Short answer
A home inspection report is not a pass/fail document. It is a detailed record of what a licensed inspector observed during a visual examination — and it requires interpretation, not just reading. First-time buyers often either dismiss the report because "every house has issues" or feel overwhelmed by a 40-page document full of itemized observations. Neither response is helpful. The real question is: which findings warrant immediate follow-up, which require specialist evaluation, and which are routine maintenance items? This article gives first-time buyers a framework for working through an inspection report in Greater Seattle.
What a home inspection covers — and what it doesn't
Washington State requires home inspectors to be licensed under Chapter 18.280 RCW. Licensed inspectors must perform a visual, non-invasive examination of the following systems and components, as defined in RCW 18.280.030 and detailed in Chapter 308-408C WAC (the Washington State Standards of Practice for home inspectors): roof, foundation, exterior, heating system, cooling system, structure, plumbing, and electrical systems.
Most inspection reports also cover the attic and insulation, crawl space, fireplace, and interior doors and windows — consistent with the InterNACHI Standards of Practice that many Washington inspectors follow.
What a standard home inspection does not include:
- Sewer scope. The underground sewer lateral from the house to the street main is not part of a standard home inspection. A separate sewer scope — ordered from a sewer inspection company — is required to assess that system. In Greater Seattle, where older neighborhoods have cast-iron and clay sewer laterals, a sewer scope is a separate, commonly-needed evaluation.
- Specialist systems. Chimneys, oil tanks, mold testing, environmental hazards (lead, asbestos), and permitted addition verification each require a specialist or separate process.
- Inaccessible areas. Inspectors examine what is visually accessible. Finished walls, attic sections that cannot be safely entered, and buried components are outside the scope of a visual inspection.
How inspection reports are structured
Most reports have two parts: a summary page at the front listing items the inspector flagged as requiring action or further evaluation, and a longer full report with photographs and detailed observations for each system.
Buyers should read both — not just the summary. The full report contains context that the summary compresses. A finding listed as "monitor" in the summary may be more significant in the full description.
Inspectors generally categorize findings by severity (safety hazard, major defect, minor defect, maintenance item, or informational) or use a similar tiered system. The inspector's terminology varies, so ask your inspector to walk through the summary with you, or at minimum ask them to tell you what they would fix first if they owned the house.
Findings that warrant immediate follow-up
These categories of findings, if present, should be reviewed carefully and often require specialist evaluation before the inspection contingency expires.
Structural and foundation. Horizontal or stair-step cracks in foundation walls, bowing or leaning walls, significant differential settlement (where different parts of the structure have shifted at different rates), and visible framing issues are findings that warrant a structural engineer's review — not just a handyman's estimate. Inspectors can identify that something looks wrong; a structural engineer can tell you what it means and what it would cost to address.
Water intrusion and moisture. Staining, efflorescence (white mineral deposits on concrete or masonry), active moisture in the crawl space or basement, and evidence of past water in finished areas are high-priority findings. Water-related damage often extends beyond what is visible. An inspector who notes moisture should prompt the buyer to consider what is behind or beneath the affected area, not just whether the staining looks old. In Greater Seattle's wet climate, crawl space and drainage conditions are particularly relevant.
Electrical. Specific electrical panels have documented histories of safety concerns and have been the subject of class-action litigation: Federal Pacific Electric (Stab-Lok) panels and Zinsco panels are examples inspectors flag in older homes. These findings typically require evaluation by a licensed electrician. Other electrical red flags include aluminum branch wiring (common in homes built in the 1960s–70s, which requires special outlets and devices when present), double-tapped breakers (two wires connected to a single breaker not designed for it), and ungrounded outlets in areas that require grounding by current code.
Roof at or near end of useful life. Inspectors do not guarantee roof life, but they can observe visible wear, granule loss on asphalt shingles, cracked or missing shingles, and the condition of flashing at chimneys and valleys. A roof identified as "near end of useful life" or "recommend further evaluation" by a roofer is a material cost consideration: verify the age of the roof and ask for a roofing contractor estimate before your inspection contingency expires.
Deferred HVAC maintenance. An inspector can confirm that heating and cooling systems are functioning at the time of inspection but cannot fully evaluate heat exchanger condition, internal components, or efficiency. Age matters: a furnace at or beyond the typical end of its service life with no maintenance records represents an unknown replacement timeline. Ask for maintenance records and confirm with an HVAC specialist if the inspector notes concerns.
Findings that are common and contextual
Not every finding in a report requires specialist review or renegotiation. Inspectors in Greater Seattle commonly note:
- Gutters and drainage grading. Improper grading (ground sloping toward the foundation) and overflowing or damaged gutters are common and often correctable, but they matter in Seattle's rainfall climate because they affect whether water is directed toward or away from the structure.
- Deck or exterior wood maintenance. Older decks, trim, and fence boards showing weathering are routine maintenance items unless the inspector identifies active rot or structural concerns.
- Minor plumbing items. Dripping faucets, slow drains, and older fixtures are routine maintenance. A water heater at or past its expected service life is a replacement-planning item, not necessarily urgent, unless the inspector notes signs of failure or corrosion.
"Recommend further evaluation" — what that phrase means
When an inspector writes "recommend further evaluation by a qualified professional," that is not a soft suggestion. It means the inspector observed something that is outside what a visual examination can fully assess, and they are recommending a specialist look at it. In Washington, inspectors are trained not to overstate or diagnose — the WAC standards define the scope of a visual inspection. "Further evaluation" is how inspectors communicate that the finding warrants more than they can determine non-invasively.
Buyers should treat each "further evaluation" recommendation as a line item: who is the right specialist, how long will it take to get them scheduled within the inspection period, and what is the cost and scope of the follow-up?
The inspection period is your primary window
Washington is a buyer-beware state. Buyers generally do not have post-closing recourse against a seller for property conditions unless the seller made material misrepresentations. The inspection period — and any pre-inspection done before an offer — is the buyer's primary opportunity to develop a clear picture of the property's condition before removing the inspection contingency. Findings that feel minor during the excitement of going under contract can become significant costs after closing.
Ask the inspector at the end of the walkthrough: "If you owned this house, what would be the first things you'd address?" That question often produces more useful prioritization than the summary page alone.
Questions to ask before your inspection contingency expires
- What does the inspector classify as a safety concern vs. a major defect vs. routine maintenance?
- Which "further evaluation" recommendations are most urgent to schedule within the contingency period?
- Was a sewer scope ordered separately, and if not, should it be given the home's age and sewer lateral condition?
- Has the inspector seen evidence of unpermitted work? (Finished basement with no permit, HVAC modifications, electrical work that doesn't match the panel schedule.)
- Are there any findings the inspector thinks the seller may already be aware of based on how the condition presents?
