Colorado ESA Laws & Tenant Rights
Under the federal Fair Housing Act and Colorado's own Anti-Discrimination Act (CADA), tenants with a valid ESA letter have powerful legal protections. Here is everything you need to know.
The Laws That Protect Colorado ESA Owners
Two key laws work together to give Colorado tenants with ESAs strong housing protections.
Fair Housing Act (FHA) — Federal
The FHA (42 U.S.C. § 3604) requires landlords to make reasonable accommodations for tenants with disabilities — including allowing ESAs in no-pet housing. It applies to virtually all housing in Colorado, including apartments, condos, HOA communities, and most private rentals.
- No pet fees or pet deposits for ESAs
- No breed or weight restrictions for ESAs
- Must allow ESAs in no-pet buildings
- Cannot ask for your diagnosis or medical records
Colorado Anti-Discrimination Act (CADA)
CADA (C.R.S. § 24-34-502) reinforces and in some respects expands FHA protections at the state level. CADA covers housing accommodations in Colorado and is enforced by the Colorado Civil Rights Division (CCRD). Violations can result in fines and mandatory remediation.
- Applies to all Colorado landlords (even small private landlords)
- ESA letters from licensed Colorado clinicians are valid documentation
- Landlords have 10 days to respond to an accommodation request
- CCRD can investigate complaints and impose fines
What Colorado Landlords Can & Cannot Do
Understanding the boundaries of landlord authority is the first step to protecting your rights.
Landlords CANNOT:
- Charge pet fees, pet rent, or pet deposits for your ESA
- Enforce breed restrictions, weight limits, or size bans on ESAs
- Refuse to allow your ESA in a no-pet building
- Ask for your specific diagnosis, medical history, or treatment details
- Require you to use a specific therapist or provider
- Deny your request without providing a written reason
- Retaliate against you for requesting an ESA accommodation
Landlords CAN:
- Request a valid ESA letter from a licensed mental health professional
- Verify the letter was signed by a Colorado-licensed clinician
- Deny an ESA that poses a direct, documented threat to others
- Deny an ESA that causes substantial physical damage to the property
- Ask for a new letter if your current one is more than 12 months old
- Require the ESA letter to be on official clinician letterhead
- Take reasonable time (up to 10 days) to review your request
How to Request an ESA Accommodation in Colorado
Follow these steps to formally request a reasonable accommodation from your Colorado landlord.
Get a Valid ESA Letter
Obtain a signed ESA letter from a Colorado state-licensed mental health professional (LCSW, LPC, psychologist, or psychiatrist). The letter must be on official letterhead and include the clinician's license number and state of licensure.
Start Free ScreeningSubmit a Written Accommodation Request
Write a simple letter to your landlord or property manager stating that you have a disability-related need for an ESA and requesting a reasonable accommodation under the FHA. Attach your ESA letter. Keep a dated copy for yourself.
Wait for a Response (Up to 10 Days)
Under Colorado law, landlords must respond within a reasonable time — typically 10 business days. If they request additional information, respond promptly. They cannot ask for your diagnosis.
If Denied — File a Complaint
If your landlord denies your request without a valid legal reason, you can file a complaint with HUD (hud.gov/program_offices/fair_housing) or the Colorado Civil Rights Division (ccrd.colorado.gov). You may also have a private right of action.
Know Your Denial RightsWhat Mental Health Conditions Qualify?
Under the FHA, a disability is a physical or mental impairment that substantially limits one or more major life activities. Many common mental health conditions qualify.
Important: You do not need a formal diagnosis label — you need a licensed clinician to assess that your mental health condition qualifies as a disability and that the ESA provides therapeutic benefit. Our Colorado clinicians make this determination during your evaluation.
Colorado ESA Law — Frequently Asked Questions
State-specific answers for Colorado tenants.
Does Colorado have its own ESA law beyond the FHA?
Yes. The Colorado Anti-Discrimination Act (CADA, C.R.S. § 24-34-502) provides additional state-level protections. The Colorado Civil Rights Division (CCRD) enforces CADA and can investigate housing discrimination complaints, which is faster than waiting for a HUD investigation.
Can my Colorado HOA deny my ESA?
No. HOAs are subject to the FHA just like landlords. They cannot ban ESAs through pet restrictions in their covenants or bylaws. You must still submit a written accommodation request with a valid ESA letter.
Do Colorado condos and co-ops have to allow ESAs?
Yes. Both condominiums and housing cooperatives are covered by the FHA in Colorado. The only exception is owner-occupied buildings with 4 or fewer units where the owner does not use a real estate broker or agent.
Does my ESA letter need to come from a Colorado therapist?
HUD guidance requires the letter to be from a licensed mental health professional. While the law doesn't explicitly require a Colorado license, Colorado landlords and the CCRD look favorably on letters from Colorado state-licensed clinicians — and some landlords specifically request this.
Can my landlord demand my therapy records?
No. Under the FHA and CADA, landlords may only request reliable documentation that you have a disability and that the ESA is related to that disability. They may NOT demand therapy notes, medical records, or your specific diagnosis.
How long is an ESA letter valid in Colorado?
ESA letters do not have a legally mandated expiration date, but HUD guidance allows landlords to request updated documentation. In practice, most Colorado landlords and housing providers consider a letter valid for 12 months. We recommend renewing annually.
