Home inspectors cannot perform repairs, move furniture, conduct invasive testing, or provide opinions on property value or building code compliance. These 10 home inspector limitations apply nationally under both InterNACHI and ASHI standards, and they define exactly what your home inspection report will and will not address.
The restrictions exist for two reasons: conflicts of interest and liability. An inspector who can also quote repairs has a financial incentive to find more problems. An inspector who moves a bookcase faces a property damage claim if it gets scratched. Both InterNACHI and ASHI home inspection standards codify these rules to protect inspectors, buyers, and sellers alike. State licensing laws sometimes add stricter requirements on top.
This guide covers the 10 specific things home inspectors cannot do, a side-by-side comparison of InterNACHI and ASHI home inspection standards, which specialized systems get excluded from a standard inspection, the biggest home inspection red flags by repair cost, how home inspection deal breakers affect a transaction, and what your options are when a serious finding puts a sale at risk.

What home inspectors are not allowed to do
A licensed home inspector operates within a defined scope set by the InterNACHI Standards of Practice or ASHI. These home inspector limitations are not arbitrary. Each one reflects a decision about liability, licensing scope, or conflicts of interest. Here are the 10 specific prohibitions every buyer and seller should know.
1. A home inspector cannot perform or refer repairs
An inspector cannot perform, offer to perform, or refer repair work on any system or component they inspected. InterNACHI’s Standards of Practice ban this explicitly to eliminate conflicts of interest. An inspector who profits from finding defects loses the impartiality the buyer is paying for.
2. A home inspector cannot conduct invasive testing
Standard home inspections are non-invasive inspections by definition. Inspectors cannot remove drywall, open walls, dismantle plumbing, or disassemble mechanical systems. If a defect requires invasive testing to confirm, the inspector notes the limitation in the home inspection report and recommends a licensed specialist.
3. A home inspector cannot move furniture or objects
Inspectors are not required to move personal items, furniture, floor coverings, appliances, or stored belongings. If an electrical panel is blocked by shelving, the inspector documents the obstruction and notes the area as inaccessible. Moving items creates direct liability for property damage.
4. A home inspector cannot inspect unsafe areas
Inspectors cannot enter areas that present a safety hazard to themselves. Per InterNACHI’s SOP, this includes crawlspaces with standing water and attic spaces with head clearance below 36 inches. Unsafe areas are noted in the home inspection report as uninspected, not skipped without explanation.
5. A home inspector cannot test for mold, radon, or asbestos
A mold inspection, a radon test, and asbestos testing each require separate licensing and specialized equipment. Standard inspectors cannot perform or interpret these tests. An inspector who sees suspicious staining will note it in the report but must refer you to a licensed specialist for follow-up.
6. A home inspector cannot estimate property value
Inspectors are prohibited from giving opinions on a property’s value, marketability, or insurability. Value determination belongs to a licensed appraiser; insurability belongs to an insurance agent. Speculating on either creates liability and falls outside the scope of any standard home inspection.
7. A home inspector cannot give a pass or fail verdict
There is no pass or fail inspection outcome in a home inspection. An inspector documents observable conditions in a written report and does not recommend for or against purchase. The buyer, seller, and their agents decide what the findings mean for the transaction.
8. A home inspector cannot determine building code compliance
Building codes vary by municipality, change over time, and require a licensed building official to interpret. Inspectors observe visible conditions but cannot determine whether a system meets current code or whether prior permits were pulled. Home inspection standards from both InterNACHI and ASHI exclude code compliance opinions from inspector scope.
9. A home inspector cannot identify property lines
Inspectors do not survey the property or identify legal boundaries. Questions about whether a fence, outbuilding, or addition crosses a property line require a licensed surveyor. The inspector’s scope covers physical systems and components inside and immediately around the structure.
10. A home inspector cannot inspect non-working systems
Inspectors test systems in their normal operating mode. If a furnace has no power, a dishwasher is disconnected, or a ceiling fan switch is removed, the inspector notes the item as non-operational and does not attempt to diagnose it. Testing non-working systems risks electrical damage, gas leaks, and personal injury.
