As you can see, even a simple, small structure in good condition would require at least 3 hours of an inspector's time. Allowing an hour for an assistant and you would expect to pay well over $200 with no allowance for travel, meetings or review by senior staff.
Since only a small percentage of structures fall into this category, you could expect an average cost substantially higher. The following are typical of an inventory of 50 structures or more:
| Weighted Average Age of Network* | Average Insp. $ / Structure |
| < 30 years | 320 |
| 30 - 39 years | 380 |
| 40 - 49 years | 500 |
| 50 years and over | >750 |
* Age weighted proportionate to replacement value.
