Emotional support animals (ESAs) provide companionship and comfort to individuals managing mental or emotional health conditions. Unlike service animals, they don’t perform specific trained tasks — but for many people, having an ESA is a medically recognized part of their treatment. This guide covers what ESAs are, how to get one, and what legal rights apply to you.
What Is an Emotional Support Animal?
An emotional support animal is a pet prescribed by a licensed mental health professional (LMHP) — such as a therapist, psychologist, or psychiatrist — as part of a treatment plan for a recognized mental or emotional health condition. Common qualifying conditions include depression, anxiety, PTSD, bipolar disorder, and panic disorders, as assessed against the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
ESAs are not limited to dogs. Virtually any domesticated animal can serve as an emotional support animal, including cats, rabbits, and birds. ESAs do not require specialized training and do not have the same public access rights as trained service animals. However, they are entitled to specific legal protections under federal housing law. The primary benefit of ESA status is that it allows owners to keep their animal in housing that otherwise prohibits pets.
ESAs vs Service Animals
The key distinction between an emotional support animal and a service animal lies in training and legal access rights. Service animals — as defined by the Americans with Disabilities Act (ADA) — are dogs (or miniature horses) trained to perform specific tasks directly related to a person’s disability. Examples include guiding someone with visual impairment, alerting a person with hearing loss, reminding someone to take medication, or calming a person with PTSD during an anxiety attack.
Because service animals perform trained tasks, they are granted broad legal access: they may accompany their handler into all public spaces, including restaurants, hotels, public transit, and workplaces, regardless of pet policies. Emotional support animals do not have the same broad access rights. Their legal protections are primarily limited to housing under the Fair Housing Act. Understanding this distinction is essential for ESA owners who want to know what to expect in different situations.
How to Get an ESA Letter
The only legitimate way to obtain an ESA is through a consultation with a licensed mental health professional. The LMHP evaluates your mental health condition and, if appropriate, issues an ESA letter — an official document stating that you have a diagnosed condition and that an emotional support animal is part of your treatment.
This letter is the legal basis for ESA housing accommodations. It should be written on the LMHP’s letterhead, include their license number and state of licensure, and be signed and dated. Be wary of websites that sell “ESA registration” or “ESA certification” — there is no official national registry for emotional support animals, and these services have no legal standing. Registration vests, ID cards, and certificates sold by third-party businesses do not confer any legal rights.
Nearly any animal you already own can become your ESA with the appropriate letter from a qualified professional. The animal should be non-aggressive and manageable in a home environment.
Housing Rights Under the Fair Housing Act
The Fair Housing Act (FHA) is the primary federal law protecting ESA owners. Under the FHA, housing providers — including landlords and housing associations — must provide reasonable accommodations to individuals with disabilities who require assistance animals, even if the property has a no-pets policy. This means a landlord generally cannot refuse to allow an ESA in a rental unit based on a no-pet rule.
The FHA also prohibits housing providers from charging pet deposits or additional fees specifically because of an ESA, since ESAs are treated as necessary accommodations rather than optional pets. However, the tenant remains responsible for any damage the animal causes.
To request accommodation, you provide your housing provider with your ESA letter. The provider may request additional reliable information if your disability is not apparent. A request can only be denied if approving it would impose an undue financial burden on the provider or if the specific animal poses a direct threat to the health or safety of others. In January 2020, the U.S. Department of Housing and Urban Development issued updated guidance to help housing providers evaluate ESA accommodation requests and distinguish legitimate requests from attempts to circumvent pet policies.
Air Travel and ESA Policies
Air travel rules for ESAs changed significantly in early 2021. Under the Air Carrier Access Act (ACAA), the U.S. Department of Transportation revised its rules, allowing airlines to treat emotional support animals as pets rather than service animals. As a result, most major U.S. airlines no longer allow ESAs to fly free in the cabin — they must be transported as regular pets, which typically means a fee and may require a carrier that fits under the seat.
Psychiatric service dogs — dogs specifically trained to perform tasks for individuals with psychiatric disabilities — retain broader protections and are generally still permitted in aircraft cabins. Some international airlines may have different policies, so it is essential to check with your specific carrier before booking if you plan to travel with an emotional support animal. Requirements and fees vary by airline and route.
Psychiatric Service Dogs
Psychiatric service dogs occupy a different legal category from ESAs. They are trained to perform specific tasks that mitigate the effects of a psychiatric disability — for example, grounding techniques during a panic attack, creating physical space for individuals with social anxiety, interrupting self-harmful behaviors, or medication reminders. Because they perform trained disability-related tasks, they qualify as service animals under the ADA.
This means psychiatric service dogs have the same full public access rights as other service animals: they may accompany their handler in restaurants, hotels, workplaces, public transportation, and other spaces regardless of pet policies. Under the Fair Housing Act, landlords must also accommodate psychiatric service dogs in housing. A psychiatric service dog requires more preparation than an ESA — including identifying and working with a trainer to develop the relevant task behaviors — but provides significantly broader legal protections.
