A home inspection cost calculator is a free online tool that estimates your inspection fee before you ever contact an inspector. You enter your property details — square footage, home age, foundation type, number of HVAC systems, and ZIP code — and the calculator returns an accurate cost estimate based on real industry pricing data.
Use the home inspection cost calculator above to estimate your price in under 60 seconds. The result reflects what licensed, ASHI-certified and InterNACHI-certified inspectors in your area typically charge for a standard residential inspection. It is not a guaranteed quote, but it is a reliable number to budget around.
Based on industry data compiled from certified home inspectors and national cost surveys from sources including Angi and the American Society of Home Inspectors (ASHI), our estimator reflects 2025 and 2026 pricing standards across all major U.S. markets.
Using our free home inspection cost estimator takes less than a minute. Follow these steps:
Enter the total square footage of the home. Include the finished basement if applicable — but not unfinished attic space.
Select the age of the home. Older homes cost more to inspect because they require more time and expertise.
Choose your foundation type — slab, crawlspace, or basement. Crawlspaces add inspection time and cost.
Enter the number of HVAC systems. Each additional unit increases your total.
Select any add-on services you want — radon testing, mold inspection, sewer scope, thermal imaging, or pool inspection.
Enter your ZIP code so the calculator can apply regional pricing to your estimate.
Once you have entered your details, use the home inspection cost calculator above to see your instant estimate. If the number surprises you in either direction, the sections below explain exactly what drives the price.
The national average home inspection cost is $340 to $420 for a standard single-family home under 2,000 square feet. This figure comes from aggregated pricing data across thousands of inspections completed by ASHI and InterNACHI-certified inspectors in markets across the United States.
Here is what most homebuyers actually pay by home size:
| Home Size | Typical Cost Range |
|---|---|
| Homes under 1,000 sq ft | $250 to $310 |
| Homes from 1,000 to 1,500 sq ft | $300 to $360 |
| Homes from 1,500 to 2,000 sq ft | $340 to $400 |
| Homes from 2,000 to 2,500 sq ft | $390 to $450 |
| Homes from 2,500 to 3,000 sq ft | $430 to $510 |
| Homes from 3,000 to 4,000 sq ft | $500 to $620 |
| Homes from 4,000 to 5,000 sq ft | $600 to $750 |
| Homes over 5,000 sq ft | $750 and above |
Use the home inspection cost calculator above to get the exact estimate for your home size and location — these ranges are national averages and your local market may vary.
The home inspection cost per square foot typically ranges from $0.10 to $0.14 for square footage above the inspector's base rate. Inspectors set a flat base fee that covers the first 1,000 to 1,300 square feet of the home. Every additional square foot adds a smaller incremental cost on top.
Smaller homes carry a higher effective cost per square foot because the inspector's fixed costs — travel time, setup, equipment, and report writing — stay the same regardless of home size. As square footage increases, those fixed costs spread across more area and the per-square-foot rate decreases.
This is why a 900-square-foot condo might cost $280 while a 4,500-square-foot home costs $680 — the total rises, but the per-square-foot rate falls. The home inspection cost calculator above automatically applies this tiered pricing formula to give you an accurate total based on your specific square footage.
Square footage is the single biggest driver of home inspection pricing. Larger homes take more time to walk through, evaluate, and document. A thorough inspection of a 4,000-square-foot home typically takes four to five hours on-site. A 1,200-square-foot condo takes under two hours. More time means higher cost.
Older homes require more careful and time-consuming inspection. Aging electrical panels, galvanized supply pipes, outdated HVAC equipment, and deteriorating roofing materials all demand closer attention from a qualified inspector. Most inspectors following ASHI and InterNACHI inspection standards add a surcharge of $25 to $100 for homes older than 30, 50, or 70 years. A home built before 1978 also triggers lead paint awareness protocols.
Crawlspace foundations add to the inspection cost because the inspector must physically enter a confined, often damp, and sometimes pest-affected space to evaluate floor joists, beams, vapor barriers, insulation, and moisture conditions. Most inspectors charge $50 to $100 extra for crawlspace access. Slab-on-grade foundations do not carry this additional charge.
A standard single-family home has one heating and cooling system. Larger homes, zoned climate systems, or multi-unit properties may have two or more. Each additional HVAC unit adds roughly $25 to $50 to the home inspection cost total. The inspector must evaluate every thermostat, air handler, and condenser unit separately.
Inspectors in high-cost urban markets charge higher base rates than those in rural areas. Local real estate market conditions, state licensing requirements, and inspector certifications also affect pricing. Properties far from the inspector's base location may carry a mileage surcharge — typically $0.75 to $1.80 per mile beyond 20 miles.
A guest house, garage apartment, or accessory dwelling unit with its own kitchen, bathroom, and sleeping area counts as a separate dwelling in most inspection pricing models. Inspectors generally charge $50 to $100 per additional dwelling unit. Detached garages without living quarters carry a smaller square-footage-based add-on.
The standard home inspection report produced in accordance with ASHI Standards of Practice and InterNACHI inspection guidelines covers the visible and accessible components of the home. Specialized testing like radon, mold, sewer, or pool inspection requires separate services and adds to the home inspection cost total.
