Wyoming Building Energy Codes

Wyoming does not have a statewide energy code. The Wyoming State Fire Marshall is the political body that is responsible for recommending to state legislature the adoption of statewide building codes in Wyoming. In May 2018, the 2018 International Building Code (IBC) was adopted but a few of the codes that the IBC references were amended out, including the International Residential Code (IRC) and International Energy Conservation Code (IECC). Of the 123 local jurisdictions in Wyoming, some have voluntarily adopted more stringent codes for the welfare of their communities, including Cheyenne and Gillette on the 2018 IECC and Jackson, Sheridan, and Rock Springs on the 2015 IECC.
