Mendocino County, CA Right to Farm: Agricultural Zoning Protection (2026)

13 (Agricultural Nuisances and Consumer Disclosures), by Ord. No. 3414 in 1983 and amended it by Ord. No. 3463 the same year. Sec. 020 declares the county's policy to conserve and encourage agricultural production and bars any commercial agricultural operation, once it has run for more than three years without the action being a nuisance when it began, from being declared a private or public nuisance for neighboring land uses, unless the nuisance stems from negligent or improper operation. Sec. 052, and note that residential development next to those districts often pressures farm operations to curtail themselves.

To warn incoming residents, Sec. 040 requires anyone selling or leasing real property that is zoned Agricultural Land, or sits within 300 feet of Agricultural Land, to disclose in the sale or lease document that dust, smoke, noise, odor and agricultural chemicals are normal and expected. Sec. 040(C) goes further for construction: before Planning and Building Services can issue a building permit for a residence on or within 300 feet of Agricultural Land, the property owner must sign a statement acknowledging those same conditions, unless the disclosure already appears in a signed sale or lease document.

Sec. 050 lets the county post signs at the entrance to established farming areas warning buyers that producers' interests are legally protected, and Sec. 060 gives this chapter precedence over any conflicting county ordinance.
