What Are Building Inspectors Not Allowed to Do?

Home inspectors are not allowed to move your belongings, turn on utilities that are shut off, open walls or pull up flooring, test for environmental hazards like mold or radon, examine specialized systems such as wells and septic, judge whether the home meets building codes, estimate repair costs, or do repair work on a home they recently inspected. Understanding what home inspectors are not allowed to do is the difference between a report that quietly leaves gaps and a purchase where you know exactly which specialists to hire alongside the general inspection.

The limits come from two industry standards: the American Society of Home Inspectors (ASHI) Standard of Practice and the International Association of Certified Home Inspectors (InterNACHI) Standards of Practice. Both describe a home inspection as a visual review of readily accessible, installed systems, and both state the inspection is “not technically exhaustive.”1American Society of Home Inspectors. ASHI Standard of Practice for Home Inspections 2026 A quick boundary worth stating: a private home inspector is not a municipal building inspector. Code enforcement, permits, and legal compliance determinations belong to the government official, not the person you hire for your transaction.

Physical Actions a Home Inspector Cannot Perform

Several restrictions apply to what the inspector can actually do once on the property. These exist to prevent damage, protect everyone’s safety, and keep the inspection non-invasive.

Moving Furniture, Storage, or Anything in the Way

Inspectors cannot move furniture, stored boxes, rugs, ceiling tiles, window coverings, plants, debris, or any other personal items that block their view.2International Association of Certified Home Inspectors. InterNACHI Standards of Practice for Performing a General Home Inspection A basement wall hidden behind shelving gets noted as “not inspected” rather than examined. If the electrical panel, furnace, or water heater is blocked when the inspector arrives, those components may not get looked at. Clear access before the appointment, because the inspector won’t do it for you.

Turning On Shut-Off Utilities

If the electricity, water, or gas is shut off, the inspector leaves it that way. The 2026 ASHI standard specifically states inspectors are not required to “turn on any utilities such as the electric, water or gas” or “ignite or extinguish fires, pilot lights, burners, and other open flames that require manual ignition.”1American Society of Home Inspectors. ASHI Standard of Practice for Home Inspections 2026 The same goes for shut-off valves, manual stop valves, safety controls, and remote-controlled devices.

The reasoning is practical. Turning on water in a vacant home can trigger a hidden plumbing leak and flood the property. Activating a gas line without knowing its condition is a safety hazard. If utilities are off when you schedule the inspection, arrange with the seller or utility company to have them turned on first. Otherwise, those systems go unexamined.

Entering Areas They Judge Unsafe

Inspectors can decline to enter any area they consider hazardous. Crawl spaces with less than 24 inches of clearance, attics where insulation covers structural framing, and any space that poses a risk of injury or property damage can all be skipped.3American Society of Home Inspectors. ASHI Standard of Practice for Home Inspections The report should note what was skipped and why.

Any Form of Destructive Testing

Opening walls, pulling up flooring, digging around foundations, and dismantling components are off-limits. The inspection is non-invasive by rule. When an inspector suspects a problem behind a finished surface, such as water staining that hints at a hidden leak, the report recommends further evaluation by a specialist. No on-the-spot demolition, no exploratory cutting.

Systems and Conditions Outside the Scope

Several property systems sit entirely outside a general home inspection. If any of these matter to you, hire a separate specialist.

Environmental Hazards Are Explicitly Excluded

This is the gap that catches the most buyers off guard. A general home inspection does not cover any environmental hazard, including mold, radon, asbestos, lead-based paint, or pest infestations.4International Association of Certified Home Inspectors. InterNACHI Standards of Practice for Performing a General Home Inspection The 2026 ASHI standard excludes “hazardous substances or adverse conditions such as environmental hazards, animal urine or feces, mold, fungus, allergens, toxins, carcinogens, asbestos, electromagnetic radiation, noise, radioactive substances, and contaminants in building materials, soil, water, and air.”1American Society of Home Inspectors. ASHI Standard of Practice for Home Inspections 2026

Testing for any of these requires a separately contracted service, often from a specialist with specific credentials. Lead-based paint inspection, for instance, requires EPA certification, or state certification in states that run their own programs.5U.S. Environmental Protection Agency. Lead-Based Paint Abatement and Evaluation Program – Individual Certification Radon testing, mold sampling, and termite inspections each carry their own licensing or certification requirements depending on the state.

Judgments and Determinations They Are Not Allowed to Make

Beyond physical limits, inspectors are not authorized to deliver certain conclusions. A home inspection is not an appraisal, a code compliance check, or a prediction.

Business Conduct They Are Prohibited From

The ASHI Code of Ethics draws a firm line around financial conflicts. Inspectors cannot accept compensation for recommending contractors, services, or products to their clients. They also cannot pay referral fees to real estate agents or other parties with a financial interest in the transaction in exchange for being recommended or placed on a “preferred providers” list.6American Society of Home Inspectors. ASHI Code of Ethics

A related rule surprises some inspectors. Under the ASHI standard, an inspector cannot repair, replace, or upgrade any system or component covered by the inspection standards for compensation within one year after performing the inspection.7American Society of Home Inspectors. ASHI Code of Ethics The reason is obvious: if inspectors could generate their own repair business, every report would suddenly find more problems. Many states have adopted similar prohibitions into their licensing laws.

If your inspector hands you a business card for a roofer or offers to come back and fix something they found, treat that as a warning sign. Their role is to identify and describe defects, then recommend further evaluation by a qualified professional when appropriate.

What the Report Does Not Guarantee

Even with everything an inspector does cover, the report is a snapshot of the property’s condition on the day of the walkthrough. It is not a warranty, an insurance policy, or a guarantee that everything works. Systems that functioned during the inspection can fail the next week, and hidden defects that were not visible or accessible will not appear in the report. Industry standards specifically prohibit inspectors from offering warranties or guarantees of any kind.4International Association of Certified Home Inspectors. InterNACHI Standards of Practice for Performing a General Home Inspection Latent defects concealed behind finished surfaces or underground are explicitly excluded.1American Society of Home Inspectors. ASHI Standard of Practice for Home Inspections 2026

The practical takeaway is to treat the general inspection as the foundation of your due diligence, not the whole of it. Clear access to every mechanical area before the appointment, confirm utilities are on, attend the inspection in person so you can ask questions in real time, and schedule specialized inspections for the systems and hazards the general inspection cannot touch.
