Important: City vs. County Permit Authority
In Louisiana, properties located inside incorporated city limits are governed by municipal building departments. Properties in unincorporated areas fall under county building jurisdiction. Applying to the incorrect authority will delay your project and may forfeit plan review fees.
🛠️ Building Code Standards in Louisiana
