State Adoptions
Codes are primarily adopted and enforced locally. Two state agencies adopt state minimum plumbing and electrical codes respectively. The State Architect adopts codes for all state-owned buildings and facilities (2012 IBC, IMC, IPC, IFGC, IECC). The Division of Fire Prevention and Control adopts and enforces codes for all public schools and junior colleges (2015 IBC, IRC, IFC, IMC, IEBC, IECC) and for all licensed healthcare facilities statewide (2012 IBC, IRC, IFC, IMC, IECC, IEBC, IWUIC). The Colorado Examining Board of Plumbers has adopted the 2015 IPC, IFGC and plumbing chapters of the 2015 IRC as the state minimum plumbing code.
