Home Inspection Cost Estimator
Estimate home inspection costs based on property size, age, and additional inspections.
Budget for all inspection types before buying a home.
Home inspection cost estimation calculates the expected price of a professional home inspection based on the property’s square footage, age, location, and any specialty inspections required.
Core formula: Base Inspection Cost = Base Rate + (Square Footage × Per-Sq-Ft Rate)
Standard pricing structure (2025 US averages):
- Base fee: $200–$350 (covers first 1,000–1,500 sq ft)
- Per additional 500 sq ft: $25–$50
Average inspection costs by home size:
| Home Size | Typical Cost Range |
|---|---|
| Under 1,000 sq ft | $200–$300 |
| 1,000–1,500 sq ft | $275–$375 |
| 1,500–2,000 sq ft | $300–$425 |
| 2,000–2,500 sq ft | $350–$500 |
| 2,500–3,000 sq ft | $400–$550 |
| 3,000–4,000 sq ft | $450–$650 |
| 4,000+ sq ft | $550–$900+ |
Specialty inspection add-ons:
| Inspection Type | Additional Cost |
|---|---|
| Radon test | $100–$200 |
| Mold assessment | $200–$600 |
| Sewer scope | $125–$300 |
| Chimney inspection | $100–$250 |
| Pest/termite inspection | $75–$150 |
| Pool/spa inspection | $100–$200 |
| Well and septic | $200–$500 |
| Roof-only inspection | $100–$250 |
Worked example: A 2,200 sq ft home, 35 years old. Buyer requests radon and sewer scope. Base inspection: $425 Radon test: $150 Sewer scope: $200 Total: $775
Is it worth it? Absolutely. The average home inspection finds issues that lead to $14,000 in negotiated price reductions or seller repairs (according to a 2023 HomeAdvisor survey). Skipping an inspection to save $350–$500 can result in discovering a $15,000 HVAC replacement or $30,000 foundation problem after closing.
