In this guide 3 sections
The words sound alike, but they mean different things to lenders, insurers, and communities.
| Term | Built to | Foundation | What to know |
|---|---|---|---|
| Mobile home | Before the federal HUD code (before June 15, 1976) | Varies | The older term for factory-built homes made before federal standards. Some communities and lenders won’t accept them. |
| Manufactured home | The federal HUD code (June 15, 1976 and later) | Installed and anchored to federal and state standards | Built in a factory, moved in one or more sections, and set on a site with utility hookups. |
| Modular home | State and local building codes, the same codes as site-built homes | Permanent foundation | Built in sections in a factory and assembled on site. Usually financed and appraised like a site-built house. |
The federal construction standard for manufactured homes is 24 CFR Part 3280, administered by HUD’s Office of Manufactured Housing Programs (both checked September 2026).
How to tell what you’re looking at
- The HUD label. A red metal tag on the outside of each section of a manufactured home, usually near the tail end. It shows the home was built to the HUD code.
- The data plate. A paper label inside the home, often in a kitchen cabinet, a bedroom closet, or near the electrical panel. It lists the manufacturer, serial number, date built, and the wind and roof load zones the home was designed for.
If both are missing, ask the seller for the home’s title and any records. Some lenders and insurers won’t work with a home that has neither.
Why it matters
- Approvals. Communities often have rules about the age and type of homes they accept. Confirm before you buy.
- Financing. Manufactured and modular homes are often financed differently. Our financing guide covers the options.
- Insurance. Ask insurers directly about the type and age of the home. See insuring a manufactured home.
- Resale. Installation quality, condition, and whether the home sits on land you own all affect what it’s worth.
Common questions
Is a manufactured home the same as a mobile home?
People use the words interchangeably. Technically, homes built to the federal HUD code, which started June 15, 1976, are manufactured homes. Factory-built homes from before then are usually called mobile homes.
How can I tell if a home was built to the HUD code?
Look for the red HUD certification label on the outside of each section and the data plate inside the home. Both are described below.