InterNACHI vs. ASHI: key inspection limits compared
Both InterNACHI and ASHI set the national baseline for home inspection standards in the United States. They were developed independently, but both organizations converge on the same core prohibitions, reflecting broad liability consensus across the industry. The ASHI Standards of Practice Section 13.2 lists general limitations and exclusions explicitly. InterNACHI SOP Section 2.1 defines “readily accessible” as available without requiring moving of personal property, dismantling, destructive measures, or any action likely to involve risk to persons or property.
The table below maps eight home inspector limitations across both standards so you can see where the rules align and where language differs.
| Limitation Area | InterNACHI Standard | ASHI Standard |
|---|---|---|
| Moving furniture or personal items | Not required | Not required |
| Walking on the roof | Not required if unsafe | Not required if unsafe |
| Entering confined or unsafe spaces | Only if safe and accessible | Only if safe and accessible |
| Performing repairs on inspected items | Prohibited | Prohibited |
| Estimating remaining useful life of systems | Not required | Not required |
| Testing for mold, radon, or asbestos | Not required (refer to specialists) | Not required (refer to specialists) |
| Building code compliance opinions | Not required | Not required |
| Property value or insurability opinions | Not required | Not required |

How both standards handle inspector access
Both standards define access the same way: an area is accessible if the inspector can reach it without moving personal property, using destructive methods, or risking injury. If access requires any of those steps, the inspector is not required to attempt it. The home inspection report must note that the area was not inspected and explain why.
Where the two standards differ on safety exclusions
The standards are nearly identical on safety exclusions, but InterNACHI’s SOP provides more specific numeric thresholds, such as the 36-inch head clearance minimum for attic access. ASHI’s language is broader, referencing “safe and reasonable access” without specific measurements. In practice, both sets of home inspection standards lead to the same result: inspectors do not enter genuinely hazardous spaces.
Can home inspectors move furniture or belongings?
Home inspectors are not permitted to move furniture, appliances, rugs, or other personal items during an inspection, per both InterNACHI and ASHI Standards of Practice. This rule is one of the most frequently misunderstood home inspector limitations, particularly for buyers who learn that an electrical panel was partially blocked during their inspection.
The reason is liability. If a bookcase is scratched while being moved, the inspector faces the property damage claim. Because inspectors carry errors and omissions insurance rather than general liability coverage for personal property, the risk is significant enough that ASHI inspection guidance and InterNACHI both exclude moving personal property from inspection requirements.
What the standards say about personal property
Both InterNACHI and ASHI Standards of Practice explicitly exclude moving furniture, rugs, floor coverings, wall coverings, plants, and debris from inspector requirements. ASHI SOP Section 13.2.A.1 states that inspectors are not required to move personal items, furniture, floor coverings, or equipment. Any area that was inaccessible due to personal property is noted as such in the home inspection report, which can raise buyer concerns even when no defect exists behind the blocked area.
How sellers should prepare before the inspection
Sellers can prevent “inaccessible area” notations in the report by clearing access points before the inspector arrives. Follow these five steps before the inspection date:
- Clear at least 3 feet of space around the electrical panel.
- Move all stored items away from the water heater and HVAC unit.
- Ensure the attic access hatch is unobstructed and unlocked.
- Unlock all outbuildings, crawlspace hatches, and detached garages.
- Confirm all utilities are active, including gas, water, and electricity.
Sellers who handle these steps eliminate the “could not access” language that buyers often interpret as a red flag, regardless of what is actually behind the door.
What specialized systems do home inspectors skip?
A standard home inspection covers the visible, accessible systems inside and immediately around the main structure. It does not cover every system on the property, and buyers who assume otherwise sometimes skip a specialized inspection and discover a costly problem only after closing.
Systems excluded from a standard home inspection
Per InterNACHI’s scope, the following are excluded from a standard inspection:
- Underground storage tanks
- Swimming pools and spas
- Septic systems
- Private water wells
- Detached structures other than carports and attached garages
- Solar panels
- Elevators
- Low-voltage wiring systems
- Security systems
- Water softeners
- Fire suppression systems
These exclusions are not gaps in inspector competence. They require specialized inspection equipment, separate licensing, or a scope of work distinct from a non-invasive inspection of residential structure and systems.
