What is the maximum percentage of a stud that can be cut when notching in bearing walls?

The maximum percentage of a stud that can be cut when notching in bearing walls is crucial for maintaining the structural integrity of the framing. When it comes to notching, the code typically allows up to 25% of the stud to be removed to ensure it can still adequately support the structure above. This percentage is established to prevent compromising the strength of the wall.

In addition to notching, boring holes for wiring or plumbing can also be done, with regulations allowing for up to 40% of the stud to be removed. This distinction reflects the difference in how both alterations affect the load-bearing capacity of the stud.

The option indicating that 40% can be removed when boring and 25% when notching accurately captures the allowable limits for modifying studs in bearing walls, ensuring that safety and structural effectiveness are prioritized. Knowing these limits is essential for anyone involved in construction and building design.
