In the United States, there are several regulations regarding handrail installation. When installing a handrail at home or in a commercial building, you must comply with certain safety regulations to ensure the safety and accessibility of individuals using stairs, ramps, and other elevated platforms.
Specific regulations will vary depending on your location. There are state-specific and national laws, so you’ll need to do your research to ensure compliance.
However, this article will detail some general guidelines for installing a code-compliant handrail system at home or in the workplace.
Height and Clearance
The height of handrails should be between 34 and 38 inches above the nosing of the stair treads or the ramp surface. The gap between the wall and the handrail should be 1.5 inches. These specifications ensure that the handrails are easy to grab.
Gripability
Handrails should be easy to grip, meaning they need to be made out of a suitable material that is the right shape and diameter. In most jurisdictions, handrails must be between 1.25 inches and 2.63 inches. It must be smooth and free from sharp edges that could cause injuries.
Gripability is particularly important in slippery areas, such as in bathrooms and outdoor ramps. Therefore, when installing a handrail as part of bathroom renovations for older adults and people with disabilities, handrail material and surface material are vital considerations.
Structural Strength
Handrails must be structurally safe and able to withstand a certain amount of pressure. They must be securely anchored to the supporting structure (usually a wall).
In many areas, handrails are required to withstand up to 200 pounds of force, applied in any direction and at any point along the length of the handrail. However, the exact requirements might differ across states.
Compliance with ADA Regulations
The US Department of Justice enacted the Americans with Disabilities Act (ADA), protecting people with disabilities from discrimination. Handrails must be installed in accordance with ADA standards for accessible design to ensure disabled individuals can use them appropriately.
According to ADA standards, handrails must:
- Have a gripping surface with a circular cross-section and a diameter of between 1.25 and 2 inches
- Have horizontal projections at least 1.5 inches below the handrail, located at the top and bottom of the stairs or ramp
- Run continuously up a flight of stairs or along a ramp
- Be between 34 and 38 inches above the ground
- Have a vertical clearance of 9 inches between the upper and lower handrails
Handrails Markings and Contrast
Handrails must have clear markings with contrasting colors to the surrounding environment to comply with US handrail laws. For example, a handrail on a white wall must be made from dark wood, painted in a dark color, or decorated with dark-colored markings. With contrasting colors and markings, the handrails are easier to spot for those with visual impairments.
The finish of the handrail should be smooth, without any reflective or glossy surfaces that could cause glare or confusion for individuals with visual impairments. A matte or non-slip finish is usually the best choice for ADA compliance and accessibility for people with disabilities.
