I recently built a paver patio and the existing porchsteps that were removed during the process no longer fit. I am attempting to research building a new set of steps and my head is spinning with how to build these things in line with code.
I am located in Western New York. I know my rise from the ground to the house threshold is 26 inches. I don't care how long the run is as the steps are running out to a patio.
My initial thought was to buy a 3 step pre-cut stringer from Lowe's as I have never attempted to cut my own before. The stringers are 6.5 inches, which would be perfect as 6.5 * 4 is 26, with the house acting as the fourth step. Then I got to thinking that the additional inch added from the decking board would throw off this math. A 7.5 inch total height step would mean that my last step, into the house, is three inches less than the other steps (factoring in the additional thread inch for each of the three steps on the stringer).
When code references step height, is it referring to the total height between the stringer and the stair thread, or just the height that the stringer is cut to? Would it be acceptable to use the 6.5 inch stringer with the standard 1 inch decking board, for a total of 7.5 inches, meaning that the last "step" into the house would be three inches less than the steps on the stringer?
