International Code Adoption by State

The International Building Code and International Residential Code are a part of the I-Codes and are created by the International Code Council. They are updated and published on a 3-year cycle.  As model codes, local codes need to adopt the code for each jurisdiction.

The codes are designed for the protections of public health, safety and welfare.  The current version of the code is 2018.
