Home Inspection Cost Calculator

Inspection costs are heavily tied to local labor rates, liability insurance costs for inspectors, and regional real estate demand. In 2026, inspectors in states like California or New York pay significantly higher premiums for professional insurance, which is passed on to the buyer.

A standard inspection covers the “big five”: **Structure** (foundation/walls), **Roof**, **Electrical**, **Plumbing**, and **HVAC** (Heating/Cooling). It also includes a general look at doors, windows, and built-in appliances.

In almost all cases, the buyer pays for the inspection. This ensures the inspector is working in the buyer’s best interest to uncover potential issues before the sale is finalized. Some sellers perform a “pre-listing inspection” to avoid surprises during negotiations.

A larger home takes more time to inspect. An inspector has more windows to check, more outlets to test, a larger roof area to examine, and often more complex plumbing and electrical systems.

Yes. Historic or vintage homes often have unique challenges like outdated wiring (knob and tube), aging pipes (galvanized steel), and structural settling. Inspectors must take more care and time, which results in an “Age Surcharge.”

If the home was built before 1980, a sewer scope is highly recommended. It detects cracks, tree root intrusions, or “bellies” in the main line that can cost over $10,000 to repair if discovered later.

According to the EPA, 1 in 15 US homes has elevated radon levels. Radon is an odorless, radioactive gas and the second leading cause of lung cancer. If the home has a basement or crawlspace, testing is essential.

A “bad” report isn’t a failure—it’s a tool for negotiation. You can ask the seller to make repairs, request a credit toward your closing costs, or, if the issues are severe enough (and you have an inspection contingency), you can walk away from the deal.

A standard 2,000 sq. ft. home typically takes 2 to 4 hours on-site. The detailed digital report is usually delivered to the buyer within 24 to 48 hours after the visit.

Inspectors will point out visible “mold-like substances,” but air quality testing for mold or lab testing for asbestos is usually a specialized add-on service and is not included in the base fee.
