✅ The 5-Step Permit Application Roadmap

Never started a home project before? Follow this standard timeline to ensure your construction is legal, safe, and up to code.

Step 1

Check Local Zoning

Verify property lines, setbacks, and HOA rules before drafting plans to avoid immediate rejection.

Step 2

Draft Site Plans

Prepare architectural drawings or basic sketches depending on project scope. Commercial projects require stamped engineer plans.

Step 3

Submit & Pay

File your application via the county portal and pay the initial plan review fee. Wait times vary from 3 days to 4 weeks.

Step 4

Post the Permit

Once approved, print and display the physical permit card visibly on your job site (usually in a front window).

Step 5

Pass Inspections

Schedule mandatory county walkthroughs at specific milestones (framing, rough electrical, final completion).

⚠️ The Dangers of Unpermitted Work: Skipping the permit process can result in the county forcing you to tear down the completed work at your own expense. Furthermore, homeowners insurance often denies claims for fires or floods caused by unpermitted electrical or plumbing work.
