The classification of "use group" in building regulations is primarily determined by occupancy type. This categorization is critical because it governs how buildings are utilized and the level of risk associated with that occupancy. Each use group signifies a specific category of activities, like residential, commercial, educational, or industrial, and the codes provide standards to ensure the safety, health, and welfare of the public based on how those operations will function within the building.

Occupancy type takes into consideration factors such as the number of occupants, the activities being performed, and the potential hazards associated with those activities. For instance, a building classified as a hospital (which falls under a certain use group) will have different safety requirements compared to a warehouse. These requirements influence various aspects, including fire safety, egress, and structural provisions.

In contrast, architectural style, construction materials, and geographic location, while important in their own right in terms of design and regulatory compliance, do not directly define the use group classification. The use group is specifically based on the function and nature of the occupancy within the building, which dictates the applicable safety codes and standards relevant to that use.
