Non-building elements such as bleachers, grandstands and folding telescopic seating, must comply with _______.

The correct answer is that non-building elements such as bleachers, grandstands, and folding telescopic seating must comply with ICC 300. This code specifically addresses the requirements for assembly seating and is crucial in ensuring safety and structural integrity for these types of installations.

ICC 300 provides provisions related to the design and construction of seating areas where a large number of people may gather, focusing on aspects such as load capacities, stability, and accessibility. Compliance with this code helps to safeguard public safety during events held in these spaces, as it sets standards that prevent potential hazards associated with crowd dynamics and structural failure.

In contrast, the other choices, ICC 100, ICC 200, and ICC 400, pertain to different aspects of building safety and are not specifically tailored to assembly seating. Therefore, understanding that ICC 300 is the appropriate code for bleachers and similar non-building seating elements is essential for professionals involved in commercial building inspection and safety compliance.
