Home Inspection Checklist for Buyers: What to Expect in 2026
A home inspection is one of the most valuable investments you'll make in the homebuying process. For an average cost of $350–$500, a qualified home inspector can reveal major issues — structural problems, failing systems, water damage, safety hazards — that could cost you tens of thousands of dollars if left undiscovered. Buyers who use inspection findings to negotiate save an average of $14,000 off the final sale price, making the inspection one of the highest-return steps in the entire process.
What Is a Home Inspection?
A home inspection is a visual assessment of a home's condition conducted by a licensed professional inspector. It is not a pass/fail test — it's a comprehensive report on the current condition of the property, covering all major systems and structural components.
The inspection is typically ordered and paid for by the buyer during the due diligence or inspection contingency period — usually 7–14 days after the purchase contract is signed. The average cost is about $343–$500, depending on home size and location.
How Long Does a Home Inspection Take?
For an average-sized single-family home (1,500–2,500 square feet), a thorough home inspection typically takes 2–4 hours. Larger homes, older homes, or homes with complex systems take longer. Inspectors typically deliver a written report within 24–48 hours of the inspection.
Should You Attend the Inspection?
Yes — always attend if possible. Walking through with the inspector in real time gives you context a written report alone can't provide. You'll see issues firsthand, ask questions in the moment, understand which findings are minor vs. significant, and learn about the home's systems (water shutoff location, HVAC configuration, etc.).
What Does a Home Inspector Look For?
Exterior
- Foundation – Visible cracks, settling, soil grading away from the home
- Exterior walls – Siding condition, signs of rot, damage, or pest activity; caulking around windows and doors
- Roof – Age and condition of shingles; flashing around chimneys, skylights, and vents; gutters and downspouts
- Driveway and walkways – Cracks, settlement, or drainage issues
- Decks, porches, and balconies – Structural integrity, railing stability, signs of rot
- Garage – Door operation (auto-reverse safety), structural condition, fire separation from living space
Structural Components
- Foundation – Cracks, bowing walls, evidence of water intrusion, previous repairs
- Framing – Visible framing in attic and crawlspace; signs of damage, improper modifications, or pest damage
- Attic – Insulation levels, ventilation, evidence of leaks or moisture, signs of pest activity
- Crawlspace (where applicable) – Moisture, standing water, vapor barrier condition, structural integrity
Plumbing
- Water supply lines – Material (copper, PEX, galvanized steel, polybutylene); age and condition; visible leaks
- Drain, waste, and vent lines – Visible blockages or slow drains
- Water heater – Age, capacity, type, condition, TPR valve
- Main water shutoff – Location and operation
- Water pressure – Tested at fixtures; normal range is 40–80 PSI
- All fixtures – Faucets, toilets, showers/tubs; operation, leaks, caulking condition
- Sump pump (if present) – Operation, discharge location, backup power
Electrical
- Main service panel – Amperage capacity, condition, signs of overheating; double-tapped breakers; proper labeling
- Wiring type – Copper vs. aluminum; presence of knob-and-tube or other older wiring types
- Outlets and switches – Function; GFCI outlets in all required locations (bathrooms, kitchen, garage, exterior)
- AFCI protection – Arc fault circuit interrupter breakers in sleeping and living areas
- Grounding and bonding – Proper grounding of the electrical system
- Smoke and CO detectors – Presence and function
HVAC (Heating, Ventilation & Air Conditioning)
- Heating system – Age, type, condition, filter condition, recent service history
- Cooling system – Age, type, condition, refrigerant status
- Ductwork – Visible condition, sealing, insulation
- Thermostat – Operation and function
- Estimated remaining useful life – HVAC systems typically last 15–20 years
- Combustion safety – For gas furnaces and boilers, inspectors check for CO risks and proper venting
Interior
- Walls and ceilings – Cracks, stains, signs of water intrusion or past leaks
- Floors – Condition, soft spots, squeaks, signs of water damage or settling
- Windows – Operation, fogged double-pane glass (failed seal), latches and locks
- Doors – Operation, weatherstripping, locks
- Stairs and handrails – Stability, code compliance
- Fireplaces and chimneys – Damper operation, visible liner condition, flashing
What a Home Inspector Does NOT Check
Standard home inspections do not include:
- Inside walls, ceilings, or under floors (only visually accessible areas)
- Septic systems (requires a separate specialist)
- Wells (requires water quality test and pump inspection)
- Pools or spas (often a separate add-on or inspection)
- Mold (visual indicators only; lab testing is separate)
- Radon (requires a separate radon test)
- Lead paint or asbestos (separate testing required)
- Sewer lines (a sewer scope is a separate service)
Specialty Inspections to Consider
| Inspection | When to Consider | Typical Cost |
|---|---|---|
| Sewer scope | Homes 20+ years old | $150–$300 |
| Radon test | All homes, especially with basements | $100–$200 |
| Mold testing | If visual signs or musty odors | $300–$600 |
| Chimney inspection | If home has fireplace/wood stove | $200–$400 |
| Pool/spa inspection | If property has a pool | $150–$300 |
| Septic inspection | If home has a septic system | $250–$500 |
| Pest/termite (WDO) | All homes; required by some lenders | $75–$150 |
| Wind mitigation (Florida) | Florida properties | $75–$150 |
| Foundation specialist | If inspector flags foundation concerns | $200–$500 |
How to Choose a Home Inspector
- Licensing – Most states require home inspectors to be licensed. Verify with your state's licensing board.
- Certifications – Look for inspectors certified by ASHI (American Society of Home Inspectors) or InterNACHI (International Association of Certified Home Inspectors)
- Experience – Ask how many inspections they've completed in your area
- Sample report – A good inspector delivers detailed, organized reports with photos and clear descriptions
- Independence – Your inspector should be independent of the transaction
What to Do With the Inspection Report
Sort findings into three categories:
- Safety hazards – Issues posing immediate risk (CO risk, faulty electrical, structural instability). These should be addressed before or at closing.
- Major defects – Significant issues affecting livability or value (failing HVAC, roof near end of life, water intrusion). Typically negotiated with the seller.
- Maintenance items – Minor issues to budget for after moving in (dirty gutters, worn weatherstripping).
After reviewing the report, you can request repairs from the seller, request a credit applied to closing costs, renegotiate the purchase price, or walk away within your inspection contingency period and recover your earnest money deposit.
Red Flags: What to Watch For
- Foundation cracks or movement – May indicate costly structural repairs
- Evidence of water intrusion or active leaks – Often more extensive than it first appears
- Outdated electrical panels – Federal Pacific or Zinsco panels have documented safety issues and are often flagged by insurers
- Polybutylene plumbing – A pipe material from the 1970s–1990s known for failure; often requires full replacement
- Knob-and-tube or aluminum wiring – May require upgrading for insurance purposes
- Roof at or past end of life – In Florida, a roof older than 20 years may be uninsurable without replacement
- Pest/termite damage – Structural damage from wood-destroying organisms can be extensive
The Bottom Line
A home inspection is not an obstacle — it's your most powerful tool for making an informed purchase. For a few hundred dollars and a few hours of your time, it can save you thousands and give you the confidence to either close on the right home or walk away from the wrong one. Show up to the inspection, take notes, ask questions, and use the findings to negotiate a smart deal.
