Residential Zoning Pet Limits in Colorado: What Pet Owners Need to Know
June 15, 2026
If you share your home with multiple dogs or cats in Colorado, the number of pets you are legally allowed to keep may depend entirely on your zip code. There is no statewide law limiting the number of pets per household in Colorado — but that does not mean you are free to keep as many animals as you like. Local governments across the state have stepped in with their own ordinances, and the rules can vary dramatically from one municipality to the next.
Understanding residential zoning pet limits in Colorado helps you stay compliant, avoid fines, and protect the animals you care for. Whether you rent, own, or live under an HOA, the rules that apply to you are worth knowing before you bring another pet home.
Does Colorado Have a Statewide Pet Limit
Colorado is among the states that do not set a statewide limit on the number of dogs a household can own. The same is true for cats and most other common pets. Colorado state law does not establish a universal cap on pet ownership for residential properties.
In states like Colorado, limits are typically set at the county or city level, where local ordinances often restrict households to around 2 to 6 dogs depending on location and zoning. This means the answer to “how many pets can I have?” is almost always a local one.
What the state does regulate is how pets are kept and cared for. Current rabies vaccinations for dogs and cats over the age of three months are required in Colorado, and pets will need to be vaccinated prior to entry, with a Certificate of Veterinary Inspection issued within 30 days prior to entry. Beyond health and welfare standards, Colorado delegates the question of pet quantity almost entirely to municipalities and counties.
Key Insight: Colorado has no statewide pet limit, but nearly every city and county has its own ordinance. Always check your local municipal code before adding a pet to your household.
One area where the state has moved recently involves housing. Beginning January 1, 2026, all state-financed affordable housing developments must allow tenants to keep up to two pets (dogs or cats). This does not set a statewide household pet limit, but it does establish a minimum access floor for pet owners in qualifying housing.
How Residential Zoning Affects Pet Limits in Colorado
Zoning is one of the primary tools local governments use to regulate how many animals you can keep. The zone district your property falls under — whether single-family residential, multi-family, agricultural, or otherwise — often determines which animals are permitted and in what numbers.
Each city will specify how many domestic animals are allowed per household, and this is usually dictated by the city zoning code. In practical terms, this means a home on a standard residential lot may face stricter limits than a property zoned agricultural, where larger numbers of animals are more commonly permitted.
Exceeding your zone’s pet limit can trigger a separate classification. If a property exceeds the codified limitation for domestic pets, it may be considered a kennel, which is not a permitted use within residential zones. A kennel is allowed only in the Agricultural (A) zone. This distinction matters because operating an unlicensed kennel in a residential zone can result in enforcement action even if your intent is simply to keep personal pets. You can learn more about how Colorado handles this boundary in our guide to kennel zoning laws in Colorado.
Multi-family housing typically faces tighter restrictions than single-family homes. Single-family detached homes may allow up to 6 dogs or cats or any combination with no more than 4 adult dogs, while multi-family residences with a shared common wall may be limited to up to 2 dogs or cats or any combination. These distinctions reflect the shared-space nature of apartment and townhome living, where noise and waste from animals more directly affects neighbors.
Important Note: Zoning classifications can change, and municipalities update their codes periodically. Always verify the current rules through your local planning or animal control department rather than relying solely on older published sources.
Dog and Cat Limits in Colorado by City and County
Because Colorado leaves pet limits to local governments, the rules you face depend entirely on where you live. Below is a breakdown of known limits for major cities and counties across the state. Always verify directly with your local municipality, as ordinances are subject to change.
| City / County | Dog Limit | Cat Limit | Combined / Notes |
|---|---|---|---|
| Colorado Springs | 4 adult dogs | 4 adult cats | Adults defined as over 4 months; one litter permitted additionally |
| El Paso County (unincorporated) | 4 adult dogs | 4 adult cats | Up to 8 animals total; kennel license required above thresholds |
| Jefferson County (unincorporated) | 3 combined | 3 combined | Max 3 total domesticated pets in residential zones |
| Northglenn | 4 combined | 4 combined | No more than 4 dogs, cats, or combination total |
| Aurora | Household limit | Household limit | Separate ordinances for dogs, cats, ferrets, and rabbits |
| Fort Collins | Limit applies | Limit applies | Limits number of animals per household; check local code |
| Boulder | Limit applies | Limit applies | Limits pets in rental properties; waste disposal rules enforced |
The City of Colorado Springs allows up to four dogs and four cats over four months of age per property, and dogs and cats are required to be vaccinated and licensed through the Humane Society of the Pikes Peak Region.
