San Joaquin County is heavily agricultural, and livestock is broadly permitted. Chickens (including roosters), goats, horses, and cattle are allowed as-of-right in AG, AU, and AG-80 zones on appropriate lot sizes. Residential zones (R-R, R-L) allow limited poultry with coop setbacks; the Right to Farm Act (Civil Code Β§3482.5) protects existing ag operations from nuisance complaints.
San Joaquin County's Development Title treats animal-keeping very differently from urban jurisdictions. On AG, AG-40, AG-80, and AU (Agricultural-Urban Reserve) zoned parcels β which make up the bulk of unincorporated land outside Mountain House and the city fringes β cattle, sheep, goats, horses, swine, and poultry including roosters are allowed by right subject to lot-size and density standards (e.g., 1 horse per 20,000 sq ft net, larger densities for commercial dairy/poultry). R-R (Rural Residential) zones typically allow 6 hens and limited 4-H livestock on lots 1 acre or larger. R-L suburban residential zones generally permit up to 4 hens with coop setbacks of 20 feet from dwellings on adjacent parcels; roosters are prohibited in R-L and denser. The Right to Farm Act (California Civil Code Β§3482.5) plus San Joaquin County's right-to-farm ordinance (disclosed on recorded deeds) bars nuisance lawsuits against established agricultural operations, including smells, dust, and pre-dawn rooster crowing, that have been ongoing for more than 3 years. Commercial dairies, CAFOs, and poultry operations also fall under SJVAPCD air permits and Regional Water Quality Control Board waste discharge requirements.
Unauthorized livestock in urban residential: 10-day notice to remove, $100β$500 per day. Rooster in R-L: immediate removal order. Nuisance conditions (manure, vectors): $100 first, $500 repeat, referral to Environmental Health.
