What is the requirement for holes in rafters?

The correct requirement for holes in rafters is that they must be 2 inches away from the end of the rafter notch. This guideline is established to maintain the structural integrity of the rafter while allowing for necessary modifications such as plumbing or electrical wiring.

When a hole is cut too close to the end of a rafter, it can weaken the rafter and may compromise its load-bearing capacity. By ensuring that holes are positioned at least 2 inches away from notches, the design helps to prevent potential structural failure, ensuring the safety and durability of the roof structure.

In contrast, other options either suggest distances that are too short or do not adhere to the established guidelines. Additionally, allowing holes to be made anywhere in the rafter would lead to structural deficiencies, making it critical to follow the specific spacing requirements laid out in building codes. Understanding these regulations helps inspectors ensure that construction practices uphold safety standards.
