What are the minimum clearances required between building walls and egress paths?

The minimum clearance of 3 feet between building walls and egress paths is specified to ensure safe and accessible passage during emergencies. This clearance allows individuals to move freely without the risk of obstruction or entanglement. In situations where egress is necessary—such as during a fire or other hazardous event—having an adequate width is critical to ensure that people can evacuate quickly and safely. Additionally, a 3-foot clearance accommodates potential obstacles, such as furniture or other items that may impede movement, thereby providing a margin of safety.

Establishing a minimum distance also aligns with safety codes that seek to prevent hazards during egress. It emphasizes the importance of planning and designing exit pathways in a way that can accommodate all occupants, including those with disabilities. Thus, the requirement of 3 feet reflects a balance between safety, accessibility, and effective use of space in building design.
