ESA Fraud in Multifamily Housing: How to Spot It and What to Do
ESA fraud in multifamily housing is not a fringe problem. Renters can purchase ESA letters online for as little as $99, complete with a money-back guarantee, and use them to bypass pet fees, deposits, and breed restrictions.
That financial motive is clear; the cost of a letter is nothing compared to the hundreds or thousands of dollars a resident saves over a lease term. For operators who lack a consistent verification process, fraudulent requests are not easy to catch and even harder to act on without triggering a fair housing complaint.
This post gives property managers and housing operators a practical guide to recognizing fraudulent ESA documentation, understanding what the law actually allows you to ask for, and building a process that holds up under scrutiny.
Why ESA Fraud Is Growing in Multifamily Housing
The combination of low cost, high financial payoff, and inconsistent enforcement has turned ESA fraud into an organized problem. One provider was found issuing more than 1,700 ESA letters per month, generating over $1.5 million annually from online sales alone. That is not a resident gaming the system. That is a supply chain built specifically for it.
For property operators, the downstream effects go beyond lost pet revenue. Fraudulent ESA claims create liability exposure when untrained animals cause incidents, generate resentment among residents who follow the rules, and put leasing teams in a position where they must choose between pushing back and risking a fair housing complaint. Without a structured process, most teams default to approval because the risk of denial feels larger than the cost of the letter.
According to the National Multifamily Housing Council, 93.3% of its member organizations experienced renter fraud in 2023, and the tactics have grown more organized since. Snappt’s 2026 Multifamily Fraud Report, which analyzed more than 1.4 million applicant submissions, found an average fraud rate of 5.1% across the industry, with template-driven document fraud emerging as the dominant method. ESA letters fit the same pattern: easy to produce, hard to challenge, and increasingly difficult to distinguish from legitimate documentation without a verification framework in place.
What HUD’s 2025 Guidance Withdrawal Actually Changed
HUD withdrew its detailed ESA implementation guidance, FHEO Notice 2020-01, effective September 17, 2025. The Fair Housing Act itself was not changed.
The primary change is the removal of the detailed federal framework that previously outlined best practices for verifying documentation, assessing disability-related need, and determining when pet fees could be charged. For operators, this creates a gap. The underlying obligation to make reasonable accommodations still exists. The detailed roadmap for how to do that no longer does.
Properties that built their ESA process around the 2020 guidance now need to establish their own defensible internal framework. Properties that never had a structured process are now operating in a legal environment with fewer federal guardrails than before. That increases both the risk of inconsistency and the risk of a fair housing complaint.
The fair housing obligation has not gone away. Only the detailed federal instruction manual has.
Red Flags in Fraudulent ESA Documentation
Most fraudulent ESA letters share a consistent set of characteristics that leasing teams can be trained to recognize. Not every red flag means automatic denial, but each one justifies a closer review before approval.
Documentation Red Flags
- Letter issued by an online provider with no established patient relationship
- Three-minute questionnaire or online survey as the only interaction with the provider
- Generic template language with no specificity about the resident’s disability-related need
- Letter includes a certificate, registration number, or ID card as the primary proof
- Provider website offers a money-back guarantee or same-day letter delivery
- No mention of how long the provider has treated the resident
- Letter is dated the same week as the accommodation request
Animal Behavior Red Flags
- Animal is poorly socialized or shows aggressive behavior during move-in
- Resident cannot describe any disability-related function the animal serves
- Request includes multiple animals for a single disability claim
- Animal matches a breed or size that would otherwise trigger a significant pet fee
The presence of any one of these does not authorize denial. It does authorize a request for additional, reliable documentation, which is a distinction that matters when a fair housing complaint is filed.
Red Flag Summary
| Red Flag Category | What to Look For |
|---|---|
| Provider relationship | No established patient-provider history, online-only interaction |
| Documentation format | Certificates, registrations, or ID cards as the primary document |
| Letter content | Generic language, no disability-related nexus stated |
| Commercial signals | Money-back guarantee, same-day delivery, high-volume provider |
| Animal behavior | Aggression, no apparent disability-related function |
| Request scope | Multiple animals, same-day submission with application |
What Property Managers Can and Cannot Ask For
Housing operators can request reliable documentation when a disability and the disability-related need for the animal are not observable. That is the governing standard under the Fair Housing Act, even after the withdrawal of the 2020 guidance.
What “reliable” means matters here. HUD has been clear that documentation from websites that sell certificates, registrations, and licensing documents to anyone who answers certain questions or participates in a short interview is not automatically reliable. A letter from a licensed mental health professional with an established patient relationship is a different document than one generated by an online platform after a brief questionnaire.
