The state of Colorado is one of the most stringent states concerning the laws regarding emotional support animals (ESA). Along with the existing Fair Housing Act at the federal level, the state enacted House Bill 21-1271 in 2021, resulting in some of the most stringent documentation requirements and anti-fraud laws in the nation. In case you are living in Colorado and use the ESA, this article will help you understand what is required of you according to the law, what your landlord should and should not do, and how to obtain an effective letter.
2026 federal update. On May 22, 2026, HUD restricted enforcement of the federal Fair Housing Act concerning untrained emotional support animals. It is an update made at the federal level – Colorado maintains its own state law protecting ESAs in housing, which means that your state-level rights are unaffected by this change. Enforcement may continue to evolve, and it might be worth checking the latest guidelines with your state’s fair-housing agency or with an attorney.
Colorado ESA Laws – What You Need to Know
Although Colorado is considered one of the most ESA-friendly states, this friendliness is accompanied by the responsibility that should be undertaken. In addition to the FHA, the Colorado House Bill 21-1271 has introduced further protection of housing rights for ESA owners and has established requirements for documentation, as well as the fraud penalty for those who lie about their pets being ESAs. Another state law related to ESAs is the Colorado Anti-Discrimination Act (CRS § 24-34-501 et seq.).
Federal Fair Housing Act (FHA) Protections
In accordance with the provisions of the FHA (42 U.S.C. §3601–3619) and HUD, Colorado landlords must typically:
- Exclude no-pets policies, breeding restrictions, and size limitations for an ESA that is verified.
- Refrain from levying any pet rental fee or pet security deposit on a bona fide ESA.
- Extend such accommodation to most forms of residential properties, barring a few exceptions.
- Seek credible documentation for the disability and the need for the animal in question.
Colorado-Specific ESA Laws – HB 21-1271
As of August 2021, HB 21-1271 is one of the most comprehensive ESA state laws in the United States. Some of the main provisions of the law are:
- The existence of a provider relationship is necessary. A valid ESA letter must be issued by a licensed health care provider with whom the person has an established therapeutic relationship, rather than a provider whose sole communication with the patient is issuing an ESA letter.
- Online-only letter mills are prohibited. If health care providers issue ESA letters based on the information received through a questionnaire only without a clinical relationship with the patient, they may face disciplinary action.
- The landlord can ask for documentation, but nothing more. Landlords can request documentation, but are not entitled to obtain information regarding the nature of the tenant’s disability.
- ESA misrepresentation is a deception. Deliberate deception regarding the ESA status of your pet is considered a violation of the Colorado Consumer Protection Act.
- The health care provider may also face disciplinary action. Health care providers issuing a fraudulent ESA letter can be subject to disciplinary action.
Colorado Anti-Discrimination Act (CADA)
CADA prohibits housing discrimination based on disability, and CCRD investigates complaints about housing discrimination due to disability as well as ESA accommodations. It complements the federal FHA but does not supersede it.
ESA Letter Requirements in Colorado
Colorado’s laws demand more than just the federal law:
- The letter should be written by a licensed health care professional – psychologist, psychiatrist, LCSW, LPC, LMFT, physician, or any other such professional
- According to Colorado law, the health care provider should have met the client at least once, either in person or through telemedicine, and have a therapeutic relationship – a single-letter-only contact will not do
- The letter should state the specific disability covered by the FHA and mention how the ESA provides relief from the symptoms
- The letter should contain the name of the licensed health care provider, his or her license number, license type, state of licensure, date, and signature on letterhead
- A letter written by the services providing the questionnaires only, without an actual evaluation process, may not meet the criteria of landlords and will be considered illegal
As the Colorado law specifically demands a bona fide relationship with the health care provider, the use of the ESA Clinic, which provides an evaluation process by licensed professionals, will help you get your letter to meet all the standards.
Housing Rights and Landlord Obligations
Landlords in Colorado have to adhere to both the FHA and HB 21-1271:
- Must allow ESAs in pet-free buildings based on legitimate documentation
- Cannot impose any fee for ESA, such as pet fees, breed fees, or pet deposits
- May ask for documentation, but cannot ask for specific diagnosis information
- May confirm if the license of the ESA prescriber is valid and up-to-date
- May reject a certain animal because of a specific danger it poses
- Cannot punish a tenant for requesting an ESA, as per both state and federal law
ESA Fraud and Penalties in Colorado
There are severe ramifications if a person engages in misrepresentation as per HB 21-1271:
- Tenant fraud – It is considered deceptive trade practices according to the Colorado Consumer Protection Act when a tenant makes any false representations about their animal as being an ESA
- Provider fraud – Any licensed provider issuing letters of ESAs that have no clinical justification can be disciplined and possibly even have his/her license suspended or revoked
- Civil penalties – There can be civil penalties associated with the misrepresentation
ESA vs. Service Animals in Colorado
- Service animals are individually trained to assist with certain tasks and have access rights under the ADA
- Emotional support animals offer comfort by being there and do not require task training; they are covered under the FHA for housing only
- The bill, HB 21-1271, is relevant specifically to assistance animals for housing situations only
Air Travel With ESAs From Colorado
As per the DOT’s change in regulation of the Air Carrier Access Act from January 2021, ESAs can no longer be considered as pets that must be allowed on board airplanes; only those that have undergone training for a particular disability can now be considered as pets that must be allowed on board. Airlines operating from Denver International Airport or Colorado Springs Airport may allow ESAs under their pet policies.
How to Get an ESA Letter in Colorado
- Build a connection with a licensed professional – the Colorado law mandates a legitimate therapeutic relationship, which means having a valid clinical interaction (either in-person or by telemedicine).
- Undergo a complete assessment of your psychological condition and ways that the ESA will help you in your treatment.
- Get a legitimate ESA letter that is compliant with the standards of FHA, and also follows the provisions of Colorado HB 21-1271.
- Deliver the ESA letter and make a reasonable accommodation request in writing to your landlord.
Selecting the proper service provider is critical in Colorado more than in any other state. ESA Clinic helps you establish a valid relationship with the licensed professional who will give you a genuine ESA assessment.

Frequently Asked Questions
Does HB 21-1271 make it harder to get an ESA letter in Colorado?
It doesn’t make it harder – it makes it more legal. All the law states is that the person needs a relationship with a licensed professional, not a one-time online questionnaire; the letter is legal to use should a landlord ever question it.
Can a Colorado landlord charge pet rent for my ESA?
No. With proper ESA documentation, any landlord should waive the pet rent, pet deposit, or breed fee since your ESA will be considered an accommodation rather than a pet.
Can my provider issue an ESA letter after a single online questionnaire?
No. Under the Colorado laws, one cannot get an ESA letter without first establishing a therapeutic relationship with the mental health professional involved, which involves at least one session, in-person or telehealth visit.
What happens if I misrepresent my pet as an ESA in Colorado?
This is considered a deceptive trade practice under the Colorado Consumer Protection Act that can lead to civil penalties and liability for damages arising from the misrepresentation.
Can I bring my ESA into stores or restaurants in Colorado?
No, since ESAs do not have the right of public accommodation in Colorado. Only trained service animals are covered by the ADA for protection in public settings, while ESAs have protection in the housing sector only.
Do airlines have to accept my ESA for free in Colorado?
No, due to the change in the DOT regulation in 2021, airlines are not required to waive the fee for ESAs. Most airlines consider them to be regular pets.
