Backyard Livestock Laws in Colorado
Colorado does not have a statewide preemption law that standardizes livestock ordinances across all municipalities — rules are set at the city and county level. This guide covers the major cities and counties in Colorado where backyard livestock questions are most commonly searched.
Colorado has strong urban agriculture traditions, particularly on the Front Range. Denver's ordinance is well-written and frequently cited as a model by other cities. Colorado's high-altitude climate means chicken-keeping involves winter care considerations that affect coop design requirements.
Major Colorado Cities — Chicken & Livestock Rules Summary

State-Level Registration Requirements
Beekeeping: Colorado requires registration of all managed honey bee hives with the Colorado Department of Agriculture. Contact your state's apiary division for current registration fees and requirements.
Livestock generally: Colorado does not require state-level registration for small-scale backyard livestock (chickens, goats, rabbits) below commercial thresholds. However, certain disease reporting requirements may apply if your flock shows signs of reportable diseases — contact your state Department of Agriculture's animal health division for details.
Finding Unincorporated County Rules in Colorado
If your property is in an unincorporated area (not within city limits), county zoning rules apply rather than municipal ordinances. County rules are generally more permissive than city ordinances. To confirm whether you're incorporated or unincorporated, check your county assessor's parcel records — the "jurisdiction" or "municipality" field will show if you're in a city or in unincorporated county territory.
