Mobile vs Manufactured vs Modular Homes – What's the difference?

Looking to put a home on your land? The difference between mobile, manufactured, and modular homes matters more than most buyers realize. Getting this wrong can cost thousands. In the worst case, it can make your land purchase completely unusable for your plans.

If you're still in the land-buying stage, see Buying Land for a Mobile or Manufactured Home first. It covers what to look for in a parcel before you commit.

Mobile Homes

Mobile homes are manufactured homes built before 1976. They're often called "trailers" and do not carry a HUD insignia. Many counties will not allow mobile homes on vacant land. Only manufactured homes are typically permitted. Before buying land with the intent to place a mobile home, call the county Building Department to confirm it's permitted.

Key facts:

• Built before 1976
• No HUD code compliance
• Not allowed in many counties

In 1976, the federal government created the Mobile Home Construction and Safety Act. After that date, all manufactured homes had to pass HUD code and bear the HUD insignia. Before 1976, homes were built without that standard. That's why older units are treated differently by counties today.

Manufactured Homes

Manufactured homes are built after 1976 and must meet HUD code. They carry the HUD insignia and are delivered in one or a few large pre-assembled sections and placed on your property. Counties generally prefer these over mobile homes.

Key facts:

• Built after 1976
• Must meet HUD code
• Delivered pre-assembled in large sections
• Built in a factory at a fraction of stick-built costs
• Can be customized with hardwood floors, granite countertops, high-pitched roofs, and large porches

Important: HUD codes are updated periodically. If your manufactured home falls out of spec with a new HUD standard, it can affect its value. Foundation requirements vary by county. Some require a concrete pad, others allow limestone or a permanent foundation. Some areas require hurricane straps. Financing for manufactured homes typically requires hard money lending rather than traditional home loans. The HUD Title I program is one financing option worth researching.

Modular Homes

Modular homes are also factory-built but are not subject to HUD code. Instead, they're governed by state-level building codes. They're delivered in many separate pieces (frames, windows, doors) and assembled on-site, similar to a stick-built house.

Key facts:

• Not subject to HUD code. Subject to state building codes.
• Delivered in many pieces and assembled on-site
• More similar to traditional construction than manufactured homes
• Typically financed through a new construction loan

Cost Considerations for All Three

Both manufactured and modular options cost less than a site-built home. But if you're buying land specifically to place one of these, factor in additional costs:

• Delivery and installation
• Platform or pad construction (type specified by county)
• Septic system permit and installation
• Building permits
• Electricity hookup or solar
• Well drilling permit and installation

Call the county Building Department before purchasing land to confirm which housing type is allowed, what foundation is required, and what setback and size minimums apply. You can also check the property's zoning before you call. It will tell you what residential uses are permitted.
