In Type III-B construction, which is a common classification for buildings, there are specific criteria set by the building codes that dictate the allowable area for structures, including restaurants. The basic allowable area without any additional increases for height or the installation of sprinkler systems is primarily determined by the occupancy classification and the construction type.

For Type III-B constructions, the base allowable area can be found by referencing the International Building Code (IBC), which provides standard table parameters based on occupancy. Since restaurants typically fall under the business occupancy classification, the basic allowable area is generally around 9,000 square feet. However, considering that certain conditions may apply, the figure may be closer to 9,500 square feet in some interpretations depending on factors such as the number of stories and specific local amendments to the code.

The reasoning behind the correct choice reflects an understanding of these regulations, leading to the conclusion that the basic allowable area stands at 9,500 square feet for the planned restaurant under the stipulated construction type without any additional increases or modifications.
