In 2003, ICC created 12 Regions to encourage the formation of Regional Chapters. There are significant benefits for state and local chapters to participate at the region level. Regional chapters can create stronger more unified networks of building safety professionals, provide greater political strength when addressing code adoption and code development issues, and deal more effectively with state legislators. Upper Great Plains Region III holds a week long educational institute annually in Minnesota which attracts hundreds of code officials from the five state area. ICC Upper Great Plains Region III Bylaws
