These HUD-code homes are built on a permanent chassis, or frame, and pulled to the site on their own wheels. When the home is attached to a foundation, its wheels, axles, and tow hitch are removed but the fram remains a permanent fixture of the home. Manufactured homes are complete factory-built, and arrive on site complete with appliances, carpet, paint, lights, and with the utilities ready to be hooked up on site. In addition to being attached to a permanent foundation, those that are two or more sections require extra onsite completion to attach and seal the units. Manufactured Home Market
