What is the depth limitation for notches in the top or bottom of rafters or ceiling joists?

1/4 of the depth
1/3 of the depth
1/6 of the depth
1/2 of the depth

The correct answer is: 1/3 of the depth

The correct limitation for notches in the top or bottom of rafters or ceiling joists is set at one-third of the depth of the member. This guideline is established in building codes to maintain the structural integrity of the rafters and joists, preventing undue stress and potential failure. When notching exceeds this limitation, it compromises the strength of the structural member. The one-third limit helps ensure that enough material remains to bear loads safely and maintain overall stability. Notching beyond this depth could create vulnerabilities that lead to sagging or collapse under applied loads.