When to order a separate specialist inspection
If the property includes any excluded system listed above, ordering a separate specialized inspection before closing is standard practice. Cost ranges for common add-ons:
- Sewer scope (lateral line camera): $100 to $300. The sewer line inspection cost is among the most common add-ons buyers request, because a failed sewer lateral is invisible during a standard inspection and can cost $3,000 to $25,000 to replace.
- Well inspection: $150 to $500 depending on tests ordered. Standard inspectors do not evaluate private wells; well inspection pricing covers what a separate test includes.
- Radon test: $15 to $30 for a DIY kit or $90 to $250 professional. Per EPA radon testing guidance, the EPA action level is 4 pCi/L.
- Mold inspection: $300 to $1,000 depending on scope.
- Asbestos testing: $200 to $800 for a limited survey.
- Wood-destroying organism (termite) inspection: $50 to $150; often required separately by lenders.
Biggest red flags in a home inspection
Home inspection red flags are findings that signal high repair costs, ongoing safety hazards, or conditions that could affect financing. Not every finding in an inspection report qualifies. Missing GFCI outlets, an aging water heater, or minor caulking gaps are common findings that rarely threaten a transaction. The categories below are different in scale and consequence.
Structural and foundation problems
Foundation problems top the list of home inspection red flags across every major source. Horizontal cracks in block or poured basement walls signal lateral soil pressure and potential structural failure. Uneven floors, sticking doors, and out-of-square window frames are secondary indicators of foundation movement.
Foundation repair costs range from $3,000 to $75,000 or more depending on method (slab jacking, pier installation, or full underpinning). These structural issues are generally not covered by standard homeowners insurance policies, and they can disqualify a home from FHA or VA financing.
Water damage and moisture intrusion
Water staining on ceilings, buckling floors, efflorescence (white mineral deposits) on basement walls, and musty odors are the primary signals of moisture intrusion. Active leaks, past flood damage, and chronic condensation all fall into this category.
Per CDC mold health guidance, mold exposure carries documented health risks. Mold remediation costs $500 to $30,000 or more depending on the affected area. Inspectors can note visible moisture staining, but a full mold inspection requires a licensed specialist. Fireplace and chimney defects often appear in the same section of a home inspection report as moisture findings; the fireplace inspection findings article covers how those conditions affect value and buyer negotiations.
Electrical and HVAC system failures
Three electrical configurations consistently appear as serious home inspection red flags: knob-and-tube wiring (pre-1940s), aluminum branch circuit wiring (1960s to 1970s), and Federal Pacific Stab-Lok panels. Each is a documented fire hazard. Rewiring costs range from $8,000 to $30,000 depending on the home’s size and accessibility.
HVAC systems older than 15 to 20 years are past typical manufacturer-rated useful life. A system that fails to heat or cool during the inspection is not just a comfort issue. Many lenders require operational heating and cooling before a loan closes. Replacement costs run $5,000 to $12,000.
What’s the worst thing a home inspector can find?
The five costliest inspection discoveries are ranked here by repair cost and transaction impact.
The five costliest inspection discoveries
-
Structural or foundation failure ($3,000 to $75,000+). This is the worst single finding an inspector can report. Repair costs are high, standard homeowners insurance does not cover foundation failure, and the home may be ineligible for FHA or VA financing per HUD property standards for financed properties.
-
Severe water intrusion or active mold ($500 to $30,000+). Active leaks combined with mold growth require remediation before most lenders will close. The health implications documented by the CDC and the structural implications of prolonged moisture make this a frequent deal-ender in financed transactions.
-
Faulty or dangerous electrical ($8,000 to $30,000). Knob-and-tube wiring, aluminum branch circuit wiring, and Federal Pacific panels each create fire and shock hazards. Many insurers refuse to write policies on homes with these systems, which can make a property effectively unfinanceable regardless of the buyer’s loan program.
-
Failing or absent HVAC ($5,000 to $12,000). Lenders may require operational heating before closing on a financed purchase. An HVAC system that does not function on the day of inspection creates a lender-required repair condition in many loan programs.
-
Pest infestation with structural damage ($3,000 to $20,000+). Termite damage to load-bearing framing combines high repair cost with the kind of structural issues that trigger property condition disclosure requirements in most states.
