What is the minimum number of exits required for a building with an occupancy load of 500 per story?

In commercial buildings, the number of exits required is primarily determined by the occupancy load and the building’s use. For a building with an occupancy load of 500 per story, building codes typically mandate a minimum of two exits. This requirement ensures adequate egress in emergencies, providing occupants a safe means of escape in case of fire, smoke, or other hazardous situations.

Having only one exit for such a large occupancy would pose a significant risk. In life safety scenarios, it is critical to provide multiple exits to reduce congestion and allow simultaneous use during an evacuation. The presence of at least two exits enhances safety by ensuring that if one exit is blocked or inaccessible, occupants have an alternative route to evacuate the building effectively.

Thus, the requirement of two exits aligns with both safety regulations and the best practices in building design for accommodating a large number of occupants.
