It is good to get a permit so the local inspector can get richer....no wait, so you can be safe.
They will check your electrical outlets you install, and heat scources to the room. And make sure anything I mentioned was done to a good standard.
Building inspectors are there to help, and keep us safe. Most folks get the horor stories of bad inspectors and don't tell anyone about what they are doing. Bad move, if there is a problem and someone gets hurt or dies, the blame all comes down on you. And your insurance may not cover you if your house burns to the ground.
Those are the extremes, but that part never makes the newspaper. Being a home inspector myself, I see the bad stuff that happens. That is also one reason I'm here, to head those issues off, and help folks avoid the nasty issues that arise.
That's my rant on inspections, be safe.
I put up a link for framing in another section , check it out.
