Frequently asked questions
Which plumbing code edition is in force in Utah?+
Utah has adopted 2021 IPC (IPC (ICC)), effective July 1, 2023. The adopting authority is Utah Division of Professional Licensing (DOPL) / Uniform Building Code Commission; adopted by the Utah Legislature under Title 15A. Verified July 2, 2026.
Does Utah amend the base code?+
Utah is an IPC (ICC) state, not a UPC state. Adopts the 2021 International Plumbing Code statewide (Utah Code 15A-2-103) with statewide amendments (Title 15A, Chapter 3). A statutory update (HB65, 2026 General Session) is effective 2026-07-01 that moves the IPC to the 2024 edition.
What does "edition in force" mean?+
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.
Does the whole state or province use the same code?+
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.
Which model codes does this directory track?+
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.
How do I read the official code for free?+
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.
Why does this directory not show the actual code text?+
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.
