Similar to a legislative history for laws and statutes, this collection provides a comprehensive background on each change that occurred in the 2024 IBC, IRC, IFC, IPC, IMC, IFGC, IEBC and IECC including the original proposal, committee action, and final action documentation in a single source. The book compiles the proponent’s original reason for the change, unabridged statements that substantiated code development committee actions and the complete documentation for any public comment that was considered prior to final action on the change. This valuable collection greatly simplifies researching the history of a new, revised or deleted code section from 2021 to 2024 by showing all of the approved changes in legislative format helping the understanding, interpretation and intent of the 2024 I-Code provisions.
