Summary
Sonoma County shields properly conducted farms and ranches on agricultural land from nuisance lawsuits and requires sellers to disclose the Right to Farm Ordinance before selling property near ag operations.
No agricultural operation conducted or maintained on agricultural land in a manner consistent with proper and accepted customs and standards, as established and followed by similar agricultural operations in the county, shall be or become a nuisance for purposes of this code or county regulations if it was not a nuisance when it began, provided that such operation complies with the requirements of all applicable federal, state, and county statutes, ordinances, rules, regulations, approvals and permits.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 64 Update 2).
Full Breakdown
Sonoma County Code § 30-25 bars nuisance claims against a properly conducted agricultural operation on agricultural land that wasn't a nuisance when it began, covering noise, odors, dust, and machinery use at any hour, but only if the operation complies with all applicable laws and isn't run negligently. The ordinance applies only in the unincorporated county; land is 'adjacent' if within 300 feet of agricultural land. Anyone seeking a development approval on or near agricultural land must sign and record a Right to Farm declaration, and property sellers within 300 feet of agricultural land must disclose the ordinance under § 30-28.
Violations & Fines
Noncompliance doesn't void title or block recording (§ 30-29), but an operation that violates other laws or is run negligently loses the nuisance shield entirely.
