Step 4 - Application Processing & On-Property Inspections  (8-10 weeks*)
Three different County departments get a copy of your application packet, and processes it independently of the other departments. Each department may conduct on-property inspections before or after permitting. You may be asked to provide additional reports, information, or to revise your plans based on County codes. 

  • The three departments are: Environmental Health., Development Review & Development Services. Each has expertise in different parts of County code.
  • Some inspections, like gophers, are only conducted certain times of the year. (Only about 12% of County applications require gopher inspections.)
  • Check the progress of your permit application:   Permit Checker   
  • *8-10 weeks is average. Times vary based on specific project. Large projects and those needing seasonal inspections may take longer. If the County asks for additional information or materials, allow additional processing time.
