What Wyoming Construction Codes and Editions are Adopted:

According to the ICC, The Wyoming State Fire Marshal adopted the 2018 IBC, IFC, IMC, IFGC and IEBC. Provisions of the IRC and IPMC are also adopted by reference to the extent that those codes are referenced in the IBC, IFC, IMC and IFGC and contain fire and life-safety provisions.

Additionally, according to the NEC, as of July, 2020, Wyoming has adopted the 2020 National Electrical Code.

Finally, according Building Codes assistance project, Wyoming has not adopted a statewide energy code.

  • 2018 International Building Code (IBC)
  • 2018 International Existing Building code (IEBC)
  • 2018 International Mechanical Code (IMC)
  • 2018 International Plumbing Code (IPC)
  • 2018 International Fuel Gas Code (IFGC)
  • 2020 National Electrical Code (NEC)
  • 2018 International Fire Codes

Applicability (statewide, local, limited): LIMITED

Codes are primarily adopted and enforced locally. Wyoming statute 35-9-106 assigns authority to the Wyoming State Fire Marshal to establish minimum fire standards that are not to exceed the standards of the I-Codes for all new and existing buildings. Other Wyoming departments also have latitude to adopt codes as it pertains to the scope regulated within their department.

Wyoming does not have a mandatory statewide energy code.  Both residential and commercial building codes are voluntary. As a state, Wyoming’s codes are based on the 1989 Model Energy Code (MEC); however, some jurisdictions have chosen more stringent codes than what is suggested. However, the eight most populous jurisdictions in the state have advanced building codes in place, including the 2009 IECC and the 2012 IECC.

The current energy provisions are contained in Appendix Chapter 53 of the 1991 Uniform Building Code, which references the 1989 Council of American Building Officials (CABO) Model Energy Code (MEC). This code may be adopted and enforced by local jurisdictions.
