(a) (1) 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.
(2) No activity of a district agricultural association that is operated in compliance with Division 3 (commencing with Section 3001) of the Food and Agricultural Code, shall be or become a private or public nuisance 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. This paragraph shall not apply to any activities of the 52nd District Agricultural Association that are conducted on the grounds of the California Exposition and State Fair, nor to any public nuisance action brought by a city, county, or city and county alleging that the activities, operations, or conditions of a district agricultural association have substantially changed after more than three years from the time that the activities, operations, or conditions began.
(b) Paragraph (1) of subdivision (a) shall not apply if the agricultural activity, operation, or facility, or appurtenances thereof obstruct the free passage or use, in the customary manner, of any navigable lake, river, bay, stream, canal, or basin, or any public park, square, street, or highway.
(c) Paragraph (1) of subdivision (a) shall not invalidate any provision contained in the Health and Safety Code, Fish and Game Code, Food and Agricultural Code, or Division 7 (commencing with Section 13000) of the Water Code, if the agricultural activity, operation, or facility, or appurtenances thereof constitute a nuisance, public or private, as specifically defined or described in any of those provisions.
(d) This section shall prevail over any contrary provision of any ordinance or regulation of any city, county, city and county, or other political subdivision of the state. However, nothing in this section shall preclude a city, county, city and county, or other political subdivision of this state, acting within its constitutional or statutory authority and not in conflict with other provisions of state law, from adopting an ordinance that allows notification to a prospective homeowner that the dwelling is in close proximity to an agricultural activity, operation, facility, or appurtenances thereof and is subject to the provisions of this section consistent with Section 1102.6a.
(e) For purposes of this section, the term “agricultural activity, operation, or facility, or appurtenances thereof” shall include, but not be limited to, the cultivation and tillage of the soil, dairying, the production, cultivation, growing, and harvesting of any agricultural commodity including timber, viticulture, apiculture, or horticulture, the raising of livestock, fur bearing animals, fish, or poultry, and any practices performed by a farmer or on a farm as incident to or in conjunction with those farming operations, including preparation for market, delivery to storage or to market, or delivery to carriers for transportation to market.
