  • The Permit History provided may not include all records for this property. Further investigation may be required to obtain a more complete history due to: address changes, parcel mergers, splits, retirements, etc.
  • Date(s) listed in this report reflect the earliest known date(s) associated with each file. The date(s) listed are not associated with the current status.
  • Permit Status Definitions have been modified through time to better identify milestones during the life span of a specific File Type. Many historical files reflect statuses which are no longer in use.
  • Although every reasonable effort is made to provide complete and accurate information on this website, visitors are advised to contact appropriate Permit Sonoma staff before making project decisions. This may involve contacting more than one section within Permit Sonoma (Building Inspection, Plan Check, Planning (Zoning), Well & Septic, etc.) since each section implements specific codes or ordinances which may affect your project.
