Summary

Antioch does not mandate spay/neuter for pets kept at home, but no unclaimed dog or cat may leave the Animal Shelter for adoption unless it is already sterilized or the adopter signs a sterilization agreement and posts a deposit, under AMC § 6-1.705.

§ 6-1.705 STERILIZATION. No unclaimed dog or cat shall be released for adoption without:

(A) Being sterilized; or

(B) A written agreement from the adopter guaranteeing that the animal will be sterilized and a sterilization deposit made. The sterilization fee deposit is established by resolution of the Council. If the animal is not sterilized within 14 business days after the date of purchase, the sterilization deposit collected at the time of adoption will be considered abandoned and the money applied to the General Animal Control Fund for use as the city may determine. (See Food and Agric. Code § 30503.)

Full Breakdown

705 gives adopters two paths: the animal is sterilized before adoption, or the adopter signs a written agreement guaranteeing sterilization and pays a deposit set by City Council resolution. If the animal is not sterilized within 14 business days after the adoption date, the deposit is treated as abandoned and the money is deposited into the General Animal Control Fund, cross-referencing Cal. Food and Agric. Code § 30503. 704(A)(3) requires an owner reclaiming a nonspayed or unneutered dog from impoundment to pay the fine set under Cal.

Food and Agric. 7 on top of the standard impound, boarding, license, and microchip fees. Together the three provisions push sterilization at the two points the city can reach an animal directly, adoption and repeat impoundment, rather than mandating it for every pet owner citywide.

Violations & Fines

Failing to sterilize an adopted animal within 14 business days forfeits the adopter's deposit to the General Animal Control Fund under § 6-1.705(B); failing to sterilize a twice-impounded dog or cat blocks its release entirely under § 6-1.704(B), and redeeming a nonspayed or unneutered impounded dog requires paying the state fine under Cal. Food and Agric. Code § 30804.7 in addition to standard redemption fees.

Frequently Asked Questions

Do all Antioch pet owners have to spay or neuter their animals?
No citywide mandate applies to pets kept at home. AMC § 6-1.705 requires sterilization only for dogs and cats adopted out of the Animal Shelter, and § 6-1.704(B) separately requires it before a second-impoundment redemption.
What if I adopt an unsterilized shelter pet?
You must sign a written agreement guaranteeing sterilization and post a deposit set by City Council resolution. If the animal isn't sterilized within 14 business days of adoption, AMC § 6-1.705(B) forfeits the deposit to the General Animal Control Fund.
Is there a fine for owning an unaltered dog picked up by Animal Control?
Yes. Redeeming a nonspayed or unneutered dog from impoundment requires paying the fine set under Cal. Food and Agric. Code § 30804.7, on top of the standard impound and boarding fees listed in AMC § 6-1.704(A).
