Significant Changes to the 2018 International Residential Code

Most one- and two-family dwellings are required by law to be constructed in compliance with state and local building codes and the standards referenced in those codes. Most jurisdictions that enforce a residential building code have adopted the International Residential Code® (IRC) developed by the International Code Council (ICC). This webinar replay highlights significant changes to the 2018 edition of the IRC, including the energy provisions of Chapter 11.

Participants in this webinar replay will:

  • Discuss significant changes to the 2018 edition of the International Residential Code®, including changes to the energy provisions of Chapter 11.
  • Examine which code changes may significantly affect construction in your region and the reasons behind those changes.
  • Gain insight into the basic code development process and how code changes are proposed and adopted for the IRC.
  • Review how codes are adopted and can be amended at the state or local level.
