What a home inspection actually does
A home inspection is a visual check of the major systems and structure of a home, done by a licensed or certified inspector. The inspector walks the home for 2 to 4 hours, opens the electrical panel, runs the heating and cooling, tests plumbing fixtures, checks the roof, foundation, attic, and insulation, and looks for signs of water damage, structural problems, and outdated wiring. The inspector then writes a 30 to 80 page report with photos and findings, delivered within 24 to 48 hours. The buyer uses the report to negotiate with the seller, ask for repairs, or walk away from the deal during the inspection contingency period.
The standard inspection does not cover specialty items like pools, septic tanks, sewer lines, radon, mold, or termites. These are separate add-on inspections that cost extra. The standard inspection also does not cover cosmetic issues like paint, carpet, or landscaping. The inspector notes visible defects only, and does not move furniture, lift carpets, or open walls. Any system that is inaccessible or not visible is noted as such in the report.
How much it costs by home size
For a typical single-family home under 2,000 square feet, the inspection runs 280 to 450 dollars in 2026. The national average sits at 340 dollars according to HomeAdvisor's 2026 cost data. Homes between 2,000 and 3,000 square feet run 350 to 500 dollars. Larger homes over 3,000 square feet run 400 to 600 dollars, and luxury homes over 5,000 square feet can run 600 to 900 dollars. Condos and small apartments under 1,000 square feet run 200 to 350 dollars because there is less to inspect and fewer systems. Multi-family properties with 2 to 4 units run 450 to 700 dollars because each unit gets inspected separately.
The cost depends on three factors. The home's square footage is the biggest one, since larger homes take more time on site. The home's age matters because older homes have more systems to check and more potential issues. The home's location matters because inspectors in high-cost metros charge more to cover their own higher costs. HomeAdvisor tracked the highest average prices in San Francisco, New York, Boston, and Seattle in 2026, and the lowest in smaller Midwestern and Southern metros. Rural areas are also higher because inspectors drive farther to the property, and the travel time gets added to the inspection fee.
The two types of inspectors
The two main types are general home inspectors and specialty inspectors. General home inspectors do the standard visual inspection and write the main report. Specialty inspectors do add-on inspections for radon, sewer, mold, termites, pools, wells, and similar items. Most buyers hire one general inspector for the main report and then add specialty inspectors as needed. A general inspector is usually a member of the American Society of Home Inspectors (ASHI) or the International Association of Certified Home Inspectors (InterNACHI), and follows that organization's standards of practice.
The right way to choose an inspector is to ask for the inspector's license, certifications, and sample report before booking. The best inspectors are full-time professionals who do at least 200 inspections a year, carry errors and omissions insurance, and deliver the report within 24 hours. Avoid inspectors who are also contractors offering to do the repairs, since the conflict of interest leads to inflated findings. Also avoid inspectors who quote a price much lower than the market average, since the low price usually means a shorter on-site visit and a less detailed report.
Add-on inspections worth considering
Five add-on inspections are worth considering in most US markets. Radon testing runs 100 to 200 dollars and is recommended in EPA zones 1, 2, and 3, which cover most of the Northeast, Mid-Atlantic, and Upper Midwest. Radon is the second leading cause of lung cancer, and a simple 48-hour radon test inside the home tells you if you need a mitigation system. Sewer line camera inspection runs 100 to 300 dollars and is recommended for any home built before 1990 with a sewer connection. The camera finds root intrusion, cracks, and bellied pipes that a standard home inspection cannot see. Replacing a sewer line runs 3,000 to 25,000 dollars, so the 200-dollar inspection is cheap insurance.
Termite or wood-destroying-organism inspection runs 75 to 150 dollars and is required by many mortgage lenders in the Southeast, Hawaii, and parts of California. The inspector looks for active termite damage, old damage, and conditions that attract termites. Mold inspection runs 200 to 400 dollars and is recommended if the home has a musty smell, past water damage, or a history of mold. The inspector takes air samples and swabs and sends them to a lab. Well water testing runs 100 to 250 dollars and is required for any home with a private well. The lab tests for bacteria, nitrates, and other contaminants. If the well has unsafe water, the fix is usually a chlorination system or a point-of-use filter, both in the 500 to 1,500 dollar range.
How to use the report
The inspection report is a negotiating tool, not a to-do list. The buyer separates the findings into three buckets. The first bucket is safety issues, which the seller must fix before closing in most states. Examples include exposed wiring, missing smoke detectors, and gas leaks. The second bucket is major repair issues, which the buyer can ask the seller to fix or to credit at closing. Examples include a cracked foundation, an outdated electrical panel, and a failing HVAC system. The third bucket is minor issues, which the buyer accepts and plans to fix after closing. Examples include a dripping faucet, a cracked window, and worn carpet.
The right way to negotiate is to ask the seller to fix the safety and major issues, and to ignore the minor ones. A seller who gets a 50-item repair request usually pushes back and the deal falls apart. A buyer who focuses on the top 5 to 10 issues has a much better chance of getting them fixed or credited. The inspection contingency period is usually 7 to 14 days, which gives the buyer enough time to get the report, choose the priority issues, and submit the request to the seller before the contingency deadline.
Bottom line
A home inspection in 2026 runs 280 to 450 dollars for a typical single-family home, with a national average around 340 dollars. The inspection is paid by the buyer in most markets and is non-refundable. The standard inspection covers the major systems and structure. Add-on inspections for radon, sewer, mold, termites, and well water are worth considering in most cases and cost another 100 to 400 dollars each. The inspection report is a negotiating tool, not a to-do list, and the right approach is to focus on the top 5 to 10 safety and major issues and ignore the minor ones.
