Louisiana permits
Do you need a permit in Louisiana?
Louisiana enforces the Louisiana State Uniform Construction Code (IRC-based) statewide, with strict wind provisions and post-Katrina amendments. Parishes and municipalities handle permits. The State Licensing Board for Contractors requires a residential license for projects over $75,000 (and a home-improvement registration for $7,500-$75,000). Electrical and plumbing are state-licensed.

Can a homeowner pull the permit?
Yes, in most cases. Owner-occupied primary residences. Home-improvement registration/license applies to hired work above the thresholds.
Where to file: Parish or municipal permit office. New Orleans (One Stop), Baton Rouge, Lafayette have portals. Coastal/flood projects get elevation review. Plan review 1-3 weeks.
