Tink is correct on the 36 inches. 11 inch minimum tread depth, 4-7" riser (no more than 3/8" difference between any treads either height or depth). I remember a study done recently on riser heights and stairway accidents that could eventually lead to a move toward the lower end of riser heights becoming standard.
Just call me Mike
