What percentage of a wood stud's width must a hole drilled through the stud not exceed?

The correct answer is: 40%

When considering the structural integrity of a wood stud, it’s important to maintain enough material around any drilled holes to ensure that the stud can support loads without compromising its strength. The recommended practice states that a hole drilled through a wood stud should not exceed 40% of the width of the stud. This guideline helps prevent weakening the stud, which could lead to structural failure. A hole that exceeds this percentage could potentially compromise the stud's load-bearing capacity, leading to potential issues in the construction or safety of the building. The design codes reflect this limitation to promote safe building practices and ensure that structural members retain their intended performance characteristics. The answer reinforces the principle of maintaining structural integrity around drilled holes, making it a crucial aspect for anyone involved in home inspections or residential construction.
