The Napa County Board of Supervisors is the primary governing body responsible for legislative and executive functions within the county. Comprised of five members, each elected by residents of one of five districts, the Board enacts laws, manages budgets, creates programs, appoints officials, and oversees land use and zoning in unincorporated areas. Board members serve four-year terms, with no limit on the number of terms, and the Chair of the Board is rotated among the districts. While the Board’s jurisdiction over municipal services like land use and roads is limited to unincorporated areas, its authority extends countywide for services such as Corrections, Health and Human Services, and document recording.
