What is the maximum allowable depth of a notch in a 2x12 floor joist not located in the middle third?

1.5 inches
3.5 inches
2 inches
4 inches

The correct answer is: 2 inches

The maximum allowable depth of a notch in a 2x12 floor joist that is not located in the middle third is indeed 2 inches. This limit is established to maintain the structural integrity of the joist, as notches can significantly weaken its load-bearing capacity. Notches in the top or bottom of a joist can concentrate stresses in those areas, particularly if the notch is too deep, leading to potential failure under load. Placing the notch in not the middle third makes it critical to adhere to conservative depth limits to ensure safety and performance. The standards are designed to prevent excessive material removal that would compromise the overall strength of the joist. Other options present depths that exceed safe limits and could result in structural concerns or failure.
