Which of the following is not a type of factory-built home?

Single-family dwellings are typically constructed on-site rather than being factory-built. A single-family dwelling refers specifically to a standalone residential building designed for one family, and the process usually involves traditional construction techniques rather than the prefabrication methods used for modular, manufactured, or prefabricated homes.

In contrast, modular homes are constructed in sections or modules in a factory and then assembled on-site. Manufactured homes are also factory-built but are constructed to specific federal standards and transported to the site as complete units. Prefabricated homes encompass a broader category of homes that are partially or completely built in a factory setting before being assembled or installed on their final site. Each of these terms specifically applies to homes that are at least partially built in a controlled environment before being moved to the final location, distinguishing them from traditional single-family dwellings.
