How much of a load bearing stud's depth may be notched?

The correct choice indicates that a load-bearing stud may have up to 25% of its depth notched. This guideline is essential to maintain the structural integrity and load-bearing capacity of the stud. Notching a stud can weaken its ability to carry loads, which is why there are strict limits on how much material can be removed from its depth.

Allowing a notched depth of 25% provides a balance between accommodating necessary modifications for plumbing or electrical installations while still preserving the structural function of the stud. Exceeding this limit could compromise the stud's strength, resulting in potential safety hazards. Knowing the specifics of these codes helps ensure that construction practices remain safe and effective, adhering to the standards set for residential buildings.
