ADA compliant stair handrails, mandatory in commercial settings, must run the full length of the Nosing Line. In residential settings, handrails conform to some but not all elements of the ADA Guidelines.
For optimal safety, whenever possible the handrail should run the entire length of the Nosing Line. The top surface of the handrail should be between 34 and 38 inches above the floor, or above the Nosing Line. Some installation guides suggest marking the height by measuring from the nosings of the steps. Determining the stair slope is required to create the correct transition angle between the horizontal and sloped sections of an ADA-compliant handrail.
If the slope is between 30 and 34 degrees, you should be able to use a standard degree bend. This code is important because it provides enough room for a person to walk and carry items up or down the stairs. Minimum railing distance means the walking space between a handrail on one wall and an adjacent wall that has no handrail. Measure this distance from the side of the handrail closest to the wall and extend the line to the wall.
When you have only one railing, you have more walking path width available than if you had two railings. Guards are the rails that protect users from falling off of high areas, such as landings. Landings can be intermediate horizontal sections within a staircase or terminal sections at the top or bottom of a staircase. Horizontal walking surfaces with a drop-off more than 30 inches down must be protected by a guard. The minimum height for this guard is 36 inches. As with exterior decking , no guards or rails are needed if the surface is close enough to the ground: 30 inches or less.
The theory is that a person may become injured by falling off of an 18 inch-high deck, for example, but nowhere near as severely as if that person fell 8 feet down. Even though building code does not require a guard for surfaces that are lower than 30 inches, it is always safest to include one in these situations.

Some staircases have open risers, which have their own building regulation requirements. Open risers should:. You can view the full Part K Building Regulations related to staircases here, including stair width, pitch, headroom and stair tread regulations. Building regulations state that stairs less than mm wide should have a handrail on at least one side.
Stairs that have a width of more than mm should have a handrail on both sides. However, if you plan to sell your house or let your property, not having the correct handrails is likely to be a problem 2.
Bear in mind as well that not having the correct handrails could make the staircase unsafe or difficult for people to use, particularly if a flight of stairs has open sides.
A stairway with fewer than four risers does not require a railing. All stairways with four or more risers and with one or more open sides require railings on the open side. A stairway in a public building must have handrails on both sides; stairways in private residences may have a railing on one side.
