Start with your own clinician. An emotional support animal is not something you register or buy online: for housing, it is an animal that a licensed provider who knows you says helps with your disability, documented in a letter that meets your state's rules. Since HUD's 2026 change, that letter matters mostly under state law. We do not sell letters, refer anyone to letter sites, or offer qualification quizzes.
Who qualifies for an emotional support animal?
Where an ESA has legal weight, mostly housing, two things are needed: a disability, and a disability-related need for the animal. The Fair Housing Act defines the disability part:
"(1) a physical or mental impairment which substantially limits one or more of such person's major life activities, (2) a record of having such an impairment, or (3) being regarded as having such an impairment"42 U.S.C. 3602(h)
The still-posted 2004 HUD and DOJ Joint Statement describes the kind of information a housing provider may ask for when the disability or need is not obvious: information that verifies the disability, describes the accommodation, and "shows the relationship between the person's disability and the need for the requested accommodation." That link between your condition and the animal is what a clinician's letter is for.
Can I get an emotional support animal for anxiety or ADHD?
No law we found lists qualifying diagnoses, so the honest answer is: it depends on you, not on the label. Anxiety, depression, PTSD, ADHD or any other condition can meet the definition above if it substantially limits a major life activity, and it is your clinician who judges whether an animal helps with it. A website questionnaire cannot make that judgment, which is why we do not offer one. If your dog is trained to do a specific task for your condition, read psychiatric service dogs instead.
Who can write an ESA letter?
A licensed health care provider, and many states add conditions. These are the rules we verified:
| State | Who may write it | Relationship rule |
|---|---|---|
| California | A practitioner with a valid license, licensed where the documentation is provided; must do a clinical evaluation | At least 30 days |
| Florida | A health care practitioner or Florida telehealth provider; out-of-state practitioners only if they have seen you in person at least once | None stated |
| Iowa | A licensee in listed professions, or a similar out-of-state licensee in good standing | At least 30 days, in person or via telehealth |
| Montana | A mental health professional licensed in Montana, after a clinical evaluation | At least 30 days |
| Louisiana | A Louisiana license or a compact license; at least two sessions, in person or remote | At least 30 days |
| Arkansas | Licensed where the documentation is provided; dogs only; annual evaluation | At least 30 days |
| Virginia | Anyone with whom you have or had a therapeutic relationship | None stated |
| Tennessee | A health care provider with actual knowledge of your disability; websites selling certificates excluded | None stated |
| Wisconsin | A licensed health professional | None stated |
Other states' rules are on each state law page. What a legitimate letter usually covers is in the ESA letter template guide.
Can my therapist or primary care doctor write it?
Usually a therapist who has been treating you is the natural person to ask, and in most states we checked, a licensed therapist qualifies. A primary care doctor may qualify too, depending on the state. The details differ:
- Montana requires a mental health professional licensed in Montana, so a primary care doctor would not meet its rule.
- Florida accepts a health care practitioner as defined in its statutes, including telehealth providers as Florida law defines them.
- Virginia accepts anyone with a therapeutic relationship with you, and Tennessee a provider with actual knowledge of your disability.
- California requires the provider's license number and jurisdiction on the document, a 30-day relationship and a clinical evaluation.
Talking to your own clinician
This is an ordinary conversation, not a special appointment type. A few things make it easier:
- Explain the situation: for example, your building has a no-pets rule and your animal helps with specific symptoms.
- Ask whether they are comfortable documenting your disability and your need for the animal, and whether your state sets rules they need to follow (license, relationship length, evaluation).
- You do not need to share your full records with a landlord. The Joint Statement says "In most cases, an individual's medical records or detailed information about the nature of a person's disability is not necessary for this inquiry."
- If your clinician says an animal would not help, take that seriously and ask what would.
Online providers: what to check
Telehealth is legitimate in several states (Florida and Iowa say so outright, and Louisiana allows remote sessions), but a one-time questionnaire usually does not meet the rules above. Before you pay anyone online, check:
- Is the provider licensed in your state, and does your state require that?
- Will there be a real relationship for as long as your state requires (30 days in California, Iowa, Montana, Louisiana and Arkansas)?
- Is there an actual clinical evaluation, not a quiz?
- In Iowa, the finding must state whether the provider received a separate fee solely for writing it.
- Does the site bundle registrations, certificates or ID cards? Florida's statute says an internet registration "is not, by itself, sufficient information," and Tennessee excludes documents from websites whose main function is selling them.
HUD's 2026 memo names the online letter business as a problem, and attaches an April 2026 finding of no reasonable cause in a complaint "involving three emotional support animals supported by an online form letter." More in are online ESA letters legit?
One animal or several
None of the laws we reviewed sets a maximum number of ESAs. But each animal is part of the accommodation you are asking for, so the need for each one has to be supported. HUD's 2026 memo attaches a no-cause finding in a complaint involving three ESAs supported by an online form letter. If you need more than one animal, talk that through with your clinician, and check your state: Arkansas's law covers emotional support dogs only.
What the letter can and cannot do now
- Housing: it is the core of a reasonable accommodation request. Since HUD's May 22, 2026 memo, federal enforcement covers only trained animals, so outcomes for ESAs depend more on state law and, if needed, a private lawsuit. Colorado restored the old federal approach in state law in 2026. See ESA letters for housing.
- How long it lasts: it depends on the state. Iowa says a finding is valid "for a period of twelve months or the term of the rental agreement, whichever is greater."
- Flights: airlines may treat ESAs as pets; see can emotional support animals fly?
- Stores and restaurants: no effect. ESAs have no ADA public access.
- Registration: not needed and not helpful. See ESA registration.
Common questions
Can I get an ESA letter from my therapist?
Usually yes, if your therapist is licensed and meets your state's rules. Several states require a relationship of at least 30 days.
Can my primary care doctor write an ESA letter?
In many states a licensed health care provider can, but some states are stricter. Montana, for example, requires a mental health professional licensed in Montana.
Do I need to register my ESA?
No. No law requires it, and a registration is not what a landlord may rely on.
How many emotional support animals can you have?
The laws we reviewed set no number, but the need for each animal has to be supported by your clinician.
Can I get an ESA letter online?
Sometimes through a real telehealth relationship that meets your state's rules. A one-time questionnaire usually does not. We do not sell or refer letters.
Does an ESA letter let my dog come into stores?
No. ESAs have no ADA public access, whatever letter you have. See can emotional support animals go anywhere?
