STEP 2:   Prepare your Application Packet (Times vary) 

Instructions are on each application. Gather required information. Prepare necessary plans and drawings.

STEP 4:   Application Reviews & On-property Inspections  (8-10 weeks*)

Three County departments separately review applications, plans and drawings. Staff members from 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. 

  • Environmental Health Dept., Development Review Dept. & Development Services Dept. all review applications. Each has expertise in different parts of County code.
  • Each department gets a copy of your packet, and starts to work. 
  • Each department may conduct on-property inspections based on code requirements. Some inspections, like gophers, are seasonal.
  • 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.
