Dave,
In NJ all new installations require permit,
and yes even one outlet, If you want to gamble that nothing will happen, and you are willing to assume all the liability of any loss. then It's on you.
Remember it's the underwriter that wants the inspections, and the homeowner will be the first to hit you with legal action, when his insurance does not pay, and it could be a total loss or loss of life, pretty serious stuff, and yes there are those, that gamble that nothing will happen, not the crowd to follow.
