To make your dog an emotional support animal (ESA), you need a letter from a licensed mental health professional stating that you have a diagnosed mental health condition and that your dog provides necessary emotional support as part of your treatment. There is no official registration, certification, or special training required. The letter itself is what gives your dog legal status as an ESA.
What an ESA Actually Is (and Isn’t)
An emotional support animal is not the same as a service animal. Under the Americans with Disabilities Act, a service animal is a dog individually trained to perform specific tasks for someone with a disability, like sensing an oncoming anxiety attack and taking a trained action to interrupt it. An ESA, by contrast, provides therapeutic benefit through companionship alone. It doesn’t need to perform any trained task. Because of this distinction, ESAs do not have the same public access rights as service animals. You cannot bring an ESA into restaurants, stores, or other public spaces where pets aren’t allowed.
The primary legal protection an ESA does carry is in housing, through the Fair Housing Act. That’s the protection most people are looking for when they search for how to get one.
Who Qualifies for an ESA
You qualify if you have a mental health condition recognized in the DSM-5, the standard diagnostic manual used by mental health professionals. Conditions that commonly qualify include anxiety disorders, depression, PTSD, bipolar disorder, ADHD, and schizophrenia. The key requirement is that a licensed professional determines your dog’s presence is a necessary part of your mental health care, not simply that you enjoy having a pet.
If you already see a therapist, psychiatrist, or counselor, this conversation can happen naturally during your existing care. If you don’t currently have a provider, you’ll need to establish that relationship first.
How to Get a Legitimate ESA Letter
The professionals authorized to write an ESA letter include psychiatrists, psychologists, licensed clinical social workers (LCSW), licensed professional counselors (LPC), and licensed marriage and family therapists (LMFT). Some primary care physicians can also write one, though most letters come from mental health providers. The provider must hold a valid, active license.
A legitimate ESA letter should include your provider’s license type, license number, the jurisdiction where they’re licensed, and the date the license became effective. It should state that you have a DSM-5 diagnosis for which the ESA is a necessary accommodation. Importantly, the letter should not include your specific diagnosis, only that you have one and that the animal is part of your treatment.
Some states have added specific requirements. California, for example, requires that a provider establish a client-provider relationship with you for at least 30 days before writing an ESA letter. The provider must also complete a clinical evaluation of your need for the animal. Other states may have similar rules, so check your state’s laws before starting the process.
Step by Step
- Talk to your mental health provider. If you’re already in treatment, ask about an ESA letter at your next appointment. Explain how your dog supports your mental health in practical terms.
- Get evaluated if you’re not in treatment. Schedule an appointment with a licensed therapist, psychologist, or psychiatrist. Be prepared to discuss your mental health history and how an ESA would help.
- Receive your letter. Once your provider agrees that an ESA is appropriate, they’ll write a letter on professional letterhead. This letter is typically valid for one year, after which your provider may need to reissue it.
- Submit the letter to your housing provider. Give a copy to your landlord or property manager as part of a reasonable accommodation request.
Avoiding ESA Scams
Dozens of websites sell “ESA registration,” “ESA certification,” or official-looking ID cards and certificates. None of these have any legal standing. There is no government registry for emotional support animals. HUD has made clear that certificates and registration cards are not legitimate documentation, and housing providers are within their rights to reject them.
HUD guidance also warns that documentation from an online source where the provider has no real relationship with the patient is not automatically considered reliable. A landlord can question a letter that came from a website where you filled out a questionnaire and paid a fee to someone you never spoke with. The safest path is a letter from a provider who genuinely knows you and your mental health needs.
Your Housing Rights With an ESA
The Fair Housing Act requires landlords and property managers to make reasonable accommodations for tenants with disabilities, and that includes allowing an emotional support animal even in housing that normally prohibits pets. Your landlord also cannot charge you a pet deposit, pet fee, or pet rent for an ESA. You may still be held financially responsible for any property damage your dog causes, but the upfront fees must be waived.
A landlord can legally deny an ESA request only under limited circumstances: if the specific animal poses a direct threat to the health or safety of others, if the animal would cause significant physical damage that no other accommodation could prevent, or if the accommodation would create an undue financial or administrative burden on the housing provider. A blanket “no pets” policy is not grounds for denial when you have a valid ESA letter.
If your disability and need for the animal are not obvious, your housing provider is allowed to request documentation. That’s where your ESA letter comes in. They can ask for reliable evidence that you have a disability-related need for the animal, but they cannot ask for your specific diagnosis or detailed medical records.
ESAs and Air Travel
This is where the rules have changed significantly. In 2021, the U.S. Department of Transportation finalized a rule that allows airlines to treat emotional support animals as pets rather than service animals. Previously, airlines were required to accommodate ESAs in the cabin at no charge. That is no longer the case. Under current rules, only trained psychiatric service dogs (and other task-trained service dogs) qualify for in-cabin accommodation on flights.
Individual airlines may still choose to allow ESAs without charge at their discretion, but they’re not required to. If you’re flying with your dog, check your airline’s current pet policy. In most cases, you’ll need to pay the standard pet fee and follow the airline’s carrier and size requirements.
Your Dog Doesn’t Need Special Training
Unlike service animals, ESAs have no training requirement under federal law. Your dog doesn’t need to pass any test or learn specific tasks. That said, your dog does need to behave well enough that it doesn’t create problems in your housing situation. A dog that barks excessively, behaves aggressively toward neighbors, or causes significant property damage could give your landlord legal grounds to revoke the accommodation.
Basic obedience, housetraining, and the ability to be calm in shared spaces go a long way toward protecting your ESA status. While no formal certification exists, investing in basic training makes the arrangement work for everyone involved, including your dog.
