Building permit review in Dearborn, MI takes approximately 10 days for initial plan review. Here is what you need to know about permit timelines, costs, and the review process in Dearborn.
Dearborn Plan Review Timeline
Review times for the first submittal typically range between 5–10 business days, but may take longer depending on the complexity of the review, detail of the provided plans, time of year, or how busy the department is. The plan reviewer will contact the applicant throughout the process. If additional information or corrections are needed, a report detailing required changes is sent to the applicant, and plans will need to be resubmitted. The review process for resubmittals is not specified in terms of time frames, though the process repeats for each submittal until all requirements are met.
No explicit time frame is given for subsequent (revised) submittals, but the process is iterative and involves re-review by all relevant departments if changes are made. Projects with more complexity will require longer examination times. Additional factors affecting review time include the need for input from multiple departments and the quality of the submitted plans.

How the Dearborn Permit Review Process Works
Step 1: Application Submission
Submit your permit application through the Dearborn building department. Applications are reviewed for completeness before being assigned to a plan reviewer.
Step 2: Plan Review
The city reviews your submitted plans for building code compliance, structural integrity, fire safety, energy code, and ADA accessibility. Commercial projects are reviewed by multiple departments at the same time.
Step 3: Corrections and Resubmittal
If the city issues correction comments, you will need to revise your plans and resubmit. Each correction cycle adds another review period. Most commercial projects go through 2 to 3 correction cycles.
Step 4: Permit Issuance
Once all review departments approve your plans, the building permit is issued. Schedule inspections as work progresses.
