When does a code continue to be law following the publication of a new edition?

A code continues to be law following the publication of a new edition until the Authority Having Jurisdiction (AHJ) adopts the updated edition. This principle is rooted in the fact that codes and standards are adopted at specific intervals, and until the AHJ officially incorporates the new edition into the applicable regulations or policies, the previous edition remains in effect.

This ensures stability and continuity for those who must comply with existing regulations while also allowing time for stakeholders, including local governments and fire departments, to review and prepare for the implementation of the new code. Without the formal adoption by the AHJ, the latest updates do not hold legal status, and the previous code continues to govern until officially changed.
