Code Adoption and Change Process

Code Change Process

Updated codes are adopted every three years by the Idaho Legislature as they are revised by the International Code Council (ICC). Code amendments are adopted by the Idaho Building Code Board.

Code Change Cycle

Three-year code review cycle, concurrent with the publication of new editions of the model codes.

Next Code Update

Keeping with the historical three-year cycle, Idaho should adopt the 2015 IECC sometime in early 2018.
