What Will Fail a House Inspection?
What the Question Really Means
Home inspections do not pass or fail. There is no score, no grade, and no outcome where an inspector declares a house uninhabitable or blocks a sale. What an inspection produces is a report: a documented description of the condition of the home at the time of the inspection. What buyers and sellers do with that information is a separate matter entirely.
That said, the question “what will fail a house inspection” is really asking something useful: what kinds of findings are serious enough to matter, and are there findings that could affect a lender’s willingness to finance the home? Both of those are worth understanding. This article addresses them directly.
What you need to know before reading further
- Home inspections do not pass or fail. They produce a report describing the condition of the home.
- There is no finding that automatically stops a sale. The inspection is informational, not transactional.
- Lenders are a separate consideration. FHA, VA, and some conventional loans require certain conditions be met before funds are released, and appraisers flag those issues independently.
- The findings that matter most are those involving safety, structure, active water damage, and major system failures.
- Most findings are repairable. A long list of items on a report is normal for older homes and does not mean the home is a problem property.
First: Inspections Do Not Pass or Fail Homes
The Myth
An inspector grades the home, and if it scores poorly or has certain defects, it “fails” and the sale cannot proceed.
The Reality
An inspector documents what they observe. The report describes conditions. Nothing in a home inspection report stops a sale or requires a seller to make repairs. The inspection is for the buyer’s information.
A home inspector’s job is to report on the condition of the property as it exists on the day of the inspection. A cracked foundation wall, a failing roof, active water intrusion in the crawlspace: all of these will be documented clearly when observed. None of them constitute a “fail.” The buyer receives that information and proceeds from there with their agent, their lender, and whatever other professionals they choose to consult.
Oregon and Washington home inspectors are licensed professionals operating under state Standards of Practice. Those standards define what inspectors must report on, but they do not give inspectors authority over whether a transaction proceeds. That authority belongs to the buyer, the seller, and in some cases the lender.
Where the “Fail” Idea Actually Comes From
The confusion usually traces to two sources: lender requirements and the inspection contingency.
If you are financing a home purchase with an FHA loan, a VA loan, or certain conventional loan products, the lender’s appraiser will evaluate the property against a separate set of minimum property standards. Those standards exist to protect the lender’s collateral, and they do look something like a pass/fail checklist. If an appraiser flags a condition that does not meet those standards, the lender may require it to be repaired before closing the loan. That is a lender requirement, not an inspection finding, but in practice it often comes up during the same transaction.
The inspection contingency is the other source of confusion. Many purchase agreements in Oregon and Washington include a clause that gives the buyer a defined window to have the home inspected and, if findings are unsatisfactory, to walk away from the transaction. The contingency gives the buyer an exit option based on inspection findings. It does not mean the inspection “failed.” It means the buyer reviewed the information and chose not to proceed.
What Lenders Actually Flag
FHA and VA Loan Minimum Property Standards
FHA and VA loans have the most specific property condition requirements. Appraisers for these loan types are trained to flag conditions that affect the safety, soundness, or security of the home. Common examples include roofs with less than two years of remaining life, exposed wiring or open electrical panels, missing handrails where the appraiser sees a safety hazard, broken windows, inoperable heating systems, active water intrusion visible at the time of the appraisal, peeling paint in homes built before 1978 (a lead paint concern), and evidence of significant structural damage.
These are the items that can genuinely delay or complicate financing, and they are worth understanding separately from the broader inspection findings. Your lender and their appraiser are the authoritative source on what their specific loan product requires. The home inspector documents conditions; the appraiser determines whether those conditions meet the lender’s standards.
The Findings That Matter Most
Even though no finding technically “fails” a home inspection, some findings carry significantly more weight than others. The categories below represent the types of conditions that buyers, sellers, and their agents pay closest attention to in the Portland metro and SW Washington area.
Structural and Foundation Issues
High significance
Active or progressive foundation movement, horizontal cracks in basement or crawlspace walls, significant floor sloping, and framing damage from water or pest activity all fall into this category. These findings matter because they affect the physical integrity of the home and can be expensive to address. Most are repairable, but the scope and cost of repair varies widely. Minor settling and hairline cracks are normal in older homes and do not rise to this level. The concern is with movement that appears progressive or damage that has compromised load-bearing components.
Roof Condition
High significance
A roof with very little remaining life, active leaking, or significant structural issues at the decking or framing level is one of the most commonly noted major findings. Roofing is expensive to replace, typically $10,000 to $25,000 or more in the Portland area depending on size and materials, and a failing roof allows water into the home which compounds other problems. Inspectors document the approximate age of the roofing material, the condition of flashing and penetrations, and any visible evidence of active leaking. FHA appraisers are required to report a roof that does not have at least two years of remaining physical life.
Electrical Safety Hazards
High significance
Exposed wiring, open junction boxes, Federal Pacific Stab-Lok panels, Zinsco panels, double-tapped breakers on circuits not rated for it, missing GFCI protection in wet areas, and unpermitted DIY electrical work all appear regularly in inspections on older Portland-area and SW Washington homes. Electrical defects that represent a genuine fire or shock risk are the most significant in this category. Many electrical findings are moderate code updates rather than immediate hazards, but the two can look similar on paper. A good inspector will distinguish between them clearly in the report.
