Handicap Railing Height: Understanding the Regulations

The Americans with Disabilities Act (ADA) sets out specific guidelines for handicap railing height to ensure that individuals with mobility impairments have safe and accessible routes. In this article, we'll explore the regulations surrounding handicap railings, including when they can be discontinuous and how vertical clearance is affected by handrail perimeter dimensions.

According to Section 1029.16.1 of the ADA Standards for Accessible Design, handrails serving stepped or ramped aisles are permitted to be discontinuous. However, there are four exceptions to this rule:

* For every half-inch (12.7 mm) increase in handrail perimeter dimension above 4 inches (102 mm), the vertical clearance dimension can be reduced by one-eighth inch (3.2 mm).

* Handrails along walking surfaces with slopes of 1:20 or less are allowed to have obstructed gripping surfaces, as long as they are integral to crash rails or bumper guards.

* Within dwelling units, handrails may be interrupted by newel posts at turns or landings.

* In dwelling units, the use of volutes, turnouts, starting easing, and starting newels is permitted over the lowest tread.

Additionally, handrail brackets or balusters attached to the bottom surface of the handrail that do not project horizontally beyond the sides of the handrail within 1.5 inches (38 mm) of the bottom of the handrail are considered non-obstructive.

In conclusion, handicap railing height is a critical aspect of ensuring accessibility for individuals with mobility impairments. By understanding the regulations surrounding discontinuous handrails and vertical clearance, architects, builders, and property owners can create safe and accessible routes that meet the needs of all users.
