Thank you for visiting the Local Agency Formation Commission (LAFCO) of Napa County’s website; the governmental agency designated by the California Legislature to manage local governmental boundaries, evaluate municipal services, and protect prime agriculture lands.  Everything you need to understand and work with LAFCO is available on this website.  This includes downloading application materials, viewing staff reports and studies, and identifying helpful resources relating to growth management in Napa County as well as for entire San Francisco Bay Area region. You are also welcome to contact us with any comments or questions by visiting the about us page.

Who uses LAFCO?
  • Individual home owners requesting annexation to a sewer district due to a failing septic tank.
  • Developers seeking annexation to cities in order to obtain more favorable development and urban services extended to the new housing.
  • Cities wishing to annex pockets or "islands" of unincorporated land located within their borders in order to avoid duplication of services with the county.
  • Special Districts or cities seeking to consolidate two or more governmental agencies into one, thereby streamlining their services and reducing the cost to local taxpayers.
