Brentwood's agricultural heritage is reflected in the Municipal Code: livestock including horses, cattle, sheep, and goats are permitted on parcels zoned A (Agricultural) and in residential zones meeting minimum lot size and setback requirements. Right-to-Farm protections under California Civil Code §3482.5 apply to established ag operations.
Brentwood is known as the "City of Agriculture" and retains extensive agricultural zoning reflecting its orchard and farming heritage. Under BMC Title 17 (Zoning), large livestock (horses, cattle, sheep, goats, llamas) is permitted by right on parcels zoned A-20, A-40, A-80 (Agricultural) and on residential acreage parcels meeting minimum lot-size requirements, typically 20,000 sq ft or larger. Small livestock (hens, rabbits) is permitted in most residential zones within limits. Setbacks for livestock confinement and manure storage typically require 50 feet from habitable structures on neighboring properties. Feed storage must be rodent-resistant. Brentwood's established agricultural operations are protected by California Civil Code §3482.5 (Right to Farm), meaning new residents near orchards or ranches cannot successfully sue operators for noise, dust, or odor that was pre-existing. The Contra Costa County Agricultural Commissioner regulates pesticide use, and the East Contra Costa Fire Protection District (ECCFPD) enforces agricultural fire-safety requirements.
