Rancho Cucamonga, CA Animal Ordinances: Mandatory Spay/Neuter (2026)

Section 17.88.020(C)(4)(b), the small-livestock standards for miniature goats, miniature pigs and similar-sized animals, states that miniature goats must be neutered by four months of age and miniature pigs must be spayed or neutered by four months of age. The same subsection separately requires that male miniature pigs two years of age or older have their tusks properly trimmed, a welfare and safety measure tied to keeping these animals in residential yards under the small-livestock rules of Table 17.88.020-1. Small livestock containment areas housing these animals must also provide at least 10 square feet of permeable outdoor space per animal for poultry/rabbits and 130 square feet per miniature goat or pig, plus 4 square feet of indoor space per poultry/rabbit, and shelters must sit at least 10 feet from a neighboring residential property line and 20 feet from the nearest primary dwelling (Section 17.88.020(C)(4)(a)).

The chapter's animal-keeping standards do not extend a spay/neuter mandate to household cats and dogs or to any other livestock category; those animals are regulated only by the numeric caps in Table 17.88.020-1 and the general nuisance and welfare standards in Section 17.88.020(B) and (D).
