Question 2
Domain 4: Wall Construction, Framing, and Exterior CoveringsWhat is the maximum height of a residential wood-frame wall per the IRC for standard construction?
Correct answer: B
Explanation
Under the IRC, standard wood-frame wall construction is limited to a maximum wall height of 10 feet for typical residential framing. This limit is used in the prescriptive provisions for wall framing and applies unless an engineered design or other approved exception is provided.
Why each option is right or wrong
A. 8 feet
B. 10 feet
IRC Section R602.3.1 limits standard wood stud wall framing to a maximum wall height of 10 feet for prescriptive construction. That 10-foot cap is the governing threshold for typical residential wood-frame walls unless the wall is specifically engineered or otherwise designed under an approved alternative method.
C. 12 feet
D. No maximum if properly engineered
