Sonoma County is comprised of nine incorporated cities, and the unincorporated area governed by the County of Sonoma. Each jurisdiction is charged with regulating permits and ensuring compliance within its own boundaries. Various state agencies also regulate air quality, water quality, food safety, employee safety, energy efficiency, and the like.
