At what height does a building become classified as high-rise?

A building is classified as a high-rise based on its height, which has significant implications for safety regulations, fire protection measures, and structural requirements. The commonly accepted threshold for a building to be classified as high-rise is 45 meters. This distinction is important because buildings exceeding this height typically face stricter codes and standards aimed at addressing the unique challenges such as evacuation procedures, emergency response, and structural integrity under various conditions.

While other height figures may be referenced in different contexts or codes, the 45-meter classification aligns with many building codes and safety standards across various jurisdictions, making it the correct choice in this scenario.
