Brentwood FAQ
Can I keep a horse on a half-acre Brentwood lot?
Sometimes. Half-acre (~21,780 sq ft) lots may qualify in certain rural residential zones with proper setbacks and corral/barn permitting. Check with Brentwood Planning to confirm your parcel's zoning and lot standards.
Can a new neighbor force my orchard to stop spraying?
No. California's Right to Farm Act (Civil Code §3482.5) protects established agricultural operations from nuisance claims by residents who moved in after the ag use was established, as long as the operation follows state pesticide and air quality rules.
