What Is an Emotional Support Animal (ESA)? How to Qualify and Get an ESA Letter

Emotional support animals (ESAs) are companion animals that provide comfort and support to individuals living with mental health conditions. They are not the same as trained service animals; instead, they help by offering calming companionship that can ease symptoms like anxiety, depression, and stress. With interest in ESAs and the letters that certify them growing rapidly — search data show that queries about ESA letters have climbed to more than 100,000 searches per month【908348036268329†L340-L368】 — more people are exploring whether an ESA could be part of their mental wellness plan.

Why ESAs Are Gaining Attention

During the last few years there has been a surge in conversations about emotional support animals and the documentation that allows them to live in housing that might otherwise restrict pets. ESA letters protect clients’ rights under federal laws like the Fair Housing Act and, in some cases, allow ESAs to travel with their owners on airplanes【908348036268329†L340-L368】. As mental health awareness grows and telehealth makes care more accessible, more people are seeking these letters to ensure they can keep their animals close.

Who Qualifies for an ESA?

To legally designate a pet as an emotional support animal you need a letter from a licensed mental health professional stating that the animal alleviates symptoms of a mental health condition. ESAs can be recommended for a range of diagnoses, including anxiety disorders, depression, PTSD, and other conditions where companionship helps improve daily functioning. As a licensed marriage and family therapist in California, I evaluate clients to determine whether an ESA would meaningfully assist their therapeutic goals.

How to Obtain an ESA Letter

  1. Talk with a licensed therapist or doctor. If you believe an ESA could benefit you, start by discussing it during a therapy session or wellness appointment. Your clinician will assess your symptoms and determine if an animal is appropriate.
  2. Get a formal letter. A valid ESA letter should be written on professional letterhead, include your provider’s license number and contact information, and confirm that you have a condition that benefits from an ESA.
  3. Beware of scams. Many websites promise instant ESA letters without any clinical assessment. These letters are often invalid and can put you at risk. Make sure any evaluation involves a real clinician.
  4. Keep your letter current. ESA letters typically need to be renewed annually to remain valid for housing purposes.

Rights and Responsibilities

Under the Fair Housing Act, landlords must allow ESAs in housing that normally prohibits pets and cannot charge pet fees. However, ESAs do not have the same public‑access rights as service dogs, so businesses and airlines may have different policies. Owners are responsible for ensuring their animals are well-behaved and do not pose a danger or nuisance.
