Backyard Livestock Laws in Arizona

Arizona 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 Arizona where backyard livestock questions are most commonly searched.

Arizona is notable for Phoenix's highly permissive chicken ordinance — up to 20 hens in residential zones is exceptional for a major U.S. city. Arizona's Africanized honeybee presence (particularly in the Phoenix metro and southern Arizona) means bee ordinances are among the most regulated in the Southwest, with additional requirements for Africanized-resistant queen stock in some areas.

How to Find Your Specific Arizona Rules

Search your city or county name on Municode.com and use the keyword search for "chickens," "poultry," or "livestock." For unincorporated county areas, search your county's Planning Department website directly. Our zoning code reading guide walks through the exact process.

State-Level Registration Requirements

Beekeeping: Arizona requires registration of all managed honey bee hives with the Arizona Department of Agriculture. Contact your state's apiary division for current registration fees and requirements.

Livestock generally: Arizona 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 Arizona

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.

Frequently Asked Questions

Arizona's Right to Farm Act protects established agricultural operations from nuisance suits — but it generally applies to farms in agricultural zones, not new residential livestock keeping in urban or suburban areas. Courts in most states have held that Right to Farm protections don't override municipal zoning restrictions on residential livestock. Consult a local attorney if you believe a Right to Farm argument applies to your specific situation.

Municode.com publishes updated codes but may lag behind the most recent amendments by weeks or months. For the absolute current version, contact your city's Planning or City Clerk's office and request confirmation of the current livestock provisions. This is especially important in rapidly-changing ordinance environments — several Arizona cities have updated their chicken rules in the past 2–3 years.

The city's ordinance applies regardless of whether you own or rent. The additional layer for renters: your lease agreement. Even if the city permits chickens, your landlord can prohibit them in your lease. Get written landlord approval before acquiring any animals, and confirm that the property meets all setback and lot size requirements even if the ordinance allows animals at that zoning level.

Disclaimer: This page provides general informational guidance only. Ordinances vary by city and county and change frequently. Always verify current rules with your local planning department before acquiring any animals.
