Under North Carolina Building Code, what defines a “high-rise building”?

• A. A building that is more than 50 feet in height
• B. A building that is more than 75 feet in height
• C. A building that is more than 100 feet in height
• D. A building that is three or more stories

Answer: (B)

A high-rise building in the context of the North Carolina Building Code is defined as a structure that exceeds 75 feet in height. This classification is important for several reasons, including fire safety considerations, evacuation protocols, and structural requirements. High-rise buildings often require more stringent safety measures due to their height, which impacts factors such as fire service access, egress routes, and building material standards.

Buildings that are defined simply by their number of stories, such as those that have three or more stories, do not necessarily fall into the high-rise category unless they also exceed the height threshold. Likewise, defining high rises at 50 feet or 100 feet would not align with the specific legislative framework or safety considerations that are in place in North Carolina's building code. Thus, setting the definition at 75 feet provides a clear standard that aligns with national codes and safety practices in architectural design and construction.
