No government agency keeps a list of diagnoses that entitle someone to an emotional support animal. People search for that list constantly, and the reason they never find it is that federal housing law was written around functional limitation, not around diagnostic codes. Two people can share the same diagnosis and land on opposite sides of the line, because the test asks what the condition does to your daily life, not what it is called.
The actual legal test, in three parts
Fair housing law borrows its disability definition from the regulation at 24 C.F.R. § 100.201. Strip it to its working parts and you get three questions:
- Is there a physical or mental impairment? The regulation defines this to include “any mental or psychological disorder, such as … organic brain syndrome, emotional or mental illness, and specific learning disabilities,” and separately lists conditions like epilepsy, multiple sclerosis, diabetes, heart disease, and cancer on the physical side.
- Does it substantially limit a major life activity? The same regulation defines major life activities as “functions such as caring for one’s self, performing manual tasks, walking, seeing, hearing, speaking, breathing, learning and working.”
- Does the animal help with that limitation? This is the nexus, and it is the part most letters handle badly. A licensed provider has to be able to connect the animal to the impairment, not merely note that the person owns a pet and likes it.
Miss any one of the three and the request fails, no matter how real the underlying condition is.
Conditions clinicians document most often
Because the definition is functional, the categories below come up repeatedly in practice — but each one still has to clear the substantial-limitation step for the individual person:
- Anxiety disorders, including generalized anxiety and panic disorder
- Major depressive disorder and persistent depressive disorder
- Post-traumatic stress disorder
- Bipolar disorder
- Obsessive-compulsive disorder
- Autism spectrum disorder
- Phobias severe enough to restrict ordinary activity
- Chronic physical conditions whose management is complicated by psychological symptoms
Notice what is missing: ordinary stress, grief, a demanding semester, a rough year. Those are real experiences and they are not impairments under 24 C.F.R. § 100.201. A clinician who writes a letter for them is putting a license behind a claim that will not hold up, which is bad for the clinician and worse for the tenant relying on it.
What changed federally — and what did not
The assistance animal notice HUD issued in January 2020, FHEO 2020-01, was withdrawn by the Office of Fair Housing and Equal Opportunity with effect from September 17, 2025, alongside a 2013 notice covering similar ground. That step was published at 91 FR 17291.
That withdrawal matters for expectations rather than for entitlement. What survives is the part with legal force:
| Layer | Status |
|---|---|
| Definition of handicap, 24 C.F.R. § 100.201 | Unchanged |
| Reasonable accommodation duty, 24 C.F.R. § 100.204 | Unchanged |
| HUD-assisted housing animal exclusion, 24 C.F.R. § 5.303 | Unchanged |
| FHEO Notice 2020-01 and 2013-01 | Withdrawn, effective 2025-09-17 |
| State fair housing statutes | Independent of HUD guidance |
Two points follow for anyone assessing their own situation. First, the question was never really about a diagnosis label: 24 C.F.R. § 100.201 asks whether an impairment substantially limits a major life activity, and it names emotional or mental illness among qualifying impairments without listing which ones count. Second, a condition that is managed and currently stable can still qualify, because the same definition reaches a record of such an impairment and being regarded as having one.
The practical consequence is that state law now carries more of the weight than it did while the federal guidance was in place. Florida, New York, California, Texas and Pennsylvania each answer the qualifying question in their own statutes, and those answers did not move when the federal guidance was withdrawn.
Where your state changes the answer
State law is now doing more work than it has in years, and the four largest ESA markets do it four different ways.
Florida answers the qualifying question inside the statute. Fla. Stat. § 760.27 defines an emotional support animal as one that needs no training to provide therapeutic emotional support by its presence, and § 760.27(2) sets out what a housing provider may accept as reliable information — including a government disability determination, proof of disability benefits, or information from a licensed practitioner. Section 760.27(3) then bars the provider from asking for the diagnosis or severity at all. The Florida ESA rules go through that list in order.
New York uses a broader definition of disability than the federal one. N.Y. Exec. Law § 292(21) covers an impairment that prevents the exercise of a normal bodily function or is demonstrable by medically accepted clinical or laboratory diagnostic techniques — a lower bar than “substantially limits.” See the New York ESA guide for how that plays out with a landlord.
California does not change who qualifies, but it changes who may say so. Cal. Health & Safety Code § 122318 requires a 30-day client relationship and a completed clinical evaluation before a provider signs. That rule is covered in the California ESA guide.
Texas leans on the accommodation duty in Tex. Prop. Code § 301.025 rather than a dedicated ESA statute, because Tex. Hum. Res. Code § 121.002 defines assistance and service animals as canines that are specially trained — a definition that does not reach comfort animals. Details are in the Texas ESA guide.
Who is qualified to make the call
The determination belongs to a licensed professional who has actually assessed you — commonly a licensed clinical social worker, a licensed professional counselor or marriage and family therapist, a psychologist, a psychiatrist, or in many cases a treating physician. What matters is an active license and genuine knowledge of your condition.
The evaluation should look like clinical work: symptom history, duration, functional impact, what changes when the animal is present. If a website promises a determination from a multiple-choice quiz, no professional has made a judgment about you, and the resulting document carries the weight of the judgment behind it — which is none. Our walkthrough of how to get a legitimate ESA letter covers what a defensible document contains.
Two things that never qualify anyone
A purchased registration. There is no federal ESA registry, no state registry with legal force, and no certificate that establishes a disability. Florida wrote the point into statute at § 760.27(3)(c): an identification card, patch, certificate, or similar registration obtained from the internet is not by itself sufficient information. Every other state reaches the same result by simply having no registry to point to.
Wanting to skip a pet fee. The accommodation exists because a disability creates an unequal chance to use and enjoy a home. Someone with no impairment who wants a dog in a no-pets building is not being under-served by the law; they are outside its subject matter. Several states now criminalize claiming otherwise — Fla. Stat. § 817.265 makes falsifying ESA documentation a second-degree misdemeanor with 30 hours of community service, and Tex. Hum. Res. Code § 121.006 carries a fine of up to $1,000 plus 30 hours of community service.
If you think you qualify
Book a real evaluation with a licensed provider, describe the functional limits rather than leading with the animal, and let the clinician reach a conclusion. Ask whether they will document a disability-related need without disclosing your diagnosis, since housing providers are not entitled to it and several states forbid requesting it. Then check your own state’s statute, because in 2026 that is where the enforceable answer increasingly lives.
Frequently Asked Questions
Is there an official list of conditions that qualify?
No federal agency publishes one. The regulation at 24 C.F.R. § 100.201 describes categories of impairment rather than diagnoses, so the question is always whether a particular person's condition substantially limits a major life activity.
Does anxiety count as a qualifying condition?
It can, but the label alone decides nothing. A clinician has to be able to say the condition substantially limits something like sleeping, concentrating, working, or caring for yourself, and that the animal helps with that limitation.
Can a primary care doctor sign the documentation?
Often yes. The standard asks for a licensed professional with knowledge of the disability, not for a specific specialty. Some states narrow this further, so check your state's rule before booking the appointment.
Did HUD withdrawing its guidance change who qualifies?
It did not change the statutory definition of disability. It changed which complaints HUD will pursue, shifting the federal agency's focus to animals trained to perform disability-related tasks rather than to the underlying diagnosis.
