Ontario Building Code Practice Exam

What is the maximum allowable height for a deck in a residential building?

1. 1.0 meter

2. 1.5 meters

3. 2.0 meters

4. 2.5 meters

The correct answer is: 1.5 meters

A 1.0 meter may be too low for a typical deck, as it would not provide enough space for people to stand comfortably underneath it. B: This is the correct answer. 1.5 meters is often considered the maximum allowable height for a deck in a residential building, as it allows for enough head clearance and meets most building codes. C: 2.0 meters may be too high for a deck since it could obstruct the view from the building and may require additional supports or railings that could increase the cost and complexity of the project. D: 2.5 meters is significantly higher than the standard ceiling height of most rooms, making it impractical and costly to build a deck at this height. It could also potentially block windows or interfere with the structure of the building.
