...or a homeowner trying to do the work an EC pulled a permit for.
In Florida it is more likely to go the other way. A homeowner can pull permits and sometime "side jobs" and "handyman" work get permitted that way.
In real life, virtually anyone can do the work if a licensed contractor pulls the permits. We don't have state wide journeyman licenses although some municipalities do.
The only real requirement when the homeowner pulls the permit is insurance and taxes for the worker.
There is also some voodoo in what triggers the need for "engineered" plans here. I really think it is up to the plan review staff in each community but there may be some guidelines.
