NEC edition in Utah

Utah has adopted 2023 NEC (NFPA 70) (NEC / NFPA 70), effective July 1, 2025. The adopting authority is Utah Division of Professional Licensing (DOPL) / Electricians and Plumbers Licensing Board; adopted by the Utah Legislature under Title 15A. Verified July 2, 2026.

Utah adopts the 2023 National Electrical Code statewide (Utah Code 15A-2-103) with statewide amendments (Title 15A, Chapter 3). The 2023 NEC took effect 2025-07-01; the prior statute version (effective 2024-07-01) still referenced the 2020 NEC. The NEC edition is unchanged by the 2026-07-01 construction-code update (HB65 keeps the 2023 NEC). Administered/licensed by DOPL and the Electricians and Plumbers Licensing Board.

It is the specific edition of a model code (for example the 2023 NEC, the 2021 IBC, or CSA C22.1:24) that a state or province has legally adopted and currently enforces. Codes are republished on roughly three-year cycles, and each jurisdiction adopts a new edition on its own schedule — often with amendments — so the edition in force varies by place and by discipline.

Not always. Many jurisdictions set a statewide or provincial baseline edition, but local building departments (the authority having jurisdiction, or AHJ) can amend it or enforce a different edition. Some states leave most adoption to local jurisdictions, and a few large cities such as Chicago and New York City run their own codes. Always confirm with your AHJ.

In the United States: the NEC (NFPA 70) for electrical, the ICC I-Codes (IBC/IRC) for building, the UPC (IAPMO) or IPC (ICC) for plumbing, the IMC/UMC for mechanical, the IFGC/NFPA 54 for fuel gas, and the IFC/NFPA 1 for fire. In Canada: the Canadian Electrical Code (CSA C22.1), the National Building, Plumbing and Fire Codes of Canada and their provincial editions, and CSA B149.1 for gas.

NFPA offers free read-only online access to many of its standards including the NEC, and the ICC publishes its I-Codes through a free online reading room. Canadian codes are typically published by CSA Group or the National Research Council and may require purchase or membership. Each result links to the official source.

Trade codes are copyrighted by their standards bodies (NFPA, ICC, IAPMO, CSA). This directory publishes only factual adoption data — which edition is in force, when it took effect, who the authority is, whether it is amended, and where to read it officially — and links you to the official source for the code text itself.
