Tracy, CA Animal Ordinances: Chickens & Livestock (2026)

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 — which make up the bulk of unincorporated land outside Mountain House and the city fringes — 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 §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.
