Ontario Building Code Practice Exam

What is the minimum headroom required for a stairway in a residential building?

1. 1.8 meters

2. 2.0 meters

3. 2.2 meters

4. 2.4 meters

The correct answer is: 2.0 meters

The minimum headroom required for a stairway in a residential building is 2.0 meters. This requirement is necessary to ensure the safety and comfort of people using the stairway. Option A, 1.8 meters, is too low and could cause people to hit their heads. Option C, 2.2 meters, and Option D, 2.4 meters, are both higher than the minimum requirement, but may not be practical for all building designs and may add unnecessary construction costs. It is important to follow building codes and regulations to ensure the safety and functionality of stairways in residential buildings.
