When moods rise and fall, a steady animal at home can be part of what keeps routines on track. Colorado's 2026 law protects that kind of support in housing, and its deposit rules protect you when you move. A free screening starts the evaluation with a clinician licensed in Colorado.
The question is not the diagnosis by itself but its effect: how mood episodes limit work, sleep, relationships or self-care, and what your animal adds to the days in between. In Colorado, a psychologist, counselor or social worker who writes a housing finding must have met you in person; a physician may rely on telemedicine.
| Question | Emotional support animal | Psychiatric service dog |
|---|---|---|
| What it does | Steadies routines through its presence | Individually trained for disability-related tasks |
| At home | Protected as an assistance animal in Colorado housing | No extra charge for the dog in housing |
| Out in public | Follows pet rules in shops and on flights | Public places under C.R.S. 24-34-803 |
Since August 12, 2026, C.R.S. 24-34-301 counts an emotional support animal as an assistance animal.
Under C.R.S. 24-34-502.2, allowing the animal is presumed reasonable once the landlord had a chance for an interactive process.
C.R.S. 38-12-106 limits pet deposits and pet rent for pets; the 2026 act does not address fees for assistance animals.
The Colorado Civil Rights Division takes a housing complaint for up to a year after the refusal.

A landlord meets the law by mailing the statement to your last-known address, so give a new one in writing.
It has to list the exact reasons for anything kept; without it on time, the right to withhold is forfeited.
Before suing over a willful withholding, tell the landlord at least seven days ahead.
It can, when a clinician licensed in Colorado finds that the condition is a disability for you and that your animal meets a disability-related need.
HB26-1045 counts emotional support animals as assistance animals and presumes that allowing one is reasonable once the housing provider has had a chance for an interactive process.
Within one month after the lease ends or the landlord accepts surrender of the unit, whichever is later, unless the lease sets a longer period of up to 60 days.
No. C.R.S. 38-12-103 bars keeping any of it for normal wear and tear, and any amount kept needs a written statement of the exact reasons.
Willful retention makes the landlord liable for three times the amount wrongfully withheld, plus reasonable attorney fees and court costs. You must give the landlord seven days' notice before you file.

If your animal helps you stay steady, a letter from a clinician licensed in Colorado gives your landlord the documentation the state's law describes.
