Summary

The California Right to Farm Act under Civil Code 3482.5 protects established agricultural operations from nuisance lawsuits brought by neighbors who moved in after farming began. The law applies statewide and limits both private and local government nuisance actions.

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 it has been in operation for more than three years if it was not a nuisance at the time it began.

Full Breakdown

Civil Code 3482.5 provides that no agricultural activity, operation, or facility conducted on agricultural land for commercial purposes shall be considered a nuisance, private or public, after it has been in operation for more than three years if the operation was not a nuisance at its inception. The protection extends against changed surrounding conditions, including new residential development encroaching on farm areas. The statute applies statewide and binds counties, cities, and private parties. Local nuisance ordinances cannot override the state's three-year farming protection. Operations conducted negligently or in violation of state or federal law lose protection.

Violations & Penalties

Qualifying farms can have barred nuisance actions dismissed under Civil Code 3482.5. Protection is lost for negligent or unlawful operations, and the statute does not shield activity that obstructs public waterways or roads.

Frequently Asked Questions

Does California's Right to Farm Act cover all farming operations?
It covers commercial agricultural operations on agricultural land that have operated more than three years and were not a nuisance at inception. Negligent or unlawful operations are excluded.
Can a California city declare a farm a nuisance?
Generally no. Civil Code 3482.5 preempts municipal nuisance actions against qualifying farms when they pre-date surrounding development by at least three years.
