Colorado Codifies ESA Housing Protections: What HB26-1045 Means
- Published on:

Days after the federal government narrowed how it handles emotional support animals in housing, Colorado wrote those protections into state law. The new law is signed, and it takes effect August 12, 2026.
When the U.S. Department of Housing and Urban Development issued its May 2026 enforcement memorandum, it shifted federal attention toward animals trained to perform disability-related tasks, leaving many emotional support animal owners asking a simple question: will my support still be recognized where I live?
In Colorado, the answer just became clearer.
On June 9, 2026, Governor Jared Polis signed House Bill 26-1045 into law. The law adds clear definitions of “assistance animal” and “emotional support animal” to the Colorado Anti-Discrimination Act, and it confirms that a qualified assistance animal is a reasonable accommodation in housing. In plain terms, Colorado chose to keep protections at the state level that the federal enforcement change had called into question.
It is worth being precise about timing, because it matters for renters making decisions right now. The bill is signed, but it does not take effect until August 12, 2026.
What HB26-1045 actually does
The law writes two things into Colorado’s civil rights statute. First, it defines an assistance animal to include both service animals and emotional support animals. Second, it confirms that people with a qualifying disability-related need may request reasonable housing accommodation for that animal, even where a building has a no-pet policy.
What that means for a Colorado renter is that once the law is in effect, an emotional support animal is recognized under Colorado law, not only under the federal Fair Housing Act, and housing discrimination complaints in the state are handled by the Colorado Civil Rights Division.
It reflects a broader shift since the federal change. With federal enforcement narrowed, the protections that matter most are increasingly the ones each state sets for itself. Colorado acted within days of the HUD memo, and it likely will not be the last state to respond.

What this does not change
A few honest clarifications, because responsible information is the whole point.
The law does not take effect immediately. Until August 12, 2026, the existing framework applies, so this is a protection to understand and prepare for, not one to assume is already active today.
It does not turn an emotional support animal into a service animal. Those remain distinct, and service animal status still depends on individual task training under the Americans with Disabilities Act.
And it does not remove the need for legitimate documentation. A valid ESA letter, issued by a licensed mental health professional after a real evaluation, is still how a reasonable accommodation request is supported.
What Colorado ESA owners can do now
Keep your documentation current and organized. Make sure your animal is well-behaved at home and around others. If you have a qualifying need and a properly issued ESA letter, you will be positioned to request a housing accommodation under both federal law and, as of August, Colorado law. And for any specific housing dispute, it is always wise to consult a qualified attorney.
If you have a qualifying need and are unsure whether your documentation is current, a licensed mental health professional can evaluate whether an ESA letter is appropriate for your situation.
Frequently asked questions
Did Colorado ban or protect emotional support animals?
Colorado protected them. HB26-1045 adds emotional support animals to the definition of “assistance animal” under state law and confirms they can be a reasonable housing accommodation.
When does the Colorado ESA law take effect?
The law was signed in June 2026 and takes effect August 12, 2026.
Does this apply to the rest of the country?
No. HB26-1045 is Colorado law. Other states have their own rules, which is why ESA housing protection increasingly depends on where you live.
Does an ESA letter still matter in Colorado?
Yes. A legitimate ESA letter from a licensed professional remains the basis for requesting a reasonable accommodation.
