Plan Preparation: Prepare your plans, permit forms, and supplemental information (i.e engineering calculations, geotechnical report, etc) as per the Submittal Checklist, Codes and Design Criteria, and Electronic Plan Requirements
Plan Submittal: Plans can be submitted online via the electronic plan review process MIePlan.
Plan Review and Resubmittal of corrected plans: Your plans are reviewed for conformance with regulations pertaining to five separate disciplines: Tree review, Fire review, Land Use review, Civil review, and Building review. To reduce the overall processing time, separate comments from each plan review discipline are sent to you immediately after each review is completed. This provides you with the opportunity to coordinate and forward the City comments to your appropriate design team member as early as possible. However, you must coordinate your design team responses before resubmitting the plans.
Plan Approval/Permit Issuance: After the plan review comments have been adequately addressed, you will receive your permit. An approved copy of the plans must be maintained at the job site at all times.
Plan Review Target Times: Click here to access a page that shows the target time frame until your initial plan review is conducted (as determined from the date your application materials are approved at intake screening).
Plan Review Status: You can check your plan review status by going online at MyBuildingPermit.com or by calling Customer Service Team (CST) at the permit center at (206) 275-7605.
