Phoenix has no mandatory spay or neuter ordinance. Sterilization remains voluntary citywide, but Maricopa County and partner clinics offer subsidized surgeries, reduced license fees for altered dogs, and free vouchers through the Spay Neuter Hotline and shelter adoption programs.
Unlike Los Angeles or San Jose, Phoenix City Code Chapter 8 does not require dogs or cats to be sterilized. Maricopa County uses incentives instead: an altered dog license costs roughly twenty dollars per year, while an unaltered dog license is markedly higher. The Spay Neuter Hotline of Arizona and the Arizona Humane Society run low-cost clinics, and MCACC sterilizes every shelter pet before adoption. Some HOAs and rental properties impose private spay/neuter rules. State law does not preempt cities from enacting mandatory ordinances, so the policy could change, but as of 2026 it remains voluntary.
No penalty for keeping an intact pet in Phoenix. Owners do pay higher annual license fees for unaltered dogs and may face higher impound or reclaim costs if an intact dog is picked up at large.
