Summary
Under County Code Section 5.16.030, an agricultural operation run for commercial purposes and consistent with accepted local farming customs cannot become a public or private nuisance because of a changed condition nearby, once it has operated more than three years without being a nuisance when it began.
5.16.030 - Preexisting agricultural operations not a nuisance. (a) 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. (b) Subsection (a) of this section 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.
Full Breakdown
010 to include tillage, dairying, growing and harvesting any commodity including timber, viticulture, apiculture or horticulture, raising livestock, furbearing animals, fish or poultry, and related farm-market preparation. To qualify, the operation must be conducted for commercial purposes, follow customs and standards accepted by similar operations in the same locality, have run more than three years, and not have been a nuisance when it began; the protection then holds even if surrounding conditions later change. Subsection (b) removes the shield where the operation blocks free passage or use of a navigable lake, river, bay, stream, canal or basin, or a public park, square, street or highway.
031, extends the same three-year not-a-nuisance protection to agricultural processing uses (canning, freezing, dairy processing, beer and wine production, meat and egg processing, fruit and grain drying, and licensed rendering or collection centers), but allows a nuisance action against increases in processing activity after January 1, 1993, that significantly affect the environment, with a rebuttable presumption that a three-year-old increase was not substantial.
Violations & Fines
Section 5.16.030 itself creates a defense, not a penalty; a farm that fits its terms is immune from being declared a nuisance in county code enforcement and, per the disclosure findings in Section 5.16.040, cannot be forced to shut down or curtail operations solely because a new neighbor complains. Chapter 5.16's own penalty section, 5.16.080, classifies any violation of the chapter's requirements as a civil matter between the parties, not a misdemeanor or infraction.
