Handrail gripping surfaces shall extend beyond stair flights and ramps with three exceptions. The Handrail gripping surfaces and any surfaces adjacent to them shall be free of sharp or abrasive elements, have rounded edges, and not rotate within their fittings. If the perimeter is greater than 6 1⁄4” shall have a graspable finger recess area on both sides. The gripping surface for a non-circular cross section shall have a perimeter dimension between 4 inches and 6.125 inches and a maximum cross section of 2 1/4 inches. Handrail gripping surface with a circular cross section shall have an outside diameter between 1.125 and 2 inches. Horizontal projections of the Handrail Brackets shall be 1 1/2 inches below the bottom of the gripping surface. The underside of the gripping surface should not be blocked for more than 20 percent of its overall length. This surface needs to be continuous along the length and not obstructed at its tops or sides, including the landings and corners. The Handrail gripping surface is the actual Handrail you grip while using the Handrail. Handrails have specific parameters they must meet to comply with ADA standards. The minimum vertical clearance between Handrails is 9".The maximum height from the surface is 28".Sufficient vertical clearance between upper and lower Handrails, 9 inches minimum, should be provided to help prevent entrapment. When children are the principal users in a building or facility (e.g., elementary schools), a second set of Handrails at an appropriate height can assist them and aid in preventing accidents.Ī maximum height of 28 inches measured to the top of the gripping surface from the ramp surface or stair nosing is recommended for Handrails designed for children. The height of top rails, or equivalent guardrail system members, is 42 inches, +/- 3 inches, and may not exceed 45 inches above the walking-working surface. OSHA requires the top of the gripping surfaces of Handrails shall be 30 inches minimum and 38 inches maximum vertically above walking surfaces, stair nosings, and ramp surfaces. What is the International Code Council (ICC)? 4. The IRC required the top of all Handrails must be between 34 and 38 inches measured from the walking surface or the nose of the stairs. If the guard top rail is not used as a Handrail, it would not have graspability requirements. When the 42-inch guardrail is used on a stair or ramp, a secondary Handrail will be required at the appropriate height. The IBC requires a guard to be 42 inches tall, with Handrails falling between 34 and 38 inches. The height from the surface is between 34" and 38".However, if a railing is present on walking surfaces with running slopes less than 1:20, they must comply with ADA standards. When the ramp has a slope that is less than 1:20, a Handrail is not required. If your railing run is across multiple surfaces like a ramp, stairs, and landing, it must be consistent height across all the whole railing run. Handrails must remain at a consistent height above walking surfaces, stair nosings, and ramp surfaces. The current ADA standards dictate that the top of Handrails gripping surfaces shall be 34 inches minimum and 38 inches maximum measured vertically above walking surfaces, stair nosings, and ramp surfaces with a greater than a 1:20 slope. What Is The Typical Floor To Floor Height Residential?Ģ8" with a min of 9" with above Adult Handrail.What Are The Typical Stairs Run And Rise?.Does Code Require A Handrail On Stairs?.Does A Stair Handrail Need To Be Continuous?.How Far Should The Handrail Be From The Wall?.Local building codes supersede national building codes. Customers are encouraged to call their local building jurisdiction to get information about their local building codes. Inline Design provides this information in an advisory capacity only and is not liable for any code non-compliance. Knowledge of the code requirements is important whether a Handrail is used as a standalone system or combined with an existing bar, glass, or cable railing system. While many ADA standards have been incorporated into building codes, it is essential to note that the ADA is not a building code but a standard by which a facility open to the public may be deemed accessible. In the United States, Handrail Height is based on either the ADA, IBC/ICC, OSHA, or your local building jurisdiction. Handrail Height requirements are issued to create a safe and enjoyable space for everyone.
