Steps to get a sign permit in Louisiana

Step 1: Measure the sign face area, height, and setback from property line
Step 2: Check the city's sign code — every city has size, height, illumination, and landmark district limits
Step 3: Get landlord written approval if you're a tenant
Step 4: Apply through the city's planning or building department with a scale drawing showing dimensions, materials, and mounting method
Step 5: Pay the sign permit fee (often based on sign area)
Step 6: Schedule the sign inspection after installation — the sign isn't legal until it passes
