Considering downsizing, purchasing your first home, or seeking an affordable option in a competitive market? A mobile or manufactured home could be the perfect solution. However, due to their unique construction and installation methods, a mobile home inspection is a crucial step in the buying process.
Manufactured homes must adhere to federal Housing and Development (HUD) construction standards, such as being situated on steel frames and utilizing anchored or permanent foundation systems for stability and security.
Many financing options like FHA, VA, or USDA loans may require a mobile home inspection. Lenders may request both an inspection and a HUD-compliant permanent foundation certification before approving the loan, as the safety and installation of the home directly impact financing eligibility.
Understanding the mobile home inspection process is essential for buyers, whether you’re purchasing a mobile home in Portland, OR or exploring 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, before HUD standards were introduced.
- A manufactured home is a factory-built home constructed after June 15, 1976, meeting federal HUD Code requirements for safety, installation, and construction quality.
- While many people refer to both as “mobile homes,” most available houses today are technically classified as manufactured homes.
What does a mobile home inspection include?
A mobile home inspection typically focuses on areas unique to manufactured homes. Inspectors will assess safety concerns, signs of damage, and issues that could impact the home’s long-term stability or financing eligibility, with a special emphasis on components specific to manufactured homes.
Key areas covered in a mobile home inspection include:
Structural support and foundation
- Steel chassis and frame
- Piers, blocks, and footings
- Anchoring or tie-down system
- Condition of vapor barrier and underbelly
- Evaluation of installation on a permanent foundation*
*Inspectors verify if the installation meets HUD guidelines for permanent foundations.
Roof and exterior
- Roof covering and sealants
- Siding, skirting, and under-home ventilation
- Gutters, flashing, and drainage
- Identification of moisture intrusion signs
Plumbing
- Pipe materials (PEX, CPVC, or older polybutylene)
- Water pressure and drainage
- Hot water heater condition
- Inspection for leaks under sinks, fixtures, or beneath the home
Electrical
- Assessment of service panel condition
- Verification of proper grounding
- Check for GFCI protection
- Confirmation of safe wiring materials
Heating and cooling
- Evaluation of furnace operation and age
- Assessment of air conditioning function
- Examination of ductwork and airflow
Interior systems
- Identification of soft or uneven floors
- Assessment of window and door functionality
- Recognition of ceiling stains, wall cracks, or signs of leaks
In essence, a mobile home inspection provides buyers with insights into the home’s condition and necessary repairs, both pre and post-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, resulting in inspectors assessing different components compared to site-built homes. It’s crucial to engage an experienced inspector qualified to inspect your specific type of home.
Manufactured homes utilize distinct materials, supplies, and processes, with potential shifts during transport impacting inspection criteria. The primary differences between a mobile home inspection and a standard home inspection include:
HUD-code construction
Mobile homes incorporate unique materials and construction methods, including:
- Steel chassis
- Factory-built floor, wall, and roof systems
- Different plumbing and electrical layouts
Inspectors must be well-versed in these systems to identify potential issues.
Foundation and anchoring
Unlike traditional concrete foundations, mobile homes might rely on:
- Pier-and-beam systems
- Anchors and tie-downs
- Permanent engineered foundations
Inspectors verify that the support system is level, properly spaced, and securely fastened, essential for safety and loan qualification.
Ventilation and moisture control
Manufactured homes are susceptible to moisture, especially in the enclosed underbelly. Inspectors closely examine:
- Ventilation
- Vapor barriers
- Under-home insulation
- Signs of mold or rot
Transport-related issues
Given the home’s delivery to the site, inspectors check for:
- Frame stress
- Settlement
- Cracks in walls or ceilings
- Improper installation
How much does a mobile home inspection cost?
A mobile home inspection typically costs less than a full inspection on a traditional single-family home, with pricing varying based on size, location, and additional services. In some cases, inspectors may charge a flat fee for mobile homes, with inspections lasting between 2-4 hours if no further testing is required.
Average mobile home inspection costs:
- Single-wide: $200-$400
- Double-wide: $250-$500
- Triple-wide: $300-$600
Additional services may include:
- HUD foundation certification: $300–$600
- Pest inspection: $50–$200
- Mold or air-quality testing: $300-$650
A HUD foundation certification, separate from the inspection, is typically necessary for government-backed loans to ensure the home is on a safe and permanent foundation.
Is a mobile home inspection required?
While a mobile home inspection isn’t mandatory in most states, many lenders and insurers demand specific inspections or certifications before approving financing for a manufactured home.
Loan requirements
Government-backed loans like FHA, VA, USDA loans generally mandate:
- A comprehensive mobile home inspection
- Verification of safe installation
- A HUD-compliant permanent foundation certification
- Secure electrical, plumbing, and HVAC systems
If the home is on temporary or non-engineered piers, it may require foundation upgrades for qualification.
Insurance requirements
Some insurers may request:
- A roof inspection or certification
- Updated electrical systems
- Proof of anchoring
- Adequate under-home ventilation
Common problems found during mobile home inspections
Mobile homes may experience issues uncommon in traditional homes or more pronounced than usual. Although not all issues are alarming, some can impact safety, financing, insurance, and repair costs. Common problems identified during manufactured home inspections include:
Moisture and water damage
- Roof leaks
- Soft or sagging floors
- Damp insulation
- Missing or damaged vapor barriers
Foundation or anchoring issues
- Settling or uneven support
- Cracked or missing piers
- Outdated or incorrectly installed tie-downs
- Issues affecting HUD-compliant permanent foundation standards
Electrical concerns
- Outdated panels
- Aluminum wiring in older homes
- Lack of GFCI protection
Roof and exterior wear
- Rust on metal roofs
- Worn or damaged shingles
- Failed sealants
Plumbing issues
- Older polybutylene pipes
- Under-home leaks
- Improper drainage
Bottom line
Similar to any home purchase, a mobile home inspection is essential for buyer protection. It not only provides insights into the home’s maintenance history but also enables you to plan for future repairs and confirms compliance with HUD safety and installation standards, particularly when utilizing FHA, VA, or USDA financing.
