How to Use This Calculator
- Enter the structure total square footage and the number of accessible areas (crawl, attic, garage).
- Set the inspection rate per square foot or flat fee based on your market.
- Input travel time and mileage to the property.
- Review the Inspection Fee Estimate and the Total Job Cost with travel.
- Use the Minimum Profitable Fee output to ensure your pricing covers overhead and time.
How the result changes with Property size (ft²)
| Property size (ft²) | Inspection cost ($) | Inspection time (minutes) |
|---|---|---|
| 5,450 | $261.25 | 152 |
| 17,825 | $570.63 | 337 |
| 32,675 | $941.87 | 560 |
| 45,050 | $1,251.25 | 746 |
What each input means
- Property size (ft²)
- Total heated living area of the property.
- Number of stories
- Number of above-grade floors to inspect.
- Has crawl space (0=No, 1=Yes)
- Crawl space inspection adds time and cost.
- Has basement (0=No, 1=Yes)
- Finished or unfinished basement to inspect.
- Attached garage (0=No, 1=Yes)
- Attached garages share walls and should be inspected.
- Purpose (0=Sale, 1=Maint, 2=Commercial, 3=VA/FHA)

How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersProperty size (ft²) = 2000, Number of stories = 1, Has crawl space (0=No, 1=Yes) = 1, Has basement (0=No, 1=Yes) = 0 = 6 input(s) provided
- Calculate Inspection costInspection cost = (baseFee * storyMultiplier + crawlSpaceSurcharge175 = $175
- Calculate Inspection timeInspection time = (baseTimeMin + crawlTimeMin + basementTimeMin + garageTimeMin) * storyMultiplier100 = 100
- Calculate Areas to inspectAreas to inspect = 4 + stories // exterior, interior per floor, roof eaves, foundation7 = 7
- Calculate Report delivery2 = 2
