What is the maximum size hole that can be placed in an interior non-load bearing stud?

In the context of building codes and standards, the maximum size of a hole that can be placed in an interior non-load bearing stud is important in ensuring the structural integrity and performance of the framing system. A 2.1-inch hole is the established limit, as it allows for necessary plumbing, electrical, or HVAC installations while minimizing the potential for compromising the stud's strength and stability.

This size is determined based on guidelines to ensure that while the stud can accommodate such penetrations, it retains enough material around the hole to support loads and resist damage during construction and occupancy. Exceeding this size could lead to weakening the stud, which can pose safety risks and structural challenges. Therefore, the code mandates this maximum size to maintain safety and reliability in residential construction.
