A mobile home is a prefabricated dwelling built to be transported to a site and occupied as a residence. Common informal synonyms include trailers and, in some regions, caravans. Although they can be moved, most mobile homes remain on a permanent or semi-permanent lot, where they are connected to utilities and fitted with skirting or anchored to a foundation system.

Characteristics and common types

Mobile homes vary in size, layout and construction. Basic factory-built methods speed production and lower costs compared with on-site building. Typical distinctions include size and how sections are delivered:

  • Single-wide: a single long section that is transported intact and assembled on site.
  • Double-wide (and multi-section): two or more sections transported separately and joined to create larger floor plans.
  • Park model: smaller units intended for recreational or seasonal use in managed communities.

Externally, mobile homes usually sit on steel chassis for transport; after siting they may be placed on piers, a perimeter foundation, or other supports and fitted with exterior skirting. Interior features range from modest finishes to layouts similar to conventional houses.

History, regulation and terminology

The concept of towable living units dates to early 20th-century travel trailers and became more residential after World War II. In the United States the term "manufactured home" was introduced by federal regulation in 1976 to describe factory-built homes that meet the federal Manufactured Home Construction and Safety Standards (often called the HUD Code). That regulatory distinction separates manufactured homes from modular homes (built in sections to local building codes) and from recreational vehicles, which are designed primarily for temporary use.

Regulation, safety requirements and terminology vary by country and jurisdiction. Local zoning laws determine where mobile homes may be sited, whether in dedicated parks, on private land, or in mixed residential areas. Anchoring, wind-resistance standards and utility hookups are typical aspects governed by regulation.

Uses, benefits and practical considerations

Mobile homes serve a variety of housing needs: affordable long-term housing, seasonal or vacation dwellings, temporary emergency shelter, and flexible housing for changing needs. Key advantages often cited are lower initial cost, faster delivery than site-built houses, and the ability to place housing on unused parcels.

  • Financing: they may be financed as personal property (chattel) or real property depending on whether the home is permanently affixed to land; this affects loan terms and resale.
  • Maintenance and insurance: specific policies and maintenance needs differ from conventional homes—roof, chassis and tie-downs require attention.
  • Zoning and park rules: placement can be limited by local ordinances or by park management covenants.
  • Depreciation and resale: manufactured units historically depreciate differently than site-built homes, influencing investment considerations.

Despite occasional stigma, modern factory techniques and improved standards have increased durability and design options. Prospective buyers should compare construction standards, local regulations, lot ownership, and financing implications to ensure a mobile home meets long-term needs.
