Can My Colorado Landlord Deny My ESA?
The short answer: rarely, and only for specific legal reasons. Here is exactly what Colorado law says — and what to do if your landlord denies your ESA illegally.
ILLEGAL Denial Reasons (Landlord Cannot Use)
- "We have a no-pets policy" — ESAs are not pets under the FHA
- "Your dog is the wrong breed or too heavy"
- "We don't allow animals over 25 lbs"
- "You need to pay a pet deposit first"
- "We need your therapy records or diagnosis"
- "Online ESA letters aren't valid"
- "We've never allowed ESAs before"
- "Other tenants might be allergic"
LEGAL Denial Reasons (Narrow Exceptions)
- The ESA poses a direct, documented threat to the health or safety of others (must be specific, not speculative)
- The ESA would cause substantial physical damage to the property that cannot be mitigated
- The letter was fraudulent or issued by an unlicensed provider
- The building is owner-occupied with 4 or fewer units AND the owner doesn't use a broker
- Single-family home sold or rented without a broker (rare exemption)
Important: Even when a landlord believes one of the legal exceptions applies, they must provide a written reason and engage in an interactive process with you before denying. A blanket denial without any explanation is itself a violation.
What to Do If Your Landlord Denies Your ESA
Don't panic — you have legal options. Follow these steps in order.
Get the Denial in Writing
If your landlord verbally denied your ESA, ask them to put the reason in writing. This creates a paper trail. Send them a follow-up email summarizing the verbal denial ("Just following up on our conversation — my understanding is you denied my ESA accommodation request because...").
Review the Denial Reason
Compare the stated reason to the legal exceptions above. In most cases, landlord denials do not meet the legal threshold. Common invalid reasons include citing a no-pets policy, requesting pet deposits, or claiming the online letter is not valid.
Respond in Writing with the Law
Often Resolves the IssueSend your landlord a written response citing the Fair Housing Act (42 U.S.C. § 3604) and the Colorado Anti-Discrimination Act (C.R.S. § 24-34-502). Reference HUD's 2020 guidance on ESA documentation. Often a firm, informed response resolves the issue.
File a CCRD Complaint
Free to FileIf the landlord still refuses, file a complaint with the Colorado Civil Rights Division (ccrd.colorado.gov). CCRD will investigate and can impose fines. You can also file with HUD at hud.gov/fairhousing. There is no fee to file a complaint.
Consult a Colorado Fair Housing Attorney
Legal ActionIf you've suffered damages (like being forced to move or paying illegal pet fees), a Colorado fair housing attorney can advise you on a private right of action. Under the FHA, you may be entitled to actual damages, injunctive relief, and attorney fees.

Make Your ESA Letter Landlord-Proof
The best defense against an illegal denial is a well-documented ESA letter. Here is what makes a letter legally strong.
ESA Denial FAQ — Colorado
My landlord said ESA letters need to come from my "treating" therapist. Is that true?
No. HUD's 2020 FHEO guidance clarified that landlords cannot require you to use a specific therapist or an existing treatment provider. A letter from any Colorado-licensed mental health professional who conducts a genuine assessment is valid.
Can my landlord charge me if my ESA damages the unit?
Yes — for actual damages. A landlord may deduct the cost of damage caused by your ESA from your security deposit, the same as they would for any tenant damage. However, they cannot charge a separate pet deposit upfront.
My landlord said my ESA needs to be trained. Is that true?
No. ESAs are not required to have any specific training. They are not service animals. Their therapeutic benefit comes from their presence, not from task training. A landlord cannot deny an ESA for lack of obedience or task training.
Can a landlord evict me for having an ESA without approval?
If you have a valid ESA letter and submitted a proper accommodation request, a landlord who evicts you for having an ESA is likely retaliating illegally. Document everything and file a CCRD complaint immediately.
How long does my landlord have to respond to my ESA request in Colorado?
Under HUD guidance and Colorado law, landlords must respond within a reasonable time — generally 10 business days. If they don't respond, follow up in writing and note that the silence may constitute a constructive denial.
