What type of housing is largely assembled in factories and then transported to sites of use?

The correct answer is manufactured housing. Manufactured housing refers to homes that are constructed in factories according to stringent federal regulations and building codes, primarily under the HUD Code. Once the manufacturing process is complete, these homes are transported to their designated locations, where they are set up on foundations or designated sites.

This method of construction allows for better quality control, as homes are built in a controlled environment, and it often results in lower costs compared to traditional construction methods. Manufactured homes can be permanent or temporary structures, but they are typically designed to be moved, which distinguishes them from traditional homes that are built directly on-site and are generally not intended to be relocated.

Modular homes, while also prefabricated, are assembled in sections and adhere to local building codes as if they were traditional homes when they arrive at the site. However, these homes are usually constructed to be more permanent and are often not referred to as manufactured housing. Traditional and site-built homes, on the other hand, are constructed entirely on-site, rendering them distinct from the factory-based assembly of manufactured housing.
