What is the minimum size for an exit discharge in a building?

The minimum size for an exit discharge—specifically the area where occupants can safely exit the building and reach a public way—needs to allow for safe and efficient evacuation. An exit discharge must provide ample space for individuals to gather and move away from the building without feeling congested or threatened, especially in emergency situations.

A size of 10 feet by 10 feet is sufficient to ensure that a reasonable number of people can exit the building and have an area to quickly disperse once outside. This dimension strikes a balance between providing enough space for safe exit and being manageable within the overall design and safety regulations of the building.

Larger dimensions, such as 15 feet by 15 feet or 20 feet by 20 feet, may be required in certain facilities or under specific circumstances, but as a minimum standard, the 10-foot by 10-foot size is the accepted baseline for most typical scenarios.
