Administrative Office Districts

Administrative office districts, hereinafter designated as C-O districts, are established to provide for the location of offices for professional services and for business activities which are characterized by a low volume of direct consumer contact; and to encourage such development in a manner compatible with the uses in adjacent districts, with suitable open spaces, landscaping, and parking area. In Castro Valley (areas within the Castro Valley Urbanized Area), this also includes retail, service, and small scale production uses. C-O districts are typically situated in areas having convenient access from, but not directly on, main thoroughfares, and generally adjacent to a multiple residential development.
