WHERE TO OBTAIN THE 2018 STATE BUILDING CODE

The Office of the State Building Inspector announces adoption of the 2018 State Building Code with an effective date of October 1, 2018.

The documents that comprise the 2018 State Building Code are as follows:

  • 2015 International Building Code
  • 2009 ICC/ANSI A117.1 Accessible and Usable Buildings and Facilities
  • 2015 International Existing Building Code
  • 2015 International Plumbing Code
  • 2015 International Mechanical Code
  • 2015 International Energy Conservation Code
