ESA Letter in Denver, CO
from a Colorado-licensed therapist

About 51.2% of households in Denver rent their home, the highest renter share among Colorado's five largest cities. With a median gross rent of $1,831 a month, the right building is hard enough to find without a pet policy ruling it out.

Getting an ESA Letter in Denver, CO

What a Denver landlord actually needs from you is short: reliable confirmation, from someone licensed in Colorado, that you have a disability and that your animal helps with it. That is all an ESA letter is — and a properly written one says nothing more.

Colorado has no statutory waiting period, so a Colorado-licensed therapist can evaluate you and, if you qualify, your letter typically arrives by email about 15 minutes after approval. You talk with a therapist, by phone or video, about how your condition affects daily life and what your animal does for you. They decide; you do not buy an outcome.

Colorado protects assistance animals in its own law, so HUD's May 2026 enforcement change matters less here than in most states. Denver adds its own layer: Denver Revised Municipal Code ch. 28, art. IV, § 28-91 et seq..

Renting in Denver: What ESA Tenants Should Know

51.2% of Denver households rent, the highest renter share among Colorado's five largest cities. Median gross rent is $1,831 a month — 2nd-highest median rent of Colorado's five largest cities.

In a market like this, management companies tend to standardize pet rules across their buildings. The rule you meet at one property is often the rule at the next, which is why knowing how to request an accommodation matters more than finding a pet-friendly unit.

What Your ESA Letter Covers in Denver

It helps you
  • Ask for pet fees to be waived — Colorado law addresses this
  • Get a decision in writing, which you need if you have to escalate
  • Ask for an exception to a no-pet policy as a reasonable accommodation
  • Ask for an individual assessment of your animal instead of a blanket breed or weight rule
It does not
  • Give your animal access to stores, restaurants or workplaces — that is a trained service dog right under the ADA
  • Make your animal fly as a service animal — airlines treat ESAs as pets since 2021
  • Override a lawful denial for a direct threat, substantial damage or an exempt property
  • Need a registry, certificate, ID card or vest — none of those carry legal weight

ESA Housing Law in Denver

Three layers apply to a Denver rental. The strongest one that covers you decides your case.

Local

Denver Revised Municipal Code ch. 28, art. IV, § 28-91 et seq. — Denver's own ordinance bans discrimination in housing based on disability and many other traits, and the city's Anti-Discrimination Office enforces it.

Colorado

C.R.S. § 24-34-502 — Colorado Fair Housing Act — reasonable accommodation duty. Complaints: Colorado Civil Rights Division.

Federal

The Fair Housing Act still requires landlords to consider accommodation requests. Since May 22, 2026, HUD itself pursues complaints only for individually trained animals; your private right to sue is unchanged. What changed →

Who qualifies

Who May Qualify for an ESA Letter in Denver?

There is no official list of qualifying conditions. The test is whether a mental or emotional condition substantially limits a major life activity, and whether your animal helps with it. These come up most often:

What the evaluation looks for

  • You are 18 or older, or a parent or guardian takes part
  • No prior diagnosis required; many people are assessed for the first time
  • The animal already lives with you or will once the request is approved
  • A condition that limits daily life — sleep, work, school or relationships
  • You live in Colorado, so a Colorado-licensed therapist can evaluate you
Check if you qualify

How to Get Your ESA Letter in Denver

Three steps. You are not charged for a letter unless the therapist approves you.

1

Free screening

Start with a short screening so you know whether an evaluation makes sense for you before you book or pay anything.

2

Evaluation with a Colorado therapist

Your evaluation is with a therapist licensed where you live. They can approve you, and they can decline.

3

Your letter, ready to send

If you are approved, your signed letter is emailed within about 15 minutes, ready to attach to your request to a Denver landlord.

Why Denver Renters Choose Us

Written for 2026

Our guidance reflects HUD's May 2026 change and Colorado's own rules, so you are not working from outdated advice.

Private by default

Your letter confirms a need without naming a diagnosis, and your clinical information is handled under HIPAA.

