Zoning in Colorado

You should still contact the city in question to make sure that there was not a portion of the writings I might have missed or the laws have not changed.

Anyone who has any new information about chickens in cities not listed here, or zoning changes, please contact myself, Cami Naccarato at so I can update the information.

 *For space, pieces of the ordinances have been deleted that do not pertain to fowl.*




Dogs, cats, rodents, birds, reptiles, fish, pot-bellied pigs weighing less than 70

Animals may be kept within the City upon compliance with the following requirements:

C.In the event an animal control officer determines that a violation of this section has occurred, the animal control officer shall give the owner or keeper of the animal a written warning of the violation pursuant to this chapter. The owner or keeper shall be entitled to a period of three (3) days after the date on which the written warning is given to correct the violation. If the violation persists or recurs for any pet or hoofed animal at the same residence cited in the warning after the three (3) day period, the owner or keeper shall be subject to enforcement action under this chapter. No enforcement action for a violation of this section shall be taken more than six (6) calendar months after the date on which a written warning for that violation is given. If enforcement action is taken within six (6) months of the date on which a written warning was given, the issuance of a summons and complaint shall constitute written warning for the purposes of calculating a new six (6) month enforcement period. Only one warning per residence, per enforcement period, regardless if served on the owner or keeper, will be given.

D.The warning process to be employed by the animal control officer shall be as follows:

1. A written warning pursuant to subsection C of this section will be issued by the animal control officer if, upon investigation, the officer establishes that there is one witness to the unreasonably loud and persistent nature of the noise. The officer or the complaining witness may be relied upon as a witness in meeting this requirement.

2. The warning shall be sufficient if it cites this section, states that a complaint has been received, that the person's pet or hoofed animal is disturbing the peace of another in the neighborhood, identifies the date and time of the disturbance, identifies the animal disturbing the peace, identifies the witness to the disturbance and is identified as coming from within the City limits.

3. A warning is given under this section if it is posted on the owner's or keeper's premises.

4. The City shall keep records of all warnings given and the records shall be prima facie evidence that the warnings were given.

A corroborating witness shall not include the complainant nor a member of the complainant's household.

F.Upon a second conviction entered and in addition to any other penalties that may be imposed, the court may order the owner or keeper of the pet to abate the nuisance within five (5) days. Failure to abate the nuisance within five (5) days shall constitute a "contempt of court" as defined in chapter 11 of this Code.

G.For the purpose of this section, "neighborhood" means the area within five hundred feet (500') of the exterior boundaries of the premises where the pet resides; "disturb" means to unreasonably annoy, perturb or interfere with the quiet enjoyment of another's premises.

H.Among the circumstances which may be considered in determining whether reasonable grounds for belief have arisen that an owner's or keeper's pet or hoofed animal is in violation of this section are:

1. The time of day.

2. The location of the noise.

3. The frequency of the noise.

4. The length of time for which the noise persists. (Ord. 96-131; Ord. 01-42; Ord. 03-31; Ord. 04-178)



As of June 2011, Denver now allows each lot to have up to 8 chickens and ducks (total of 8) and 2 dwarf goats.  These must be females, although there some brief exceptions for newborn male goats and neutered goats. 

$25.00 one time registration for the property.

Total estimated time to get permit assuming a reasonable ten days from Animal Control and a few extra days in between: 60 days

Time expended in getting an approval: 12.5 hours, which includes 1 letter and 1 trip to Animal Control, a meeting with Animal Control at your property, 3 trips to Zoning, posting signs on your property, getting letters of support from your neighbors.

Total application fees: $150

Total annual fees: $70

Not surprisingly, the rules are sufficiently complex and expensive that they provide a significant disincentive to obtaining a permit.   From a financial perspective, it is far cheaper for a potential chicken owner to drive to the supermarket and purchase eggs that were trucked to the store, rather than to produce eggs in the backyard.   (Of course, this assessment does not take into consideration the cost to the environment or to the metro region’s air or traffic congestion.)   I spoke to two animal control staff on February 17, 2009 and the answer to my question about how many such permits have been granted was, “a handful,” and “just a few.”  (The Zoning Department does not compile a list of applicants for such permits as their records are by address; I have requested a list of applicants from Animal Control via the Colorado Open Records Act.)  Consequently, this leads some Denver residents into becoming chicken outlaws, an observation I confirmed by internet research into the growing underground chicken movement in Denver. 

1Sec. 8-92.  Nuisance-free facilities prerequisite to granting.
A permit to keep livestock or fowl within the city shall not be granted unless the owner or possessor provides facilities which will reasonably assure the manager that the premises will be maintained in a sanitary condition, free from insects and rodents, offensive odors, excessive noise, or any other conditions which constitute a public nuisance.

2 What kind of livestock are permitted?  The law contains no limits, but at least some of the animals contemplated are mentioned in the Zoning Ordinance:
Sec. 8-91.  Livestock or fowl permit required.
It shall be unlawful for any person to keep, maintain, possess or harbor on any property within the city any livestock or fowl such as, but not limited to, horses, mules, donkeys, burros, cattle, sheep, goats, swine, chickens, geese, ducks or turkeys, unless a livestock or fowl permit therefor has been issued by the manager. Such permit is required to be renewed annually for a fee of fifty dollars ($50.00) for each application.

