In an EXTERIOR bearing wall, what is the MAXIMUM depth a stud may be NOTCHED, expressed as a fraction of its depth?
a.10 percent
b.25 percent
c.40 percent
d.60 percent
Explanation
In an exterior or bearing wall, a stud may be notched to a maximum of 25 percent of its depth. Forty percent is the notch limit for non-bearing partitions, 60 percent is a bored-hole limit for non-bearing studs, and 10 percent is more restrictive than the code requires.
