Home Inspection Cost Calculator — 2026 Buyer Price Estimator

A standard home inspection costs $300 to $500 for most US buyers in 2026, with a national average around $343 and a typical range of $296 to $424. Price scales with square footage at roughly $0.10 to $0.20 per square foot, so a home under 1,000 sqft can run about $200 while a 3,000+ sqft house lands at $400 to $600. High-cost metros like Hartford average near $489, while lower-cost markets like Detroit sit closer to $294.

• National average: about $343 per inspection
• Typical range: $300 to $500 for a standard inspection
• Per square foot: $0.10 to $0.20
• Under 1,000 sqft: around $200; over 3,000 sqft: $400 to $600
• High-cost metros run 20 to 40 percent above the national average

Add-on tests are billed on top of the standard inspection because hazards like radon, termites, and sewer damage are not part of a basic visual inspection. Radon testing runs $125 to $200, a termite or wood-destroying-insect inspection $75 to $125, a sewer scope $150 to $350, and a mold test $150 to $300. Bundling several add-ons with the base inspection usually pushes the total to $600 to $1,200, and each test can flag a five-figure repair before you close.

• Radon test: $125 to $200
• Termite / wood-destroying-insect (WDI): $75 to $125
• Sewer scope: $150 to $350
• Mold test: $150 to $300
• Thermal imaging: $100 to $150

Square footage is the biggest driver, but age, foundation type, and location all move the price. Older homes take longer to inspect and often need more add-on testing. A full basement or crawlspace adds access work that a slab does not, and high-cost labor markets run 20 to 40 percent above the national average. Detached structures, pools, and outbuildings are usually inspected for an extra fee.

• Square footage: each 1,000 sqft adds roughly $50 to $100
• Home age: 50+ year homes often need extra add-on tests
• Foundation: basements and crawlspaces cost more than slabs
• Region: high-cost metros add 20 to 40 percent
• Extras: pool, septic, or detached garage add $75 to $200 each

Yes for almost every buyer. A $400 inspection routinely uncovers issues worth thousands to tens of thousands of dollars in negotiating leverage or avoided repairs. A $150 radon test can save a $1,000 to $2,500 mitigation surprise, and a $200 sewer scope can flag a $15,000 line replacement before you own it. Inspection results are commonly used to renegotiate price or request repairs, so the fee usually pays for itself many times over.

• Typical fee: $300 to $500 plus optional add-ons
• Radon mitigation avoided: $1,000 to $2,500
• Sewer line replacement avoided: up to $15,000
• Inspection findings are common grounds for price renegotiation
• Waiving inspection shifts all repair risk to the buyer

The buyer almost always pays for the home inspection, typically $300 to $600 with add-ons, because it protects the buyer's purchase decision. The fee is usually paid directly to the inspector at the time of service, separate from closing costs. Some sellers order a pre-listing inspection to head off surprises, but in a standard transaction the buyer commissions and pays for their own independent inspection.

• Buyer pays: $300 to $600 with common add-ons
• Paid to the inspector at service, not rolled into closing
• Seller pre-listing inspection: optional, same price range
• Independent inspector keeps the report objective
• Lenders may require specific reports (e.g. WDI in some states)
