In conventional light-frame construction, what is a common limitation for the distance between bored holes within a stud?

In conventional light-frame construction, the spacing of bored holes within a stud is governed by structural integrity and fire safety considerations. The requirement that holes must be at least 1 inch apart helps to ensure that the remaining material of the stud maintains sufficient strength and does not compromise the stud's load-bearing capacity. If holes are too close together, it can weaken the stud, potentially leading to structural failures under load.

This guideline also helps prevent issues related to the integrity of electrical and plumbing installations that may pass through the studs. Maintaining this minimum distance provides adequate support for the surrounding materials, ensuring that the overall structure remains safe and functional.

The alternative options suggest greater or lesser spacing requirements, which could either weaken the stud or complicate the installation of electrical and plumbing systems, but the 1-inch rule strikes a balance, making it an essential practice in construction standards.
