Quirks & watch-items
Quirks & watch-items
- Wyoming's State Fire Marshal handles BOTH building code adoption (IBC, IFC, IFGC, IMC, IEBC) AND electrical (NEC) — single agency consolidates state code authority.
- No statewide IRC** — residential code is purely local-option. Some jurisdictions (e.g., Teton County, Jackson) have adopted older IRC editions independently.
- No statewide IECC** — energy code is purely local-option. Jackson/Teton adopted IECC 2012; Cheyenne adopted IECC 2009 historically.
- All IBC/IFC/IFGC/IMC/IEBC moved together to the 2024 cycle on June 28, 2024 — synchronized adoption pattern.
- NEC moved to 2023 ahead of the 2024 building-code cycle (July 1, 2023).
