Summary
Riverside County's right-to-farm ordinance shields commercial farms on land zoned A-1, A-2, A-D, A-P, or C/V from nuisance suits once an operation has run for more than three years without complaint.
No agricultural activity, operation or facility, or appurtenances thereof, conducted or maintained for commercial purposes, and in a manner consistent with proper and accepted customs and standards, as established and followed by similar agricultural operations in the same locality, shall be or become a nuisance, private or public, due to any changed condition in or about, the locality, after the same has been in operation for more than three years if it was not a nuisance at the time it began.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 84 Update 1).
Full Breakdown
Chapter 5.40 bars nuisance liability, private or public, against a commercial agricultural activity, operation or facility on land zoned primarily for agriculture (A-1, A-P, A-2, A-D, or C/V) once it has operated more than three years without having been a nuisance when it began, so long as it follows customs and standards typical of similar local operations. The protection does not override state Health and Safety, Fish and Game, Food and Agricultural, or Water Code nuisance provisions, and it applies only in the unincorporated county: the 28 incorporated cities, including Riverside, Temecula, Hemet, and Murrieta, set their own rules.
Violations & Fines
A neighbor's nuisance claim against a qualifying, 3+ year commercial farm operation run to local agricultural standards is barred under this chapter; it does not excuse an operation that violates state health, water, or fish and game nuisance law, or one that was already a nuisance when it started.
