Since 1976, every manufactured home sold in the United States has been built to HUD code — a federal performance-based standard covering structural design, fire safety, plumbing, electrical, energy efficiency, and wind/seismic performance. Unlike site-built homes (which follow whatever local code their city adopts), HUD code is uniform nationwide and is enforced through factory inspections at every stage of construction.
The home leaves the factory 90–95% complete. It's transported in one or more sections to your land, set on a foundation, connected to utilities, and finished by licensed installers. The result is a permanent, real-property home — not a trailer, not a mobile home, and not temporary housing.
Today's models look and feel nothing like the manufactured homes from a generation ago. Drywall interiors, 9-foot ceilings, kitchen islands, walk-in closets, dual-zone HVAC, and smart-home wiring are now standard or affordable upgrades.
