What is the maximum depth a wood stud can be cut or notched in bearing partitions?

In bearing partitions, the maximum depth a wood stud can be cut or notched is crucial for maintaining the structural integrity of the wall. The correct value is 25 percent of its width. This guideline ensures that sufficient material remains to support any loads applied above the stud while also allowing for necessary modifications during construction.

Cutting or notching deeper than 25 percent compromises the stud’s strength, risking failure under load conditions. This established limit is based on engineering principles that balance structural support with practical adjustments for wiring, plumbing, or other installations that may require such alterations. Therefore, adhering to this limit is essential to ensure safety and reliability in the construction of bearing walls.
