The top of the 2nd story sub-flooring is 121.125" from the top of the sill. We then need to add 1.5" from the basement slab to the sill plus another 1/4" for the flooring, making the total rise from the slab to the top of the flooring 122.875"
The actual stairway rise will depend on the height of the stair landing:
If made with 2x6s plus 3/4" planks it will be 6.25", making the needed rise 116.625" If made with 2x8s plus 3/4" planks it will be 8", making the needed rise 114.875
15 steps of 7-3/4" (the maximum allowed by code) is 116.25"
15 steps of 7-5/8" provides 114.375"
Steps are 42.125" wide, 11.25" deep
