If you believe that an ESA is right for you and would like help from a healthcare professional licensed for Colorado, complete the questionnaire in the link below to get started with the process.

ESA vs. Service Animal

Pets provide unconditional love, support, and friendship to their owners. An emotional support animal serves a similar purpose but is recommended by a healthcare professional to assist someone with a mental illness or emotional wellness issues.
For example, an emotional support animal may be used by someone who has chronic depression, anxiety, PTSD, or a phobia. Sometimes people confuse ESAs with service dogs, but there are several differences.
A service animal can only be a dog and must be specifically trained to perform a task for a disabled individual. This can include several skills like guiding, alerting, opening doors, or pulling a wheelchair. ESAs, on the other hand, do not require any specialized training. They help their owners just by being present. ESAs can also be different animals like cats, dogs, rabbits, fish, turtles, birds, and rodents.
Colorado Emotional Support Animal Registration
Are you looking to register your dog or cat as an emotional support animal? Stop! Registering your pet on a website will not make your pet an ESA, and you will not be protected under the Fair Housing Act. Registration of emotional support animals in Colorado is not recognized by the law and will not be accepted by landlords.

Many landlords are not aware of ESA laws in Colorado. They may have heard something on Facebook or from a friend and request documentation that is simply unnecessary. ESA registration from a website does not legally protect you and does not qualify your animal as a legitimate emotional support animal.
No, all you need is documentation from a licensed healthcare professional. Read more about how to get an ESA in Colorado and about ESA letters in the next section.

How to Get an Emotional Support Animal in Colorado

To make your animal a legit emotional support animal, you will need an ESA letter from a licensed healthcare professional. An ESA letter is the only legal document that is required for emotional support animals in Colorado. You can talk to your existing health professional or connect with one online. Your medical health professional must determine that you will benefit from an ESA and write a letter on their official letterhead to qualify your animal as an ESA.

The ESA Letter
There is specific information that must be included in your ESA letter:
- It must be written on your health professional’s letterhead
- It includes their name, license number, date of issue, and state it was issued
- It contains the licensed medical health professional’s signature
You can obtain an ESA letter through an in-person visit or an online therapist. If you do not have access to a licensed health professional, you can connect with a professional online.

Where Can I Take My ESA in Colorado?
“No Pets” Policy Housing – According to the Fair Housing Act, a landlord cannot legally evict you or deny you access to a rental unit just because of your emotional support animal. In fact, the landlord must make “reasonable accommodation” for your assistance animal (meaning they cannot charge you additional fees and must welcome the animal as long as it’s not causing an undue financial burden on the landlord and the animal is not a threat to the other tenants or property). Emotional support animals are also exempt from breed and size restrictions when it comes to housing.
In Cabin Flights – Unfortunately, ESAs are no longer allowed on flights. Psychiatric service dogs, however, are still allowed to board the cabin of planes free of charge. PSDs help with mental health issues like ESAs, but they are trained to perform a task relating to their owner’s condition.
Employment Rights – Employers in Colorado cannot discriminate against people with mental health disabilities. Businesses with five or more staff must ensure that a service animal can accompany the employee to work. Unfortunately, emotional support animals do not have access rights in the office. If your employer’s usual guidelines state that animals are not allowed in the office, talk to your HR representative about whether there are exceptions for assistance animals like ESAs.

QUESTION: I recently relocated from Nevada and have a capuchin as my support animal. Will i be allowed to bring him to Colorado as my support animal? From what I understand they are not allowed in the state as pets.
Unfortunately no. Under HUD guidelines ESAs must be small, domesticated animals typically kept in the home. An animal that is banned in a state as a pet would likely not qualify.
QUESTION: I was told that under Colorado law your ESA has to remain with you at all times, is this true?
We’re not aware of any such requirement – ESA owners (and really most pet owners) have to leave their animals at home at times to run errands, work jobs, go to school, etc. ESAs are not allowed in public places so it would be unreasonable to expect an owner to stay attached to their ESA at all times.
I have a heart condition that causes severe palpitations when I get anxious. I noticed my dog can sense them and petting her calms me down; taking the palpitations away. Do technically fall under needing a service dog if it is a physical and mental issue?

Can you be separated from your ESA if taken to jail in Colorado?
There is no law we are aware of that would allow an ESA owner to take their animal to jail.
My apartment is trying to fine me an unauthorized pet fee due to not providing them with an ESA form even though my pet qualifies and has been documented as an ESA. We bought my pet home yesterday did not notify them and planned on telling them today as well as providing them with the form that he was an ESA as of today. Also they are trying to charge us for a pet waste DNA test kit due to other tenants not picking up their pet waste by law are they able to do either of these? They are claiming all other fees and deposits will be waived except for these two. I appreciate any and all suggestions on this.
