What is the minimum required width for stairways when the total occupant load is less than 50?

1. 30 inches

2. 36 inches

3. 40 inches

4. 44 inches

The correct answer is: 36 inches

The minimum required width for stairways when the total occupant load is less than 50 is set at 36 inches. This dimension is based on safety codes and regulations that aim to ensure adequate accessibility and egress for occupants in a building. Staircases must be designed to accommodate individuals safely in both everyday use and emergency scenarios, where quick evacuation might be necessary. While 30 inches is a reasonable width for certain applications, it might not provide sufficient space for two individuals to pass each other comfortably, particularly in urgent situations. Wider options like 40 inches and 44 inches provide more space, but they are not mandated for this specific occupancy level, making them unnecessary in this context. The 36-inch width serves as a balance between operational needs and safety regulations for buildings with a smaller occupant load.
