What is the main characteristic of a factory-built housing?

The main characteristic of factory-built housing is that it is constructed in a factory for occupancy. This process involves the manufacturing of housing units in a controlled environment where quality can be maintained and efficiencies realized. These homes are typically built in sections or modules and then transported to the site for assembly. This method can significantly reduce construction time and costs compared to traditional on-site building practices.

Factory-built housing encompasses a variety of forms, including modular homes, panelized homes, and manufactured homes, which highlights its versatility and appeal in the housing market. The focus on factory construction allows for standardized processes, improved labor conditions, and often a more predictable building timeline.

The other choices emphasize characteristics that are not specific to factory-built housing. For example, building on-site only contradicts the central aspect of factory construction. Additionally, stating that these homes are exclusively for commercial purposes is incorrect, as they are widely used for residential living. Finally, characterizing them as a type of mobile home that cannot be moved overlooks the fact that many factory-built houses are designed to be either permanent or relocatable, depending on the type of housing model used.
