What is the maximum projection of a handrail into a stairwell in inches?

The maximum projection of a handrail into a stairwell is defined to ensure safety and accessibility for users navigating the stairs. A projection of 4 1/2 inches is typically the accepted standard because it provides adequate space for users to pass without an increased risk of hitting their hands or bodies on the handrail. This distance accommodates various building codes and guidelines, which emphasize both safety and functionality in stair design.

In many jurisdictions, regulations dictate that handrails should not extend too far into the stairway's horizontal plane to avoid obstructing movement. By allowing a projection of 4 1/2 inches, it strikes a balance between providing adequate support and ensuring that the pathway remains unobstructed. Understanding these measurements is important for property inspectors as they evaluate stairwells for compliance with safety codes.
