Home Inspection Cost Calculator

Estimate the total cost of a home inspection including optional specialty tests like radon and termite inspections. Plan your inspection budget based on the home's size, age, and the specific tests you need.

The home inspection cost calculator estimates the total fees you will pay for a professional home inspection and any additional specialty tests, based on the size, age, and characteristics of the property. The base inspection fee is primarily driven by the home's square footage. Most inspectors charge a flat fee that increases with home size in tiers. A typical general home inspection costs $300 to $400 for homes under 1,500 square feet, $400 to $500 for homes between 1,500 and 2,500 square feet, and $500 to $700 for homes over 2,500 square feet. The calculator assigns a base cost using these industry-standard ranges. Home age affects the inspection cost because older homes require more thorough evaluation. Homes built before 1978 may need lead paint testing, homes over 25 years old may warrant closer examination of the roof, electrical, and plumbing systems, and homes over 40 years old may have foundation concerns that require additional time. The calculator applies a modest surcharge for older homes to account for the additional inspection time. Specialty inspections are separate tests that can be added to the general inspection. A radon test typically costs $125 to $200 and measures the level of radon gas in the home, which is a significant health concern in many regions. A termite and wood-destroying insect inspection costs $75 to $150 and checks for active infestations and damage. Other common add-ons include sewer scope inspection ($200 to $400), mold testing ($200 to $500), and well and septic testing ($200 to $400 each) for rural properties. The calculator totals the base inspection fee plus any specialty tests you select to give you a complete inspection budget. This is a one-time cost typically paid at the time of inspection, before closing, and is not usually included in closing costs covered by the lender.

Never skip the home inspection to save a few hundred dollars. A thorough inspection can uncover issues that cost tens of thousands to repair, from foundation cracks and roof damage to faulty electrical systems and plumbing leaks. The inspection report also gives you negotiating leverage to request repairs or a price reduction from the seller. The $400 to $600 you spend on an inspection is one of the best investments in the entire home buying process.

Choose your inspector carefully rather than simply going with the cheapest option or the one your real estate agent recommends. Look for inspectors certified by organizations such as ASHI (American Society of Home Inspectors) or InterNACHI (International Association of Certified Home Inspectors). Read recent reviews, ask how long the inspection takes (a thorough inspection of a typical home should take 2 to 4 hours), and confirm they carry errors and omissions insurance.

Attend the inspection in person if possible. Walking through the home with the inspector gives you a firsthand understanding of the property's condition and lets you ask questions in real time. The inspector can point out maintenance items and explain the severity of findings in context, which is far more informative than reading the written report alone. Most inspections take 2 to 4 hours, and this is time well spent.

Consider radon testing as essential rather than optional, especially in regions with known radon exposure. Radon is an odorless, colorless gas that is the second leading cause of lung cancer, and it can be present in any home regardless of age or construction type. Testing costs $125 to $200, and if elevated levels are found, radon mitigation systems typically cost $800 to $1,500 to install, which can be negotiated as a seller concession.

A standard home inspection costs $300 to $600 depending on the home's size, age, and location. Homes over 2,500 square feet or older than 30 years typically cost more due to additional inspection time. Specialty tests like radon, termite, sewer scope, and mold add $75 to $500 each. The total with add-ons typically ranges from $500 to $1,200.

The buyer typically pays for the home inspection, and it is due at the time of the inspection rather than at closing. This is a non-refundable cost even if you decide not to purchase the home. In some markets, sellers provide pre-listing inspections, but buyers should still consider getting their own independent inspection.

You can negotiate with the seller to make repairs, reduce the sale price, or provide a closing cost credit. For serious issues, you may exercise your inspection contingency to withdraw from the contract with your earnest money returned. Minor findings are normal in any home, so focus on structural, safety, and high-cost items when deciding how to respond.

Termite inspections are strongly recommended and required by some lenders, especially for VA and FHA loans. Termites cause billions of dollars in property damage annually, and damage is often hidden inside walls and foundations. The $75 to $150 cost is minimal compared to the potential repair bills, which can easily reach $5,000 to $15,000 for significant infestations.

A thorough general inspection takes 2 to 4 hours depending on the home's size, age, and condition. Larger or older homes take longer because there is more to examine. Add-on tests like radon require 48 hours for results, though the test setup adds minimal time to the inspection visit. Plan to be present for the full inspection if possible.
