Do deck stairs have to land on concrete?
Stair landings must be at least as wide as the stair and at least 3 feet deep. On the other hand, solid, flat, and stable materials, such as concrete, flagstone, pavers, or brick, can be installed with a measurable slope and will not usually shift under the weight of an off-balance person completing a stairway descent.
Do deck stair stringers need support?
Stringers typically have two bearing points, with the plumb (vertical) cut bearing on a rim joist or on a beam, and the seat (horizontal) cut bearing on—at minimum—a solid landing. To help resist both vertical and lateral loads, stringers require proper support and attachment at these bearing points.
