Regulatory framework
The code baseline for Lewis County.
City of Weston automatically adopts the current West Virginia State Building Code and its amendments: the active 2026 suite includes the 2018 IBC, IRC, IPC, IMC, IFGC, IPMC, IEBC, and International Swimming Pool and Spa Code; 2015 IECC; 2017 ICC/ANSI A117.1; 2020 National Electrical Code; and NFPA 101 Life Safety Code (2021), with state amendments. Lewis County separately provides county floodplain determinations outside the city.
