💡 5 Tips to Speed Up Your Permit Approval

Save weeks of back-and-forth with these proven strategies used by experienced contractors.

1
Submit Complete Plans the First Time
Incomplete applications are the #1 cause of delays. Include site plans, floor plans, elevations, and structural drawings all at once. Missing a single sheet can add 2–4 weeks.
2
Call Before You Submit
A 10-minute pre-application call with the building department can save days. Ask: "What are the most common reasons for rejection?" They often give you the checklist for free.
3
Use a Licensed Contractor (They Know the System)
Contractors who regularly pull permits in Hennepin County know which reviewers to work with, what format is preferred, and common local code requirements. It's not just about the labor.
4
Check the Online Portal Daily
Most jurisdictions now post permit status online. When a "correction notice" is issued, respond within 48 hours. Permits that sit in the correction queue for 2+ weeks often get closed out.
5
Schedule Inspections Early & Group Them
Inspection slots fill up fast, especially in busy months. Book your framing, plumbing, and electrical rough-in inspections on the same day when possible to avoid multiple scheduling delays.
