Ontario Building Code Practice Exam

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

1. 1.1 meters

2. 1.2 meters

3. 1.3 meters

4. 1.4 meters

The correct answer is: 1.2 meters

The minimum width required for a stairway in a commercial building is typically determined by local building codes and can vary between jurisdictions. However, the most common minimum width required is 1.2 meters. Option A is incorrect because 1.1 meters may be too narrow and pose a safety hazard for people using the stairs. Option C and D may exceed the minimum required width and would result in wasted space and higher construction costs. It is important to check with local authorities for specific requirements in your area.
