Side-by-Side Comparison
| Category | Mobile Home | Modular Home |
|---|---|---|
| Construction Standard | Built to federal HUD code (post-1976) | Built to local/state building codes (IRC/IBC) |
| How It Arrives | Transported on its own steel chassis with wheels and axles | Transported in sections on flatbed trucks, then assembled on-site |
| Transport Permits | Oversize load permits required in every state the route crosses | Standard oversize load permits for each section being transported |
| Typical Cost Range | $3,000 - $15,000 depending on size and distance | $10,000 - $50,000+ due to crane work and on-site assembly required |
| Timeline | 1-7 days for transport, 1-2 weeks for full setup | 1-3 days transport per section, 4-8 weeks for full assembly |
| Can It Be Moved Again? | Yes — designed to be relocatable on its permanent chassis, though older homes may not meet current codes | Rarely — once assembled on a permanent foundation, moving requires disassembly which is costly and complex |
| Foundation Type | Piers, blocks, or runners (non-permanent foundations common) | Permanent foundation required (concrete slab or basement) |
| Regulatory Body | Federal HUD (U.S. Dept. of Housing & Urban Development) | State and local building departments |
Key Differences That Affect Your Move
Foundation Requirements
Mobile homes can sit on non-permanent foundations (piers, blocks, runners), making them easier and cheaper to set up. Modular homes require a permanent concrete foundation — slab or basement — adding significant cost and preparation time.
Financing & Insurance
Mobile homes on non-permanent foundations are often financed as personal property (chattel loans) with higher interest rates. Modular homes on permanent foundations qualify for conventional mortgages with better terms and are typically easier to insure.
Value Over Time
Mobile homes generally depreciate like vehicles, especially on leased land. Modular homes, treated as real property on permanent foundations, tend to appreciate in value similar to traditional site-built homes.
Zoning & Placement
Mobile homes face zoning restrictions in many areas — some neighborhoods, HOAs, and municipalities restrict or prohibit them. Modular homes, built to local codes, are generally accepted wherever site-built homes are allowed.
Which Type Do You Have?
Not sure whether your home is a mobile home or a modular home? Here are the quickest ways to tell:
You Have a Mobile Home If...
- It was built after June 15, 1976 and has a HUD certification label
- It sits on a steel chassis with axles (even if wheels are removed)
- It was transported as a complete unit to its current location
- Your title says "manufactured home" or "mobile home"
You Have a Modular Home If...
- It was built in a factory but assembled on a permanent foundation
- It has no steel chassis underneath — it sits directly on the foundation
- It was transported in sections and assembled on-site by contractors
- It was inspected and permitted by local building authorities, not HUD
