• Ensure the stringer step is at least the depth of two full boards
plus a 1/8” to 3/16” gap between boards.
• For gapping requirements, see page 3
• Ensure there is at least one stringer for support in the middle of
the stair span.
• Stair landings and multi-level decks where there is a step down
should use the same structural support as required on stairs.
