How to Get a Doctor’s Note for an Emotional Support Animal

To get a doctor’s note for an emotional support animal, you need a real clinical evaluation with a healthcare professional licensed in your state, followed by a dated letter on their letterhead confirming that you have a disability and that the animal provides therapeutic benefit. There is no government form, no national registry, and no shortcut that reliably holds up with landlords. What matters is that the provider has personal knowledge of your condition and is willing to document it in writing.¹

What the Letter Has to Establish

A valid ESA letter documents two things: that you have a disability that substantially limits a major life activity, and that an emotional support animal alleviates symptoms of that condition. It does not have to name your specific diagnosis. Some landlords ask for one, but you’re not obligated to disclose it.

HUD has been clear that documentation doesn’t have to follow a specific format.¹ The substance is what counts. A letter from a provider who genuinely knows your condition will do more for you than any template.

Who Can Write It

HUD describes the gold standard as “a note from a person’s health care professional that confirms a person’s disability and related need for an assistance animal for therapeutic purposes when the health care professional has personal knowledge of the individual.”¹ That’s broader than most people expect. Your primary care physician can write it if they’ve been treating you for a qualifying condition. Letters from mental health professionals who specialize in the conditions ESAs address tend to carry the most weight, and psychiatrists, psychologists, licensed clinical social workers, and licensed professional counselors are the common sources.

The provider must be licensed in the state where you live. This is where telehealth trips people up. A remote evaluation from a properly licensed in-state provider can produce a valid letter. A quick call with someone licensed in a different state likely won’t, and a growing number of states now explicitly require that the evaluating clinician hold an active license in the tenant’s state.

If you’re already seeing a therapist or psychiatrist who knows your history, ask them first. That’s the shortest and most credible route.

What the Evaluation Involves

A legitimate evaluation is a real clinical conversation. Expect questions about your mental health history, current symptoms, treatments you’ve tried, and how the animal’s presence affects your daily functioning. Sessions typically run 30 to 60 minutes, though length varies by provider.

The clinician is deciding two things: whether you meet the criteria for a qualifying disability and whether an emotional support animal has a therapeutic connection to that disability. A provider who is willing to write a letter for anyone who asks, without a genuine assessment, is precisely the kind of source HUD warns against.

Cost varies with the provider, your insurance, and your location. Insurance may cover the evaluation itself when it’s part of ongoing mental health care, even if the letter is not separately billable.

Avoiding Online Letter Mills

HUD has taken a direct position on the websites that sell ESA letters based on a short questionnaire and a credit card payment. In its guidance, HUD states that documentation from these sites “is not sufficient to reliably establish that an individual has a non-observable disability or disability-related need for an assistance animal” and calls such certificates “not meaningful and a waste of money.”¹

Signs that a service isn’t legitimate:

Instant approval with no real evaluation
Providers who never ask about your mental health history
Offers to “register” or “certify” your animal, or to sell you an ID card
Providers not licensed in your state

There is no national ESA registry. Any site selling registration numbers is selling something with no legal standing. Several states now classify knowingly misrepresenting a pet as a protected assistance animal as a misdemeanor, with penalties including fines and community service.

What the Letter Should Include

No format is legally required, but certain elements make a letter far more useful when a landlord reviews it:

The professional’s name, license type, license number, and licensing state
A phone number or address where the provider can be reached for verification
Confirmation that you have a disability that substantially limits a major life activity, without necessarily naming the diagnosis
A statement that the emotional support animal is necessary for your mental health or alleviates symptoms of your disability
The date of issuance

Provider letterhead adds credibility, though it isn’t a legal requirement. Keep the original in a safe place and provide copies with accommodation requests.

Giving the Letter to Your Landlord

The Fair Housing Act requires landlords to make reasonable accommodations for people with disabilities, and waiving a no-pet policy for an assistance animal is one of the most common examples.²³

Submit a written reasonable accommodation request to your landlord or property manager. State that you have a disability under the Fair Housing Act, that you need an assistance animal as an accommodation, and briefly describe how the animal helps you. Attach a copy of your letter and ask for a written response. Ten business days is a reasonable timeframe to expect a reply.

A landlord cannot charge a pet deposit, pet fee, or monthly pet rent for an emotional support animal. HUD’s guidance explicitly lists waiving pet deposits and fees as an example of a reasonable accommodation.² You can still be held liable for any damage the animal actually causes, but upfront charges based on having the animal are not permitted.

Landlords have limited grounds to deny a request. Under HUD’s guidance, they can refuse if the specific animal poses a direct threat to health or safety that can’t be reduced through other accommodations, if the animal would cause significant property damage that can’t be mitigated, or if granting the request would impose an undue financial and administrative burden.² Breed restrictions, weight limits, or a general preference against animals are not valid grounds. The concern has to be specific to your animal and supported by evidence.

How Often to Renew

Federal law does not set an expiration date for ESA letters. In practice, most landlords expect a letter dated within the past 12 months, and property managers commonly ask for an updated letter when you move or renew a lease. If you keep an ongoing relationship with your provider, refreshing the letter is usually quick. If you no longer see the original provider, you’ll need to establish care with a new one and go through another evaluation.

Where an ESA Letter Doesn’t Help

Two situations people often assume the letter covers, and it doesn’t.

Airlines are no longer required to treat emotional support animals as service animals. A Department of Transportation rule that took effect on January 11, 2021, redefined “service animal” under the Air Carrier Access Act to include only dogs individually trained to perform tasks for a person with a disability, and the rule states that carriers “are not required to recognize emotional support animals as service animals and may treat them as pets.”⁴ Your ESA now falls under each airline’s pet policy, including size limits, carrier requirements, and fees.

Workplaces operate under different rules than housing. The ADA’s employment provisions don’t define “service animal” the way its public-accommodations titles do, and neither the ADA nor EEOC guidance specifically addresses emotional support animals as workplace accommodations. Requesting an ESA at work goes through the ADA’s interactive process with your employer’s HR department, and documentation that specifically addresses how the animal supports your ability to perform essential job functions strengthens the request. Employers can consider factors like coworker allergies, safety, and the nature of the workplace.
