How the Indianapolis Permit Review Process Works
Step 1: Application Submission
Submit your permit application through the Indianapolis 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.