3 Sec 59-38(a)(12)e.   Keeping of animals  . In addition to the animals permitted by the zoning administrator, the zoning administrator may authorize, upon application in specific cases, subject to terms and conditions fixed by the board and pursuant to the conditions hereinafter set forth, an exception permitting the keeping of animals in connection with the operation of a single unit dwelling or a dwelling unit in a multiple unit dwelling. Such exception shall be personal to the applicant therefor. Notwithstanding other provisions of chapter 59, which limit the number of animals, the breeding of animals may be permitted. 
1.   The application shall be filed in the name of the land owner.
2.   The owner/tenant seeking the exception must occupy the subject property as his/her primary residence;
3.   The animal shall be kept solely as a pet; a hobby; for educational, research, rehabilitation or propagation purposes; or for the production of food products for personal consumption by the resident;
4.   The application shall contain provisions which ensure that the exception will not substantially or permanently injure the appropriate use of adjacent conforming property. In determining that this condition will be met, the zoning administrator shall consider the following factors:
i.   The type of animal to be kept;
ii.   The number to be kept;
iii.   The maximum size of the animal;
iv.   The space or area in which the animal is to be kept and whether or not other animals may occupy that same space;
v.   The methods by which any sanitation problems will be controlled;
vi.   The methods by which abutting residents will be protected from any nuisance; and
vii.   The applicant's intent to allow reproduction.
5.   The applicant shall have written approval from the department of environmental health;
6.   The applicant shall have written approval from the division of wildlife, Colorado Department of Natural Resources, if applicable, for species of animals considered to be wildlife;
7.   The applicant shall have notified abutting owners about the proposed animal and shall have requested letters of support or petitions of consent from such owners. If any of said owners fail to consent, the zoning administrator shall consider the circumstances, including any letters or petitions of opposition. Further, the zoning administrator shall give serious consideration to any letter from a physician stating that a resident living nearby is allergic to some feature of the proposed animal and may have a serious reaction if exposed to such animal.
8.   Any structure erected for the shelter of such animal shall comply with all regulations for the zone district in which such property is located. If a variance is required for any such structure, an application for a variance must be made to the board of adjustments. Any such structure shall be maintained in accordance with the building and housing codes and shall be subject to inspection by the building inspection division and the department of environmental health.
9.   An approved exception for an animal shall not be valid until the applicant has executed an agreement listing the terms and conditions fixed by the zoning administrator and the applicable conditions set forth above. Such agreement shall be recorded with the clerk and recorder. The permit for an approved exception shall expire at such time as the applicant no longer resides at the property, or discontinues the keeping of subject animal.
10.   Upon receipt of a complaint from an abutting property owner, the department of zoning administration shall investigate. If any deviations from the conditions listed in the agreement exist, an order may be issued terminating the exception. The order may then be appealed to the board of adjustments for review.



6.04.170 Certain animals prohibited. It shall be unlawful for any person to keep, harbor, care

for or possess the following animals within the city of Evans.

A. Any animal having poisonous bites.

B.

Furthermore, an additional 2500 square feet of open area is required for each animal in excess of three. This open area must be located at least 50 feet from any residence, business or other building intended for human habitation.

Jefferson County


Jefferson County Planning & Zoning is processing several revisions to the Zoning Resolution. In general, the revisions allow backyard chickens and bees and consolidate the agricultural, commercial, corridor, industrial, mobile home, mountain residential, residential, and suburban residential districts. A draft of these changes is available for public review on our website. The direct link to the changes is, it can also be navigated to by going to the main Planning & Zoning page ( and then following the link under the “Zoning Resolution Revisions” announcement.  Please email comments to Heather Gutherless or Nina Ruiz by February 20, 2013. More information regarding these changes is outlined after the Hearing Dates. 

Hearing Dates:   
Planning Commission: Wednesday, March 6, 2013 at 6:15pm
Board of County Commissioners: Tuesday, March 26, 2013 at 8:00 am.
Both hearings are held in Hearing Room 1 of the Jefferson County Administration and Courts Building, 100 Jefferson County Parkway, Golden. Public testimony is welcomed.
Bees and Chickens:
The proposed regulations regarding keeping chickens and bees on residential properties are located in Section 5 – Accessory Uses. These revisions are a result of many inquiries and requests to keep chickens and/or bees on residentially zone properties.  Currently, chickens and bees are allowed in the County’s Agricultural Districts and chickens are allowed in the Suburban Residential Districts, Mountain Residential Districts and the Residential-One District.
The main changes to this section include:
Ø Allows for the keeping of bees and chickens on single family detached, two-family dwelling or duplex residential lots through a miscellaneous permit.
Ø Maximum number of chickens allowed is 6. No roosters allowed.
Ø Allows one bee hive for each 4,000 square feet of lot area.  
Ø Permits for either bees or chickens may be revoked at any time for failure to comply with the provisions of the Zoning Resolution or any other local, state or federal laws.
The Planning Director discussed the benefits of keeping backyard chickens in a blog post on November 20, 2012. You can view that post by going to:
District Consolidation
The Zone Districts are currently broken into one section for each specific zone district. For example, the Agricultural-One District is its’ own section, Agricultural-Two District is its’ own section, and Agricultural-Thirty-five District is its’ own section. Planning Staff has consolidated all related zone districts into one section and has reformatted the information on uses, setbacks, heights and lot sizes into chart format, rather than in paragraph format. So in the consolidation, all Agricultural Zone Districts are shown in the Agricultural District section, rather than being split into 3 different sections. This consolidation was completed for the agricultural, commercial, corridor, industrial, mobile home, mountain residential, residential, and suburban residential districts. For the most part, the consolidation did not change the uses and standards in the districts, however, there were some instances where language needed to be changed.  Additionally, other changes that staff felt were minor, housekeeping-type changes are also included in these revisions.
All changes are outlined in the “Summary of Proposed Changes” sheet that is on the same website as the draft text.

Keeping livestock (chickens) is not allowed by City of Westminster ordinance. The ordinance also requires a property to be at least ten acres to support livestock within city limits. Livestock is defined by the state and federal government and cannot be changed to pet status by the City of Westminster. Any attempt to get a variance for your residential property would need to be presented to City Council during a Council meeting.
