If you are a conscientious electrician, the correction notices are few and far between. The expense is minimal when you consider how seldom you have to deal with this situation. In new towns I usually talk with the inspector to find out what they're looking for.
We have a sharp inspector on the commercial work I'm doing. He wrote a correction notice at rough for one knock-out on a junction box (I hadn't installed the connector yet). Of course he also wrote something for all the other trades. The general pays the reinspection fee.
In a way, the inspector is doing us a favor by creating a checklist for all the trades to get through that inspection. We do what's on the list and then it passes. It's well worth the small reinspection fee.
