In respect to this, what is the maximum height of a stair riser?
7 3/4 inches
One may also ask, can stair risers be different heights? Per the latest edition of the 2012 International Residential Code (IRC), the maximum allowed difference in riser height is 3/8". (This means that the difference in height between the tallest and the shortest riser on your stairs can be no more than 3/8".)
Similarly, you may ask, what is the maximum height of a step?
Risers must have a maximum height of seven inches and a minimum height of four inches. Single-family homes and townhouses are permitted to have a maximum riser height of 7.75 inches.
Do stairs require nosing?
You are not required to have an nosing/overhang on your stair treads. If your stairs don't have a nosing you are required to have a tread that is at least 11 inches long.
