Building Codes in Louisiana

Building permit requirements in Louisiana are enforced at the local level, each city and county building department sets its own rules, fees, and timelines. Most cities in Louisiana follow the 2021 IRC, though 1 city is still on the 2021 Louisiana State Uniform Construction Code (LSUCC; based on 2021 IRC + LA amendments effective Feb 20, 2023) edition.

We cover 29 cities in Louisiana with 2,851 specific permit rules. That's real, locally researched data, not generic advice. Each city page shows exactly what triggers a permit, what's exempt, estimated fees, and how to apply.

The bottom line: don't assume your city follows the same rules as the one next door. A fence that's exempt in one town might need a full permit two miles away. Always check your specific city.

Permit Fees Across Louisiana
