In determining the appropriate use group classification for a restaurant that seats no more than 40 people, it is essential to understand the specific classifications outlined in building codes.

A restaurant is typically classified under Assembly use groups due to the presence of patrons gathering for dining. However, the key detail is the seating capacity. Since the restaurant seats 40 people or fewer, it falls under Business Group B classification rather than the Assembly groups.

Business Group B is designed for facilities that accommodate fewer than 50 people where services are provided. This includes small restaurants and coffee shops, distinguishing them from larger Assembly Group A classifications, which generally apply to facilities with higher occupancy, such as theaters or sports facilities.

In contrast, Assembly Group A classifications involve higher occupancy numbers and are divided into subcategories based on the nature of the assembly—A-1 for theaters, A-2 for dining establishments with larger seating capacity (typically over 49), and so on. Mercantile Group M pertains to retail and sales areas, which do not fit the operational focus of a restaurant.

Therefore, the correct classification is Business Group B, aligning with the parameters for a small restaurant setting.
