Which construction type is described as Wood Frame (Residential)?

• A. Type I
• B. Type II
• C. Type III
• D. Type V

Answer: (D)

Wood Frame (Residential) corresponds to Type V. In the IBC classification, Type V is the construction category that uses wood framing for the structural framework and interior members, which is why it’s the standard choice for most houses and many small apartment buildings due to cost and constructability. Other construction types rely on noncombustible materials (like concrete or steel) or mix exterior noncombustible walls with interior wood in Type III, or use heavy timber in Type IV, but Type V is specifically the wood-frame, residential option.
