What is required for the header when framing a stairwell opening that is 5 feet wide by 5 feet long

• A. Use approved hanger with double header
• B. Install a single header
• C. Dovetail the header
• D. Install a double header

Answer: (D)

When framing a stairwell opening, the header must carry the load from above down to the supports. A five-foot span is wide enough that a single header usually isn’t strong enough to resist bending and keep deflection under control in a bearing wall. Installing two header members (a double header) increases bending strength and stiffness, distributing the weight more effectively and reducing the risk of sag or failure. This setup is typically paired with king studs and jack studs on each side to transfer the load properly to the wall below, and a spacer helps keep the assembly aligned with the surrounding framing. Other approaches, like using a header with joist hangers or dovetailing, don’t provide the same reliable load transfer across that opening, so the double header is the appropriate choice here.
