Sample Colorado ESA Accommodation Request Letter for Landlords (2026 Template)

Asking a landlord to make an exception to a no-pets policy can feel intimidating, even when you have a legitimate, documented need. In Colorado, tenants requesting a reasonable accommodation for an emotional support animal (ESA) are protected under the federal Fair Housing Act (FHA) and Colorado's own assistance-animal statute, but protection only works if the request is submitted correctly. A vague email or a letter from an unlicensed "registry" website is far more likely to be questioned or denied than a clear, well-documented request built on a legitimate ESA letter. This guide walks through exactly how to put together a Colorado ESA accommodation request letter, step by step, and includes a sample template you can adapt.

What You'll Need

• An ESA letter from a licensed mental health professional (LMHP) licensed in Colorado, typically an LCSW, LPC, LMFT, psychologist, psychiatrist, or a licensed primary care provider where permitted
• Your current lease agreement, so you can reference the specific no-pets or pet-fee clause
• Contact information for your landlord or property management company
• A written accommodation request letter (template below)
• A delivery method that creates a paper trail: certified mail with return receipt, a dated email, or your property portal's messaging system
• A folder (physical or digital) to keep copies of everything you send and receive

Step-by-Step: Requesting an ESA Accommodation From a Colorado Landlord

1. Confirm your need with a Colorado-licensed clinician

The foundation of any valid request is a genuine clinical relationship. Many people with anxiety, depression, PTSD, or other mental health conditions find that an emotional support animal is therapeutically helpful, but only a licensed clinician can determine whether an ESA is appropriate for your specific situation after an individualized evaluation. Colorado's assistance-animal statute (C.R.S. § 38-12-901 et seq.) and HUD's Assessing a Person's Request to Have an Animal as a Reasonable Accommodation Under the Fair Housing Act notice (FHEO-2020-01) both emphasize that documentation must come from a provider with real, direct knowledge of the client's condition, not a questionnaire-only website. For a fuller breakdown of how the FHA and Colorado law work together, see our guide to Colorado ESA housing rights under the FHA.

2. Complete the clinical evaluation

Expect a conversation about your history, current symptoms, and how an animal fits into your care. This isn't a formality the clinician skips through, it's what makes the letter legally meaningful. If the provider you're working with is licensed outside Colorado and has never spoken with you, that letter is unlikely to hold up if your landlord or a court scrutinizes it.

3. Receive your ESA letter with the required elements

A legitimate Colorado ESA letter should include the clinician's license type and number, the state of licensure, the date, a statement that you are under their care and that the ESA is recommended as part of treatment, and the clinician's signature on letterhead. It should not promise "guaranteed approval," reference an "ESA registration," or claim any air-travel benefit, airlines have not been required to accommodate ESAs since the Department of Transportation's 2021 rule change.

4. Draft your written accommodation request

Your request letter to the landlord is separate from the clinician's letter, and it's what actually starts the formal accommodation process. Keep it factual and brief: state that you are requesting a reasonable accommodation under the Fair Housing Act to keep an emotional support animal, reference the enclosed clinician documentation, and note that you understand you remain responsible for any damage the animal causes. If your building already advertises itself as having a strict no-pets policy, it can help to explicitly note that ESAs are not "pets" under fair housing law and are evaluated separately from pet policies.

5. Submit both documents together, with proof of delivery

Send the accommodation request letter and the ESA letter together, using a method that timestamps delivery. Certified mail with a return receipt is the most defensible option; a dated email to your property manager with both documents attached is usually acceptable too. Keep copies of everything.

6. Give the landlord a reasonable window to respond

HUD's guidance does not set a fixed number of days, but housing providers are expected to respond within a reasonable timeframe once they have what they need to evaluate the request. If weeks pass with no response, a polite written follow-up referencing your original submission date is appropriate.

7. Respond to reasonable follow-up questions

A landlord may, in some circumstances, ask limited follow-up questions if your disability or disability-related need isn't obvious and wasn't clearly addressed in the documentation. This is normal and doesn't mean your request is being denied. What a landlord generally cannot do is demand your full medical records, ask for a specific diagnosis, or require a particular form.

Re: Request for Reasonable Accommodation – Emotional Support Animal

Dear [Landlord/Property Manager Name],

I am writing to request a reasonable accommodation under the federal Fair Housing Act and Colorado law to keep an emotional support animal at [unit address]. I have a disability-related need for this animal, as documented in the enclosed letter from [Clinician Name, License Type and Number], a mental health professional licensed in Colorado.

I understand this accommodation applies to an emotional support animal rather than a pet, and I remain responsible for any damage the animal may cause to the unit, consistent with the terms of my lease.

Please let me know if you require any additional information to process this request. I can be reached at [phone] or [email].

Sincerely,
[Your Name]

Common Mistakes to Avoid

• Relying on an online "ESA registration" or ID card. HUD has stated plainly that these registries carry no legal weight; a landlord who denies a request based solely on a registry card, rather than an LMHP letter, is generally acting correctly.
• Using a clinician not licensed in Colorado without an established relationship. Out-of-state, questionnaire-only providers create the exact kind of documentation gap that leads to denials.
• Sending only a verbal or informal request. Without a paper trail, it's difficult to establish when the accommodation process started if a dispute arises later.
• Assuming the letter guarantees approval. A landlord must engage in an individualized review; a properly documented request improves the odds of a smooth process but does not eliminate the possibility of legitimate follow-up questions or, in rare cases, a denial.
• Not knowing your options if denied. If your accommodation request is refused or ignored, our guide on appealing an ESA letter denial in Colorado walks through the next steps.

What You May Expect

Tenants who submit a complete, well-organized request, a genuine ESA letter from a Colorado-licensed clinician paired with a clear written accommodation request, often find the review process moves more smoothly than an incomplete or informal request would. That said, every landlord and property management company evaluates accommodation requests individually, and outcomes are never guaranteed. Some buildings may take longer to respond, request limited clarifying information, or have questions specific to your lease terms.
