How Denver Handles Animal Ordinances: A Practical Guide

Denver maintains 204 local ordinances across all categories, and 12 of those deal specifically with animal ordinances. Here is a breakdown of what the city actually requires, what is prohibited, and where Denver falls on the strict-to-permissive spectrum compared to other cities.

Chickens & Livestock

Denver may allow backyard chickens with limits. Roosters typically banned in residential areas. Livestock requires agricultural zoning or minimum lot size.

Key details: Hens: Typically 4 to 8 allowed. Roosters: Usually prohibited. Livestock: Agricultural zones. HOA: Often prohibits all.

Unauthorized livestock: removal order. Nuisance: $100 to $500. Roosters in prohibited areas: immediate removal.

Cat Rules

DRMC chapter 8 requires every cat over six months in Denver to be licensed annually with Denver Animal Protection and current on rabies vaccination under Colorado state law. Cats must not run at large or be a nuisance under DRMC 8-44.

Key details: License age: Six months. Rabies: Required by state. TNR allowed: Through approved programs. Issuing agency: Denver Animal Protection.

Failing to license or vaccinate a Denver cat violates DRMC chapter 8 with fines starting at $80 per violation plus impound and reclaim fees. Repeat or nuisance-cat violations escalate to higher penalty schedule and possible court summons.

Mandatory Spay/Neuter

Denver has no mandatory spay-neuter ordinance for owned dogs and cats. Sterilization is voluntary, but Denver Animal Protection offers low-cost clinics and discounted licenses for altered pets under DRMC chapter 8 fee schedule.

Key details: Mandatory rule: None for owners. Adoption sterilization: Required at shelter. License fee: Discounted if altered. Low-cost clinic: DAP voucher program.

There is no penalty for keeping an intact pet in Denver, but reclaiming an intact pet impounded multiple times requires mandatory sterilization under DAP policy plus higher reclaim fees. Unlicensed intact pets pay top fee tier.

The rules around mandatory spay/neuter in Denver lean permissive, but that does not mean anything goes.

Microchipping

Denver does not require all owned pets to be microchipped, but the Denver Animal Shelter microchips every dog and cat at adoption. DRMC chapter 8 license is tied to the chip, helping reunite lost pets across Denver and Colorado.

Key details: Owner mandate: None citywide. Adoption rule: Mandatory at DAS. Chip clinic fee: Around twenty-five dollars. License linkage: Chip tied to license.

There is no fine for not microchipping. However failing to license a found pet under DRMC chapter 8 carries fines starting at $80 and impound fees. Outdated chip information is not penalized but slows reclaim.

Denver is more permissive than most cities when it comes to microchipping. That said, there are still limits.

Coyote Management

Denver Parks & Recreation and Colorado Parks & Wildlife share urban coyote response. Denver promotes hazing under its Urban Wildlife Plan; lethal removal is reserved for aggressive animals. Feeding wildlife is prohibited under DRMC chapter 8.

Key details: Lead agencies: Denver Parks plus CPW. Default response: Hazing and education. Feeding wildlife: Prohibited DRMC 8. Lethal removal: Aggressive animals only.

Feeding coyotes or other wildlife under DRMC chapter 8 is punishable by fines up to $999 per violation. Killing a coyote outside legal hunting or self-defense violates Colorado wildlife code with C.R.S. Title 33 penalties.

Pet Store Rules

Denver follows Colorado HB20-1084, prohibiting retail pet stores from selling commercially bred dogs and cats. Pet stores may only offer rescue and shelter animals for adoption. DRMC chapter 8 requires pet store licensing through Denver Animal Protection.

Key details: State law: Colorado HB20-1084. Effective date: January 1 2021. Allowed source: Rescue and shelter only. City license: DAP pet shop permit.

Selling commercially bred puppies or kittens at a Denver pet store violates HB20-1084 with civil penalties up to $1,000 per animal plus DAP license suspension. Failing to keep source records is a separate DRMC chapter 8 violation.

