What does the term 'occupant load' indicate in building codes?

The term 'occupant load' refers specifically to the maximum permissible number of occupants in a building or a space, as defined by building codes. This measurement takes into consideration factors such as the intended use of the space, the available exits, and safety considerations to ensure that the building can safely accommodate the people within it without exceeding capacity.

Understanding occupant load is crucial for maintaining safety during emergencies, as it dictates how many people can safely evacuate the building in the event of a fire or other hazardous situation. It influences the design of exit routes, the installation of fire-safety systems, and occupancy permits.

In contrast, the design capacity for emergency exits and the ability of a structure to support weight are related concepts but do not directly define the term 'occupant load.' Similarly, the total number of floors in a building is irrelevant to the calculation of how many individuals can safely occupy a given space. Thus, the maximum permissible number of occupants is the most accurate definition within the context of building codes.
