Basement development?

[Tarolisol]

Me and my Father developed our basement a couple years ago and we never got any permits, but we did have a friend who was an electrition check all or wiring before we connected the power. Its not a hard DIY if you have a few extra hands, the hardest part i found was caring the drywall into the basement, and taping mudding the drywall, that was horribbly dusty.
