Ontario Building Code Practice Exam 2026 – All-in-One Guide to Master the Code!

In commercial buildings, the minimum height required for a ceiling is usually between 2.1 meters (around 7 feet) and 2.4 meters (around 8 feet). Although options B, C, and D may seem like feasible options, they are actually too high for a standard commercial building and would not meet building codes and regulations. Option A, 2.1 meters, is the closest to the minimum requirement and is therefore the correct answer. It is important to adhere to these building codes to ensure the safety and functionality of the commercial building.
