What limitation applies to notches and bored holes in load-bearing walls?

Notches and bored holes in load-bearing walls are subject to specific limitations to maintain the structural integrity of the wall. The correct answer is that these modifications cannot exceed 40% of the stud depth. This limitation is essential because exceeding this percentage can compromise the load-bearing capacity of the studs.

When the depth of notches or the diameter of drilled holes is controlled, it helps to ensure that the structural elements retain enough strength to support the loads applied to them without risk of failure. Following these guidelines is critical, especially in load-bearing walls where the risk of structural collapse can have serious consequences.

Understanding these limitations helps inspectors ensure that any alterations or modifications made to a load-bearing wall comply with building codes and protect the safety of the structure.
