Final answer:
Notches in bearing walls cannot exceed one-sixth of the depth of a wooden joist or stud and should not be located in the middle third of the span, as per typical building codes to maintain structural integrity.
Step-by-step explanation:
In regards to bearing walls, the size of a notch that can be cut into a wooden load-bearing structural member is limited by building codes. In regards to bearing walls, a notch must not exceed 25% of the width of the beam or joist.
This is to avoid weakening the structural integrity of the wall or floor system. Notches that exceed this limit can compromise the strength and stability of the structure, potentially leading to failure or collapse.
Typically, these codes will specify that a notch in a wooden joist or stud cannot exceed one-sixth of the depth of the member and should not be located in the middle third of the span. The intention is to ensure the structural integrity of the wall is not compromised. It's important to consult the specific building codes relevant to your location as they can vary.
