The electrical permit is always just walk in, pay fee, get permit. It can be quite diferent for the GC to get the main permit. On a City of Atlanta job we're wiring the city approved the plans and issued the permit for a detached 3 car garage and apartment. Then the building inspector slapped a stop work order after at the drywall stage and ordered them to go back to review. In the end, they had to get a variance because the project was 3% larger than allowed in comparison to the main house.
