Adoption model & precedence

  • The State Fire Commission adopts/administers both the State Building Code and State Fire Code — a structural difference from most states (which separate these).
  • Codes are statewide-mandatory; local jurisdictions enforce.
  • AHJ = local building department, applying the statewide edition.

AHJ fallback (when local adoption is unverified)

  • State baseline (certain): 2018 IBC/IRC/IMC/IPC, NEC 2020 (eff. 2022-08-01), IECC 2015 (dated).
  • Action: confirm no newer NEC/energy cycle has been adopted since this check — WV was confirmed still on NEC 2020 (not yet 2026 NEC) as of 2026-07-03.
