Land use in the unincorporated county is governed by Title 18 (Zoning) of the Napa County Code, adopted by the Board of Supervisors. The Napa County Planning Commission reviews and acts on projects such as use permits and variances and makes recommendations to the Board on rezonings and General Plan matters. The Planning Commission is regularly scheduled to meet on the first and third Wednesday of the month at the County Administration Building, 1195 Third Street, Napa. Cities within the county (including the City of Napa, Calistoga, St. Helena, American Canyon, and the Town of Yountville) administer their own separate zoning codes.
The AP (Agricultural Preserve) district, established under Chapter 18.16 of the Napa County Code, is applied to Napa Valley floor lands to preserve agriculture and agriculturally supportive uses. Under the Schedule of Zoning District Regulations (Section 18.104.010), the minimum lot area for the AP district is 40 acres. Agriculture is the primary permitted use, while uses such as wineries are allowed only upon the grant of a use permit under Section 18.16.030.
The AW (Agricultural Watershed) district, under Chapter 18.20 of the Napa County Code, is intended for areas that are agriculturally oriented and that include watershed areas, reservoirs, and floodplain tributaries where protecting agriculture, watersheds, and tributaries from fire, pollution, and erosion is essential to public health, safety, and welfare. The minimum lot size in the AW district is 160 acres, having been increased from an earlier 40-acre standard.
Yes. In Napa County's agricultural districts, a winery is allowed only upon the grant of a use permit. In 1990 the county adopted the Winery Definition Ordinance (WDO), which defines a winery as an agricultural processing facility for the fermenting and processing of grape juice into wine and sets conditions on winery operations. Among its provisions, for wineries first established after January 23, 1990, at least 75% of the grapes used to make the winery's still wine must be grown within Napa County.
Generally no. In 1990 Napa County voters passed Measure J, the Agricultural Lands Preservation Initiative, which requires voter approval to redesignate agricultural lands or to change the General Plan policies describing their intent, minimum parcel size, and maximum building intensity, subject to limited exceptions. In 2008 voters approved Measure P, which extended these protections through December 31, 2058.
