“This letter isn’t valid” is a sentence that lands with more force than it deserves, because the person saying it usually cannot explain what “valid” would mean. There is no federal certification for assistance-animal documentation, no approved vendor list, and no seal. What exists is a reliability judgment — and reliability judgments can be reasonable or can be a pretext, so the first job is telling them apart.
Why housing providers reach for this objection
Two things converge. The market is full of sites that will sell a signed PDF after a two-minute questionnaire, so property managers have genuinely seen documents no clinician ever read. And the federal guidance memo that used to describe what documentation should look like was withdrawn: FHEO Notice 2020-01 and FHEO Notice 2013-01 were withdrawn effective September 17, 2025, published at 91 FR 17291.
The result is a gap. Managers who once quoted a HUD memo now improvise, and improvisation drifts toward demanding more than the rules allow.
The line the regulations draw
A provider is entitled to satisfy itself that a document is what it claims to be. It is not entitled to use that as a doorway into a medical file. Section 100.202(c) makes it unlawful “to make an inquiry to determine whether an applicant for a dwelling … has a handicap or to make inquiry as to the nature or severity of a handicap of such a person,” subject only to five narrow exceptions that must be applied to all applicants.
So the two categories look like this:
| Reasonable verification | Prohibited or unlawful demand |
|---|---|
| Confirming the signer holds an active license in the stated profession | Asking what your diagnosis is |
| Confirming the named professional actually issued the document | Asking for medical records or therapy notes |
| Asking that the document describe a disability-related need for the animal | Requiring a specific company’s form |
| Asking for legible contact details for the signer | Requiring a notarized statement |
| Asking about local licensing or vaccination for the animal | Demanding a registration certificate or ID card |
Florida wrote several of those into statute. Fla. Stat. § 760.27(3) bars a housing provider from requesting information that discloses the diagnosis or severity of a disability or any medical records, from requiring a specific form or a notarized statement, and from denying a request solely because the tenant did not follow the provider’s routine method.
The registry question, settled by statute
Anyone told to “get the animal registered” is being asked for something that does not exist in law. Florida says so directly: § 760.27(3)(c) provides that an emotional support animal registration of any kind — an identification card, a patch, a certificate, or similar registration obtained from the internet — is not by itself sufficient information to establish either a disability or a disability-related need for the animal.
Pennsylvania attacks the same products from the other end. Under § 6 of the Assistance and Service Animal Integrity Act, it is a summary offense punishable by a fine of up to $1,000 to fit an animal that does not qualify with a harness, collar, vest or sign of the kind used by assistance or service animals. Buying the kit is not a defensive move; in Pennsylvania it is an exposure.
Telehealth is not the problem people assume
A remote evaluation is not inherently weaker documentation. Florida’s statute at § 760.27(2)(b)4. contemplates information from a health care practitioner or telehealth provider, and sets its reliability condition elsewhere: an out-of-state practitioner counts only where that practitioner has provided in-person care or services to the tenant on at least one occasion, has personal knowledge of the disability, and is acting within the scope of practice.
Read carefully, that is not a rule against telehealth. It is a rule against a stranger in another state signing for someone they have never treated — which is the actual problem the “fake letter” complaint is usually gesturing at.
Audit your own document first
Before arguing, check whether the objection has a point. A document that can withstand scrutiny generally carries:
- An issue date
- The professional’s license type, license number, and licensing state
- A statement that you have a disability, without naming the diagnosis
- A statement that the animal is needed in connection with that disability
- A signature and contact details that resolve to a real practice
- A real evaluation behind it — a conversation, not a checkbox form
If items two, five or six are missing, the landlord is not being unreasonable, and the fix is a new document rather than a fight. Our guide to getting a legitimate letter walks through what a genuine evaluation involves.
