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

Once adopted, there is usually an announcement of an effective date, giving builders and developers time to adjust to the new regulations. This period between adoption and enforcement allows for training, dissemination of information, and completion of ongoing projects under the old codes.

Next Code Update

The International Code Council (ICC) publishes updates to the I-Codes on a three-year cycle. The most recent edition would be the 2021 I-Codes, as the 2018 codes were the last ones published before this. The LSUCCC typically begins reviewing these updates once published.
