Home Inspection Cost Calculator
Get an instant estimate for a comprehensive home inspection. Factor in home size, age, foundation type, and critical add-ons like Radon and Sewer Scope.
How is Home Inspection Cost Calculated?
The cost of a home inspection is primarily based on the square footage and age of the property. A standard inspection for a 2,000 sq. ft. home typically starts at $350 - $400. Additional fees apply for older homes (pre-1980), crawlspaces, and specialized add-on services like Radon or Termite testing.

Key Factors Influencing Inspection Rates
Property Size & Age
Larger homes take significantly longer to inspect, so inspectors charge by square footage tiers. Similarly, older homes (especially those built before 1950) often have complex systems like knob-and-tube wiring or galvanized plumbing that require more detailed examination, leading to age surcharges.
Foundation & Accessibility
- Slab on Grade: Easiest to inspect; standard pricing applies.
- Crawlspace: Usually incurs a +$100 surcharge due to difficult access, confined space hazards, and the need for protective gear.
- Basement: Typically a smaller surcharge than a crawlspace, but still adds time to check for moisture intrusion and structural issues.
Average Home Inspection Cost by Size
| Home Size (Sq. Ft.) | Average Cost Range | Estimated Time |
|---|---|---|
| Up to 1,000 sq. ft. | $300 – $350 | 2 - 2.5 Hours |
| 1,000 – 2,000 sq. ft. | $350 – $450 | 2.5 - 3 Hours |
| 2,000 – 3,000 sq. ft. | $450 – $550 | 3 - 4 Hours |
| Over 3,000 sq. ft. | +$50 per 500 sq. ft. | 4+ Hours |
Surcharges & Add-on Services
| Description | Estimated Cost | Note |
|---|---|---|
| Older Home (Pre-1950) | +$150 | More complex systems (wiring, plumbing) |
| Crawlspace Access | +$100 | Required for foundation/joist inspection |
| Radon Testing | $150 | 48-hour continuous monitor test |
| Termite (WDO) | $125 | Often required by lenders |
| Sewer Scope | $250 | Camera inspection of main line |
How to Estimate Home Inspection Cost Manually
If you want to double-check your quote or estimate manually, follow these steps using the tables below as a reference:
Step 1: Check the Square Footage
Determine the total square footage of the living area. Most inspectors charge a base fee for homes up to 2,000 sq. ft. and add a surcharge for every additional 500 sq. ft.
Step 2: Account for Home Age
Find the year the home was built. Pre-1950 homes typically have a surcharge due to older wiring (knob-and-tube) and plumbing (galvanized/cast iron), which take longer to inspect.
Step 3: Identify Foundation Type
Does the home have a crawlspace or basement? Crawlspaces are difficult to access and physically demanding to inspect, often adding $100 to the bill.
Step 4: Select Optional Services
Decide if you need Radon, Termite, or Sewer Scope inspections. These are critical for older homes but are billed separately.
Step 5: Apply the Formula
Use this simple formula for a rough guide:
(Base Fee) + (Age Surcharge) + (Foundation Surcharge) + (Add-ons) = Total Cost
Example: A 2,500 sq. ft. home built in 1940 with a crawlspace and Radon test:
($450 Base) + ($150 Age) + ($100 Foundation) + ($150 Radon) = $850.
Frequently Asked Questions
Is a home inspection required?
While not legally mandatory, most lenders require a termite (WDO) inspection. However, skipping a general inspection is risky as it can reveal costly hidden defects like structural damage or faulty wiring.
How long does the inspection take?
A standard inspection typically takes 2 to 4 hours, depending on the size and age of the home. Older homes or those with crawlspaces may take longer.
Can a house 'fail' an inspection?
No. An inspection is a report on the current condition of the home, not a pass/fail test. It highlights safety concerns and necessary repairs to help buyers make informed decisions.
Should the buyer be present?
It is highly recommended. Being present allows the inspector to point out specific issues and explain maintenance tips directly.
What is a 'pre-drywall' inspection?
For new construction, this inspection happens before walls are closed up. It checks framing, electrical rough-ins, and plumbing installation for errors.
Who pays for repairs found during inspection?
The seller is not obligated to fix defects, but the buyer can use the inspection report to negotiate repairs or ask for a price reduction (closing credit).
Does this include a termite inspection?
Usually, a general home inspection does not include wood-destroying organisms (termites) unless specified. It is often a separate add-on service.
What if the house has Radon?
Radon is a colorless, odorless gas that can cause health issues. If levels are high (above 4.0 pCi/L), a mitigation system can be installed, typically costing $1,200 - $2,500.
What is a Sewer Scope?
A camera is run through the main sewer line to check for blockages, root intrusion, or collapsed pipes. This is critical for older homes with clay or cast iron pipes.
Can I inspect the home myself?
You can do a visual walkthrough, but a licensed inspector is trained to identify subtle signs of major issues (like foundation settlement or electrical hazards) that an untrained eye would miss.
