Area ID

The county is divided into geographic areas for the purposes of various types of inspections that Permit Sonoma staff performs. These areas are named for communities, but are not necessarily contiguous with any individual community boundary due to aggregation of several communities into the larger area.

These areas are called Area IDs and are appended to the address attached to a permit. Three character IDs indicate unincorporated areas and two character IDs are incorporated cities.
