What 2J changed
Voters approved ballot measure 2J in 2020, replacing the city's pit bull ban with a Breed-Restricted Permit.
Denver, a consolidated city and county of 715,522 people in 2020, has its own pet licensing rules and its own anti-discrimination office on top of Colorado law. Start with the free screening; a clinician licensed in Colorado reviews it and decides whether an ESA letter or a psychiatric service dog letter is supported.
Three tents pitched in order, from the first question to the answer.
A few minutes of questions about your health, your animal and the Denver home you rent.
A clinician licensed in Colorado reviews it and follows the state's rules on how the two of you must have met.
A supported letter arrives digitally after you choose a plan; if it is not supported, you are not charged.
Describe your pet and your household to see whether Denver needs a license now, whether it is free, and whether the breed-restricted permit applies.
Clear pricing for emotional support animal and psychiatric service dog letters written by a licensed mental health professional. Your screening is free, and you pay only if a clinician supports a letter and you decide to continue.

Denver was founded in 1858, during the gold rush, where Cherry Creek flows into the South Platte River, and it was named for James W. Denver, then governor of Kansas Territory. Its official elevation of exactly one mile gave it the Mile High City nickname, and the 105th meridian west, the reference line for Mountain Time, runs right through Denver Union Station.
Three dominoes, each showing the number at the heart of its rule.

A household may keep up to two dogs under the permit.

Three keys, each a reason the clinician's Colorado license counts here.
HB26-1045 put emotional support animals inside Colorado's definition of assistance animals from August 12, 2026, whatever the federal enforcement stance.
Colorado's counselors, psychologists, social workers, family therapists, addiction counselors and nurses must meet a client in person before an assistance animal finding.
Denver's Anti-Discrimination Office handles complaints arising inside the city, with a 180-day limit.
Six questions in two rows of stadium seats, one question to a seat.
Denver requires a license for every dog and cat six months or older within 30 days of the pet being in the city.
Yes. Denver's licensing page says city ordinance requires a pet to be spayed or neutered after six months of age.
A senior citizen 65 or older can license one pet with a free three-year license, and service dogs get a free three-year license; both still need free renewals to update owner and rabies details.
Yes, with a Breed-Restricted Permit. Ballot measure 2J replaced the city's pit bull ban in 2020; a household may have up to two, and regular licensing follows after three years without violations.
Denver residents can go to the city's Anti-Discrimination Office within 180 days of an incident inside city limits, or to the Colorado Civil Rights Division, which allows one year for housing cases.
For psychologists, counselors, social workers, family therapists, addiction counselors and nurses, Colorado law requires an in-person meeting before an assistance animal finding; physicians may also rely on telemedicine.
Five records from the same shelf, each a nearby Colorado page.
General information for Denver residents, current as of October 2026, and not legal advice. Licensing, permit and complaint rules come from the City and County of Denver and the State of Colorado and can change, so confirm them with Denver Animal Protection or the relevant office. Screening does not guarantee a letter. In a crisis, call or text 988.
From Union Station lofts to bungalows near City Park, a clinician licensed in Colorado can look at how your animal helps you live at home.
