Yes, Wyoming is a Home Rule jurisdiction. This means building code adoption and enforcement are primarily managed at the local level (city or county) rather than by a single state agency.

Most states, including Wyoming, review and adopt new building code editions every 3 to 6 years, typically following the triennial publication cycles of the ICC and NFPA.

Wyoming's current building code adoption is based on the 2024 edition cycle. Check the code cards above for specific edition years for each code type (IBC, IRC, IFC, etc.).

Wyoming allows local jurisdictions to adopt their own amendments. The amendment type for each code is indicated by the badge (As Is, State Amended, or State Edition) on each code card above.

Permit requirements in Wyoming depend on the locally adopted building codes shown above. Contact your local building department for specific permit thresholds and submittal requirements. The code edition in effect on your permit application date determines which requirements apply to your project.
