A home inspection is the few hundred dollars that protects a several-hundred-thousand-dollar decision. It is also the moment when a house stops being a set of listing photos and becomes a physical object with a roof age, a furnace history, and a basement that has seen some weather. Here is what to expect from a home inspection — how it works, what it costs, what it covers, and just as important, what it does not cover.
How Much Does a Home Inspection Cost?
Home buyers typically schedule and pay for the inspection. HomeGuide puts the average home inspection at $200 to $500, with a national average around $340 and luxury or high-cost regions running $800 or more (HomeGuide). HomeAdvisor’s data shows a similar band of $296 to $424 on average, with popular cities commonly landing between $300 and $450 (HomeAdvisor). Size, age, and outbuildings push the number up; travel fees may apply in rural areas.
Add-on services are priced separately. Older homes may need evaluation for materials like asbestos or lead paint, which can add $100 to $200, while infrared thermal imaging — useful for spotting moisture and insulation gaps — runs about $300 to $500 (HomeGuide).
What a Standard Inspection Covers
A general home inspection is a visual, non-invasive examination of the home’s major systems, usually following standards of practice published by national inspector associations such as ASHI and InterNACHI. A typical report walks through:
- Structure and foundation: framing, floors, walls, crawlspaces, basements, and visible signs of settlement or water intrusion.
- Roof: shingles or other covering, flashing, gutters, and visible leaks — from the ground or a safely accessible vantage point. Roof age is one of the biggest cost signals in any report; our roof replacement cost guide shows what a full replacement runs.
- Plumbing: supply and drain lines, water heater, fixtures, and visible leak evidence. If the report flags supply-line or drain issues, our guide to common plumbing problems explains which ones are urgent.
- Electrical: service panel, branch wiring, outlets, and GFCI protection.
- HVAC: heating and cooling equipment, apparent age, and operation. Our HVAC maintenance guide covers what these systems need once they are yours.
- Interior and exterior: windows, doors, siding, grading and drainage, decks, stairs, and appliances that convey.
How Long It Takes and How to Prepare
Expect two to four hours for a typical single-family home, longer for large or older properties. The buyer usually attends the last portion — the best use of that time is to follow the inspector, see the systems with your own eyes, and ask what they would fix first. You do not need to do anything to the seller’s home, but you should bring a notebook and, if possible, your agent.
What a Home Inspection Does Not Cover
Inspectors do not open walls, and the report is not a guarantee. Common exclusions to plan for separately:
- Radon: the EPA and the U.S. Surgeon General recommend testing all homes below the third floor for radon, and the agency’s home buyer guidance says to fix homes at or above 4 picocuries per liter (epa.gov). Testing is inexpensive and simple; mitigation systems are a common negotiation item.
- Sewer and septic scope: camera inspections of the main sewer line are a separate service and are money well spent on older homes.
- Termites and pests: many regions require a separate wood-destroying organism inspection.
- Mold, well water, and septic certification: specialist tests, each ordered as needed.
- Code compliance and permits: an inspection is not a code inspection, and unpermitted work is a real risk on renovated homes.
Choosing the Right Inspector
Inspectors are not all alike. Look for licensing or certification where your state requires it, membership in national associations that publish standards of practice, errors-and-omissions insurance, and sample reports you can read before booking. Ask how many inspections they have performed, whether they welcome you to attend, and how quickly the written report arrives — usually within 24 to 48 hours. Your agent’s recommendations are a starting point, but remember who pays the agent; an inspector you chose independently answers only to you.
How to Read the Report
Every report reads like a catastrophe at first glance because inspectors are paid to find things. Sort findings into three buckets: safety and structure (electrical hazards, active leaks, foundation movement, failing roof), major systems nearing end of life (a 20-year-old furnace, an aging water heater), and cosmetic or maintenance items (caulk, filters, grading tweaks). The first bucket changes the negotiation; the second changes your budget; the third is your first weekend of ownership — exactly the kind of item a good home maintenance checklist absorbs.
Using the Report in Negotations
Common strategies include asking for repairs before closing, requesting a credit at closing, or adjusting the price. Ask for the important things, not every line item — sellers respond to safety and structural issues, and buyers who nickel-and-dime over $50 items often lose goodwill they need later. If the inspection reveals a project you would rather do yourself after closing, a credit is usually cleaner than a seller-completed repair.
Special Cases: New Construction and Condos
New homes deserve inspections too. HomeGuide lists new-construction inspections at $100 to $400, pre-drywall inspections at $100 to $400, and an 11-month warranty inspection at $250 to $350 — scheduled just before the builder’s warranty expires so the builder, not you, pays for what the inspector finds (HomeGuide). Condo inspections run about $200 to $250 for an average unit, focusing on the interior and the unit’s systems, since the building envelope and roof are the association’s responsibility.
When your inspection turns up contractor work — a roof at end of life, an aging furnace, a sewer repair — find vetted local professionals in our business directory before you need them urgently.
Frequently Asked Questions
Do I have to be there for the inspection?
You are not required to attend, but you should at least join the final walkthrough. Seeing the water stains, the panel, and the attic with the inspector is worth more than reading the report cold.
How long do I have to get an inspection?
Whatever your contract says. Most purchase agreements give buyers an inspection period of a week or two after acceptance; negotiate it explicitly and calendar the deadline, because missing it generally waives your right to renegotiate.
Is a home inspection worth it on new construction?
Yes. New homes can have installation defects, grading problems, and missed items — which is why builders offer warranty periods and why an 11-month inspection before the warranty expires is standard advice.
Should I skip the inspection to win a bidding war?
Rarely. Waiving the inspection contingency can leave you with five-figure surprises on a system the seller never disclosed. If competition demands concessions, consider an information-only inspection instead, or limit the contingency to major structural and safety defects.
What if the report is full of problems?
That is the system working. Decide which items are deal-breakers, which are negotiation points, and which are normal ownership. If the big-ticket items overwhelm your budget, walking away is a legitimate outcome — inspections exist to make that decision possible before, not after, the sale is final.