State standards worth quoting back
| State | Standard | Citation |
|---|---|---|
| California | Licensed professional must hold a client relationship of at least 30 days and complete a clinical evaluation before issuing | Cal. Health & Safety Code § 122318 |
| Pennsylvania | Documentation must be in writing, reliable, based on direct knowledge, and describe the disability-related need | Assistance and Service Animal Integrity Act § 3(b) |
| Florida | Information from a practitioner with personal knowledge, acting within scope of practice; no form or notarization required | Fla. Stat. § 760.27 |
| New York | Documentation from a treating professional, who need not be a physician; no certification or training may be required | State assistance-animal guidance |
| Texas | Reliable documentation from a licensed professional describing the disability-related need | Tex. Prop. Code § 301.025 framework |
Pennsylvania’s “direct knowledge” phrasing is the sharpest of these, because it is precisely what a form letter from a provider who never assessed you fails. Details live on the Pennsylvania, California, Florida, New York and Texas pages.
Responding to the accusation
- Ask for the objection in writing, naming what specifically is doubted. “It looks fake” is not something you can answer; “the license number does not appear on the state board register” is.
- Offer verification, not records. The signer’s name, license number and licensing state let a provider check a public register on its own.
- Decline the diagnosis request by reference to § 100.202(c), in one neutral sentence.
- Do not supply a certificate. Offering one invites the argument that your case rests on a product with no legal weight.
- Set a date for a decision. Silence dressed as verification is a common stall, and a dated request converts it into a record.
Watch for the fee that follows
A verification demand sometimes arrives attached to a charge — a “documentation review fee,” an “assistance animal addendum” with a price on it, or a deposit collected while the review is pending. Section 100.65 makes it unlawful to impose different terms, conditions or privileges relating to the rental of a dwelling because of handicap, and it names using different lease provisions, including those relating to rental charges and security deposits, as prohibited conduct. Pay it under protest if you must to keep the tenancy, note the date, and put the charge in the record.
If the letter was bought from a mill
Some readers will recognize their own document in the description of a two-minute questionnaire. The right move is to replace it, starting with any clinician who already treats you.
There is also a reason not to double down. Several states criminalize misrepresentation: Fla. Stat. § 817.265 makes it a second-degree misdemeanor to falsify or knowingly provide fraudulent documentation for an emotional support animal under § 760.27; Pennsylvania’s Act 118 § 5 grades intentional misrepresentation of entitlement as a misdemeanor of the third degree; Tex. Hum. Res. Code § 121.006 and Cal. Penal Code § 365.7 reach misrepresenting an animal as a trained assistance or service animal. None of these punishes having a real need. All of them punish manufacturing evidence of one.
When the paperwork was never the issue
Sometimes the letter is clean, the license checks out, and the refusal stands anyway. At that point the dispute has changed character: it is a refusal to make a reasonable accommodation under 24 C.F.R. § 100.204, and a pet policy, a breed list, or a preference for not dealing with animals is not among the lawful grounds for a denial.
The federal administrative window is one year from the last incident under 24 C.F.R. § 103.35, and the complaint walkthrough sets out what to file and where. Keep the emails. In a documentation dispute, the sequence of who asked for what, and when, is usually the whole case.
Frequently Asked Questions
Can a landlord contact the professional who signed my letter?
Confirming that a named licensee wrote and signed a document is different from questioning them about your condition. Section 100.202(c) restricts inquiry into whether a person has a disability and into its nature or severity, and that limit follows the conversation.
Is a telehealth letter automatically weaker?
Not as a matter of law. Florida's statute expressly contemplates information from a health care practitioner or telehealth provider, and treats an out-of-state practitioner as reliable only after in-person care on at least one occasion.
Does buying an online certificate help if my letter is questioned?
It hurts. Florida's statute says an ESA registration of any kind obtained from the internet is not by itself sufficient proof, and Pennsylvania makes it a summary offense to fit a non-qualifying animal with a vest or sign of that kind.
What if the letter is genuine and the landlord still refuses?
Then the dispute is no longer about paperwork. A refusal to accommodate is the conduct 24 C.F.R. § 100.204 addresses, and it can be taken to HUD or a certified state agency within the applicable filing window.
