Adoption model & precedence
- LSUCCC codes are statewide-mandatory; local jurisdictions enforce with limited amendment authority.
- Pipeline: 2023 NEC and 2024 ICC-family codes are currently under LSUCCC review — expect an update; confirm effective date before assuming 2020/2021-cycle values remain current for new permits at the time of use.
- AHJ = local building department, applying the statewide edition.
