The current building and fire codes that are applicable in Connecticut are based on the 2015 Editions of the International Code Council (ICC) documents. In 2020, the State was in the process of moving towards the next version of the codes based on the 2018 ICC documents; however, this was put on hold due to COVID-19. Two years later, they have shifted their original intent and are in the process of moving to the following codes, effective October 1, 2022:
- 2022 Connecticut State Building Code (CSBC)
- 2022 Connecticut State Fire Safety Code (CSFSC)
- 2022 Connecticut State Fire Prevention Code (CSFPC)
These codes will adopt and amend the following national standards:
- 2021 International Building Code (IBC) by the ICC
- 2021 International Existing Building Code (IEBC) by the ICC
- 2021 International Energy Conservation Code (IECC) by the ICC
- 2021 International Mechanical Code (IMC) by the ICC
- 2021 International Plumbing Code (IPC) by the ICC
- 2021 International Residential Code (IRC) by the ICC
- 2021 International Swimming Pool & Spa Code (ISPSC) by the ICC
- 2020 NFPA 70 National Electrical Code (NEC) by NFPA
- 2017 ICC A117.1 Accessible and Usable Buildings and Facilities by the ICC
- 2021 International Fire Code (IFC) by the ICC
- 2021 NFPA 101 – Life Safety Code by the NFPA
- 2021 NFPA 1 – Fire Code by the NFPA
Historically, a concurrency period has not been provided in CT when switching code editions without approval of a state modification. There have been discussions about offering one for this cycle, however, no formal word has been provided at this time.