Plumbing Problems
Moderate to high significance
Active leaks at supply or drain lines, failing water heaters past their service life, polybutylene pipe (a material with a documented history of failures used in many Portland-area homes built from the late 1970s through the mid-1990s), and galvanized steel supply pipes that have significantly reduced interior diameter from corrosion are the plumbing findings that carry the most weight. A water heater that is 15 years old is a common, budgetable expense. Polybutylene pipe throughout the home is a more complex situation that typically involves a specialist evaluation.
Sewer lines are a separate question. The underground sewer lateral is not part of a standard home inspection, because the pipe is buried and cannot be seen. Older Portland neighborhoods often have clay tile laterals, which can crack, separate at the joints, or let roots in over time. A sewer scope arranged separately through a plumber is how buyers see the inside of that line, and it is recommended on every home.
Active Water Intrusion
High significance
Water that is actively entering the home through the foundation, walls, or roof is one of the most significant findings in any inspection, particularly in the wet Pacific Northwest climate. The concern is not just the current condition but the ongoing damage water causes over time: framing rot, mold growth, insulation deterioration, and compromised structural components. Inspectors look for the source of intrusion, not just the symptoms. A wet crawlspace with standing water and soft framing tells a very different story than a single ceiling stain from a roof leak that was repaired two years ago. Thermal imaging, included at no additional charge on every inspection, is particularly useful here because it can show temperature patterns that may point to moisture in walls and ceilings with no visible surface evidence.
HVAC System Condition
Moderate to high significance
A heating system that does not operate, has a cracked heat exchanger, or is well past its expected service life is a finding that lenders and buyers pay attention to. In Oregon and Washington, an inoperable heating system can be flagged by FHA and VA appraisers as a minimum property standard issue. Furnaces typically last 15 to 20 years. A 25-year-old furnace that is still running is not automatically a problem, but its age and condition are documented because a replacement may be a near-term expense. Air conditioning is less of a lender concern in the Pacific Northwest but is increasingly relevant as the region experiences more extreme summer heat.
Real Inspection Photos
Findings That Carry the Most Weight
Real photos from Russ's inspection reports. None of these "fail" a home, but each gets a clear write-up.
-
This roof showed granule loss, curling, and general wear consistent with the end of its service life. Replacement is a large, budgetable cost. -
An open junction box with no cover can let sparks or heat from a bad connection reach nearby framing and insulation. -
Signs of active moisture seepage along a crawlspace wall. Water entering over time can affect framing, insulation, and air quality.
What Does NOT Make a Home “Fail”
It is worth being equally clear about what does not rise to the level of a serious finding, because inspection reports on older homes are long and can look alarming to first-time buyers who are not sure how to read them.
- Minor code updates. Homes are not required to be brought up to current building code simply because they were built to an older standard. A home built in 1965 without AFCI breakers is not a failed home. It is a home built under 1965 code. Many items inspectors flag as “recommended improvements” fall into this category.
- Cosmetic issues. Worn flooring, dated fixtures, surface cracks in drywall, and similar items appear in inspection reports but carry no structural or safety significance. Peeling paint is the exception in homes built before 1978, where it can be a lead paint concern rather than a cosmetic one.
- Normal wear on aging systems. A 12-year-old water heater that is functioning correctly will be noted in the report because its service life is limited, but it is not a defect. Inspectors document the age and condition of systems so buyers understand the maintenance timeline ahead of them.
- Deferred maintenance. A home that needs caulking at the tub surround, a new garbage disposal, and re-sealing on the driveway has deferred maintenance. That is different from a home with structural damage or safety hazards.
- Long reports. A 60-item report on a 1970s Portland-area home is not a problem home. It is a thorough inspector documenting everything they observed. The length of the report matters far less than the nature of what is in it.
Portland Metro and SW Washington: Regional Findings Worth Knowing
Homes in this area have a specific set of common findings that buyers encounter regularly. None of them automatically “fail” a home, but all of them are worth understanding before you get to the inspection report.
- Federal Pacific Stab-Lok and Zinsco electrical panels. These panels are found in a large number of pre-1980 homes throughout the Portland metro and SW Washington. Both have documented histories of breaker failure and are consistently flagged in inspection reports. They are repairable by replacing the panel, which typically costs $2,000 to $5,000. FHA and VA appraisers may flag them if there is visible evidence of arcing or damage.
- Polybutylene plumbing. Common in homes built from roughly 1978 through 1995 in this area. Poly pipe has a history of fitting failures that can cause significant water damage without warning. Inspectors document it when present. Full repiping typically runs $5,000 to $15,000 depending on home size and access.
- Attic moisture and mold. The combination of the Pacific Northwest’s wet climate and older homes’ ventilation and air-sealing deficiencies means attic moisture is one of the most common findings on pre-1990 homes in this area. The severity ranges from minor condensation staining to active mold growth requiring remediation.
- Crawlspace moisture and framing damage. Most Portland-area and SW Washington homes have crawlspaces that collect moisture. Extended moisture exposure causes wood rot in the floor framing. Inspectors probe framing and document any areas with soft or deteriorated wood.
- Underground oil tanks. Properties that used oil heat before the natural gas conversion may have abandoned tanks underground. These are not always disclosed and are not visible during a standard home inspection. If there is evidence of past oil heat use, a separate tank sweep is worth considering. See the FAQ for more on what inspectors can and cannot evaluate.
The Honest Answer
Nothing will “fail” a house inspection in the way the question implies. What happens instead is that an inspector documents the visible condition of the home, and the buyer uses that information to better understand what they are buying. The findings that carry the most practical weight are those involving safety hazards, structural integrity, major water damage, and system failures that affect habitability. Those are the things worth paying attention to. Everything else is context.
