Substitute House Bill No. 5401, also known as Public Act No. 26-58, revises the State Building Code, State Fire Prevention Code, and Fire Safety Code in Connecticut. The bill mandates that the State Building Inspector and the Codes and Standards Committee, with the approval of the Commissioner of Administrative Services, adopt and administer a State Building Code based on a nationally recognized model building code. Key changes include the replacement of the term "code" with "State Building Code" and the extension of the timeline for incorporating revisions to the code from eighteen months to two years after the first publication of updates to the nationally recognized model building code. Additionally, the bill emphasizes the importance of energy conservation and the inclusion of electric vehicle charging capabilities in new residential garages.

Similarly, the State Fire Prevention Code and Fire Safety Code will also undergo revisions, with the term "code" replaced by "State Fire Prevention Code" and "Fire Safety Code," respectively. The timeline for incorporating updates to these codes is also extended to two years, with specific provisions ensuring that no revisions are required after the first publication of the 2024 codes until the 2030 codes are published. The bill further mandates a report by the Commissioner of Administrative Services by January 1, 2029, assessing the impact of these changes and providing recommendations for future amendments to the revision cycles of the codes.
