Editorial advisor Mifye Guertin replies: I can think of three approaches, and none is perfect. Each is a trade-off between following the code, appearance, and complexity of layout and labor. The simplest and most code-compliant solution is to build a one-step-high, 8-ft.-long landing on top of the concrete slab that will extend at least 3 ft. beyond the bottom riser of the stairs to the deck. Frame the landing level, with one side taller than the other to account for the out-of-level slab. Then you can cut a conventional set of stairs between the landing and the deck with even riser heights. I'd make the landing 6 in. high at one end and 71/2 in. at the other. That leaves 293/4 in. total rise from the landing to the top of the deck, which translates into three treads and four risers at 77/16 in.
