Stairs can be one of the more challenging aspects of a deck-building project.
When building stairs, you not only need to be a good craftsperson, but, in many cases, you also need to have a solid background in both math and geometry. However, as you will learn, not all stair-building projects need to be complicated. Although the straight-stair type is among the most popular and easiest to construct, it is just one of many layouts. No sense in skimping when it comes to stair width. For safety's sake, building code requires that tread and riser dimensions are consistent for the length of the stairs.
