Which of the following Group A occupancies is intended for viewing activities with spectator seating?

In the context of the International Building Code, Group A occupancies are designed for assembly purposes. Group A-4 specifically pertains to buildings or spaces intended for viewing activities that include spectator seating, such as indoor arenas, theaters, and similar venues. This classification is focused on spaces where an audience gathers to witness performances, events, or competitions.

Group A-2 covers places for food and drink consumption (like restaurants or nightclubs), while Group A-3 involves assembly areas for worship, recreation, or entertainment that do not typically include fixed seating for spectators. Group A-5 is reserved for participatory sports and activities, rather than for viewing purposes.

By distinguishing Group A-4 as the category that emphasizes spectator seating, it becomes clear why this classification is specifically designed for venues where large audiences gather to watch events, thus aligning with the intention behind the question.
