Ontario Building Code Practice Exam

What is the minimum width required for a corridor in a commercial building?

1. 1.2 meters

2. 1.5 meters

3. 1.8 meters

4. 2.1 meters

The correct answer is: 1.5 meters

A width of 1.5 meters is the minimum requirement for a corridor in a commercial building. This is based on safety regulations and accessibility guidelines. Option A (1.2 meters) is too narrow and could pose a hazard for people passing through, especially during an emergency situation. Option C (1.8 meters) and D (2.1 meters) exceed the minimum requirement and may not be cost-effective for the building design and construction. Overall, the 1.5 meter width provides a balance between safety and practicality.
