Adoption Process for the 2018 State Building and Fire Safety Codes:

The State Building Inspector, State Fire Marshal and the Codes and Standards Committee announced on December 29, 2016 intent to adopt the 2018 State Building and Fire Safety Codes based largely on the 2015 editions of the International Code Council (ICC) and National Fire Protection Association (NFPA) documents (see below).  

Technical review of these codes was conducted by the Committee’s Codes Amendment Subcommittee (CAS) along with DAS staff.  Workgroups made up of CAS members and DAS staff, were established to review specific portions of the proposed codes for changes from the current code and to update the current amendment documents. Each of these workgroups provided a report of their review, identified issues that required additional discussion or research, and presented their amendment document changes. The schedule of these reports can be found in the CAS meeting schedule under "what's next". 

This review began January 2017 and was completed with the Codes and Standards Committee’s approval for DAS to move both codes the legislative approval process at its November 8, 2017 meeting. The agency then accepted comments from the public (see below) for a period of forty-five (45) days, beginning January 2, 2018 through the close of business February 16, 2018.

The revised draft codes were submitted to the Legislative Regulation Review Committee on May 2, 2018.  At the Committee’s May 24th meeting all three codes were rejected without prejudice, based on the recommendation of the Legislative Commissioners Office (LCO) reports.  Responses to comments in these reports and revised codes were submitted to the Committee on June 21, 2018 for reconsideration and were approved on July 24, 2018.
