Building code in Nunavut

Nunavut has adopted National Building Code of Canada 2015 (National Building Code of Canada (NBC)), effective September 1, 2018. The adopting authority is Government of Nunavut — Community and Government Services, Safety Services Division (Office of the Chief Building Official). Verified June 28, 2026.

Nunavut adopts the National Building Code of Canada 2015 (first printing, including revisions/errata before September 1, 2018) under the Building Code Regulations (R-009-2018, Building Code Act), with Nunavut-specific modifications in Schedule 1; adoption is explicitly static (not 'as amended from time to time'). Building HVAC/mechanical is covered within this code, not a standalone mechanical code. Nunavut follows the National Model Codes with a lag — it remains on the 2015 edition while NBC 2020 adoption is not yet in force. The 2024 amendment (R-016-2024) was an administrative name change only and did not bump the edition.

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.
