Understanding NBC 2025 Handrail Requirements
Handrails are a fundamental safety component in any building project. As the 2025 National Building Code (NBC) updates take effect, empcontracting.ca Inc. your construction contractor in London, Ontario ensures all installations meet the rigorous new standards for safety and accessibility.
Handrail Height Standards
According to the NBC 2025, handrails must be installed at a height between 865 mm and 1070 mm. This measurement is taken vertically from the floor surface or the line drawn through the outer edge of the stair nosings. For stairs serving as required exits, these dimensions are critical to ensure a consistent grip for users of all heights and abilities.
Handrail Continuity and Extensions
Continuity is a vital aspect of the code designed to prevent falls. A handrail must be continuous throughout the length of the flight of stairs, including at landings. Where a handrail is interrupted by newel posts at changes in direction, the gap must be minimized to maintain a consistent guide for the user. Additionally, modern standards often require handrails to extend horizontally at least 300 mm beyond the top and bottom of the stairs to provide support before the transition begins.
Graspability and Wall Clearances
The NBC 2025 specifies that handrails must be easily graspable. This generally requires a circular cross-section with an outside diameter between 30 mm and 50 mm, or a non-circular shape with a similar perimeter. A minimum clearance of 50 mm between the handrail and the wall surface is mandatory to allow for an unobstructed grip, especially in emergency egress situations.
