mobile home

trailer home, caravan

These homes are built in factories, rather than on site, and then taken to the place where they will be occupied. They are usually transported by tractor-trailers over public highways. They are less expensive per square foot than site-built homes, and are often associated with rural areas and high-density developments, sometimes referred to as trailer parks. In the UK and USA they are at times referred to as "communities".

1. a large house trailer that that can be connected to utilities and can be parked in one place and used as permanent housing
(synonym) manufactured home

A housing unit built on a movable chassis and moved to the site. It may be placed on a permanent or temporary foundation and may contain one room or more. If rooms are added to the structure, it is considered a single-family housing unit. A manufactured house assembled on site is a single-family housing unit, not a mobile home. (DOE5)
