Riverside, CA Animal Ordinances: Livestock (2026)

Riverside's zoning map reflects the city's agricultural past with significant areas still designated agricultural or rural residential. Under RMC Title 19 (Zoning), larger livestock — horses, cattle, sheep, goats, pigs, llamas, and alpacas — are permitted only in agricultural (A) and rural residential (RR, RC) zones, generally requiring a minimum lot size of 20,000 square feet to 1 acre depending on the species. Horses typically require at least half an acre with appropriate stabling and setbacks from neighboring dwellings (commonly 40-75 feet). Cattle and larger livestock require additional acreage. Pigs are the most restricted because of odor and sanitation concerns; even where allowed, they typically require larger parcels and enhanced setbacks. Slaughter for commercial purposes is prohibited in residential zones. Manure must be managed to prevent odor and fly nuisances; runoff into storm drains violates the Clean Water Act. Enforcement is shared among Riverside Code Enforcement, Riverside County Animal Services, and the County Agricultural Commissioner. Legal nonconforming livestock operations predating annexation or rezoning may continue under grandfathering rules until the use is abandoned or expanded.
