What you need to know today

The threat of injury from deadly carbon monoxide poisoning is reduced by requirements for the installation of alarms designed to detect low levels of the gas and alarm residents of the home before reaching levels that threaten health. Electrical distribution systems will be protected with the installation of arc-fault circuit interrupters reducing the chances of fires and protecting families’ futures and their investments for generations. Every basement will be required to have an escape and rescue opening, not only making the basement safer for the resident but also safer for firefighting personnel; and these are just a few measures benefiting Indiana residents in homes built under the new code requirements. Some of the other new requirements:

  • More robust garage separation 
  • Increased lot line fire separation 
  • Up-to-date seismic design categories 
  • Carbon monoxide detectors 
  • New anchor bolt requirements 
  • New section on deck construction 
  • Expanded wall bracing section New vapor retarder definitions and applications 
  • Uplift tables for roof structure attachment to top-of-wall 
  • New solar installation information 
  • Arc-resistant CSST recognized in code language .
