Adopting authority
Maine Fuel Board, Office of Professional and Occupational Regulation
Authority websiteFuel-gas (natural gas and propane) work is governed by NFPA 54 and NFPA 58 as adopted by the Maine Fuel Board (Title 32, Ch. 139) with Maine modifications. NFPA 58 is referenced at the 2020 edition; the in-force NFPA 54 edition year was not definitively confirmed from the official rule text, so confidence is reduced.
State/province adoption is the baseline. Your local building department may amend it or enforce a different edition — always confirm with the authority having jurisdiction (AHJ) before you design, bid or pull a permit.

Frequently asked questions
Which fuel gas code edition is in force in Maine?+
Maine has adopted NFPA 54 National Fuel Gas Code and NFPA 58 LP-Gas Code (2020) — exact NFPA 54 edition not definitively confirmed (NFPA 54 (National Fuel Gas Code)). The adopting authority is Maine Fuel Board, Office of Professional and Occupational Regulation. Verified June 28, 2026.
Does Maine amend the base code?+
Fuel-gas (natural gas and propane) work is governed by NFPA 54 and NFPA 58 as adopted by the Maine Fuel Board (Title 32, Ch. 139) with Maine modifications. NFPA 58 is referenced at the 2020 edition; the in-force NFPA 54 edition year was not definitively confirmed from the official rule text, so confidence is reduced.
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.
