Ontario Building Code Practice Exam

The requirement for an accessible route in a residential building emphasizes the importance of ensuring safe and convenient access for individuals with disabilities. Among the provided options, having a minimum width of 0.9 meters is indeed essential for accessibility, as it allows sufficient space for individuals using wheelchairs or mobility aids to pass through comfortably.

However, to clarify, while the width of 0.9 meters is a standard guideline for accessibility, the actual minimum width required in Ontario’s Building Code may vary depending on the specific context and details of the building, such as the number of users or the type of access required.

The other choices highlight critical aspects of an accessible route: ramps with handrails provide support for people who may need help navigating slopes, level landings at changes of direction improve safety and usability by allowing individuals to navigate without the risk of falling, and a non-slip surface is essential to prevent accidents, especially in wet or icy conditions. Each of these factors contributes to a safer and more functional environment for users, reinforcing the overall goal of accessibility in residential buildings.
