What an inspector may not determine — and the federal form that disagrees

Four things, and who says so

Four determinations are outside a home inspector’s scope almost everywhere in the United States: code compliance, engineering or architectural analysis, concealed and latent conditions, and — in most jurisdictions — the remaining useful life of anything. An inspector who supplies one of them is working outside the standard they are governed by, and a report that promises one should be read with suspicion rather than relief.

These are not an individual inspector’s disclaimers. They are written into the standards and the rules. Texas, by regulation, does not require inspectors to “determine code compliance” or to “determine life expectancy of any system or component,” and does not require reporting on “anything buried, hidden, latent, or concealed.” ASHI’s general exclusions cover “the age, life expectancy or remaining useful life of systems and components” and “compliance of systems and components with past and present requirements.” InterNACHI’s standard states that an inspection “will not identify concealed or latent defects” and excludes service life expectancy, code compliance, the adequacy of any system, the cause of any condition, and the cost of repairs. Arizona’s board is blunter still: inspectors need not “calculate the strength, adequacy, or efficiency of any system” or “predict life expectancy, future conditions.”

The contradiction: a federal form against both national standards

There is one genuine, live conflict in this area, and it is not a dispute between inspectors. It is between a current federal disclosure form and every standard of practice that governs the people the form describes.

Form HUD-92564-CN, “For Your Protection: Get a Home Inspection” — revision 02/09/2023, OMB No. 2502-0538, in force until April 2029 — tells buyers that a home inspector will “evaluate its physical condition; estimate the remaining useful life of the major systems, equipment, structure, and finishes; and identify any items that need to be repaired or replaced.”

A buyer who reads the HUD notice — which lenders put in front of FHA borrowers precisely so it will be read — and then receives a report that declines to say how long the furnace has left has been set up for a complaint that is nobody’s fault. The inspector followed the standard. The lender supplied the required form. The form describes a service that the standards forbid.

Two practical consequences. First, if you were given the HUD form, do not treat the life-expectancy sentence as a specification of what you bought; read your inspection agreement and the standard of practice named in it instead. Second, if an inspector does give you remaining-life figures, understand that they are an opinion offered outside the standard, not a finding made under it — which is a reason to weigh it carefully rather than to prize it.

The same disagreement inside the severity vocabulary

The life-expectancy fault line runs deeper than one form. InterNACHI’s definition of a material defect carries an exclusion most of the industry ignores: “The fact that a system or component is near, at or beyond the end of its normal useful life is not, in itself, a material defect.”

Wisconsin’s statute says close to the opposite. Wis. Stat. 440.97(2m) defines a defect as a condition that “would significantly impair the health or safety of future occupants” or that, if not repaired, removed or replaced, “would significantly shorten or adversely affect the expected normal life of the component.” Expected normal life is the trigger in Wisconsin and an express exclusion under InterNACHI. Both cannot be applied to the same water heater.

So “it is old” is a reportable defect in one framework and expressly not one in another, and the framework that applies to your report depends on where the house is and which standard the inspector named. We map the full set of competing definitions in severity language across the states and what counts as a material defect.

Code compliance, and why the boundary is sensible

An inspector does not tell you whether a house is up to code. Texas rules exempt inspectors from determining “code compliance, utility sources, or regulatory requirements except as specifically required” by the standards, and TREC’s accompanying guidance states that “TREC does not require inspectors to inspect to any of the various building codes.” InterNACHI excludes compliance with codes or regulations. ASHI excludes compliance “with past and present requirements.” The Arizona board excludes “compliance or non-compliance with applicable codes or regulatory requirements” and, separately, “conformance with manufacturers’ installation instructions.”

The exclusion is not evasion. Codes are adopted jurisdiction by jurisdiction, amended locally, and applied as of the date of permit. A house wired correctly under the code in force when it was built is not non-compliant today; it is lawfully existing. Determining compliance would mean knowing which code edition and which local amendments applied to each piece of work — a records exercise, not a visual inspection.

What an inspector can do is report an observed condition as a hazard or a deficiency on its own terms, which is often the same practical outcome without the legal claim attached. If what you actually need to know is what a municipality signed off on, that is a permit history question and belongs with a different kind of search; what the city inspected covers that distinction.

Concealed, latent, and the limits of looking

An inspection is visual and non-invasive. It establishes the condition of what could be seen on one day, nothing more. The standards say this in almost identical words: the ASHI standard provides that inspections “are not technically exhaustive” and that the inspector is not required to identify or report “concealed conditions, latent defects, consequential damages” or “cosmetic imperfections.” InterNACHI’s standard says an inspection “will not identify concealed or latent defects.” The Arizona board’s standards say inspections “are visual, not technically exhaustive and will not identify concealed conditions or latent defects.” Texas excludes “anything buried, hidden, latent, or concealed.”

This is the source of most post-closing disappointment, and it is worth being exact about why. The failure inside the wall was not missed; it was never within the thing you bought. Where the boundary genuinely bites is in what you do about the things an inspection can see — a stain, a patched ceiling, a repainted band at the base of a wall. Those are observable, reportable, and the usual reason an inspector recommends further investigation by someone whose work is invasive.

No engineering, no adequacy, no capacity

The third boundary is the one most often crossed by a hopeful question on inspection day. An inspector reports condition. They do not calculate whether something is sufficient.

Read that list as a map of which specialist does what. It is not a list of things nobody can tell you.

Environmental hazards are excluded, and Kentucky lists them

Environmental testing is outside a general home inspection essentially everywhere, and it is bought separately when it is bought at all.

Kentucky is the most useful source here because it forces the exclusion onto the page. 831 KAR 2:030 requires reports to state the standards of practice being followed, to include a statement that the report does not address environmental hazards, and to “list all other exclusions with specificity” — with the regulation itself enumerating environmental hazards item by item through a lettered list. A Kentucky buyer therefore receives the exclusion in writing rather than inferring it.

The federal form is consistent on this point even where it is not on life expectancy. HUD-92564-CN names the conditions needing separate specialist attention: “radon; air or water quality; presence of asbestos, lead paint, or urea formaldehyde insulation; or pest infestations.” InterNACHI excludes pests, mold, fungus, airborne hazards, air quality, electromagnetic fields and hazardous waste; Arizona excludes “the presence or absence of any suspected environmental hazards” including toxins, molds and radon; ASHI excludes hazardous plants and animals, mold, fungus, asbestos and contaminants.

If you want any of these answered, order them as named services before the inspection, not as questions during it.

Who to call instead

Nearly every exclusion above has a professional attached to it. A report that says “recommend evaluation by a licensed electrician” is not deflection; it is the standard handing the question to someone licensed to answer it and insured for the answer.

What to do with this

Find out which standard governs your report. Kentucky requires inspectors to name it. Elsewhere, ask, and read the exclusions section of that standard once. It is the only document that tells you what you actually purchased.

Treat the HUD form as a notice, not a specification. If a lender gave you Form HUD-92564-CN, its advice to get an inspection is sound and its description of remaining-useful-life estimates does not match InterNACHI’s standard, ASHI’s, the Texas rules or Arizona’s. Knowing that before the report arrives prevents a dispute that would otherwise look like inspector error.

Convert exclusions into appointments. Every “recommend further evaluation” is a referral with a deadline attached. The inspection is the screening pass; the specialists are where the question actually gets answered, and your contingency period is the window in which you can still do something about the answer.

Then read the rest of the day. Our guides to what happens during a home inspection and how to read the report cover the other half — what is in scope, and how the findings that are in scope get written down.
