Start here to plan for the construction of deck or porch stairs. This article defines basic stair terms: rise, run, stringer, tread and othe rcomponents. We describe options for different types of stair supporting stringers and we give advice about choosing lumber to build deck stair stringers...

Typically we use our stringer 2x lumber (before it has been cut to length) for this purpose since by definition the diagonal stringer will be longer than the horizontal stair run. This approach works to measure and design a stairway over any irregular surface. ...
see STAIR STRINGER DEFECTS The notched stringer approach shown at left is very secure provided that the stringer depth is great enough and the cutout depth shallow enough that the remaining stringer material is strong enough to carry the weight of the stairway and its users (1-? arrow in ...
If I attach the pre-made stringer from the deck to the slab, ensuring that the top of the deck to the next stair down is the same height as the rest, then the riser height from the slab to the first stair is greater than a 3/8' variation from the rest of the riser heights by ...
(4) Stairs that follow the contour of tanks or other cylindrical or spherical structures where the construction requires the inside clearance between the inside stair stringer and wall or tank side to be 8 inches or less, shall not be considered an "open side." ...
