Home inspection cost in the US typically runs $300 to $500 for an average-sized home, based on the ASHI figures cited below. The fee rises with square footage, home age, number of stories and high cost-of-living locations, and specialist add-ons such as a termite, radon or sewer inspection are billed on top of that base price.
What Does a Home Inspection Cost in 2026?
A standard home inspection in 2026 typically costs between $300 and $500 for an average-sized home, according to the American Society of Home Inspectors (ASHI). The exact price depends on the home's square footage, age, number of stories, and your geographic market. Smaller homes under 1,000 sq ft may run as low as $250, while larger properties over 3,000 sq ft — or older homes with complex systems — can exceed $700 before any add-ons.
Location is one of the biggest cost drivers. High cost-of-living metros like San Francisco, New York City, and Boston see inspection fees that run 20–50% higher than the national average. Homes built more than 30 years ago also carry a premium because they often require more time and expertise to evaluate aging systems like knob-and-tube wiring, galvanized pipes, and original roofing materials.
Home Inspection Price by Size: Quick Reference
The table below shows the base home inspection rates this estimator uses for a single-story home under 30 years old, before any add-ons. Pick your size row, then read across to your cost-of-living area to get a ballpark house inspection price.
| Home size | Low COL area | Medium COL area | High COL area |
|---|---|---|---|
| Under 1,000 sq ft | $220 – $320 | $250 – $350 | $310 – $430 |
| 1,000 – 1,999 sq ft | $270 – $400 | $300 – $450 | $375 – $565 |
| 2,000 – 2,999 sq ft | $350 – $490 | $400 – $550 | $500 – $688 |
| 3,000+ sq ft | $450 – $630 | $500 – $700 | $625 – $875 |
The calculator then adjusts these ranges: it adds 4–12% for a second, third or fourth story and 12–20% for homes 30 or more years old, because larger and older houses take the inspector longer. Specialist tests are added at their own fees — for example, a termite inspection cost of $75–$150 or a radon test at $125–$200. Use the estimator above to combine all three for your exact home.
Standard vs. Additional Home Inspections
The general home inspection covers the visible, accessible components of the property — roof, foundation, HVAC, plumbing, electrical, insulation, and structural elements. Inspectors certified by ASHI or InterNACHI follow a standardized checklist and typically take 2–4 hours for an average home.
Beyond the standard inspection, buyers often add specialized tests depending on the property's age, location, and history:
- Radon test ($125–$200): Recommended in high-radon states like Colorado, Iowa, Pennsylvania, and Minnesota. The EPA recommends testing all homes regardless of geography.
- Termite/pest inspection ($75–$150): Often required by lenders in the South and Southeast. Undetected infestations can cause tens of thousands in structural damage.
- Mold testing ($200–$600): Advisable for older homes, properties in humid climates, or any home with visible water staining or musty odors.
- Sewer scope ($150–$300): A camera inspection of the main sewer line. Particularly valuable for homes over 30 years old, as clay or cast iron pipes may have collapsed or root intrusion.
- Foundation/structural ($300–$800): A licensed structural engineer's assessment, recommended if the standard inspector flags any cracks, uneven floors, or settling.
According to HUD's home buying guidance, investing in thorough inspections before closing is one of the most cost-effective steps a buyer can take — typically representing less than 0.2% of the home's purchase price while potentially uncovering issues worth far more in repairs.
How to Choose a Home Inspector
Look for inspectors certified by ASHI (American Society of Home Inspectors) or InterNACHI. Both organizations require members to pass written exams, complete continuing education, and adhere to a code of ethics. In most states, inspectors must also hold a state license — check your state's requirements before hiring.
Ask your inspector these questions before booking:
- How many inspections have you completed, and how long have you been in practice?
- Do you carry Errors & Omissions (E&O) insurance?
- Can I attend the inspection? (The answer should always be yes.)
- How quickly will I receive the written report?
- Do you sub-contract any additional tests (radon, mold), and who performs them?
Avoid inspectors recommended exclusively by the seller's agent — a potential conflict of interest. Your buyer's agent or an independent online review platform (Google, Yelp, ASHI's "Find an Inspector" tool) are better sources. Budget around $400–$600 total for a standard inspection plus one or two targeted add-ons, and treat the expense as non-negotiable due diligence before one of the largest purchases of your life.
