Ontario Building Code Practice Exam 2026 – All-in-One Guide to Master the Code!

The minimum height requirement for a handrail on a ramp in a residential building is essential for ensuring safety and accessibility. According to the Ontario Building Code, handrails must be installed at a height that provides adequate support for users, particularly those with mobility challenges. The specified height range of 865mm to 965mm is designed to accommodate different user needs, ensuring that individuals can easily grasp the handrail while navigating the ramp.

This height range reflects a balance between safety and usability, allowing a wide variety of people, including children and adults of varying heights, to use the handrail comfortably. It is crucial to comply with these regulations to provide safer environments in residential settings, thereby minimizing the risk of falls and injuries on ramps.

In contrast, other height measurements such as 850 mm, 950 mm, or 1050 mm do not meet the full range specified by the code. For instance, while 950 mm falls within the acceptable limits, it does not capture the complete mandatory range which ensures that flexibility is provided for different user requirements. Heights lower than 865 mm or higher than 965 mm could compromise the safety standards intended for handrails in these situations.
