What is the minimum space required between a handrail and an adjacent wall?

The minimum space required between a handrail and an adjacent wall is 1 1/2 inches. This measurement is established to ensure a safe and comfortable grip on the handrail while also providing enough clearance for users' hands. Insufficient space may restrict the ability to grasp the rail effectively or could create hazards if someone's hand gets pinched or caught against the wall.

The requirement of 1 1/2 inches specifically addresses safety standards, which are crucial in building design to prevent accidents, especially in stairs and ramps where handrails are essential for support. Adhering to this standard is important for compliance with building codes and regulations, ensuring that structures are safe for all users.
