In a single family dwelling, when framing openings in floors, when are hangers required for header-joist to trimmer joist connections?

When the header joist span exceeds 4 feet
When the header joist span exceeds 5 feet
When the header joist span exceeds 6 feet
When the header joist span exceeds 7 feet

The correct answer is: When the header joist span exceeds 6 feet

Hangers are required for header-joist to trimmer joist connections in a single-family dwelling when the header joist span exceeds 6 feet. This requirement is based on structural integrity and safety considerations. When the span of the header joist exceeds this limit, additional support is necessary to ensure that the load is adequately transferred to the trimmer joists, preventing potential sagging or failure. By using hangers in these scenarios, you provide the necessary strength and support to maintain the overall stability of the floor framing system, particularly when it comes to creating openings for things like stairwells or large penetrations in the floor structure. Understanding this requirement helps ensure compliance with building codes and industry best practices, which are critical for the safety and reliability of construction projects.
