What Makes a Mobile Home Inspection Different—And Why You Need One

Whether you’re downsizing, buying your first place, or looking for a budget-friendly option in a competitive market, a mobile or manufactured home can be a great fit. But because these homes are built and installed differently than traditional houses, a mobile home inspection is a crucial step in the buying process. 

Manufactured homes need to follow the federal Housing and Development (HUD) construction standards, like sitting on steel frames and using anchored or permanent foundation systems to stay level and secure.

A mobile home inspection is often required if you’re using FHA, VA, or USDA financing. Lenders might ask for both an inspection and a HUD-compliant permanent foundation certification before approving the loan, since the home’s safety and installation directly affect financing eligibility. 

For buyers, that makes understanding how the mobile home inspection process works a key component of the purchase—whether you’re buying a mobile home near Portland, OR or looking at manufactured houses in Nashville, TN.

Mobile home vs. manufactured home: What’s the difference?

• A mobile home is any factory-built home constructed before June 15, 1976, which is when HUD standards were introduced.
• A manufactured home is also a factory-built home, but constructed after June 15,1976, and meets federal HUD Code requirements for safety, installation, and construction quality.
• Many people use “mobile home” to describe both, but most of these houses on the market today are technically manufactured homes.

What does a mobile home inspection include?

A mobile home inspection often focuses on areas that differ from site-built construction. Inspectors will still look for safety concerns, signs of damage, and issues that could affect the home’s long-term stability or financing eligibility, but pay special attention to components that are specific to manufactured homes. 

Most mobile home inspections will look at:

Structural support and foundation

• Steel chassis and frame
• Piers, blocks, and footings
• Anchoring or tie-down system
• Condition of the vapor barrier and underbelly
• Whether the home appears to be installed on a permanent foundation*
  

*Permanent foundations must meet HUD guidelines, so inspectors note whether the installation looks compliant.

Roof and exterior

• Roof covering and sealants
• Siding, skirting, and under-home ventilation
• Gutters, flashing, and drainage
• Signs of moisture intrusion

Plumbing

• Pipe materials (PEX, CPVC, or older polybutylene)
• Water pressure and drainage
• Hot water heater condition
• Leaks under sinks, around fixtures, or beneath the home

Electrical

• Service panel condition
• Proper grounding
• GFCI protection
• Safe wiring materials

Heating and cooling

• Furnace operation and age
• Air conditioning function
• Ductwork and airflow

Interior systems

• Soft or uneven floors
• Window and door operation
• Ceiling stains, wall cracks, or signs of leaks

Basically, a mobile home inspection helps you, the buyer, understand the condition of the home and any repairs to plan for before or after closing.

How does a mobile home inspection differ from a regular home inspection?

Mobile homes are built under the federal HUD Code rather than local building codes, so inspectors will look at different components than they would in a site-built home. That’s why it’s important to get an experienced inspector that is qualified to inspect your type of home.

Manufactured homes also are built using different materials, supplies, and processes, and things can shift during transport, which affect what inspectors look for. The main differences between a mobile home inspection and a regular home inspection are:

HUD-code construction

Mobile homes use unique materials and construction methods, including:

• Steel chassis.
• Factory-built floor, wall, and roof systems.
• Different plumbing and electrical layouts.

Inspectors must understand these systems to identify potential issues.

Foundation and anchoring

Instead of a traditional concrete foundation, mobile homes might rely on:

• Pier-and-beam systems.
• Anchors and tie-downs.
• Permanent engineered foundations.

Inspectors check that the support system is level, properly spaced, and securely fastened, which is necessary for safety and loan qualification.

Ventilation and moisture control

Manufactured homes are more vulnerable to moisture, especially in the enclosed underbelly. Inspectors look closely at:

• Ventilation.
• Vapor barriers.
• Under-home insulation.
• Signs of mold or rot.

Because the home was delivered to the site, the inspector checks for:

• Frame stress.
• Settlement.
• Cracks in walls or ceilings.
• Improper installation.

How much does a mobile home inspection cost?

A mobile home inspection often costs less than a full inspection on a traditional single-family home, but pricing can depend on size, location, and any add-on services. Other times, inspectors might charge a flat fee for mobile homes. A mobile home inspection will take between 2-4 hours if no additional testing is needed.

Average mobile home inspection costs:

• Single-wide: $200-$400
• Double-wide: $250-$500
• Triple-wide: $300-$600
  

You may also need:

• HUD foundation certification: $300–$600
• Pest inspection: $50–$200
• Mold or air-quality testing: $300-$650
  

A HUD foundation certification is separate from the home inspection and usually required for government-backed loans to confirm the home sits on a safe and permanent foundation.

Is a mobile home inspection required?

A mobile home inspection isn’t technically required in most states, but many lenders and insurers do require certain inspections or certifications before approving financing for a manufactured home.

Loan requirements

Government-backed loans (FHA, VA, USDA) generally require:

• A full mobile home inspection.
• Verification that the home is safely installed.
• A HUD-compliant permanent foundation certification.
• Safe electrical, plumbing, and HVAC systems.

If the home is on temporary or non-engineered piers, it will likely need foundation upgrades before it can qualify.

Insurance requirements

Some insurers require:

• A roof inspection or certification.
• Updated electrical systems.
• Proof of anchoring.
• Adequate under-home ventilation.

Common problems found during mobile home inspections

Mobile homes can develop issues not typically found (or are more pronounced than) those in traditional homes. While not all issues are cause for concern, some can affect safety, financing, insurance, and overall repair costs. Common problems manufactured home inspectors might find include:

Moisture and water damage

• Roof leaks
• Soft or sagging floors
• Damp insulation
• Damaged or missing vapor barriers

Foundation or anchoring issues

• Settling or uneven support
• Cracked or missing piers
• Outdated or improperly installed tie-downs
• Issues affecting HUD-compliant permanent foundation standards

Electrical concerns

• Outdated panels
• Aluminum wiring in older homes
• Missing GFCI protection

Roof and exterior wear

• Rust on metal roofs
• Worn or damaged shingles
• Failed sealants

Plumbing issues

• Older polybutylene pipes
• Leaks beneath the home
• Improper drainage

Bottom line

As with any home purchase, a mobile home inspection acts as critical buyer protection. Not only  does it help you understand how well the home has been maintained, but the inspection results can allow you to plan for future maintenance, and verify that it meets HUD safety and installation standards—especially if you’re using FHA, VA, or USDA financing.
