This is interesting, as they have chosen to spell it out for the local jurisdiction. As to 'breaking' the law, I am not sure it is considered a law ("Standards of Professional Practice"), or a policy.
But ...
I consider it a problem as an inspector to open and look at electrical work if the owner or company representative is not there to perform the opening themselves, for at least two reasons.
1. Who is to say that something they installed was not 'disturbed' during the process of inspection?
2. What about OSHA requirements for energized work, if in fact the work being inspected (at the time of inspection, the work usually is energized)is energized?
