The buyer's inspection

This is the standard inspection, at its standard moment

A buyer's inspection is the ordinary home inspection, performed to the ordinary scope, at the moment the industry was built around: after an offer is accepted and before the contract's inspection or option deadline expires. Nothing about the occasion alters the product. This page is the baseline; the other fifteen occasions are departures from it.

What makes the moment standard is not the inspection but the position the buyer occupies while it happens. The buyer has a signed contract, a deadline, and a contractual right to act on what the report says. The inspection supplies facts; the contract supplies the remedy. Commission the identical inspection a week earlier, as a pre-offer inspection, and the facts are the same while the remedy is gone.

The Consumer Financial Protection Bureau's homebuyer booklet puts the relationship plainly: the inspector “works for you and should tell you whether the home you want to buy is in good condition and whether you are buying a 'money pit' of expensive repairs.” Worth holding onto when the report arrives through an agent's inbox.

What the scope covers

The scope is written down — in a state administrative rule, or in one of the two national standards of practice — and those documents are short, public, and almost never read by the person paying for the inspection.

The ASHI standard organizes the inspection into seventeen numbered sections, running from structure, exterior, roofing and plumbing through electrical, HVAC, interior, insulation, venting, fireplaces and the garage, and closing with general limitations and exclusions. The InterNACHI residential standard covers the same ground and states its own boundary: it applies to “properties with four or fewer residential units.” A duplex is inside it; a twelve-unit building is a commercial engagement under a different standard.

Within each section the standard sets a floor, and the floor sits lower than buyers assume. The inspector must examine roof coverings, gutters, flashing, skylights and chimney penetrations and report an active leak — but need not walk the roof, water-test it, or certify it. The inspector runs water, flushes toilets and inspects the water heater and main shut-offs — but need not measure capacity, temperature, age or adequacy, determine flow rate or pressure, or inspect a septic system. The inspector examines the service, panel, overcurrent devices, grounding and representative receptacles and must report missing smoke and carbon monoxide detectors and solid aluminum branch wiring — but may not put a probe in the panel, operate a breaker, or measure amperage or voltage. The requirement is to look thoroughly and report honestly on what looking reveals; it is not to measure, to test to destruction, or to predict.

What is excluded by rule, not by oversight

The commonest complaint about a report is that it failed to mention something discovered three months after closing. In a large share of those cases the inspector did nothing wrong, because the thing was outside the scope by written rule.

The ASHI general limitations state that inspections under the standard “are not technically exhaustive” and need not identify or report “concealed conditions, latent defects, consequential damages” or “cosmetic imperfections.” The general exclusions then remove four judgments buyers most want: the age, life expectancy or remaining useful life of a system; compliance with past and present requirements; market value and marketability; and the presence of mold, fungus, asbestos and contaminants. Engineering services and warranties are excluded too, and InterNACHI's list adds the adequacy of any system, the cause of any condition, future conditions, code compliance, pests, air quality and the cost of repairs.

States say it in their own voice. Texas provides that the inspector need not determine code compliance or life expectancy and need not report on “anything buried, hidden, latent, or concealed,” and the commission's guidance adds that it “does not require inspectors to inspect to any of the various building codes.” Arizona's board standard excludes “the methods, materials and costs of corrections” and any attempt to “predict life expectancy, future conditions, including but not limited to failure of components.”

An inspector who declines to price a repair is complying with the standard rather than dodging. And whether a previous owner's garage conversion was permitted is not an inspection question at all — that is a municipal records question, and a city inspection is a different thing from a private one.

The appraisal does not do this job

The most expensive misunderstanding in a residential purchase is the belief that the lender's appraisal is a condition check. It is not, and the federal government says so on a form the buyer signs. Form HUD-92564-CN, For Your Protection: Get a Home Inspection, carries the heading “Appraisals are NOT Home Inspections!” and states that “An appraisal is required to estimate the home's value for your lender and does not replace a home inspection.” The same form defines the inspection's purpose — “to inform and educate you about the property before you make a financial commitment” — and removes the backstop buyers imagine: “FHA does not guarantee the value or condition of your new home. If you find problems with your home after closing, FHA cannot give or lend you money for repairs, and FHA cannot buy the home back from you.” That applies to FHA-insured purchases specifically.

