Is a stair nosing required by code?
Sunday, March 15, 2020
A stair nosing (extension of the tread past the front face of the riser below) is only required when a tread is less than 11 inches, according to the International Residential Code (IRC 3126.96.36.199). Since the minimum tread allowed is 10 inches, a nosing is only required for treads between 10 and 11 inches. Other criteria are that “the greatest nosing projection shall not exceed the smallest nosing projection by more than 3/8 inch,” and “beveling of nosings shall not exceed 1/2 inch."
