San Ramon, CA Animal Ordinances: Livestock (2026)

San Ramon is a fully suburban master-planned community without meaningful agricultural zoning. The city's Development Code and Zoning Ordinance restrict livestock (horses, cattle, goats, sheep, pigs, llamas) to properties specifically zoned for agricultural use, of which essentially none exist within city limits. All residential zones in San Ramon — including R-7, R-10, R-15, and P-1 Planned Development districts that govern Dougherty Valley, Canyon Lakes, Twin Creeks, and Country Club areas — prohibit hoofed livestock. The nearest horse-keeping opportunities for San Ramon residents are in Alamo, Diablo, and unincorporated Contra Costa County portions of Blackhawk and Tassajara Valley, where agricultural zoning and minimum 2-acre lots allow horses. Some properties along the western edge of San Ramon near Las Trampas Regional Wilderness may have grandfathered agricultural uses, but new livestock operations require zoning variance and CEQA environmental review that are rarely granted in the built-out urban area. Backyard chickens are treated separately under a limited exemption (see chickens subcategory). Beekeeping is allowed with restrictions. Rabbits as pets (not meat production) are permitted. Honey bee hives are permitted with setback rules. Enforcement is complaint-driven through city Code Enforcement. Violations may result in abatement orders requiring removal of animals within 30-60 days, with progressive fines of $100/$200/$500 and daily penalties for continuing violations under Municipal Code Title A. California's Right to Farm Act (Civil Code §3482.5) protects pre-existing agricultural operations but does not authorize new livestock in urban zones. Residents seeking livestock lifestyle typically relocate to unincorporated county land or neighboring Alamo/Danville areas with larger lots.