In Jefferson County’s residential zone districts, a maximum combined total of three domesticated pets may be kept. Domesticated pets include but are not limited to cats, dogs, potbelly pigs, or similar domesticated animals.
In Northglenn, a 2025 ordinance limits each residential dwelling unit to four dogs, four cats, or a combination of four animals total. Residents requested the change because of excessive pet waste and noise in some neighborhoods. Surrounding cities had pet limits in place already, and Northglenn was the only municipality in Adams County without one.
The City of Aurora’s pet limit applies to the entire household, and a combination of different animals is allowed but cannot exceed the limit for each species. Livestock is not permitted unless allowed by zoning provisions of the City Code. Aurora maintains separate ordinances for dogs, cats, ferrets, and rabbits.
Fort Collins implements pet registration and leash laws and limits the number of animals permitted per household. Boulder enforces pet waste disposal rules and limits the number of pets in rental properties, and landlords must ensure tenants follow clean-up requirements.
Pro Tip: Even within a city, limits can differ by zoning district. A property zoned single-family residential may allow more pets than one in a multi-family or planned unit development zone. Check both your city’s animal ordinance and your specific zoning designation.
Limits on Other Pets in Colorado
Dogs and cats are not the only animals subject to residential zoning limits in Colorado. Many municipalities regulate chickens, rabbits, hoofed animals, exotic species, and more — often with specific requirements tied to lot size, enclosure standards, and permits.
Potbellied Pigs
Although hogs and pigs are generally prohibited in Colorado Springs, up to two potbellied pigs may be kept in any household or dwelling. Potbellied pigs cannot exceed 100 pounds, must be registered with the Humane Society of the Pikes Peak Region, and must be spayed or neutered by four months of age. All potbellied pigs must be tattooed or implanted with a microchip containing identifying information by four months old. When combined with dogs and cats, potbellied pigs are limited to two per household, and the maximum number of dogs, cats, and pigs in any household shall not exceed four total animals.
Hoofed Animals
In Colorado Springs, hoofed pets are limited to two per household or dwelling, except that three or four hoofed pets may be kept where specific lot standards are met. Hoofed pets shall not be counted for purposes of limiting the total number of cats, dogs, or other pets that a household may keep. In Jefferson County, some zonings allow for horses if certain conditions are met.
Chickens and Rabbits
Colorado Springs allows property owners to keep up to ten rabbits or chickens aged six months or older. Roosters are prohibited. Many of Jefferson County’s residential zone districts allow backyard poultry and honeybees to be kept on property with a Miscellaneous Permit, but may limit the size of the coop, the number of animals, or the number of hives.
Exotic Animals
Exotic animals are those which are not commonly domesticated nor common to North America, or which, irrespective of geographic origin, are of a wild or predatory nature. Most Colorado municipalities prohibit or heavily restrict exotic animal ownership in residential zones. Aurora prohibits any feline species not commonly classified as a domesticated house cat (such as lions, tigers, bobcats, and lynx), foxes, wolves, wolf hybrids, coyotes, crocodilians, and monitor lizards.
There may be exceptions to the number and type of animals you can legally own, such as potbelly pigs, fowl, or certain hoofed animals, and these exceptions will vary by jurisdiction. Checking your specific municipality’s code is essential for any animal that falls outside the standard dog-and-cat category.
HOA and Landlord Pet Rules in Colorado
Even if local zoning law permits a certain number of pets, your homeowners association or landlord may impose tighter restrictions. These private agreements operate independently of municipal ordinances and can be more limiting than what city or county code allows.
Jefferson County strongly encourages residents to check with their Homeowners Associations before keeping animals, as each Association may have covenants or restrictions beyond those of the County. This is standard practice across Colorado — HOA rules frequently cap the number of pets, restrict breeds, set weight limits, and require pets to be registered with the association.
For renters, landlord policies add another layer. If you are renting, make sure to check with your landlord or apartment rental company about any animal or breed-specific bans, regardless of the city laws. A lease may prohibit pets entirely or limit you to one animal even when local ordinance would allow more.
