International Code Council

The International Code Council (ICC) is an American nonprofit standards organization sponsored by the building trades, which was founded in 1994 through the merger of three regional model code organizations in the American construction industry. Since 2023, ICC's headquarters has been based at Capitol Crossing in Washington, D.C. The organization creates the International Building Code (IBC) and International Residential Code (IRC), two model building codes, which have been adopted for use as a base code standard by most jurisdictions in the United States.