Flat pricing

$129 for up to two animals. No subscription, no renewal auto-charge, no add-on "registration."

No registries, ever

We do not sell certificates, vests or ID cards, because they carry no legal weight and can weaken your request.

How to Use Your ESA Letter With a Denver Landlord

1Send a written request

Put it in writing. Two or three sentences are enough, plus your letter; a landlord's own "ESA form" is optional, not a requirement.

2Answer only what is fair

A landlord may verify the need. They are not entitled to your diagnosis or medical records.

3Keep the paper trail

Save a copy of everything you send and receive, with dates. Paper trails win disputes.

4If you are denied

Ask for the reason in writing, then contact Denver Anti-Discrimination Office (Agency for Human Rights & Community Partnerships) or Colorado Civil Rights Division. A HUD complaint has a one-year window.

CO letter checklist

What a Valid CO ESA Letter Must Include

Denver property managers see a lot of ESA paperwork. A letter missing any of these is easy to reject.

  1. A Colorado-licensed therapist's signature

    Out-of-state signatures are the most common reason letters fail.

  2. License number, type and issuing state

    Managers check it against the Colorado licensing board.

  3. A statement of disability-related need

    That you have a disability and the animal helps with it — never the diagnosis.

  4. A current date

    Most landlords treat a letter older than 12 months as stale.

  5. No registry certificate attached

    A purchased certificate undermines an otherwise good letter.

About the PSD letter: it is documentation from a licensed therapist, not a certificate or an ID. Under the ADA, public access comes from your dog being individually trained to do work or tasks for your disability. Businesses are allowed to ask only two questions and are not allowed to require paperwork. Nobody can sell you access rights — anyone who says otherwise is selling a novelty.

You are charged only after a therapist approves you. We may place a temporary authorization hold on your card beforehand to confirm it is valid; a hold is not a charge and is released if you are not approved.

100% refund if your landlord denies your ESA. If your housing provider refuses the accommodation after you submit a letter we issued, we refund what you paid in full. Full terms, including what a claim needs, on our refund policy page.

Questions

Denver ESA Letter FAQ

Is an ESA letter valid in Denver, CO?

Yes. Denver follows Colorado and federal fair housing law, and both recognize a letter from a licensed therapist as support for an accommodation request. What it will not do is work in stores, on planes or as a registration.

Denver also has its own ordinance (Denver Revised Municipal Code ch. 28, art. IV, § 28-91 et seq.), which adds a local layer.

How long does it take to get an ESA letter in Denver?

Colorado has no statutory waiting period, so a Colorado-licensed therapist can evaluate you and, if you qualify, your letter typically arrives by email about 15 minutes after approval.

Can a Denver landlord charge pet rent or a deposit for my ESA?

Colorado law addresses assistance animals independently of HUD, so ask in writing for fees to be waived and cite the state rule if you are charged. Damage is always chargeable. How fees work now →

Can my HOA or condo board in Denver refuse my ESA?

An association is a housing provider, so it has to consider the request instead of pointing at its own rules. It can still deny on the usual narrow grounds. Requests to HOAs and condo boards →

Can one letter cover more than one animal?

Yes, if the therapist finds that each animal helps with your disability. The $129 letter covers up to two animals; $199 covers three or more.

Do I need a Colorado therapist, or can anyone write my letter?

Use a therapist licensed in Colorado. Telehealth crosses state lines but licensure does not, and an out-of-state signature is the most common reason a letter gets rejected.

Do I have to tell my Denver landlord my diagnosis?

No. A landlord may verify that you have a disability-related need for the animal. They are not entitled to your diagnosis or your medical records, and a good letter does not include either.

Can my Denver landlord deny my emotional support animal?

They must consider the request, but may deny it for a direct threat, substantial damage, undue burden, an exempt property or documentation that is not credible. Ask for any denial in writing. Denver Anti-Discrimination Office (Agency for Human Rights & Community Partnerships) can help you respond. If you are denied →
