International Code Adoption by State

The International Codes, or I-Codes, are developed and published by the International Code Council (ICC).  The I-Codes are adopted by all fifty states, the District of Columbia, and several countries.  Each state decides at what level, e.g., state or jurisdiction (municipality, city, etc.), codes are adopted.  Additionally, the code year adopted and the authority for introducing local amendments varies.  The jurisdictions responsible, at whatever level, have to manage code adoption and implementation.  While government entities are focused on their specific jurisdiction and thus familiar with their building code status, it can be difficult for designers who work across jurisdictions to identify the codes in use and where to access them, especially where local amendments are in place.

With this in mind, this page has been created to provide a quick reference to the code year currently adopted by each state for the International Building Code (IBC) and International Residential Code (IRC).  An “X” designation in the table below denotes those states where a specific IBC and or IRC code year has not been adopted and decisions are made at a local level.

Each state link leads to a brief overview of the current building (IBC) and residential (IRC) codes being used (and in most cases links to view the codes online for free) and other useful and interesting information, including links to information on the corresponding version(s) of Plan Analyst.  A sample of organizations who have used Plan Analyst within a state are provided to show that both building officials and architects/designers can benefit equally from the significant time savings the software delivers from automating the code study / plan review process.
