What Home Inspectors Actually Look For

What a Home Inspector Actually Evaluates

A licensed home inspector conducts a systematic, visual review of a home's accessible components — meaning anything they can see, touch, or safely test without opening walls or excavating the yard. The typical inspection covers seven major areas:

• Roof and attic: Shingles, flashing, gutters, ventilation, and signs of water intrusion or structural sagging.
• Foundation and structure: Visible cracks, settling, moisture in the basement or crawl space, and the overall integrity of load-bearing elements.
• Electrical system: The main panel, wiring types, grounding, GFCI outlets in wet areas, and any visible code concerns.
• Plumbing: Water pressure, drainage, supply lines, water heater condition and age, and signs of leaks or corrosion.
• HVAC systems: Heating and cooling equipment, filters, ductwork, age of units, and functional operation.
• Interior surfaces: Walls, ceilings, floors, windows, and doors — checked for water staining, cracks, and operational issues.
• Exterior: Siding, grading (whether the ground slopes away from the foundation), driveways, decks, and attached structures.

Inspectors follow standards of practice set by professional bodies and document findings with photos and written descriptions. The result is a detailed report — often 30 to 60 pages — that becomes a critical reference for buyers.

What Falls Outside the Scope

Just as important as what inspectors cover is what they don't cover. Standard inspections are non-invasive and visual. They cannot detect issues hidden inside walls, beneath flooring, or underground. Common exclusions include:

• Mold and air quality testing — requires a certified industrial hygienist or environmental consultant.
• Pest and termite inspections — a separate licensed pest inspector is needed, and some lenders require this for certain loan types.
• Radon and asbestos — both require specialized testing by qualified professionals.
• Septic systems and private wells — typically require their own inspection and water testing.
• Chimney interiors — a chimney sweep or certified chimney inspector provides more thorough evaluation.

If an inspector notices signs that suggest any of these concerns — such as discoloration that could indicate mold, or wood damage consistent with termite activity — they will flag it and recommend a specialist. Think of the general inspection as a starting point, not a complete diagnostic.

How to Use the Report Strategically

Receiving an inspection report filled with dozens of items can feel alarming, but context matters enormously. Inspectors are thorough by design — they note even minor maintenance items alongside genuinely significant concerns. The key is distinguishing between the two categories.

Items that warrant serious attention typically involve safety hazards (exposed wiring, missing smoke detectors), major systems nearing the end of their useful life, or evidence of water intrusion affecting structural elements. These often justify requesting repairs or a credit from the seller.

Items that are routine maintenance — a worn caulk seal around a tub, a sticking window, or an aging but functional water heater — are part of normal homeownership. They are worth knowing about but rarely grounds for renegotiation on their own.

Buyers who understand the local market context interpret reports more effectively. See our guide to reading a real estate market report for broader context on how market conditions can influence negotiating leverage after an inspection.

If the report reveals deferred maintenance or items requiring licensed work, research what's involved before planning repairs.
