What is the minimum stair width if the occupancy exceeds 50 people?

When determining the minimum stair width required for an occupancy exceeding 50 people, building codes often specify that a minimum width of 44 inches is necessary. This standard is in place to ensure safe egress during an emergency, allowing enough space for occupants to exit quickly and efficiently.

The rationale behind this requirement is based on the potential for a high number of people needing to evacuate simultaneously. Insufficient width could lead to overcrowding and hinder safe movement, increasing the risk of panic and injury. The 44-inch width criterion is intended to accommodate large volumes of occupants and facilitate smooth, swift evacuation.

In buildings designed for high occupancy, wider stairs can significantly enhance safety and accessibility. Hence, following the 44-inch minimum guideline is essential for buildings that expect a significant number of individuals to occupy them.
