Do ESA Cat Letters Expire? Renewal, Dates and What Landlords Check

Few questions reach us as often as this one: do ESA letters expire? Federal housing law does not print an expiration date on an emotional support cat letter, yet landlords routinely ask for documentation that is reasonably current, and several states layer on their own requirements. The answers below explain how renewal works, what a housing provider may check, and where state rules in every U.S. state change the picture.

The Basics: Expiration and Validity

1. Do ESA letters expire?

The Fair Housing Act does not set a federal expiration date for an ESA letter, and HUD's notice FHEO-2020-01 does not define one either. In practice, many housing providers and clinicians treat a letter as current for about one year, so a letter is often reissued on an annual cycle. Your clinician and your lease paperwork will tell you what is expected in your situation.

2. Why do most letters carry a one-year date?

A letter reflects a clinician's professional assessment at a particular point in time, and needs can change. An annual review is a widely followed convention rather than a federal rule, and it gives a landlord reasonable confidence that the information is up to date. Your licensed mental health professional (LMHP) will determine whether continuing an emotional support cat remains therapeutically appropriate.

3. Can a landlord reject a letter simply because it is a year old?

HUD guidance allows a housing provider to request reliable documentation when a disability or the need for an animal is not obvious, and an older letter may prompt such a request. Whether a particular rejection is lawful depends on the facts, so we cannot give legal advice here. If you receive a denial, consult a licensed attorney in your state or your local legal aid office, which can help with Fair Housing Act enforcement.

4. Does my cat's lease start date matter?

Generally, a landlord evaluates the accommodation request when you make it, so the letter should be reasonably current at that moment. Many tenants request the accommodation before signing a lease or before their cat moves in. Keeping your documentation up to date at renewal time can make later conversations simpler.

Renewal: Timing and Process

5. How does emotional support cat letter renewal work?

Emotional support cat letter renewal usually means a fresh check-in with a licensed clinician, who reassesses whether an emotional support animal remains appropriate for you. If the clinician agrees, they issue an updated letter with a new date. Our step-by-step guide to getting an ESA letter for your cat describes the same evaluation process that applies to renewals.

6. When should I start renewing?

Many people begin two to four weeks before their current letter reaches its one-year mark, or before a lease renewal. In the five states that require a 30-day clinician relationship, extra lead time helps, though an existing relationship may shorten the process. Starting early avoids a gap in documentation.

7. Is renewal automatic?

No. A licensed clinician evaluates each person individually, so renewal is never automatic and we never promise a particular outcome. Your circumstances may have changed, and the clinician will decide whether a letter is still appropriate.

8. Do I have to see the same clinician?

Not necessarily, although continuity is often smoother because your clinician already knows your history. The clinician must be licensed in the same state as you, and a few states add relationship requirements. Ask your provider how they handle returning clients.

9. What does renewal usually cost?

Pricing varies by provider and is set independently of the law. Be cautious of services advertising instant approval, guaranteed approval or a low flat fee with no clinician evaluation, because a legitimate letter requires a real assessment by a licensed professional.

State Rules That Affect Dates

10. Do ESA letters expire in Florida?

Florida Statute 760.27 does not, to our reading, print a statutory expiration date, but it does shape who may write a valid letter. The clinician must be licensed in Florida, or have an established prior in-person relationship with you, so online-only out-of-state providers cannot issue a valid Florida ESA letter. Because Florida providers may ask for reliable, current information, many tenants keep an annual letter on file.

11. Do ESA letters expire in Texas?

We are not aware of a Texas statute that sets a fixed expiration date for ESA letters in housing, so the federal Fair Housing Act framework generally governs. As elsewhere, a landlord may ask for reasonably current documentation, and a one-year-old letter is the common benchmark. For a specific Texas dispute, consult a Texas-licensed attorney.

12. Which states require a 30-day clinician relationship?

California (AB-468), Montana (HB-703), Arkansas, Iowa and Louisiana require an established therapeutic relationship of at least 30 days before the clinician can issue an ESA letter. This applies to a first letter and may apply when a relationship is being re-established, so check with your clinician. We view this as a protection that makes letters in those states more credible, and we do not promise faster turnaround there.

13. Does a state-specific rule mean my letter works only in that state?

Your letter should come from a clinician licensed in the state where you live. If you move to a new state, a clinician licensed there may need to evaluate you, since rules and licensing requirements differ. Review your new state's rules before relying on an old letter.

14. Do the other states have different expiration rules?

Most states follow the federal framework and do not fix an expiration date in statute, but laws change and some states have added provider requirements. Read your state's current rules, and consult a licensed clinician and, for disputes, a licensed attorney in your state.

What Landlords Actually Check

15. What can a landlord look for in my letter?

Housing providers commonly look for a signature, license type and state, the clinician's contact details, a date, and a statement connecting the animal to a disability-related need. They typically do not need your diagnosis, and HUD's FHEO-2020-01 notice discourages requests for medical records. Expect them to verify the clinician's license rather than ask about your health history.

16. Can a landlord charge a pet deposit or fee because my letter is renewed?

Under HUD guidance, an assistance animal is generally not treated as a pet for fee purposes, but you may still be responsible for damage your cat causes. Rules on specific charges can be nuanced. Confirm details with a licensed attorney or legal aid office in your state.

17. Do I need to register my cat?

No. Registration, ID cards and certificates are not a legal requirement, and housing rights under the Fair Housing Act come only from a letter written by a licensed mental health professional. Our optional registration service offers lifetime registration, a lost-pet recovery database, an ID card and certificate, and a discount on the letter; the lost-pet recovery benefit is the most practical. A landlord is never obligated to accept a registration number or card in place of your letter.

18. Will an ESA letter help me fly with my cat?

No. In 2021 the Department of Transportation removed emotional support animals from the Air Carrier Access Act, so airlines treat them as ordinary pets and apply their pet policies and fees. Only trained psychiatric service dogs retain those protections.

19. What if my landlord disputes my letter?

Stay calm, respond in writing, and keep copies of every exchange. Ask your clinician whether they can confirm the letter's authenticity, and contact a licensed attorney in your state or local legal aid about your options. We cannot provide legal advice.

Keeping Your Documentation Current

20. How should I store my letter?

Keep a digital copy and a printed copy, along with your original accommodation request and your landlord's written response. Note the letter's date in your calendar so you can plan renewal before it matters. Share only what is needed, and never post personal clinical information publicly.

21. Should I talk to my clinician if my circumstances change?

Yes. A move, a new housing provider or a change in your wellbeing can all be good reasons to check in. A licensed clinician will determine whether an emotional support cat is still therapeutically appropriate for you.

Whether an emotional support animal is appropriate for you is a decision made by a licensed mental health professional, and many people with anxiety, depression or similar concerns find an ESA helpful, though a clinician must evaluate your individual situation. Please consult a clinician licensed in your state, review your state's current ESA rules, and for housing disputes consult an attorney licensed in your state or your local legal aid office.
