What Happens After You Submit an ESA Letter for Housing? (2026 Guide)

In September 2025 HUD withdrew its earlier assistance-animal guidance, and in May 2026 it changed how it enforces animal-related accommodation complaints under the Fair Housing Act. Several states also now regulate who may write an ESA housing letter and when. This guide explains what happens after you submit, what a landlord may verify, which federal and state laws apply, and what to do if your request is delayed or denied.

Keeping your animal's vaccination, licensing and vet records together makes the review easier. Our free 15-page Pet Care Planner sample is built for exactly that.

Key Takeaways

• Federal enforcement changed, the statute did not. HUD's May 2026 memorandum focuses HUD's own enforcement on individually trained animals. Congress has not amended the Fair Housing Act.
• No fixed federal deadline. A response within about 10 business days is common practice, not a legal rule. An unreasonable delay can still amount to a denial.
• Privacy limits remain. A landlord may ask for reliable information about a disability-related need, not your medical records, treatment notes or diagnosis.
• State law matters more. California, Florida, Arkansas, Louisiana, Iowa and Montana regulate ESA documentation, and state agencies enforce their own fair housing laws.
• Pet fees are less settled. Under HUD's May 2026 memorandum, a request to waive pet rules (which can include pet fees) for an untrained ESA is not presumptively reasonable; state and local law and your circumstances decide.

What Happens After You Submit an ESA Letter: Step by Step

No statute sets a countdown, but most requests follow the same five steps.

1. 1Submit in writing and keep proof. Send your ESA letter with a short written reasonable accommodation request through a channel that leaves a record, such as a resident portal, email or certified mail. A landlord may offer its own form, but you should not have to disclose your diagnosis on it.
2. 2The landlord logs and reviews the request. Management checks that the letter shows the provider's license type, number and state, the date, a signature, and a statement connecting your disability-related need to the animal.
3. 3Verification. The landlord may look up the license on the state licensing board's website and may contact the provider to confirm they wrote the letter.
4. 4Follow-up questions. If the letter is incomplete, the landlord can ask for clarification. An updated letter from your provider usually resolves this.
5. 5A written decision. The landlord approves, approves with conditions such as proof of vaccination, suggests an alternative, or explains why the request is denied.

Many property managers aim to respond within about 10 business days, but that is internal practice, not a legal deadline. The 2004 HUD and Department of Justice Joint Statement on reasonable accommodations, which was not among the guidance HUD withdrew in 2025, says an undue delay in responding may be treated as a failure to provide a reasonable accommodation. Federal appeals courts have treated long delays the same way; in Bhogaita v. Altamonte Heights Condominium Ass'n (11th Cir. 2014), months of delay and repeated requests for information the association already had amounted to a constructive denial. Iowa law also requires a response within a reasonable amount of time.

If two weeks pass in silence, follow up in writing, and ask the landlord to confirm that pet-policy enforcement is paused while your request is pending — nothing in federal law pauses it automatically.

How Landlords Verify an Emotional Support Animal Letter

Online sellers of instant certificates have made landlords cautious. Three verification methods are common:

• License checks. The landlord confirms the provider's license is active and held in the state where they practice. Some states, including California and Montana, require a license valid in that state.
• Provider confirmation. A landlord may ask whether the provider wrote and signed the letter. Your provider cannot share your diagnosis or notes without your written authorization.
• Third-party screening platforms. Some properties route letters through outside services that may charge a fee. Ask who pays before you upload anything, and keep a copy of every submission.

Registries, ID cards, vests and certificates bought online do not establish a disability-related need; Florida and Iowa law both say a registration is not sufficient on its own. A letter from a licensed provider who actually evaluated you is the document that counts. See what documents landlords require for an ESA.

The Federal Law That Still Applies

The Fair Housing Act treats a refusal to make reasonable accommodations in rules, policies, practices or services as discrimination when the accommodation may be necessary for a person with a disability to have equal opportunity to use and enjoy a dwelling (42 U.S.C. §3604(f)(3)(B)). HUD's regulation at 24 C.F.R. §100.204 gives a familiar example: a building with a no-pets rule must allow a blind tenant's guide dog. Section 504 of the Rehabilitation Act separately covers federally assisted housing.

