The leading (front) edge of a staircase step tread/run is referred to as the nosing. Stair landings should meet these same requirements, but again, this is not stated specifically in the 2010 ADA Standards. Stair treads must meet requirements for floor or ground surfaces which specify that the treads and landings need to be mostly flat, surface openings cannot allow passage of a sphere more than ½ inch in diameter, and the surface must be stable, firm and slip resistant. EXCEPTION: Treads shall be permitted to have a slope not steeper than 1:48.” Treads are also sometimes referred to as “runs”. 2010 ADA Standard 504.4, Tread, states, “Stair treads shall comply with 302. ![]() Also, some ambulatory disabled individuals who use the steps may use the riser backing to slide their foot up to the level of the next step. This part of the step, sometimes referred to as a riser backing, cannot be open because it could allow a crutch tip or the foot of an ambulatory disabled individual to slip through the opening which could cause a fall. The graphic below is representative of this Standard.Ģ010 ADA Standard 504.3, Open Risers, states, “Open risers are not permitted.” Riser is a reference to the vertical part of the staircase step. Treads shall be 11 inches (280 mm) deep minimum.” A common measurement is for the riser heights to be within 3/8 inch of each other in height. Risers shall be 4 inches (100 mm) high minimum and 7 inches (180 mm) high maximum. 2010 ADA Standard 504.2, Treads and Risers, states, “All steps on a flight of stairs shall have uniform riser heights and uniform tread depths. State and local building codes may have useful information about staircase landings. Some isolated areas of the Standards mention landings in staircases but specifics regarding length, width, slope, surface conditions are not included. The 2010 ADA Standards do not specifically break out staircase landings. Technical requirements for stairs are covered in 2010 ADA Standard 504. Stairs that connect play components shall not be required to comply with 504.Īlthough these requirements do not mandate handrails on stairs that are not part of a means of egress, State or local building codes may require handrails or guards.In assembly areas, aisle stairs shall not be required to comply with 504.4.In alterations, stairs between levels that are connected by an accessible route shall not be required to comply with 504, except that handrails complying with 505 shall be provided when the stairs are altered.In detention and correctional facilities, stairs that are not located in public use areas shall not be required to comply with 504.2.It is my pleasure to serve your needs.There are four exceptions to this Standard. ![]() If you can't find what you are looking for contact me, we can make almost every kind of iron design.
