Which occupancy category does a nightclub fall into?

A nightclub is categorized as an assembly occupancy because it is a space designed for people to gather for social activities such as dancing, dining, or entertainment. Assembly occupancies typically include places where groups of people come together for events or performances, and they often have specific safety regulations to address the unique risks associated with large crowds, such as egress requirements, fire safety measures, and occupancy limits.

In contrast, residential occupancy refers to spaces where people live, like homes or apartments; institutional occupancy includes facilities like hospitals or schools where people receive care or education; and commercial occupancy typically describes spaces used for business purposes, such as offices or retail shops. Therefore, the nightclub fits best in the assembly category due to its primary function of hosting gatherings and entertainment events.
