Manufactured Home Specific

Every System, Inspected Thoroughly

Manufactured homes have systems you won't find in site-built construction. I inspect all of them, in addition to every standard system a conventional home inspection covers.

Structure

Chassis and Foundation

I inspect the steel chassis for rust, deflection, and damage. Piers, blocking, and tie-down anchors are checked for proper spacing, corrosion, and compliance. This is the foundation of manufactured home safety.

Regulatory

HUD Data Plate Verification

Every HUD-code manufactured home is required to carry a data plate listing its wind zone, thermal zone, and roof load zone. I verify the plate is present, legible, and matches the home. Lenders routinely require this.

Moisture

Belly Board and Vapor Barrier

The belly board seals the underside of the home from moisture and pests. Tears, repairs, and failed sections allow ground moisture to reach floor framing, leading to soft floors and decay. I probe and document every accessible area.

Multi-Section

Marriage Wall Connections

Double-wide and triple-wide homes are joined at the marriage wall. Gaps, failed seals, and separated sections are common failure points that allow water intrusion and structural movement. I inspect the full marriage line from inside and out.

Electrical

Electrical Systems

I inspect the main panel, breakers, wiring, outlets, and GFCI protection. Older manufactured homes often have aluminum branch wiring or undersized panels that present fire and safety risks. I document every deficiency clearly.

Plumbing

Plumbing and Water Heater

Supply lines, drains, water heater condition, and exterior connections are all inspected. Belly-routed plumbing in manufactured homes is especially vulnerable to freeze damage and rodent intrusion. Thermal imaging helps reveal leaks invisible to the eye.

Thermal

Thermal Imaging Included

Every inspection includes a full thermal imaging scan. In manufactured homes this is especially valuable for locating moisture behind walls, insulation gaps, and hidden electrical heat. It costs extra everywhere else. Not here.

Roof

Roof and Attic

Manufactured home roofs often feature low-slope or flat areas with rubber membrane or metal roofing. I inspect the field, seams, penetrations, and attic or ceiling cavity for moisture damage, ventilation deficiencies, and structural concerns.

Report

Detailed Digital Report

Your report is photo-rich and written in plain language with severity ratings on every finding. Most reports are delivered the same day. You get a clear picture of the home's condition before you make a decision.

Common Deficiencies

What Goes Wrong in Manufactured Homes

After thousands of inspections and 12 years of construction experience, these are the issues I find most often in manufactured homes across the Portland metro and SW Washington.

01

Soft or Spongy Floors

The most common complaint in older manufactured homes. Tears in the belly board let ground moisture reach the particle board subfloor. Once particle board gets wet, it swells, loses structural integrity, and eventually fails. I find this in over half of manufactured homes built before 2000.

02

Missing or Corroded Tie-Downs

Anchoring systems deteriorate over time. Straps rust, anchors pull out of the ground, and many older homes were never anchored to current standards. This is a safety issue, not just a code issue. Both Oregon and Washington have specific anchoring requirements for manufactured homes.

03

Failed Marriage Wall Seals

The seam where two sections of a double-wide meet is a persistent weak point. Sealants fail, the structure shifts, and water finds a path in. Interior water staining at the ceiling centerline is a red flag. I inspect the full marriage line and document every failure.

04

Undersized or Outdated Electrical Panels

Older manufactured homes were often built with 60-amp or 100-amp service that cannot support modern household demand. Some panels were manufactured brands with documented safety deficiencies. I test every circuit and document what needs upgrading.

05

Improper Pier Spacing and Settlement

When piers are spaced too far apart, the chassis can deflect between support points. Settlement shifts piers out of position. Doors and windows that stick or gaps in wall trim often trace back to pier issues. I measure pier spacing and document any deflection or settlement.

06

Missing HUD Data Plate

The HUD data plate is a permanent record of how the home was designed and built. It is required by most lenders for financing. Missing plates complicate sales and refinancing. I note its location and condition in every inspection report.

Your Inspector

While I Was Building Homes, I Was Also Inspecting Them

I didn't transition from construction to inspection. I did both at the same time. For 12 years I held an active CCB license as a General Contractor while building my inspection career. That means when I find a problem in a manufactured home, I can tell you what it costs to fix it, what a repair actually looks like, and whether the concern is cosmetic or structural.

Manufactured home inspections require specific knowledge that general home inspection training doesn't fully cover. HUD Code is not the same as Oregon or Washington building code. I know the difference, and I apply that knowledge on every manufactured home inspection I perform.

Common Questions

Manufactured Home Inspection FAQ

Answers to the questions I get most often from buyers and agents.

Manufactured homes are built to HUD Code rather than local building codes. The inspection focuses on systems unique to manufactured construction: the steel chassis, marriage wall connections for multi-section homes, pier-and-tie-down anchoring, belly board condition, vapor barrier integrity, and HUD data plate verification. I also evaluate all standard systems including roof, electrical, plumbing, and HVAC.
The HUD data plate is a permanent label affixed inside every HUD-code manufactured home. It lists the manufacturer, model, wind zone, thermal zone, and roof load zone the home was built to meet. Lenders and insurers often require it. I verify the data plate is present and readable during every manufactured home inspection.
Yes. I visually inspect all accessible tie-downs, ground anchors, and straps for corrosion, improper installation, and missing components. Proper anchoring is a safety-critical system and a common deficiency in older manufactured homes in both Oregon and Washington.
Yes. I am licensed in both Oregon (OCHI #1898) and Washington (DOL #1856) and inspect manufactured homes throughout Clark County, including Vancouver, Camas, Washougal, Battle Ground, and Ridgefield.
Yes. Radon testing can be added to any inspection, including manufactured homes. With an inspection, radon testing is $150. A standalone radon test is $195. Combo pricing always saves you money.
Pricing follows the same square footage schedule as single-family homes, starting at $395 for homes up to 1,500 sq ft. Thermal imaging is included at no extra charge. Call (971) 202-1311 or book online for a specific quote.
The biggest concerns are soft floors from belly board moisture damage, chassis rust or deflection, failed marriage wall seals in multi-section homes, improper pier spacing, deteriorated vapor barriers, and outdated electrical panels. A professional inspection covers all of these and gives you a clear picture of what you are buying before you commit.
I recommend arriving for the last 30 minutes of the inspection. This lets me work without interruption and then do a focused walkthrough to show you the key findings in person. You leave with a clear understanding of the home's condition, not just a report to decipher on your own.
