Fullerton, CA Animal Ordinances: Livestock (2026)

The City of Fullerton regulates livestock keeping through its Zoning Ordinance, which establishes where and under what conditions large animals may be maintained. In standard single-family residential (R-1) zones, multi-family residential (R-2, R-3) zones, and commercial or industrial zones, livestock keeping is not permitted. Horses, goats, sheep, pigs, cattle, and similar large animals are restricted to parcels carrying agricultural or equestrian-overlay zoning designations. These qualifying properties are concentrated in portions of north Fullerton near the Fullerton hills, where larger lot sizes accommodate animal husbandry. The number of animals permitted is tied to lot size, with minimum acreage requirements per animal head. All animal enclosures — including stables, barns, corrals, and pens — must meet the zoning district's setback requirements from property lines and neighboring structures. Manure must be managed through regular removal or composting in a manner that prevents odor, fly breeding, and groundwater contamination. Feed must be stored in sealed, rodent-proof containers. Properties must maintain adequate fencing to prevent animal escape. OC Animal Care provides animal control services and responds to complaints about loose livestock. The Fullerton Community Development Department at (714) 738-6884 administers zoning verification for livestock eligibility.
