Service Animals vs Emotional Support Animals: What Your Landlord Can and Cannot Do

There is probably no area of rental housing law more misunderstood by both renters and landlords than assistance animals. Landlords think they can deny ESAs because their building has a no-pets policy. Renters think an online certificate from a website makes their pet an ESA. Property managers confuse service dogs with emotional support animals and apply the wrong rules to both. The result is a constant stream of disputes, wrongful denials, and unnecessary conflicts — many of which could be avoided by simply understanding what the law actually says.

This guide covers what you need to know accurately, including the recent federal policy change that every renter with an assistance animal should understand right now.

The Actual Difference Between a Service Animal and an ESA

These two categories sound similar but are legally distinct, with different protections, different documentation requirements, and different rights in housing.

The single most important practical distinction: service animals have both ADA and FHA protection, making them significantly harder for landlords to challenge. ESAs have FHA protection in housing only — and that federal protection is now substantially weakened at the enforcement level. If your animal is trained to perform a specific disability-related task, make sure your accommodation request clearly describes what that task is. This distinction is now more important than before.

What Changed in May 2026 — and What Did Not

On May 22, 2026, HUD's FHEO Assistant Secretary signed an enforcement guidance memo making these changes effective immediately:

• Cancels prior HUD ESA guidance permanently. The two guidance documents that told landlords how to handle ESA requests since 2013 and 2020 are gone.
• Replaces ESA standard with ADA service animal standard. HUD will only pursue fair housing complaints for animals individually trained to perform disability-related tasks.
• Puts existing ESA complaints on hold. Cases already under investigation will be reviewed under the new standard and most will likely close.
• Does not change the Fair Housing Act itself. The law still requires reasonable accommodations for disabled people. HUD has simply decided not to enforce it for untrained ESAs — but you can still sue in court.

What did not change:

• Service animal protections are completely unaffected. ADA protections do not run through HUD. Nothing in this memo touches service animal rights.
• State laws are completely unaffected. California, New York, Illinois, Washington, New Jersey, and many other states have independent fair housing laws with their own ESA protections.
• Your right to sue in federal court is preserved. The HUD memo explicitly preserves private lawsuits under the Fair Housing Act.
• Section 504 of the Rehabilitation Act is unaffected. Public housing and federally assisted housing tenants have additional rights under Section 504 that are separate from FHA.

What Your Landlord Can and Cannot Ask or Do

Breed and size restrictions do not apply to service animals. A landlord with a no-pit-bull policy or a 25-pound weight limit cannot apply those restrictions to a trained service animal. Courts have been consistent on this, and the ADA includes no size or breed exceptions.

This confusion is extremely common. A service dog handler does not need an ESA letter from a therapist. They also do not need certification papers, because no such certification exists in the US. For a service dog in housing, a landlord may ask only two questions: Is this a service animal required because of a disability? What work or task has the dog been trained to perform? That is the legal limit of what they can ask.

Documentation: What Is Real and What Is a Scam

This is where renters most often make expensive mistakes. The online ESA industry has created enormous confusion by selling ESA certificates, registration numbers, and official ID cards that have no legal standing whatsoever. There is no federal certification for ESAs. There is no official ESA registry. Any website selling these documents is selling you something worthless.

What Valid ESA Documentation Actually Is

A legitimate ESA letter comes from a licensed mental health professional — a therapist, psychiatrist, psychologist, or licensed clinical social worker — who has actually evaluated and treated you. The letter should be on their professional letterhead, include their license information, state that you have a disability-related need for the animal, and be signed and dated. The professional does not need to disclose your specific diagnosis or the nature and extent of your disability.

When a Landlord Can Legitimately Deny Your Request

Direct threat. If your specific animal poses a documented direct threat to the health or safety of others that cannot be reduced by reasonable means, a landlord can deny. This must be specific to your particular animal — not a general assumption about a breed or species.

Substantial physical damage. If allowing the animal would cause substantial physical damage to the property that cannot be reduced by reasonable means, the landlord may deny. Again, specific to the particular animal and property.

FHA exemptions. Owner-occupied buildings with four or fewer units are partially exempt from the Fair Housing Act under the Mrs. Murphy exemption. Single-family homes rented without a real estate agent are also partially exempt. Small independent landlords may have more legal latitude than large property management companies.

State Protections That Still Apply Regardless of HUD

The most important thing to understand about the May 2026 HUD change: it only affects federal enforcement. State fair housing laws are entirely independent and unaffected. Many states have protections that equal or exceed the prior federal standard.

Can Your Landlord Charge Pet Fees for Your Assistance Animal?

For service animals: landlords still cannot charge pet fees or deposits. This is protected by both the ADA and FHA, neither of which changed. This remains a hard rule with strong enforcement mechanisms.

For ESAs: the federal position has shifted. HUD attached a court case (Henderson v. Five Properties LLC) to its memo, signaling that requiring a disability-specific showing before waiving pet fees is acceptable at the federal level. Landlords who charge pet fees for untrained ESAs face much less risk of federal enforcement consequences than before May 2026.

However, in states with independent protections — California, New York, Illinois, Washington, and others — the prior rule against pet fees for ESAs is still enforceable under state law. If your landlord charges a pet fee for your ESA in one of those states, your complaint path runs through your state civil rights agency, not HUD.

That renter's situation highlights exactly the confusion the HUD change creates. Under the old framework, the answer was a simple no. Under the current framework, the answer depends on Indiana state law — and whether the renter pursues it through state channels rather than HUD.

What To Do If Your Landlord Denies Your Request

Step 1: Make your request in writing. Put your accommodation request in writing. State that you have a disability, that the animal assists with that disability, and that you are requesting a reasonable accommodation under the Fair Housing Act and your state's fair housing law. Cite your state law by name. Keep a copy.

Step 2: Provide appropriate documentation. For a service animal, answer the two permitted questions. For an ESA, provide a letter from your treating licensed mental health professional on their letterhead. Do not provide medical records or explain your diagnosis unless you choose to.

Step 3: If denied, contact your state's civil rights or fair housing agency. This is now the primary enforcement path for ESA holders. In California, file with the Civil Rights Department at calcivilrights.ca.gov. In New York, file with the Division of Human Rights. In Illinois, file with the Illinois Department of Human Rights.

Step 4: Contact a fair housing or disability rights organization. These organizations can evaluate your situation and in some cases advocate on your behalf at no cost. The National Fair Housing Alliance can help locate local organizations. DREDF provides resources specifically for disability-related housing discrimination.

Step 5: Consider a private lawsuit. The Fair Housing Act's two-year statute of limitations has not changed. You can file suit in federal or state court. The HUD memo explicitly preserves this right.

The Bottom Line

The legal landscape for emotional support animals is more uncertain now than it was one year ago. The federal enforcement mechanism most tenants relied on has been significantly weakened. That is the honest reality of the May 2026 HUD change.

At the same time, the Fair Housing Act itself still exists. State laws in California, New York, Illinois, Washington, and many other states remain fully intact. Service animals are completely unaffected. Private lawsuits remain available. The path to enforcement runs more through state agencies and courts than through HUD — but the path still exists.

If you have an ESA, the most important things you can do: make sure your documentation comes from a genuine treating mental health professional, know which state you live in and what independent protections your state provides, and make your accommodation request in writing citing your state's fair housing law by name. None of those things require a lawyer, and all of them significantly improve your position if a dispute arises.
