Summary
Phoenix does not require pet owners to spay or neuter animals. The only spay/neuter mandate in the City Code is a court order issued after an animal is legally declared vicious.
A. Upon determining an animal to be vicious, the court shall enter such orders as it deems necessary to protect the public. The court may order, but is not limited to the following: ... 5. That the animal be spayed or neutered. 6. That the animal be defanged or declawed.

Full Breakdown
Phoenix Code Chapter 8 (Animals) has no general spay/neuter requirement for dog, cat, or other pet owners. Spaying or neutering only becomes mandatory case-by-case: under Sec. 8-16.02, once a justice of the peace or City magistrate holds a hearing and determines an animal is vicious, the court may order it spayed or neutered as one of several possible conditions, alongside options like a warning sign, liability insurance, secure confinement, or destruction. Sec. 8-3.03 separately confirms a cruelty/neglect disposition hearing doesn't preclude a court from ordering an animal spayed or neutered.
Violations & Fines
No citywide fine for an unaltered pet. But once a court orders spay/neuter under a viciousness determination, ignoring the order is enforceable under Article III's penalty clause, Sec. 8-20, as a Class 1 misdemeanor.
