  • Your letter needs to be written by a licensed professional in the state where you reside
  • An online professional can provide an ESA letter that works just as well as one from a therapist seen in person
  • In 2021, the US Department of Transportation (DOT) changed the rules that previously required airlines to let ESA animals in a plan’s cabin.

US Service Animals Customer Reviews


5/5  US Service Animals
By far the best out of all the options you have provided. I have actually audited each company in this industry and US Service Animals is the only one that I found to have actual lawyers working with them. In fact, one of the owners is a lawyer. Their legal dept is top notch and actually helps people with HUD issues. I’ve been thorough with every company and actually have upcoming litigation with some of the sites on your list because of the illegal practices of their mental health professionals on staff and how they operate. Most of the companies on your list operate in the gray space between legal and illegal… not good. You should do a better job of vetting these companies before you recommend them.

Difference between ESA and PSD Letters


A bit of background: up until 2021, an ESA (Emotional Support Animal) was permitted to both live in residential properties that restricted pets and to fly with their owner in the cabin of airplanes. However, earlier this year, the US Department of Transportation (DOT) changed the rules concerning the flying of support animals in airplanes. This was primarily due to airlines complaining about the increase in the number of support animals on domestic flights and anecdotes of passengers and flight attendants getting bitten by unruly animals. As a consequence, airlines are now allowed to permit only a trained Psychiatric Service Dog (PSD) in the flight cabin. Unlike an ESA animal, a PSD dog must be appropriately trained to perform functions unique to their role. There are several options for training, but the most common method is from a professional dog trainer who can meet two goals: 1) The General Public Access Test, which ensures that a dog behaves appropriately in public settings; and 2) Specialized Work Training, which satisfies that the dog is able to perform specific actions related to their owner’s disability.

Thus, the difference between ESA and PSD is that a PSD must be a dog that is specially trained to behave appropriately and perform tasks related to the owners disability. By contrast, a ESA may be any domesticated animal (dog, cat, rabbit, etc.), that does not have any specialized training, but its mere presence provides comfort for their owner during a time of need.

It should be noted that the DOT rule change did not affect the ability of an ESA animal to live in a residential property that restricts pets.

Also, while the DOT rule change now allows airlines to permit only PSD dogs in cabins, some airlines still allow ESA animals in cabins. It is up to the discretion of the airlines. As of July of 2021, there are three smaller airlines still ESA-friendly: LatAm Airlines, Volaris and WestJet. However, this can change at any time, so please contact the airline before you buy a ticket to confirm the policy.

Free (or very cheap) ESA Letter Options


While none of the above online ESA providers offer a free ESA letter option, there is still a way you may be able to get a letter for free. If you are already seeing a licensed mental health professional, you can simply ask your doctor or therapist to provide a letter explaining your situation on their official letterhead. Most professionals will do this for no charge or for a minimal fee.

If your therapist has not drafted an ESA letter before, below is a template that you can provide to them:



To Whom It May Concern:

[Full Name of Patient] is my patient and has been under my care since [Date]. I am familiar with their condition, and they have a recognized emotional disability under The Fair Housing Act, and the Americans with Disabilities Act. Due to this disability, [Patient Name] experiences symptoms which substantially inhibits their normal and significant day to day activities.

As a result, I have prescribed them an emotional support animal that will assist in coping with their disability. The presence of this animal is necessary for [Patients Name] and the improvement of the symptoms of their condition. The animal accompanying them in the property is also necessary for [Patient Name] to improve their quality of life and ability to live independently.

I am familiar with the professional literature concerning assistive and/or therapeutic benefits of assistance animals for people with disabilities. Upon request, I will be happy to answer questions you may have concerning my recommendation that [Patient Name]  have a therapy animal.

ESA Letter FAQs

  • How long does an ESA letter last?

One year following the day they are issued from the healthcare professional. So you will need to renew your ESA letter every year. Most online providers give a discount for letters for subsequent years.

  • Can my landlord charge a pet/security deposit for my ESA animal?

No. Based on statements from HUD, most disability law experts believe that requiring a deposit would be illegal. However, the landlord could recoup reasonable costs for damage done after the fact by the ESA animal.

  • Can I bring my ESA animal to university or on-campus housing?

Yes. Even though most colleges previously had a no pets rule for housing, a couple of court cases were litigated where colleges ended up being required to make reasonable accommodations for disabled students under the Fair Housing Act. Now most colleges and universities have adopted polices for the use of assistance animals in housing.
