Two products that answer opposite questions
A home inspection tells you what is wrong with a house today. A home service contract — the product almost everyone calls a home warranty — promises to pay to repair or replace certain equipment when it breaks tomorrow. One assesses present condition. The other is a financial promise about future failure.
They get confused because they land in the same fortnight of a purchase and both get sold with the word "protection" attached. The confusion is expensive in one direction: the buyer who reads a report full of findings and assumes the warranty on the closing statement will handle them. It will not. In most contracts, the fact that the inspection found the defect is the precise reason the warranty will never pay for it.
What a home inspection is, in the words of the standards
The scope of a general home inspection is not a matter of opinion. The two bodies whose standards of practice most inspectors work to say the same restrictive things.
InterNACHI defines a home inspection as "a non-invasive, visual examination of the accessible areas of a residential property… designed to identify defects within specific systems and components." ASHI's runs parallel: the inspector "visually examines the readily accessible systems and components of a home." Readily accessible is itself defined — visible without moving personal property, dismantling, or destructive measures. To inspect means operating normal operating controls and opening readily openable access panels. Nothing more.
Three limits do the real work, and each cuts against the idea that an inspection protects you from future cost:
- Not technically exhaustive. No dismantling, no advanced instrumentation, no extended testing. A furnace gets operated by its normal controls; it does not get taken apart.
- A dated snapshot. InterNACHI states the inspection "is based on the observations made on the date of the inspection, and not a prediction of future conditions," and "will not reveal every issue that exists or ever could exist."
- Not a forecast, not a guarantee. Under ASHI's general exclusions the inspector is not required to determine remaining life expectancy, not required to determine future conditions including the failure of systems and components, and not required to offer warranties or guarantees.
The thing buyers most want — a reliable answer to "how long before this has to be replaced" — is exactly what the standards say the inspector does not have to give.
What a home service contract is, in the words of the statutes
The warranty side is defined by statute rather than by a standards body, and the definitions describe the mechanism instead of marketing it.
California's Home Protection Law defines a home protection contract as one under which a person, other than a builder, seller or lessor, undertakes "for a specified period, for a predetermined fee, to repair or replace all or any part of any component, system or appliance of a home necessitated by wear and tear, deterioration or inherent defect" — and it excludes consequential damages. Florida reaches the same product as a service warranty: a contract of at least a year covering the cost of repair, replacement or maintenance of a consumer product.
Federal warranty law explains why this is not a "warranty" in the ordinary sense at all. Under the FTC's Magnuson-Moss interpretations, an agreement calling for consideration in addition to the purchase price, or entered into after the purchase, is a service contract rather than a written warranty. You pay separately, later, for someone else's promise to fix things.
Three consequences follow, and they are the ones buyers miss:
- The trigger is failure, not condition. A component that is old, noisy, inefficient or out of step with current code, but still operating, produces no claim.
- The trigger is a specific cause. Wear, deterioration, inherent defect — not impact, weather, misuse, neglect, rodents or power surge.
- The remedy is the equipment, not the damage. The failed part is the obligation; what it ruined is not.
The two products, side by side
| Home inspection | Home service contract ("home warranty") | |
|---|---|---|
| Time orientation | Present condition, on one dated day | Future failure, during a defined term |
| Scope | The whole readily accessible house: structure, roof covering, exterior, grading, and the visible parts of every system | An enumerated list of systems and appliances, and within each, an enumerated list of parts |
| Who pays, and when | Usually the buyer, at the time of service, out of pocket | A premium, often paid at closing as a seller concession, plus a trade service call fee per visit |
| Roof, foundation, structure | Reported on, within visual limits | Normally excluded, or reduced to a narrow leak-repair rider |
| Cosmetic and code issues | Code compliance sits outside the standard; safety and material defects are reported | Excluded, and code-required upgrades are excluded even when the repair is covered |
| Pre-existing problems | Finding them is the entire point | Excluded — and the finding is the evidence |
| Duration | Hours. The report is a fixed record of that day | Typically one year, renewable, with a waiting period at the start |
| When you must act | Inside the inspection, option or due diligence period, which expires | Any time — but coverage starts only after the effective date and any waiting period |
| If it goes wrong | A claim against the inspector, usually against a limitation of liability | A breach of contract claim, usually against an arbitration clause |
| Who regulates it | State inspector licensing boards, where the state licenses inspectors at all | Varies by state: an insurance department, a warranty regulator, a licensing agency, or nobody |
Who pays, when, and whose interests each document serves
The inspection. The buyer orders and pays for it, usually at the time of service and out of pocket rather than out of escrow. The engagement is between buyer and inspector, which is why the report belongs to the buyer and the inspector's duty runs to the buyer. Where a seller commissions a pre-listing inspection instead, the client relationship flips, and a buyer relying on that report relies on a document produced for someone with an opposing interest.