These are the most commonly requested add-on services and what they typically cost nationwide:
Radon is the second leading cause of lung cancer. Required by lenders in many states. Strongly recommended in high-prevalence regions.
Essential when visible moisture damage, water stains, or musty odors are present.
A camera inspection of the sewer lateral line. Critical for homes older than 30 years or with mature trees near the sewer line.
Checks for lead, bacteria, nitrates, and other contaminants. Required for homes on private wells.
Evaluates pool equipment, plumbing, electrical connections, and structural condition.
Reveals hidden moisture, missing insulation, and electrical hot spots invisible to the naked eye. Often bundled with the main inspection at a discount.
Level 1 or Level 2 inspection per NFPA 211 standards. Critical for wood-burning fireplaces.
For homes not connected to municipal sewer. Identifies tank capacity, leach field condition, and system failures.
Uses precision instruments to measure foundation movement. Recommended in regions with expansive clay soils.
Verifies that seller-agreed repairs were completed correctly before closing.

A standard 2,000-square-foot single-family home on a slab foundation with one HVAC system costs $350 to $450 to inspect. This is the most common scenario in the U.S. residential market and the baseline most home inspection cost calculators use as their starting point.
Condo and townhome inspections typically cost $200 to $350. The inspector evaluates only the interior unit and the systems within the unit boundaries. The roof, building exterior, and common areas are the HOA's responsibility and are not included in the property inspection report.
New construction inspections cost $300 to $500. Many buyers also commission phase inspections during the build — a framing inspection before drywall installation and a pre-drywall electrical inspection. These add $150 to $250 each but catch builder errors while corrections are still free. A final new construction inspection before closing is always recommended, even on properties built by reputable developers.
Homes built before 1960 typically cost $400 to $700 or more to inspect. These properties require an experienced inspector familiar with period-appropriate construction — balloon framing, knob-and-tube wiring, galvanized plumbing, and original HVAC systems all require more careful evaluation. InterNACHI and ASHI-certified inspectors with specific experience in older homes deliver the most thorough property inspection reports for these properties.
A duplex inspection runs $400 to $600. Each additional unit adds $60 to $100. A four-unit residential property may cost $700 to $950 for a complete inspection. Real estate investors who skip inspections on multi-family acquisitions frequently discover plumbing failures, electrical deficiencies, or code violations that eliminate months of projected rental income.
Home inspection pricing varies significantly across the United States. Here are the typical ranges by region based on current industry data:
| Region | Typical Cost Range | Notes |
|---|---|---|
| Northeast (NY, MA, CT, NJ) | $400 to $600 | High labor costs, dense older housing stock, strict licensing requirements |
| Southeast (TX, FL, GA, NC) | $300 to $450 | Humidity, wood rot, and hurricane zone considerations |
| Midwest (IL, OH, MI, MN) | $280 to $420 | Older homes common, cold climate HVAC evaluation, frequent basement inspections |
| West Coast (CA, WA, OR) | $400 to $650 | High cost of living, seismic zone considerations, wildfire area disclosures |
| Mountain West (CO, UT, AZ, NV) | $320 to $480 | High radon prevalence, expansive soils, desert HVAC systems |
| Gulf South (LA, MS, AL) | $280 to $400 | Moisture concerns, flooding history, termite activity, older construction |
A fair home inspection price reflects the complexity of the property and the qualifications of the inspector — not the lowest number you can find on a search result. Before you book, verify these things:
Confirm the inspector carries Errors and Omissions (E&O) insurance and general liability coverage. Uninsured inspectors expose you to significant risk if they miss something major.
Check their certification. ASHI (American Society of Home Inspectors) and InterNACHI (International Association of Certified Home Inspectors) are the two most respected credentialing bodies in the U.S. residential inspection industry. Both require inspectors to follow documented Standards of Practice and complete ongoing education.
Ask for a sample property inspection report. A professional report includes photos, condition ratings, and clear descriptions of every deficiency found. Vague or one-page reports are a red flag.
Confirm they allow you to attend the inspection. Walking through the home with the inspector — asking questions in real time — is one of the most valuable parts of the entire process. Any inspector who discourages your attendance is not worth hiring.
Read Google, Angi, and Yelp reviews — specifically for comments about thoroughness, communication, and report quality — not just star ratings.
Used by homebuyers across the country to estimate real inspection costs, our home inspection cost calculator above takes all of these variables into account and gives you a reliable benchmark before you start contacting inspectors.
A home inspection completed according to ASHI Standards of Practice and InterNACHI inspection guidelines covers all of the following:
Most inspectors offer a discount when you order radon testing, thermal imaging, or a sewer scope alongside the primary inspection. Ordering them separately from different vendors almost always costs more overall.
Many independent inspectors reduce their fee by 5 to 10 percent for buyers who pay in full at the time of booking rather than at the inspection.
A locally based inspector does not charge a travel or mileage surcharge, and local inspectors typically have deeper knowledge of regional building practices and common defects in your market.
If repairs are negotiated after your inspection, you will need a reinspection to verify the work. Most professional inspectors charge $100 to $150 for this follow-up visit — not a new full inspection fee.
This is the most expensive mistake buyers make in competitive markets. A home inspection contingency protects you from purchasing a property with serious hidden defects. The home inspection cost — $300 to $500 — is always worth the protection it provides.
