Which dwelling is defined as an assembly of four major components: chassis, floor, wall, and roof systems, though built with various materials, and is basically frame construction?

• A. Masonry
• B. Hollow-core door
• C. Joists
• D. Manufactured Home

Answer: (D)

This item tests recognizing a dwelling defined by a frame-based assembly consisting of a chassis, floor, wall, and roof—built with various materials. A manufactured home fits this description because it is constructed as a complete framed structure in a factory, typically on a steel chassis, with the four major subsystems—the chassis for the base and mobility, and the floor, walls, and roof forming the building’s frame. The materials can vary, but the defining feature is this four-part frame construction that holds the whole dwelling together.

In contrast, masonry refers to buildings whose strength comes from brick or concrete walls rather than a separate chassis-and-frame system; a hollow-core door is just a door component, not a dwelling type; and joists are just framing members, not a complete dwelling.
