  • 2012 International Mechanical Code (IMC)
  • 2012 International Energy Conservation Code (IECC)
  • 2012 International Plumbing Code (IPC)

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 (2006 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 2009 IPC, IFGC and plumbing chapters of the 2009 IRC as the state minimum plumbing code.

City of Denver – In December 2019, the City of Denver voted to adopt the 2019 Denver Building Code, which includes the 2021 IBC tall mass timber code provisions. As part of the adoption of the new code, there will be a four-month period where new projects can use either the 2016 Denver Building Code or the newly-adopted 2019 version. After four months, all building, and fire code permits will be processed under the 2019 Denver Building Code.
