What are the occupancy impacts defined by the IBC?

• A. Construction cost, maintenance schedule, and procurement timelines.
• B. Load requirements, fire ratings, and egress.
• C. Electrical grounding standards and stormwater management.
• D. Material reuse policies and recycling.

Answer: (B)

Occupancy drives the design criteria in the IBC, focusing on how a space will be used and how many people it will serve. This determines the structural loads the floors must safely carry (live/occupant loads), the fire resistance required of walls and floors to contain fire and limit heat transfer, and the means of egress needed to get occupants out safely in an emergency. Those aspects—load requirements, fire ratings, and egress—are why this set best matches the IBC’s occupancy impacts. Other topics like construction cost, grounding, stormwater, or material reuse are governed by different code provisions and aren’t dictated by occupancy in the IBC.