Issues that can make a home unfinanceable
FHA and VA loans have minimum property standards that go beyond cosmetic condition. Per HUD handbook 4000.1, the following conditions can prevent loan approval until remediated:
- Active roof leaks
- Foundation or structural defects
- Inoperable heating systems
- Exposed or hazardous electrical wiring
- Evidence of significant pest damage to load-bearing structure
Conventional loans have less stringent requirements, but lenders retain discretion. A home inspection report that identifies any of these conditions in a financed transaction will likely trigger a repair requirement or a lender-mandated re-inspection before closing.
What counts as a deal breaker in a home inspection?
Home inspection deal breakers are findings serious enough in cost, safety risk, or lender implications to cause a buyer to renegotiate or exit a contract. Not every problem in a home inspection report reaches that threshold. A cracked driveway does not. A failed foundation does.
Repair request vs. deal breaker: the distinction
Minor and moderate findings typically become repair requests or closing credits. A buyer might ask the seller to fix a leaking faucet, replace missing GFCI outlets, or credit the cost of a new water heater at closing. Home inspection deal breakers are different in kind: they involve costs or risks large enough that the buyer’s lender may reject the loan, the buyer’s insurer may refuse coverage, or the buyer’s financial exposure exceeds what a credit can fairly offset.
Issues lenders require fixed before closing
Some findings are lender-required repairs, not buyer preferences. FHA and VA loans require the property to meet HUD minimum property standards at closing. Conventional lenders have more flexibility, but appraisers must flag conditions that affect habitability or safety. Findings in the table below regularly trigger a lender condition on financed purchases.
| Deal-Breaker Issue | Typical Repair Cost | Typical Outcome |
|---|---|---|
| Foundation failure | $10,000 to $75,000+ | Walk or major price reduction |
| Major roof damage (active leak) | $5,000 to $15,000 | Negotiate or lender requirement |
| Outdated/dangerous electrical | $8,000 to $30,000 | Lender may require fix before closing |
| Sewer line failure | $3,000 to $25,000 | Negotiate repair credit |
| Active water intrusion or mold | $500 to $30,000+ | Walk or require remediation |
| Pest structural damage (termites) | $3,000 to $20,000 | Negotiate |
| Asbestos or lead paint (active risk) | $1,000 to $30,000 | Disclose and negotiate |
| Failing HVAC (no heat or cooling) | $5,000 to $12,000 | Negotiate or lender requirement |
| Septic system failure | $3,000 to $20,000 | Negotiate |
| Radon above 4 pCi/L | $800 to $2,500 | Mitigation negotiation |
Repair cost ranges are current estimates for 2026. Verify current contractor pricing before using these figures in negotiations.
For sewer-related issues specifically, the sewer scope inspection guide covers what a camera scope reveals and how to evaluate competing repair bids.
When to walk away vs. negotiate a credit
Foundation failure and severe structural issues are the hardest home inspection deal breakers to negotiate around. Foundation problems are generally not covered by standard homeowners insurance policies, which means the buyer absorbs the full repair cost after closing. A credit at closing often underestimates the actual scope of work needed. For all other deal-breaker findings, a credit or price reduction tied to current contractor bids is a standard resolution that can keep both parties in the deal.
What these findings mean for your home sale
A home inspection report with serious findings puts pressure on a financed transaction in two ways: the buyer’s lender may require repairs before closing, and the buyer can invoke an inspection contingency to exit the contract without penalty. Understanding your options gives you control over what happens next.
Three options sellers have after a difficult inspection
-
Make repairs before closing. Sellers who fix identified issues can often keep the original buyer and sale price intact. The risk is time and cost overruns. Completion before the closing date is not always guaranteed, especially for structural repairs.
-
Offer a price reduction or credit. The buyer accepts the property in its current condition in exchange for a credit at closing equal to the estimated repair cost. This is the most common resolution for moderate findings and avoids the scheduling pressure of pre-closing repairs.
-
Sell as-is. The seller includes a property condition disclosure covering the inspection findings and adjusts the asking price accordingly. Financed buyers may still face lender conditions, but cash buyers who factor the property’s condition into the offer price are not subject to lender-required repair mandates.
Why cash offers behave differently after an inspection
Financed buyers can use an inspection contingency to renegotiate or exit a contract without penalty, returning the seller to the start of the process after weeks of waiting. Cash buyers typically waive or limit inspection contingencies because they are not subject to lender minimum property standards. Sellers who want to evaluate all available options after a difficult inspection will find a useful starting point in the best real estate websites guide for comparing sale paths and buyer types.

