Steps to pull a building permit in Kentucky

Step 1: Confirm the work needs a permit (in most cities: structural changes, new electrical circuits, plumbing changes, water heaters, roofs; NOT paint, flooring, minor drywall)
Step 2: Submit stamped plans (an engineer or architect stamp is required for structural work in most cities)
Step 3: Pay the plan check fee (a percentage of estimated project value)
Step 4: Wait for plan review — timeline varies enormously by city (3 days in small towns, 90+ days in San Francisco)
Step 5: Pull the permit and pay the permit fee once approved
Step 6: Schedule required inspections at each phase (foundation, framing, rough, final)
Step 7: Get final inspection sign-off — many cities won't refund your deposit or close the permit without it

Heads up: A common Kentucky mistake: assuming this building permit covers your city and county requirements too. It usually doesn't. Check your city's business division separately — most cities in Kentucky require their own general business license on top of state filings.
