California Civil Code §3482.5 shields established agricultural operations from nuisance suits after three years of consistent activity. San Jose applies the state rule; the city has no separate right-to-farm ordinance beyond zoning.
California Civil Code §3482.5 provides that an agricultural activity in operation for more than three years and consistent with proper customs is not a nuisance because of changed surrounding conditions. Once a residential neighbor moves near an established farm, they cannot sue to shut it down for ordinary noise, dust, or odor. The protection applies to commercial farms, ranches, apiaries, and agricultural processing. San Jose has limited active agriculture today, mostly in Coyote Valley and parts of Almaden, plus permitted urban farms citywide. The city has no separate right-to-farm ordinance, so the state statute controls.
No fines apply to farms protected by Civil Code §3482.5. A neighbor who sues a protected farm and loses may owe defense costs. Operations exceeding proper customs forfeit the shield and face standard nuisance liability.
