Mobile home inspection cost in 2026 typically runs $250 to $450 for a single-wide or double-wide manufactured home, with most buyers paying about $325 for a standard double-wide on a permanent foundation. That’s lower than a site-built home inspection of similar square footage because the inspection scope is narrower in some areas (no attic to crawl, simpler roof geometry) but broader in others (HUD compliance verification, tie-down and pier inspection, undercarriage review). This guide summarizes ASHI, InterNACHI, and HUD manufactured-home inspection conventions current as of 2026 and is general buyer guidance only — consult a licensed inspector for site-specific decisions.

How Much Does a Mobile Home Inspection Cost?

Three pricing tiers cover most situations. A single-wide manufactured home (typically 14 to 18 feet wide, 60 to 80 feet long) runs $250 to $375 in most metros. A double-wide (24 to 32 feet wide) runs $300 to $450. A triple-wide or modular home with a permanent foundation can run $400 to $600, comparable to a small site-built home inspection. Add-ons sit on top: a radon test adds $150 to $200 where applicable, a sewer-scope adds $175 to $275 if the home is connected to a municipal lateral, and a separate inspection of any attached deck, addition, or carport usually adds $50 to $150.

Two factors push the price up. First, the home’s foundation type — a HUD-tagged home on piers and ground anchors takes longer to inspect underneath than a modular home on a permanent foundation. Second, the home’s age — pre-1976 mobile homes (which predate the federal HUD Manufactured Home Construction and Safety Standards Act) often fail mortgage lender requirements outright, and an inspection of these older units takes longer because more items are non-standard. NACHI’s national average for manufactured-home inspections sits at about $350 for 2026.

What Makes a Mobile Home Inspection Different?

A mobile home inspection follows the same general structure as a site-built inspection — visual, non-invasive review of accessible systems — but the scope shifts in five specific areas. The HUD data plate and certification labels are inspected first; without these (or with painted-over or missing labels), the home may not be financeable. The undercarriage, frame, and tie-down system are inspected in detail (a site-built home has none of these). The crawl space, vapor barrier, and skirting condition are reviewed because moisture and pest entry through the underside is a recurring issue.

The roof is typically a low-slope or shallow-pitched metal or asphalt-shingle system rather than a steep-slope shingle roof, and inspectors evaluate seam integrity, vent flashings, and any post-manufacture roof-over installations. Electrical systems on manufactured homes use specific HUD standards (older homes used aluminum branch wiring more often than site-built homes of the same vintage). Plumbing in HUD-tagged homes runs PEX or polybutylene; polybutylene supply lines are a known failure point and a recurring inspection finding.

HUD Data Plate and Certification Labels

Every HUD-tagged manufactured home (built June 15, 1976 or later) has two identifying documents: a HUD certification label (a red metal tag on the exterior of each section) and a HUD data plate (a paper label inside, usually in a kitchen cabinet or near the electrical panel). The data plate records wind zone, roof load zone, thermal zone, manufacturer, and date. Lenders and insurance carriers commonly require these labels be present and legible; an inspector’s photo of each is a routine part of the report.

Foundation and Tie-Down Inspection

Manufactured homes rest on piers (steel or concrete columns) and are anchored to the ground using straps and augers — the tie-down system. The inspector verifies that piers are plumb and not crushed, that anchors meet the home’s wind-zone requirement (Wind Zones I, II, and III progress in severity), and that straps are not corroded, cut, or slack. Skirting around the perimeter should be ventilated and intact, with a vapor barrier covering the ground beneath the home. Common findings include missing or rusted ground anchors, settling piers (especially in Wind Zone I homes that were never re-leveled), and damaged skirting that has admitted pests or moisture.

A separately permitted permanent foundation (concrete block or poured-wall perimeter, full footings, removed wheels and axles) converts a HUD-tagged home to “real property” status in most states and is required for some loan types. The inspector confirms whether the conversion meets the lender’s foundation-certification standards (often referencing HUD’s Permanent Foundations Guide for Manufactured Housing). For broader buyer context on foundation-related findings, the hiring a home inspector framework helps a buyer know what specialist follow-ups to plan.

Common Findings on Mobile Home Inspections

Five findings recur across mobile home inspections regardless of metro. Polybutylene supply lines (gray plastic, common in homes built 1978 to 1995) are flagged for eventual whole-house repipe at $3,000 to $8,000. FPE Stab-Lok or Zinsco electrical panels are flagged for replacement at $1,500 to $3,500. Aluminum branch wiring in homes built before 1985 is flagged for AlumiConn or COPALUM retrofit at $1,500 to $4,000. Roof seams and vent flashings that have failed are flagged for repair at $500 to $2,500. Skirting damage and missing vapor barriers are flagged for repair at $300 to $1,500.

