When boring a hole in a solid wood floor joist, the hole should be at least how many inches from the top or bottom edge?

The correct choice of at least 2 inches emphasizes the importance of maintaining the structural integrity of the solid wood floor joist when performing modifications such as boring holes. When a hole is drilled too close to the edge of a joist, it compromises the joist’s ability to carry loads effectively. Specifically, drilling within 2 inches from the top or bottom edge helps to ensure that enough material remains around the hole to maintain the strength and load-bearing capacity needed to support the structures above. This guideline is often adhered to in building practices as it helps minimize the risk of weakening the joist and potential failure of the structure.

In the context of building codes and best practices, staying within this distance also helps prevent issues related to cracking, splitting, or other types of damage that might arise from improper placement of holes in joists. Understanding and following these recommendations is critical for home inspectors, builders, and anyone involved in structural work to ensure safety and compliance with applicable regulations.
