Which construction type is described as Ordinary (Strip Mall)?

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

Answer: (C)

Ordinary construction is Type III. It uses exterior walls that are noncombustible and interior framing that can be wood. Strip malls are typically built with noncombustible exterior walls (like masonry) for fire separation between units, while the interior structure is often wood to keep costs down. That combination fits ordinary construction, distinguishing it from fire-resistive Type I and noncombustible Type II, which require higher overall fire resistance; from Type IV, which uses heavy timber; and from Type V, which can be all-wood framing.
