#Irc 311 code#
The Pennsylvania Uniform Construction Code has amended section R311.5.3.1 of the International Residential Code and replaced it with exception 8 to section 1014.6 of the 1992 BOCA National Building Code and additional provisions of the 1992 CABO One and Two Family Dwelling Code namely: You are correct that the IRC does not have any maximum riser height, but your change to require a 4" minimum is not legally enforceable…particularly in your home state of Pennsylvania. We made it 4" in because a low rise height is a trip/fall hazard (people don’t see it as a step). ADAAG specifies the radius of the curvature of the leading edge of treads and the underside slope of angled or rounded nosings. Straight risers without nosings are acceptable. Angled or rounded nosings or sloped risers help prevent this hazard and provide a smoother transition. Open risers and abrupt or extended nosings (i.e., projecting more than 1 ½ inches) can catch the toe. A smooth transition from tread to tread is essential.

People without full use of a leg may drag a foot when ascending stairs. (The CABO/ANSI A117.1-1992 standard requires a riser height between 4 to 7 inches.) ADAAG requires the height to be uniform but does not specify a minimum or maximum height which is addressed by most local building codes. Variation in riser height along a set of stairs can be a tripping hazard. Uniformity is important not only between steps but along each step curved stairs, where the width of each tread varies, do not meet this requirement. Treads must be at least 11 inches wide and uniform. Nickname.Here is some more info for you out of the ADAAG.
