Ontario Building Code Practice Exam

In the context of commercial buildings, the minimum clearance for a door is typically set at 800 mm. This value is essential to ensure that the door can accommodate accessibility requirements, allowing sufficient space for all individuals, including those using mobility aids such as wheelchairs or walkers. The 800 mm clearance facilitates easier passage and is aligned with the goals of promoting accessibility in building design.

This standard is established in line with accessibility regulations and is intended to provide both safety and convenience for users. A door that is at least 800 mm wide ensures that it can be effectively used in a commercial setting where foot traffic may be heavier, and where universal access is part of the operational requirements. This is especially important in public spaces, where compliance with building codes directly relates to user safety and accessibility standards.
