An encroachment permit is needed to conduct activities in the “public right of way,” which is public property in unincorporated Sonoma County such as roadways, driveways, sidewalks, curbs, and gutters. You need an encroachment permit if any structure, object or improvement is placed or constructed in, under or over any public right of way.
Examples of activities that require an encroachment permit if conducted in the public right of way include
- posting signs
- roadway widening
- trenching and excavations
- placing mailboxes
- temporary placement of scaffolding
- dumpsters, storage bins or debris boxes.
The repair and installation of public utilities also requires an encroachment permit.

As of July 12, 2019, Permit Sonoma will be changing how fees are assessed for encroachment permit applications and septic permit applications to be more consistent with how we assess fees for other types of similar construction permit applications.
