Home Inspection Cost Estimator
Estimate your home inspection cost based on square footage, property age, home type, and optional add-on inspections.
Formula
Base Cost = max($300, Square Footage × Base Rate per sq ft)
Base Rate: $0.10–$0.17/sq ft (decreases as size increases)
Subtotal = (Base Cost × Property Type Multiplier) + Age Surcharge + Stories Surcharge
Total = Subtotal + Sum of Selected Add-On Inspections
Estimated Range = Total × 0.85 to Total × 1.15
Property Type Multipliers: Single-Family ×1.00 | Condo ×0.80 | Multi-Family ×1.35 | Mobile ×0.90
Age Surcharges: 0–5 yrs: $0 | 6–15 yrs: $25 | 16–30 yrs: $50 | 31–50 yrs: $100 | 51–75 yrs: $175 | 75+ yrs: $250
Stories Surcharges: 1 story: $0 | 2 stories: +$50 | 3+ stories: +$100
Assumptions & References
- Base rates derived from national averages reported by the American Society of Home Inspectors (ASHI) and HomeAdvisor/Angi (2024).
- National average home inspection cost is approximately $300–$500 for a typical 2,000 sq ft single-family home.
- Older homes require more time due to outdated systems (knob-and-tube wiring, galvanized pipes, asbestos risk), justifying age surcharges.
- Multi-family homes require inspection of multiple units, common areas, and shared systems, increasing cost significantly.
- Add-on prices reflect typical national averages: Radon ($100–$200), Mold ($200–$600 for basic air sampling), Sewer Scope ($100–$250), Termite/WDO ($75–$150), Pool ($100–$150), Roof Certification ($100–$200).
- The ±15% range accounts for regional labor cost differences, inspector experience, and local market conditions.
- This estimate does not include specialized inspections such as asbestos, lead paint, chimney, or HVAC-specific assessments.
