Manufactured and mobile home inspections

Manufactured homes are built to a federal code rather than local building codes. Inspectors check many of the same systems, with a few important differences.

HUD label and data plate

Each transportable section of a HUD-code home has a red metal certification label on the exterior. Inside, usually in a kitchen cabinet or bedroom closet, is a data plate listing the manufacturer, serial number and design zones. Missing labels can complicate financing and insurance.

Foundation and support

  • Piers and pads should be level and in contact with the frame.
  • Tie-downs or an engineered seismic system should be present and tensioned.
  • Skirting should be intact with ventilation and access.
  • The crawlspace should be dry, without standing water.

California requires certain earthquake-resistant bracing systems to be installed by licensed installers and to carry certification.

Common findings

  1. Roof leaks at seams, especially on older metal roofs.
  2. Soft floors near bathrooms and the water heater.
  3. Polybutylene plumbing in older units.
  4. Aluminum wiring in some 1960s and 1970s homes.
  5. Additions or carports attached without approval.
  6. Water heater closets with exterior access that need proper venting and strapping.

Park versus private land

In a park, the space rent, park rules and the park’s responsibility for utilities matter as much as the home. On private land, ask whether the home is permanently attached and taxed as real property.

Common questions

Can I get a mortgage on a manufactured home?

Yes, in many cases, especially when the home is on a permanent foundation and land you own. FHA and other lenders have specific requirements, sometimes including an engineer's foundation certification.

What is the difference between "mobile" and "manufactured"?

Homes built before June 15, 1976 are usually called mobile homes. Homes built after that date under the HUD code are manufactured homes.