The Americans with Disabilities Act (ADA) uses a narrower definition for public places: a service animal is a dog individually trained to do work or perform tasks for a person with a disability, and providing comfort or emotional support alone is not a task (28 C.F.R. §36.104).

Trained Animals vs. Emotional Support Animals: What It Means for You

HUD's federal enforcement now turns on training. A dog trained to perform tasks tied to your disability, such as interrupting panic symptoms or providing deep pressure during an episode, has the strongest federal footing. An untrained ESA does not, even with a valid letter.

That does not make your letter worthless. It remains key evidence in a state agency complaint or a private lawsuit. Ask your provider to explain how the animal helps with your disability-related needs, and never claim training your animal has not received — several states penalize misrepresentation.

To strengthen any request, use a provider licensed in your state, make sure the letter shows the date and license details, make the request in writing, and have your animal's vaccination and local license records ready. Landlords may ask every animal owner for those routine records; our free Pet Care Planner sample keeps them in one place.

State Laws on ESA Housing Letters

Federal law sets a floor, and states may add documentation rules or broader protections. These states regulate the providers who write ESA housing documentation:

Other states protect tenants through their own fair housing laws and civil-rights agencies, some of which address assistance animals directly. Contact your state or local fair housing agency to learn what applies to you, and see ESA laws and requirements.

Whether a landlord may insist that your provider followed a state documentation statute is debated, because some of these laws regulate providers rather than tenants. The practical advice is simple: use a provider who follows your state's rules, and the question never arises.

Pet Fees, Deposits and Damage

HUD's withdrawn guidance had said housing providers could not charge pet rent, pet deposits or pet fees for assistance animals. For an untrained emotional support animal that expectation has weakened: under HUD's May 2026 memorandum, a request to waive pet rules, which can include pet fees, for an untrained ESA is not presumptively reasonable. Courts decide these cases on their own analysis. In Henderson v. Five Properties LLC (E.D. La. 2025), a federal court gave HUD's 2020 notice (since withdrawn) only persuasive weight and ruled against a tenant who had not shown that waiving a pet fee was necessary or reasonable, noting that the landlord had offered a payment plan; the court did not hold that ESA fees are always allowed. State and local rules may still limit these charges, so check before paying or refusing a fee.

If a landlord charges a fee, ask in writing for the legal basis. Whatever the outcome, you remain responsible for actual damage your animal causes, which a landlord may bill or deduct under the same rules as other tenant damage. Our guide to pet rent explains the different charges.

When a Landlord May Deny an ESA Request

• The property is exempt. The Fair Housing Act exempts units in an owner-occupied building with four or fewer units, and some single-family homes rented by an owner of no more than three such homes without a broker or discriminatory advertising (42 U.S.C. §3603(b)). State laws often cover these properties anyway.
• Direct threat. A landlord may refuse an animal whose tenancy would be a direct threat to the health or safety of others or would cause substantial physical damage to others' property (42 U.S.C. §3604(f)(9)). That should rest on the specific animal's actual conduct, not breed or size stereotypes.
• Undue burden. A landlord may deny a request that would impose an undue financial and administrative burden or fundamentally alter its operations.
• Unreliable documentation. Missing license details, an unlicensed author or a registry certificate can justify a request for better information.
• Untrained animal and federal enforcement. HUD may not pursue a complaint about an untrained ESA, but state agencies and courts may still hold a landlord accountable.

What to Do If Your Request Is Delayed or Denied

1. 1Follow up in writing. After about two weeks, send a polite email that references the date you submitted your request.
2. 2Ask for the reasons in writing. Request the specific grounds for any denial.
3. 3Fix documentation gaps. If the letter lacks a license number or a date, ask your provider to reissue it.
4. 4Contact a fair housing organization or agency. Your state or local fair housing agency may act even where HUD will not. HUD still accepts housing discrimination complaints within one year of the discriminatory act (1-800-669-9777), though since May 2026 its enforcement for untrained ESAs is narrow.
5. 5Get legal advice about a lawsuit. A private Fair Housing Act lawsuit generally must be filed within two years (42 U.S.C. §3613). A fair housing center, legal aid office or attorney can assess your case.

The Fair Housing Act also prohibits retaliation against people who exercise their fair housing rights (42 U.S.C. §3617). Do not move an animal in before approval, since that can invite a lease-violation notice. If a denial arrives, our guide on the ESA housing approval process walks through the next steps.