The warranty. The premium is annual, sometimes billed monthly, and in a resale it is very often paid at closing as a negotiated seller concession. On top of it sits the trade service call fee — the flat amount the homeowner pays the dispatched contractor per visit regardless of the repair cost and, in most contracts, of whether the claim is approved.
The incentives are worth stating plainly, without accusing anyone of bad faith. The inspector is paid once, the same whether he finds nothing or forty things, and his exposure comes from missing something — which pushes toward reporting more. The administrator is paid up front and pays out later, so every authorised repair reduces margin — which pushes toward reading exclusions carefully. Neither structure is sinister; they simply do not point the same way.
What each one actually detects
An inspection detects symptoms. Staining, corrosion, scorching, active drips, improper installation, defeated safety devices, unsafe wiring practices, water at the foundation, a roof covering at the end of its serviceable condition. It covers the whole house, including categories a service contract will never touch: structure, foundation, drainage, windows, exterior cladding.
What it cannot detect is equally defined: concealed and latent defects, anything behind a finished surface, anything underground, anything requiring dismantling, and above all the timing of a future failure. A twelve-year-old furnace that lights, cycles and holds temperature on inspection day passes. It may still fail in November.
A service contract detects nothing at all. There is no underwriting inspection in the standard product — nobody walks the mechanical room, photographs the condenser or records serial numbers, which is why a plan can be issued in minutes. The contract is a payment mechanism that activates when a homeowner reports the breakdown of an enumerated item. Its "coverage of the plumbing system" is in practice coverage of a listed set of components within it, and parts off the list fall outside the grant of coverage before any exclusion is reached.
The missing underwriting is made up at claim time, where the two products collide.
Why the warranty will not pay for what the inspection found
Every home service contract carries a pre-existing condition exclusion, and it decides most contested claims. Published contracts draft it two ways.
The blunt version excludes pre-existing conditions outright, known or unknown, paired with a condition precedent that covered items be in proper working order on the effective date. Under that drafting the administrator need not prove the homeowner knew anything; it only has to establish that the condition predated coverage.
The more common version looks generous and is not. It covers an unknown pre-existing failure provided the failure could not have been detected by visual inspection or simple mechanical test. That is not a knowledge standard. It is an objective detectability standard: the question is not what the homeowner knew, but whether a reasonable look or a basic operational test would have revealed the condition.
Now line that up against the product on the other side of this page. A general home inspection is a visual examination with simple operational testing — the exact procedure the exclusion describes. So when an inspector documents a rusted evaporator coil, a weeping water heater fitting, a double-tapped breaker or a short-cycling compressor, the report does not merely describe a problem. It supplies contemporaneous written proof, dated before the effective date and produced by a professional the buyer hired, that the condition satisfied the exclusion's own test.
This is the product working as drafted and priced, not a company behaving badly. A one-year premium is not calculated to replace equipment already failing when the plan was sold. The corollary is uncomfortable: a thorough report makes a later claim harder on the items it flagged.
How an inspection report ends up inside a claim file
Buyers assume the report is private; in a financed resale it usually is not. Copies proliferate: the buyer's agent's transaction file, the seller's file if the report accompanied a repair request, the repair addendum itself, invoices for resulting work. A signed repair amendment is the most damaging, because it records that a specific defect existed on a specific date and that both parties priced it.
At claim time the administrator does not need to subpoena anything. It asks. Requests for maintenance records, prior service invoices and the purchase-time report are routine in a contested-claim workup, and refusing to produce documents while asking the other party to pay is not negotiating from strength.
There is a version that runs the other way, and it is the useful one. Where a flagged defect was actually repaired before closing, the paperwork proving it — the licensed contractor's invoice, the parts detail, the permit and sign-off where required — converts the most adverse document in the file into the most favourable one.
A closing credit taken in lieu of repair leaves the finding standing and unremedied. The defect is now documented, dated, unrepaired, and known to the person who will file the future claim. Whatever its merits at the negotiating table, it is the worst available paper trail for warranty purposes.
The order these two things happen in, and which one has a deadline
Sequence matters more than either product does alone, because only one half of the pair sits inside a window that closes.
- Contract executed. The inspection, option or due diligence period starts running, and in most standard forms runs on calendar days.
