Modular or Manufactured Housing?
Mobile homes are now called “manufactured” homes. The Manufactured Housing Institute defines a manufactured home as "a single-family house constructed entirely in a controlled factory environment, built to the federal Manufactured Home Construction and Safety Standards, better known as the HUD Code" with a permanent chassis for transportability.
Like manufactured houses, modular homes are built in a factory and quality inspected every step of the way. Unlike manufactured homes, the pieces (“modules”) of the house are transported to the building site where they are put together by a local building contractor, and they have no chassis or wheels. Also, modulars must conform to building codes in your specific location.
