Dwelling units constructed from components prefabricated in a factory and erected on the site.
A type of housing in which major components are assembled in a factory and then shipped to the building site to be joined with other components to form the finished structure. The components are usually uniform incremental sizes, permitting some flexibility of design while maintaining the structure of individual elements. Sometimes called "prefabricated" or "prefab" housing by laymen; these terms are avoided by the industry because of negative connotations.
A relatively recent concept in home construction, aimed at producing housing more economically and faster through prefabricating processes; also called prefabricated housing. Modular methods expedite construction because the house itself can be built in the factory while the building site is being prepared, thus potentially eliminating costly delays. Some courts have held that the sale of an unattached modular home is the sale of personal property, and thus no written listing or real estate license is required to earn a commission.
