reject that specific document. But -- and this is where landlords get into trouble -- you can't just say "denied" and close the door.

The Interactive Process: How to Reject a Bad Letter Without Getting Sued

Fair housing law requires what's called the "interactive process." When an ESA letter is insufficient, you can't simply deny the request. You have to engage in a good-faith dialogue and give the tenant a chance to fix the problem.

Here's what that looks like in practice:

First, respond in writing. Tell the tenant exactly why the letter doesn't meet AB 468 standards. Be specific: "This letter does not demonstrate a 30-day client-provider relationship as required by California Health and Safety Code Section 122318." Don't say "your letter looks fake."

Second, give them a reasonable timeframe to obtain compliant documentation from a licensed provider. Two to three weeks is generally considered reasonable.

Third, document everything. Save every email, every letter, every text. If you end up facing a discrimination complaint, this paper trail is what proves you engaged in the interactive process instead of just shutting the tenant down.

The Mistakes That Cost $35,000

California's Civil Rights Department (CRD, formerly DFEH) actively investigates ESA-related fair housing complaints. The penalties are designed to hurt, and they do. A landlord in Bakersfield demanded a million-dollar insurance policy for a tenant's Pit Bull ESA -- the state forced a $35,000 settlement. A landlord in San Jose dismissed a tenant's medical letter, reportedly telling them they "didn't need a dog to survive." That cost $40,000.

Here are the specific violations that generate the biggest fines:

How We Handle ESA Requests at SLPM

At SLPM Property Management, every ESA request goes through the same process. No improvising. No guessing. Here's the workflow:

1. Treat every request as a formal accommodation. Whether the tenant walks in with a legitimate letter or a $50 internet certificate, we treat it as a fair housing accommodation request. The interactive process starts immediately.
2. Verify the provider's license. We look up the healthcare provider's California license through the state's BREEZE verification system. If it's inactive, expired, or out-of-state, the letter doesn't meet AB 468 standards.
3. Check all four AB 468 requirements. 30-day relationship, active California license, clinical evaluation, and fraud disclosure. If any element is missing, we respond in writing with the specific deficiency and give the tenant reasonable time to obtain a compliant letter.
4. Document the entire interaction. Every communication is saved. If a complaint is filed, our documentation proves good-faith engagement with the tenant throughout the process.
5. Never charge ESA fees. Once a valid letter is confirmed, the animal is accommodated with zero pet rent, zero deposit, and zero breed restrictions. We note the ESA in the tenant file and move on.
