Code Adoption and Change Process

Code Change Process

Regulatory: Building codes for one- and two-family residential buildings are promulgated through the Louisiana State Uniform Code Council. Because the state adopts the International Residential Code (IRC), changes to the IRC are reviewed and recommended by an IRC review subcommittee, then a Technical Advisory Committee, then by the full Code Council. The final decisions of the Code Council are must then proceed through the state’s administrative rules review process before becoming law. Building codes for other residential buildings and all commercial buildings are developed by the State Fire Marshal’s office.

Code Change Cycle

The LSUCC for low-rise residential buildings was last updated January 1, 2015. The CBECC for all other buildings was last updated July 20, 2011.
