Which home type is assembled at the factory in two or more all-inclusive sections with utilities installed at the factory?

• A. Modular Home
• B. Panelized Home
• C. Precast concrete
• D. Protected stairs

Answer: (A)

The idea being tested is off-site, factory-built construction where large, finished sections are produced, include utilities, and then are assembled on the job site. That describes modular construction, where the home is divided into two or more modules that are manufactured in a factory as complete, self-contained units with plumbing and electrical already in place. After transportation, these modules are joined together on site to form the full house.

This differs from other methods. Panelized construction uses large wall panels that are assembled on site; utilities are typically routed during or after assembly rather than being pre-installed inside fully finished modules. Precast concrete refers to concrete components cast in a factory, but it isn’t inherently described as a two-or-more-module residential system with utilities installed in the factory. Protected stairs aren’t a home type of construction at all.