Compared to other cities, Denver takes a harder line on pet store rules. The enforcement and penalty structure reflects that.

Pet Limits

DRMC chapter 8 limits Denver households to three dogs and three cats per dwelling unit unless a pet animal facility license is obtained. Litters under four months count toward the limit at separate threshold; exemptions exist for licensed kennels.

Key details: Dog limit: Three per dwelling. Cat limit: Three per dwelling. Litter rule: Under four months exempt. Permit available: Pet facility license.

Keeping more than three dogs or three cats without a Denver pet animal facility license violates DRMC chapter 8 with fines starting around $150 per excess animal, escalating to $999 with administrative seizure of unlicensed animals.

Animal Hoarding

Denver does not have a standalone hoarding ordinance, but DRMC chapter 8 pet limits combined with Colorado C.R.S. 18-9-202 cruelty to animals reach hoarding cases. Denver Animal Protection investigates with police support and may seize animals.

Key details: City code: DRMC chapter 8. State statute: C.R.S. 18-9-202. Lead agency: Denver Animal Protection. Felony trigger: Aggravated cruelty repeat.

Animal cruelty under C.R.S. 18-9-202 is a class 1 misdemeanor with up to 364 days jail and $1,000 fine for first offense; aggravated cruelty or repeated hoarding can become a class 6 felony with prison time.

Compared to other cities, Denver takes a harder line on animal hoarding. The enforcement and penalty structure reflects that.

Dog Leash Laws

Denver DRMC §8-16 requires dogs to be on a leash in all public areas. Off-leash is only permitted in designated off-leash enclosures (dog parks). Leash length is not specified.

Key details: Leash Required: All public areas. Off-Leash Exception: Designated dog parks only. Code Section: DRMC §8-16. Dog Park Hours: Sunrise to sunset. Enforcement: Denver Animal Protection.

Fine for leash law violation: $100 (first offense), increasing with repeat violations. Dog impoundment possible.

This is not one of those rules that cities tend to ignore. Denver actively enforces its dog leash laws requirements.

Breed Restrictions

Denver's 30-year pit bull ban was lifted in 2021. Pit bulls now require a Breed-Restricted Permit ($30/year) plus assessment. Permit requires spay/neuter, microchip, and rabies vaccination.

Key details: Pit Bull Ban: Lifted January 1, 2021. Breed-Restricted Permit Fee: $30/year + $25 assessment. Requirements: Spay/neuter, microchip, rabies vax. Code Section: DRMC §8-67. Enforced By: Denver Animal Protection.

Keeping a pit bull without a Breed-Restricted Permit is unlawful. Fines and impoundment apply.

Exotic Pets

Denver DRMC Chapter 8 prohibits numerous exotic animals including big cats, wolves, foxes, raccoons, primates, venomous reptiles, and large constrictors. Violations carry significant fines.

Key details: Prohibited: Big cats, wolves, foxes, raccoons, primates. Also Prohibited: Venomous snakes, large constrictors. Code Section: DRMC Chapter 8. Enforcement: Denver Animal Protection. Max Fine: Up to $999.

Fines for prohibited exotic animal possession plus mandatory animal surrender. Fines can reach $999.

Compared to other cities, Denver takes a harder line on exotic pets. The enforcement and penalty structure reflects that.

Beekeeping

Denver allows beekeeping in certain residential zone districts. Maximum 2 hives per lot under 6,000 sq ft. Hives must be registered with Denver Animal Protection. Outdoor storage of bee equipment is prohibited.

Key details: Max Hives (under 6,000 sq ft lot): 2 hives. Registration Required: Denver Animal Protection. Outdoor Equipment Storage: Prohibited. Zone Restrictions: Allowed in select residential districts. Water Source: Recommended within 20 feet of hive.

Unregistered hives and violations of hive standards subject to code enforcement action.
