An ESA letter in Colorado is an official document confirming the owner’s need for an emotional support animal and the animal’s ESA status. Colorado residents with ESAs are allowed in all housing situations, even if the property has a no pets policy. Landlords are obligated to ensure reasonable accommodation to ESAs under the Fair Housing Act (FHA). The Air Carrier Access Act (ACAA)* no longer classifies ESAs as service animals, and the option to travel on airplanes is at the discretion of the airline. Many airlines allow emotional support animals to travel with the owners with a valid ESA letter in Colorado, but they might be subject to fees.

Are Landlords Required to Accommodate ESAs of Tenants in Colorado?
Yes, landlords are required to accommodate ESAs of tenants in Colorado. ESAs in Colorado are considered assistance animals and are protected under the Fair Housing Act.

However, owners are held financially liable if the emotional support animal causes significant physical damage to the rental. Landlords are allowed to deny housing if the ESAs constitute a threat and are dangerous to other tenants.
Colorado enforces the FHA but protects landlords at the same time. Misrepresenting regular pets as ESAs to obtain better housing accommodation is considered a class 2 petty offense.

Yes, you can have multiple emotional support animals in Colorado. Federal and state ESA laws do not limit the number of ESAs.
Owners are permitted to have multiple ESAs if an LMHP confirms the purpose that each animal has in their owner’s care treatment plan. An ESA letter must be issued for each ESA.
The Fair Housing Act implies landlords must ensure reasonable accommodation for ESAs. A landlord is allowed to deny housing if the number of emotional support animals is unreasonable and causes undue financial burden or other logistical challenges.
The law does not define what is considered a reasonable number, but it is best to be practical – a dog and a cat are okay, but a landlord is likely to find it unreasonable if a person has three dogs, two cats, a bird, and a lizard.
Are ESA Laws the Same for All Cities in Colorado?
Yes, ESA laws are the same for all cities in Colorado. Colorado follows the federal Fair Housing Act. Under this law, landlords are required to make reasonable accommodations for ESA owners even in properties with no-pet policies at no additional cost.
Air travel is regulated by the Air Carrier Access Act (ACAA). Since the ACAA omits ESAs, airlines decide on their ESA policies independently. The FHA regulations apply to all cities in Colorado.
