Tustin, CA Animal Ordinances: Livestock (2026)

Tustin Municipal Code Sec. 4222 states it is "unlawful to keep any equine, bovine, swine, sheep or goat within the corporate city limits, except in the R-A District and, where authorized by development guidelines, PC Districts," and that "a use permit shall be required for the keeping of such animals within these districts." In practical terms, Tustin's standard single-family neighborhoods cannot keep horses, cows, pigs, sheep or goats at all; only properties zoned R-A (Residential Agricultural) or an authorizing Planned Community can do so, and only after obtaining a use permit. Section 4221(c) reinforces this by prohibiting the keeping of animals or fowl for commercial purposes in any residential zone other than the R-A District or an authorized PC District. The keeping or maintenance of animals must also conform to the City's zoning regulations (TCC Sec. 4205, amending the adopted county definition to reference Tustin zoning). All livestock keeping remains subject to the general nuisance and sanitation rules of TCC Sec. 4224, which bar conditions causing fly-breeding, obnoxious odors or disturbance of neighbors. Because livestock are confined to a narrow zoning category, owners should confirm their parcel's zoning and secure a use permit through Tustin Community Development before bringing any large animal onto the property.