What You Can Ask For
- A letter from a licensed healthcare or mental health professional who has personal knowledge of the resident
- Confirmation that the provider has an established relationship with the resident
- A statement that the resident has a disability affecting a major life activity and that the animal is necessary because of that disability
What You Cannot Ask For
- Medical records or a specific diagnosis
- Details about the severity of the disability
- Notarized statements or statements under penalty of perjury
- Certification, training records, or vest documentation for the animal
- A specific form completed by the healthcare provider
Online registrations and certifications can be handed back to the resident with a clear explanation that they are not adequate to verify the need for an assistance animal under the Fair Housing Act. What the property needs to know is whether the resident is disabled, whether they meet the definition of disability, and whether the animal is necessary to assist them because of that disability.
Documentation Standards at a Glance
The summary of all documents that are needed in this case along with how acceptable they are is given below
| Document Type | Acceptable | Notes |
|---|---|---|
| Licensed mental health professional letter (established relationship) | Yes | Must confirm disability and disability-related need |
| Online ESA certificate or registration | No | Not reliable documentation |
| ID card or vest documentation | No | Not a substitute for a clinical letter |
| Generic template letter | Requires review | Verify provider relationship before deciding |
| Letter from telehealth provider (brief questionnaire only) | No | No established patient relationship |
Building a Verification Process That Holds Up
A consistent, documented process is the difference between a defensible decision and a fair housing complaint. Properties that approve every request to avoid conflict and properties that deny every request to avoid liability are both exposed. The defensible position is a structured, evenly applied evaluation standard.
Step 1: Standardize the Request Form
Every ESA accommodation request should come through the same written channel with the same information fields: name, unit, date, type of animal, and a request for supporting documentation from a licensed professional with personal knowledge of the resident.
Step 2: Evaluate the Documentation Against a Consistent Checklist
Review every letter for the same criteria: licensed professional, established relationship, statement of disability, and statement of disability-related need. Apply the same standard to every request, regardless of who is on shift or which leasing agent is handling it.
Step 3: Request Additional Information When Warranted
If the letter fails the reliability checklist, send a written request for additional documentation before making a decision. Specify exactly what is missing. Give the resident a clear, reasonable timeframe to respond.
Step 4: Document Everything Before You Decide
Log the request date, the documentation received, the evaluation outcome, any follow-up requests, and the final decision. If a complaint is ever filed, this record demonstrates that the process was consistent and applied in good faith.
Step 5: Build Escalation Into the Workflow
Front-line leasing staff should not be the final word on requests that involve unusual documentation, multiple animals, or threats of legal action. A defined escalation path to a regional manager or legal counsel removes inconsistency and creates a second review layer.
The Cost of Getting It Wrong in Both Directions
Getting this wrong cuts both ways, and both directions are expensive.
Approving fraudulent ESA requests exposes the property to damage without fee coverage, resident conflicts when untrained animals cause incidents, and an implicit signal to future applicants that documentation is not evaluated.
Denying legitimate ESA requests exposes the property to fair housing complaints, HUD investigations, civil litigation, and compensatory damages. A 2022 case in Minnesota resulted in HUD charging a landlord for violating fair housing rights after refusing to accommodate a legitimate ESA request.
The goal is not to prevent ESA accommodation. It is to verify that each request meets the legal standard before granting it. Properties with a documented evaluation process, consistent training, and clear escalation paths are protected from both directions.
Conclusion
ESA fraud in multifamily housing is organized, accessible, and growing. The financial motive is large enough that some residents will attempt it. Leasing teams without a consistent evaluation framework will approve requests they should not, and sometimes deny requests they should not. Both outcomes generate costs.
A written process, trained staff, and documented decisions are what separate a defensible compliance record from a fair housing complaint waiting to happen.
Frequently Asked Questions
What makes an ESA letter fraudulent?
A letter is typically unreliable when it comes from an online provider with no established patient relationship, is generated after a brief questionnaire, or includes only a certificate or registration rather than a clinical statement.
Can property managers deny an ESA request?
Yes, when the documentation is unreliable, does not establish a disability-related need, or when the animal poses a direct, documented threat to health or safety.
What did HUD's 2025 guidance withdrawal change for multifamily operators?
The detailed federal verification framework was removed. The Fair Housing Act obligation to make reasonable accommodations for assistance animals remains fully in effect.
Can operators ask for the resident's diagnosis?
No. Operators can request confirmation of a disability and a disability-related need for the animal, but cannot request a diagnosis, medical records, or details about the severity of the disability.
Are online ESA certificates acceptable documentation?
No. Online certificates and registrations are not reliable documentation. A letter from a licensed professional with personal knowledge of the resident is required.
What happens if a fraudulent ESA causes property damage?
Damage claims can be pursued through the standard security deposit process. Properties without documented verification records are in a weaker position to recover costs because they cannot demonstrate that the accommodation was properly evaluated.
How often should ESA verification processes be reviewed?
At a minimum, annually, and immediately after any fair housing complaint, significant staff turnover, or changes to applicable state or local law.
