![]() Switchback or dogleg stairs must be continuous. Within the full length of each stair flight. Handrails are required on both sides of stairs and must be continuous Recommendation: Providing visual contrast (light-on-dark or dark-on-light) on the top and bottom steps that is approximately 2 inches wide and located either on nosings or at the leading edges of treads is helpful for people with low vision. ![]() Requirements for stairways address treads and risers, surfaces, nosings, Standards, but handrails must comply when stairs that are part of a In alterations, stairs between levels that are connected by anĪccessible route (e.g., ramp or elevator) are not required to meet the Non-public areas of detention and correctional facilities, and stairs of The Standards exempt aisle stairs in assembly areas, stairs in Means of egress nor to alternating tread devices and “ship’s ladders.” ![]() Standards do not apply to stairways that are not part of a required Required egress routes, including those comprised of a single riser. ![]() Interior and exterior stairs that are part of a required means of egress These annotations are prefaced with begin and end image notes. Some images are paired with visually hidden notes. In this document ″ indicates inches and ′ indicates feet. Notational tips for users of screen reading software follow. This guide explains requirements in the ADA Guidance on the International Symbol of AccessibilityĬhapter 10: Recreational Boating FacilitiesĬhapter 10: Swimming Pools, Wading Pools, and Spas Typically you will have one additional riser to the total number of finished treads.Chapter 3: Clear Floor or Ground Space and Turning SpaceĬhapter 6: Washing Machines and Clothes Dryers Not counting the floors or landings, count the number of finished treads. Finally, count the number of risers including the riser from the bottom floor/landing to the first tread and the riser from the last tread to the floor/landing at the top of the staircase. To obtain this measurement, place a measuring tape on the top edge of the nosing of the first tread and extend the tape along the treads nosings to the top edge of the floor/landing nose. The final measurement to acquire is the distance along the nosing. Overall length is determined by measuring the horizontal distance from the edge of the nosing on the first tread at the bottom of the staircase to the edge of the nosing on the floor/landing at the top of the staircase. The overall height is distance from the finished floor/landing at the top of the staircase to the finished floor/landing at the bottom of the staircase. Total number of treads (do not count floors and landings)įor these overall measurements, it may be easier to utilize two people. Overall length of the stairs along the tread nosingsĮ. In addition to the tread and riser details, we will need the overall dimensions of the staircase.Ĭ. Measure the distance from the top of the finished tread below to the bottom of the level (Finished Riser Height). If you find difficulty obtaining an accurate measurement because of your nosing overhang, use a level to rest upon the tread and allow it to overhang. Finally, you will need to measure the distance from the top of one finished tread to the top of the next finished tread. Next you will need to measure the total length of the finished tread from the outer edge of the nosing to the riser (Finished Tread Length). You will want to measure how far the tread extends past the riser below (Nosing Length). The first measurements involve the tread and riser details which can be easily accomplished with one person. So how do you go about filling out the Stair Measuring Guide? To start, depending upon the size of the staircase, it may be easier to take the overall measurements with the assistance of another person. Finished distance between posts measured on the horizontal, if applicable.Overall wooden post finished dimensions (i.e.Wooden post(s) location on tread from the tread nosing, if applicable.Tread material (Wood, Concrete, Stone, etc.). ![]()
