Ontario Building Code Practice Exam

What is the minimum number of exits required for a residential building with a capacity of 20 people?

1. 1

2. 2

3. 3

4. 4

The correct answer is: 1

For a residential building with a capacity of 20 people, the minimum number of exits required is one. This is because according to most building codes, a single exit is sufficient for a residential building with a small occupancy load like this. Choice B, C, and D are incorrect because having two, three, or four exits would be excessive and unnecessary for this size of a residential building. It is important to note that building codes and regulations may vary by location, so it is always best to check the specific requirements for your area.
