What is the minimum square footage requirement per person in assembly areas?

In assembly areas, the minimum square footage requirement per person is typically based on ensuring that there is adequate space for occupants to safely occupy the area without overcrowding. The correct requirement of 20 square feet per person is designed to promote both safety and comfort. This amount of space allows for circulation within the assembly area, emergency egress in the event of an evacuation, and adequate room for seating and movement.

If the space provided is less than 20 square feet per person, it may lead to congestion during events, making it difficult for individuals to move freely and potentially compromising their safety during emergencies. The National Fire Protection Association (NFPA) and local codes often establish these standards to ensure that assembly areas can accommodate people not just in terms of seating but also in terms of overall safety.
