Which of the following is NOT a common type of commercial building?

The choice of a single-family home as the answer is accurate because single-family homes are primarily classified as residential properties rather than commercial buildings. Commercial buildings are designed for business purposes and include structures such as office buildings, retail stores, and warehouses, which serve various commercial functions.

In contrast, single-family homes are meant for private living purposes and do not fall under the category of commercial real estate, which is typically associated with generating revenue through rental income or business operations. This distinction is crucial in understanding different property types in real estate and their intended uses.
