This category is for manufacturers, suppliers, distributors and constructors of residential manufactured housing. The term "manufactured home" was adopted in 1980 by the United States Congress to describe a type of house that is constructed in a factory to comply with a building code developed by the Department of Housing and Urban Development (HUD). In the past, manufactured homes were called "mobile homes," a term that many people still use. However, "mobile" is no longer an accurate name because fewer than five percent of such homes are ever moved off the owner's original site.