Colorado has moved to address some of the most restrictive landlord practices in publicly financed housing. A bill on pet rentals (HB 25-1207) was signed into law in May 2025. This bill primarily targets affordable housing developments receiving public financing, prohibiting breed or weight restrictions and mandating that these new developments be pet-inclusive starting in 2026.
On the insurance side, Colorado law already prohibited insurers from denying homeowners insurance based solely on dog breed, and the new law extends these protections to all residential structures, including rental properties, ensuring that both homeowners and renters are protected from breed discrimination.
Common Mistake: Assuming that because your city allows four pets, your HOA or lease does too. Always review your HOA covenants and lease agreement separately from municipal ordinances — the most restrictive rule is the one that applies to you.
If you rent and your landlord imposes pet limits, pet-related security deposit charges are strictly limited in Colorado, with the security deposit limit capped at $300 per pet, and this amount must be fully refundable to the tenant.

How to Find the Pet Limit Where You Live in Colorado
Because pet limits in Colorado are set locally, the most reliable way to find the rules that apply to you is to go directly to your local government. Here is a practical process for tracking down the correct information.
- Identify your jurisdiction. Determine whether your property falls within city limits or in an unincorporated area of a county. The rules for unincorporated Jefferson County, for example, differ from those inside the city of Lakewood even though both are in the same geographic area.
- Look up your zoning designation. Most Colorado counties and cities offer online zoning maps or parcel lookup tools. Your zoning designation (such as R-1, R-2, or A-1) determines which animal regulations apply to your property.
- Search your municipality’s municipal code. Most Colorado cities publish their full municipal code online. Search for “animal,” “pet limit,” or “domestic animals” within the code. Each city specifies how many domestic animals are allowed per household, and this is usually dictated by the city zoning code.
- Contact animal control or planning and zoning. If the code is unclear, call your local animal control department or planning office directly. Exceptions vary by jurisdiction, so consulting your city or county code and contacting your local code enforcement or zoning department is recommended.
- Review HOA documents. If you live in a planned community, pull your CC&Rs (Covenants, Conditions, and Restrictions) and bylaws. These documents will spell out any pet limits that apply on top of local ordinances.
- Check your lease. Renters should review their lease and any pet addendum for specific limits, breed restrictions, and fee requirements.

Penalties for Exceeding Pet Limits in Colorado
Violating a local pet limit ordinance in Colorado can carry real consequences. The severity depends on the municipality, the number of animals involved, and whether the violation is treated as a civil or criminal matter.
Fines and Citations
Cities and towns are permitted to institute limits on the number of pets, and failure to comply could result in fines or other penalties, depending on the municipality. In most cases, a first offense results in a written warning or a civil fine. Repeat violations typically escalate in cost.
Court Orders and Animal Removal
In more serious cases, courts can order the removal of animals from a property. The City of Northglenn stated that failing to report extra pets by the deadline could result in enforcement action, including a potential court order requiring pet removal. This is not unique to Northglenn — many Colorado municipalities have similar enforcement language in their ordinances.
Kennel Classification
Exceeding the residential pet limit may cause your property to be reclassified as a kennel, which carries its own set of zoning and licensing requirements. If a property exceeds the codified limitation for domestic pets, it may be considered a kennel, which is not a permitted use within residential zones. A kennel is allowed only in the Agricultural (A) zone. Operating an unlicensed kennel in a residential zone can result in ongoing violations and significant fines. See our guide to kennel zoning laws in Colorado for more on how this classification works.
How Enforcement Typically Works
Most Colorado municipalities rely on a complaint-driven enforcement model rather than active inspections. Authorities generally are not going door to door conducting random pet checks; if they receive a complaint, they will investigate that complaint, or if they are at the home for a different reason, that might be something they issue a citation for.
Pro Tip: If you currently exceed your local pet limit, check whether your municipality offers a grandfather or “previously owned pet” exemption. Some cities, like Northglenn, allowed residents to register existing pets before a new ordinance took effect to avoid enforcement action.
Foster Pet Considerations
Pet foster parents face a particular challenge under local ordinances. Most municipalities with pet limits do not make an exception for foster pet parents, even though the Colorado Code sets the state limit at eight total foster pets. If you foster animals, contact your local animal control department to understand how your municipality handles temporary foster situations before taking in additional animals.
Understanding the rules in your specific location is the most effective way to avoid penalties.