None of these individually disqualify a home, but a buyer should price each in before agreeing to a contract. The general inspection report is the basis for any repair-request addendum, and the buyer’s agent typically drafts the request based on the inspector’s findings. For comparison against site-built home inspection norms, the average cost of a home inspection guide covers the broader pricing context.

When to Hire a Specialist After the Inspection

Three specialist follow-ups are common after a mobile home inspection. A licensed plumber for polybutylene or aluminum-supply issues, providing a written repipe estimate. A licensed electrician for any panel replacement recommendation or aluminum branch-wiring retrofit. A foundation engineer when the inspector notes excessive settlement, soft soil under piers, or signs that the home has shifted off its anchors — common in any region with expansive soils or freeze-thaw cycles.

For homes on private well and septic systems (very common with rural mobile homes), separate well-water testing ($75 to $250) and septic inspection ($300 to $600) are standard. These are scheduled as separate appointments with separate contractors.

How to Hire a Mobile Home Inspector

Look for an inspector with manufactured-housing experience specifically — not every general home inspector is comfortable with HUD tags, undercarriage entry, and tie-down inspection. ASHI and InterNACHI both publish member directories with credentials visible. Ask three questions before booking: how many manufactured-home inspections has the inspector personally performed in the last year, will the inspector enter the crawlspace under the home (not just look at it from outside), and does the inspector provide a separate written list of the HUD data-plate and certification-label findings? An inspector who answers all three confidently is the right call.

For pre-purchase inspections, plan to attend the last hour. The walk-through covers what’s serious, what’s cosmetic, and what’s worth re-negotiating. A buyer’s repair-request addendum based on a clear written report is the cleanest path through a manufactured-home transaction. For sellers, a pre-listing inspection at the same price tier can surface issues before they kill a deal in escrow.

Skirting and Vapor-Barrier Inspection Specifics

Skirting is the perimeter material that closes off the open space between the home and the ground, and its condition matters more than buyers expect. A properly installed skirting system is ventilated — typically 1 square foot of net free vent area per 150 square feet of crawl-space floor — and includes a continuous 6-mil polyethylene vapor barrier covering the soil beneath the home. Inspectors look for four recurring issues: missing or damaged vent panels (pest entry, moisture accumulation), torn or missing vapor barrier (elevated crawl-space humidity, condensation on floor framing), pest damage at corners and access doors (rodent entry, evidence of carpenter ants or termites), and compressed or wet insulation in the floor cavity. Repairs range from $300 for spot-patch work to $1,500 for full skirting replacement with a new vapor barrier.

Crawl-space access is a recurring blocker. Some skirting systems are tightly screwed in with no proper access panel, and an inspector cannot enter without disassembling work the homeowner would prefer to leave intact. Buyers should confirm before scheduling that an access panel exists or that the seller has authorized temporary skirting removal. A skirting inspection that consists of looking through vent slots from the outside is not the same as a full undercarriage entry and should be noted as a scope limitation in the report.

Axle, Frame, and Manufactured vs. Modular Distinction

HUD-tagged manufactured homes are built on a permanent steel chassis with axles and wheels intact, even when the home is permanently installed. The chassis remains part of the structure regardless of whether the home will ever be moved again. Inspectors look at the main I-beam frame rails for corrosion, paint failure, and any signs of bending or buckling. Axles and wheels are typically checked for presence, attachment, and absence of severe corrosion; a missing axle (sometimes removed during permanent installation) is documented but does not necessarily disqualify the home for financing — the lender’s foundation engineer addresses this separately. Frame rust at the rear of the home where rainwater can pool is the most common defect and is typically a $300 to $800 cleaning-and-coating repair.

The manufactured-vs-modular distinction matters for the financing path. A manufactured home is built to the federal HUD code, carries the red HUD certification label, and remains personal property in many states unless converted via affidavit-of-affixation to real property. A modular home is built to the state or local building code (IRC), carries a state insignia rather than a HUD tag, and is treated as real property from delivery. The inspection scope differs accordingly — a modular home is inspected like a site-built home with a manufactured-section seam review, while a manufactured home requires the full HUD-tag, chassis, tie-down, and skirting protocol. Buyers should clarify which type they are buying before booking the inspection.
