What is the minimum width required for a hallway?

The minimum width required for a hallway is established to ensure safe and efficient movement of people, particularly in residential buildings. A width of 3 feet is specified in many building codes to accommodate the passage of individuals, including those using mobility aids such as wheelchairs or walkers. This width allows two people to pass comfortably side by side, which is important for safety during emergencies or evacuations.

Widths less than 3 feet, such as 2 feet, may create bottlenecks and hinder the flow of traffic, especially in areas where people need to move quickly or where access for emergency response is required. Wider options like 4 feet or 5 feet, while providing additional comfort and access ease, are above the minimum requirement and would not be necessary in all situations, though they can be beneficial in high-traffic areas.

Thus, a hallway width of 3 feet strikes a balance between safety, functionality, and adherence to common building regulations.
