Start with the agreement, not a universal exclusion list
There is no single nationwide promise covering every US home inspection. State rules, professional standards, property type, inspector qualifications, optional services, and the signed agreement can change the scope. HUD recommends asking a prospective inspector for the applicable standard of practice or a sample report. Read both before the visit and compare them with the final report.
The current ASHI standard applies only to inspectors who subscribe to it. It describes a visual examination of readily accessible systems and says inspections under that standard are not technically exhaustive and need not identify concealed conditions or latent defects. Another inspector may work under a state rule or different standard. The buyer must verify the actual scope rather than assuming an association checklist controls.
Which physical areas can remain unresolved?
Locked rooms, stored belongings, finished surfaces, insulation, underground components, snow, vegetation, unsafe access, height, weather, disconnected utilities, seasonal equipment, and seller instructions can limit observation. Ask the report to identify why an area or component was not inspected. Determine whether lawful access, utility activation, a return visit, invasive testing, or a specialist is appropriate before the applicable deadline.
Silence is not clearance. A roof viewed from the ground is not the same scope as every surface being walked. A dry crawlspace during one visit does not prove it never receives water. Equipment that was shut down did not demonstrate operation. Preserve each limit in the inspection-report action ledger.
Which specialist services may be separate?
A general inspection may not include a sewer camera, septic evaluation, well yield or water-quality testing, radon test, wood-destroying-organism report, chimney scan, pool or spa inspection, structural design opinion, geological assessment, underground-tank work, or comprehensive lead, asbestos, mold, soil, or other environmental testing. Even when a general inspector comments on one of these areas, the comment may be only a referral.
EPA recommends property-specific radon testing and explains circumstances in which a buyer may request a new test. EPA also says it does not run a federal certification program for mold inspectors or remediation firms, while some states may have requirements. Ask which method, credential, laboratory, access, and reporting time apply; do not treat a generic air sample or visual note as a universal health conclusion.
What decisions are outside a home inspector's role?
A condition report does not establish market value, clear title, parcel boundaries, zoning, legal use, permit closure, insurance eligibility, financing approval, or the legal effect of a contract. CFPB and HUD both distinguish inspection from appraisal. Title, survey, building-authority, insurer, lender, attorney, and other qualified professionals answer different questions.
An inspector may recommend correction or further evaluation without designing the repair or stating a price. Obtain a property-specific scope from an appropriately qualified provider. Compare written estimates and check licensing and insurance where applicable; the FTC warns buyers and owners to resist pressure, review contracts, and avoid paying an entire repair price up front.
Can an inspection guarantee future performance?
No. It records observations and limitations for a defined date and scope. Systems can fail later, concealed conditions can emerge, and a component described as serviceable may still need maintenance or have uncertain remaining life. A seller repair, permit final, warranty, or reinspection also has its own scope and does not turn the entire property into a guaranteed condition.
Use the seller-repair verification guide for work promised after the report. Keep invoices, permits, warranties, photographs, specialist results, and inspector addenda attached to the original finding rather than replacing it with “fixed.”

Move open rows into the home-offer evidence worksheet. The goal is not to order every possible test. It is to identify the property-specific gap, choose the qualified person or record that can answer it, and decide before the buyer loses the relevant option.
