Maricopa County has no mandatory spay or neuter ordinance and Arizona has no statewide requirement. Sterilization is voluntary, but the county and partner clinics offer subsidized surgeries, discounted altered-dog license fees, and free vouchers through the Spay Neuter Hotline of Arizona.
Neither Arizona statute nor Maricopa County code requires sterilization of owned dogs or cats. The county uses incentives instead: an altered annual dog license costs roughly twenty dollars while an unaltered license is markedly higher. Every animal adopted from MCACC is sterilized before release. The Spay Neuter Hotline of Arizona, the Arizona Humane Society, and AZCAAS run rotating low-cost clinics with vouchers for low-income residents and feral colony caretakers. Some HOAs and rental properties impose private sterilization rules. As of 2026 there is no state preemption of local mandatory ordinances, so policy could change in any Maricopa city, but the countywide default remains voluntary.
There is no county penalty for keeping an intact pet. 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 by MCACC.
