Additional Information



    The 1976 edition of the Uniform Codes was adopted in 1977. Prior to 1977, the State Fire Marshal's Office adopted and enforced the National Fire Prevention Agency standards. Since 1977, the state has adopted the current version of the Uniform Building Code consistent with its three-year publication cycle. 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).

    Adoption Process

    Proposed changes to the state energy code may be submitted to the Wyoming Department of Fire Prevention and Electrical Safety (DFPES). The DFPES reviews proposed changes and submits its recommendations to the Governor-appointed Building Codes Council. Changes approved by the council are then adopted at the annual September meeting and become effective in January of the following year. Local adoption is required before energy provisions can be enforced.

    Enforcement Process

    Towns and counties that are established as local enforcement may, but are not required to, enforce an energy code at the local level. Currently, 20 towns and counties are established as local enforcement. As part of their normal building inspection process, the enforcement agency performs field inspections in these towns and counties. The DFPES has the authority to issue written interpretations.

    Compliance Process

    Compliance is determined by plan review and inspection by local code officials in jurisdictions that have adopted energy provisions as a part of their building code.