- Inspection ordered immediately, not mid-period. Specialty inspections — sewer scope, wood-destroying insect, septic, pool, structural — are separate engagements with their own lead times, each triggered by something the general inspection reports. Order late and there is no room for the specialty inspection it points to.
- Report delivered, findings triaged. Separate safety and structural items from deferred maintenance, and get trade quotes on anything you will negotiate.
- Written repair request, renegotiation, or termination — before the period expires. This is the whole remedy. Once the period ends, a defect the buyer knows about is simply a house the buyer agreed to buy.
- Warranty selected and paid, commonly at closing, where it is a line item and negotiable like any other concession.
- Effective date, then the waiting period. Plans bought outside a real estate transaction commonly impose a waiting period of roughly thirty days; plans issued as part of a sale frequently start at closing. Which applies is answered in the contract, not by the salesperson.
The asymmetry is the lesson. The inspection is the only one of the two with leverage attached, and the leverage evaporates on a date printed in the purchase agreement. The warranty can be bought next month. The right to walk away over a cracked heat exchanger cannot.
What neither product is
Both get confused with a third thing. Homeowners insurance responds to sudden accidental physical loss from a covered peril and pays for resulting damage. A home service contract responds to mechanical failure of enumerated equipment from wear, deterioration or inherent defect, and does not pay for resulting damage. A home inspection pays for nothing at all; it produces information, and information is worth something only while a contingency period is open.
Neither is a code compliance certificate, and neither guarantees the house. Nor do they substitute for one another — a buyer who skips the inspection because a warranty is included has traded a broad look at the whole house for a narrow, capped promise about a list of appliances, and handed the pre-existing condition exclusion an undefended field.
The scope documents are public: inspection scope from InterNACHI and ASHI, and the federal line between a written warranty and a service contract at 16 CFR 700.11. Reading them takes under an hour. None of it is legal advice, and state law varies.
Frequently Asked Questions
Do I need a home inspection if the seller is providing a home warranty?
They do not substitute for one another. The warranty covers a list of mechanical items against future breakdown and says nothing about the roof, foundation, grading, windows, wiring practices or safety defects a general inspection exists to find. It also will not pay for anything already failing when the plan took effect.
The larger problem is timing. A warranty can be bought at any point; an inspection has value only while the contingency period is open, because that period is what converts a finding into leverage.
Does a home warranty company inspect the house before selling a plan?
In the standard consumer product, no. There is normally no underwriting visit, no equipment survey and no record of serial numbers, which is why plans can be issued in minutes. Some contracts reserve a right to inspect, but it is rarely exercised at the point of sale.
The underwriting still happens; it is deferred to claim time and performed by the exclusion list instead. The waiting period and the pre-existing condition clause do the work an underwriting inspection would otherwise do.
Will the warranty company ask to see my home inspection report?
On a contested claim, frequently. Requests for the purchase-time report, prior service invoices and maintenance records are routine when investigating whether a failure was pre-existing, and the report is the most useful document the administrator can obtain: written by a professional, dated before coverage, describing exactly what a visual inspection revealed.
Declining to produce it rarely helps, since refusing to substantiate a claim while asking the other party to pay tends to end the discussion. The stronger position is proof that a flagged item was later repaired by a licensed contractor.
Who pays for the home inspection, and who pays for the home warranty?
The buyer normally pays the inspector directly, at or near the time of service, and it is not usually rolled into closing costs. The buyer is the client, which is why the report and the duty of care both run to the buyer.
The warranty premium is more often negotiated, and in a resale it is commonly offered by the seller as a concession appearing at closing. Who pays does not change what the contract covers; the same exclusions, caps and waiting period apply.
Can an inspector tell me how many years my air conditioner has left?
He is not required to. Under the published standards of practice the inspector is specifically not required to determine remaining life expectancy, or to determine future conditions including the failure of systems and components. An inspector who gives a confident number is stepping outside the standard.
What an inspection legitimately provides is the date of manufacture from the data plate, present observable condition, and symptoms visible on the day. Those are budgeting inputs, not a prediction, and no warranty product converts them into one.
The inspection found a problem and the seller fixed it. Is it covered now?
It is in a far better position, and the paperwork decides it. A licensed contractor's invoice identifying the replaced parts, dated before closing, plus a permit and sign-off where applicable, establishes that the condition was remedied rather than carried forward. A later claim then concerns a repaired component.
Where the parties agreed a credit instead, the position is worse: the finding stands unremedied, dated and documented, which is precisely what a pre-existing condition exclusion runs on. Nothing prevents a homeowner doing the repair after closing and keeping the invoice.