Frequently Asked Questions
Home inspectors are not allowed to perform repairs, conduct invasive testing, move personal belongings, or give opinions on property value or building code compliance. These 10 prohibitions apply to all licensed inspectors operating under InterNACHI or ASHI Standards of Practice. Most restrictions exist to prevent conflicts of interest or limit liability for property damage.
Home inspectors are not permitted to move furniture, appliances, rugs, or other personal items, per both InterNACHI and ASHI Standards of Practice. Both standards explicitly exclude moving personal property from inspection requirements. The rule protects inspectors from liability if an item is damaged during the move.
No, home inspectors are prohibited from performing or offering to perform repairs on any system or component they inspected. InterNACHI’s Standards of Practice ban this explicitly to eliminate conflicts of interest. An inspector who profits from finding defects cannot provide an impartial home inspection report.
Home inspectors are not required to walk on a roof if doing so would be unsafe, and many do not. Both InterNACHI and ASHI standards limit roof inspection to areas that are safely and readily accessible. Inspectors typically observe the roof from the ground or from a ladder at the eave rather than climbing onto a steep or wet surface.
Home inspectors are not authorized to test for mold, conduct a radon test, or perform asbestos testing as part of a standard home inspection. Each test requires a licensed specialist and separate equipment. Radon testing costs $15 to $250 depending on method; mold inspection costs $300 to $1,000; asbestos testing starts around $200 to $800.
The biggest home inspection red flag is a foundation or structural problem, with repairs costing $10,000 to $75,000 or more. Horizontal cracks in basement walls, uneven floors, and sticking doors all indicate foundation movement. These structural issues are generally not covered by standard homeowners insurance and can disqualify a home from FHA or VA financing.
The worst finding in a home inspection is a compromised foundation or major structural failure, which can cost tens of thousands to repair. Severe mold, dangerous electrical wiring such as knob-and-tube or Federal Pacific panels, and active roof leaks rank closely behind. Any of these can trigger lender-required repairs, a renegotiation, or a buyer invoking their inspection contingency to exit.
A deal breaker in a home inspection is a defect serious enough in cost, safety, or lender implications to cause a buyer to exit the contract. Foundation failure, major roof damage, dangerous electrical, and active mold are the most common home inspection deal breakers. Foundation problems are especially difficult to negotiate because standard homeowners insurance does not cover them.
Home inspectors cannot issue a pass or fail inspection verdict on a home. A home inspection report documents observable conditions and does not grade the property or recommend for or against purchase. The buyer and their agent use the report to decide whether to proceed, negotiate, or walk away.
No, home inspectors are prohibited from giving opinions on a home’s value, marketability, or insurability under standard home inspection standards. Value opinions belong to a licensed appraiser, and insurability assessments belong to an insurance agent. An inspector who speculates on value creates professional liability and risks misleading the buyer.
If a home inspector misses a visible, accessible defect, the buyer may have a legal claim against the inspector’s errors and omissions insurance. Inspectors cannot be held liable for defects hidden behind walls or in areas they were not required to access. State licensing boards regulate inspector liability, and requirements vary significantly by state.
Home inspectors check all accessible living spaces but are not required to enter rooms or areas that are locked, blocked by personal property, or unsafe to access. If a room is locked or a crawlspace has standing water, the inspector notes the area as uninspected rather than forcing access. Sellers should ensure all areas are unlocked and clear before the inspection date.
Home inspection licensing requirements and prohibited practices vary by state, not just by professional standards. California home inspection law explicitly restricts inspectors from performing engineering analysis or determining code compliance. Some states have no licensing requirement at all, while InterNACHI and ASHI Standards of Practice provide the national baseline where state law does not conflict.
Sellers should prepare by clearing access around utilities, unlocking all outbuildings, and ensuring all systems are active before the inspection date. Specifically: clear 3 feet around the electrical panel, move items away from the HVAC unit and water heater, confirm the attic hatch is unobstructed, and replace any burned-out bulbs. These steps prevent “could not access” notations in the home inspection report that buyers often read as a red flag even when no underlying defect exists.
