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

The minimum space required between a handrail and a wall is typically 1.5 inches. This space is important for safety and accessibility reasons. Having adequate clearance ensures that users can easily grip the handrail and use it effectively, especially in emergencies. If the distance is too narrow, it may pose a hazard, as individuals might not be able to grasp the handrail properly or could get caught between the handrail and the wall.

Building codes and standards, such as those established by the International Building Code (IBC) and the National Fire Protection Association (NFPA), often specify this measurement to ensure uniformity and safety in various structures. The distance allows for a comfortable grip for all users, including those with mobility devices or those who may be carrying items while using the stairs.

The other options represent distances that do not adhere to these standard guidelines, which could compromise the functionality and safety of handrails in residential and commercial properties.
