I pulled 2 permits at my last house. The 1st permit was for a kitchen addition/remodel. This included electric and the building addition. I did all the drawings myself and submitted for permit. They came back with a few clarifications as well as who was doing the work. I told them at that time I haven't made the decision to award or do the work myself. All they said after that was if you sub it out please send over a workers comp insurance cert. I ended up doing all the work myself.
I also pulled a permit for a pole building. Pole building company supplied me with the drawings and there workers comp insurance. No issues there. They did all the work on that reno.