The form is not an industry pamphlet. Congress wrote it into federal law. Under 12 U.S.C. § 1701x–1, enacted as section 1451 of the Dodd-Frank Act, HUD must publish the form and its companion materials in English and Spanish, and FHA-approved lenders must put them in a buyer's hands “at first contact, whether upon pre-qualification, pre-approval, or initial application.” An FHA buyer who has never seen the form was not given something the law requires. The CFPB states the distinction as two people rather than two documents: the appraiser is “an independent professional whose job is to give the lender an estimate of the home's market value.” Two clients, two questions, and neither answers the other's.

The contingency is what gives the findings leverage

A report is information. A contingency is what converts information into a decision somebody else has to respect. Without one, a buyer who finds a serious defect on day nine has learned something expensive and can do nothing with it but pay or forfeit a deposit.

The clause itself is unremarkable prose. The Minnesota Attorney General's office publishes a sample buyer's contingency conditioning the purchase on a report stating that the house is “structurally sound and in good repair” and its mechanical, electrical, heating, sewer, water and plumbing systems “in proper working order” — and providing that if the buyer is not satisfied the agreement “shall become null and void at the option of and upon written notice by Buyer, in which case the earnest money shall be refunded to Buyer.” The document is undated, but the language is a state law office's own rather than a brokerage form.

Texas runs the same machinery through two paragraphs of a promulgated state contract, and they do different jobs. One grants “the unrestricted right to terminate this contract by giving notice of termination to Seller within ___ days after the Effective Date” — the option period, during which a Texas buyer may terminate for any reason at all. The other requires the seller to “permit Buyer and Buyer's agents access to the Property at reasonable times.” One creates the right to look; the other creates the right to leave.

No state located in our research sets a statutory number of days. The Texas form leaves the option period blank. North Carolina's commission describes the due diligence period only as “a negotiable period of time.” Massachusetts specifies “a reasonable period of time ... as agreed to by the Seller and the Buyer.” Articles telling you that your state gives you seven days are describing local custom and calling it law.

Massachusetts has gone further: under 760 CMR 74.03(1), effective 6 June 2025, a seller or their agent “shall not condition the acceptance of an offer to purchase ... on the Prospective Purchaser's agreement to waive, limit, restrict or otherwise forego a Home Inspection.” That is routinely reported backwards. It restricts what a seller may demand; it does not forbid a buyer from choosing to skip the inspection, and auctions are exempt.

What the report is for, and what no source can tell you

The report records condition observed on one day by one person working to a published standard. HUD's description — to “inform and educate you about the property before you make a financial commitment” — is the most accurate short statement available anywhere, and it is pointedly not “a list of items the seller must fix.” The report is raw material for three decisions — proceed, renegotiate, terminate — and which one the findings support is the buyer's judgment. Our guide to reading the report covers severity language and the summary page.

Two things the rest of the internet states with more confidence than the evidence allows. First, there is no primary source for how long an inspection takes or how long the report runs. No federal agency collects it and no state board publishes it. The best evidence located is a 2018 undercover test of twelve inspectors in one metro area by a nonprofit consumer research publisher: three were “in and out in 90 minutes, compared to 2.5 hours or longer for a few others,” reports ran as short as ten and fourteen pages, and against twenty-eight problems the testers had planted the group “caught these problems only half the time.” An illustration, not an average — and the only measurement anyone has published.

Second, nobody publishes how often inspections kill deals. The REALTORS® Confidence Index has reported about 5% of contracts terminated in every December edition from 2021 through 2025, but it breaks out only appraisal issues as a cause and publishes no inspection-specific share. Nor does any government, GSE or academic source publish a figure for post-inspection repair requests.

What to do with the inspection once you have it

Three things decide whether the money was well spent, and all three happen around the inspection rather than during it.

Know the contract deadline before the inspector is booked. It is a contract term, not a statutory right, and it is short. Texas convention treats the effective date as day zero and requires written termination notice by 5 p.m. local time on the last day of the option period; the option fee itself is never refundable. Other states count differently; the only deadline binding you is the one in your document.

Be there. Massachusetts's licensing agency tells consumers to attend in order to “observe the inspector, ask questions directly, and obtain a better understanding of the condition of the home.” A state regulator saying so carries more weight than an inspector saying so, and an hour in an attic with the person writing the report is the cheapest technical education a buyer will get. The inspection day guide covers what to expect.

Decide what the report is for before you read it. If the findings are the ordinary accumulation of a lived-in house, the report has done its work by establishing that. If they are not, the choice is between a price adjustment, a repair demand and walking — and the clock on all three is the contingency deadline. If the house is sold as-is, or you are weighing an inspection before you have a contract at all, those pages set out how the arithmetic changes.
