Building code in Prince Edward Island

Prince Edward Island has adopted 2020 (National Building Code of Canada (NBC)), effective March 31, 2024. The adopting authority is Government of Prince Edward Island — Building Codes Act (Housing, Land and Communities). Verified June 28, 2026.

PEI Building Codes Regulations (under the Building Codes Act) adopt the National Building Code of Canada 2020 and the National Energy Code of Canada for Buildings 2020 (Energy Performance Tier 1), including revisions, with PEI-specific modifications set out in the Schedules; effective March 31, 2024. The Building Codes Regulations adopt only the building and energy codes (not the plumbing or fire codes).

It is the specific edition of a model code (for example CSA C22.1:24 or the 2020 National Building Code) that a 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 baseline edition for the whole province, but local building departments (the authority having jurisdiction, or AHJ) can amend it or enforce a different edition. Some places leave most adoption to local jurisdictions, and a few large cities run their own codes. Always confirm with your AHJ.

The Canadian Electrical Code (CSA C22.1) for electrical, the National Building, Plumbing and Fire Codes of Canada and their provincial editions for building, plumbing and fire, and CSA B149.1 for gas.

The National Research Council publishes the national model codes — building, plumbing, fire and energy — as free downloads. CSA standards such as the Canadian Electrical Code and CSA B149.1 usually have to be bought, though some provinces give free read-only access through their own portals. Each result links to the official source.

Trade codes are copyrighted by their standards bodies (CSA Group and the National Research Council of Canada). 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.
