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

  • landscaping
  • fencing
  • 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.
