Louisiana Permit & Stamping Requirements

Code in effect in Louisiana

Louisiana enforces one statewide code, the Louisiana State Uniform Construction Code, and every local jurisdiction must enforce it. It is based on the 2021 International Building, Residential, Existing Building, Mechanical, Fuel Gas and Plumbing Codes, with Louisiana amendments, effective January 1, 2023 and amended most recently in March 2024. The 2021 International Energy Conservation Code is listed as current, and electrical work follows the 2020 National Electrical Code.

What to plan for

• ✓ The code is the same across the state, so parishes and cities enforce it but do not write their own building rules.
• ✓ The state Uniform Construction Code Council is working toward the 2024 editions and keeps amending the 2021 adoption in the meantime, so confirm the current amendments before drawings are issued.
• ✓ Coastal parishes face hurricane wind and flood exposure, so wind uplift and floor elevation often drive design there.
