Santa Barbara County, CA Right to Farm: Agricultural Zoning Protection (2026)

Santa Barbara County Code Sec. 3-23 shields commercial agricultural operations on land the Comprehensive Plan designates AG-I or AG-II, or land zoned exclusively for agricultural use, from nuisance lawsuits filed by neighbors over the sounds, odors, dust, and chemicals that come with farming. The protection kicks in once an operation has run for more than three years without being a nuisance when it started, and only if the operation follows the customs and standards used by similar agricultural operations in the same locality. The Board of Supervisors adopted the finding that residential development next to farmland often pressures farm operators into restrictions that hurt the county's agricultural economy, so the ordinance is meant to warn incoming residents, not to give farms a blank check.

The County's Resource Management Department is required to publish a standard public-information notice telling nearby property owners, renters, and lessees that they may face inconvenience from cultivation, tilling, pesticide and fertilizer application, irrigation, pruning, harvesting, and processing of crops, livestock, poultry, and timber. Cannabis cultivation and cannabis operations are expressly carved out of Sec. 3-23's protection because state and county cannabis rules already impose their own development standards. On the zoning side, County LUDC Sec. 020 sets the purposes behind the two agricultural zones this right-to-farm law rides on: the AG-I zone applies in Urban, Inner Rural, and Existing Developed Rural Neighborhood areas to keep agriculture viable, while AG-II applies to prime and non-prime agricultural land in the Rural Area specifically to preserve it for long-term farming. This is a county provision reaching only the unincorporated area; Santa Barbara, Santa Maria, Lompoc, Goleta, Carpinteria, and Buellton run their own codes.
