Don't know if you have ever watched Mike Holmes - "Holmes on Homes" - he is huge in Canada, and now is on HGTV. He redo's all the mistakes of home reno. His point is, no matter what you have done - for reframing in of a closet - getting a permit is your only protection against poor workmanship. If your closet is on the 1st floor and it is screwed through the carpet, what if you have water damage? Usually they cut out carpet in the corner where the closet will be and screw to the floor. I hope you have a good sub-floor. They will need to make sure the framing base is securely screwed through the floor to the sub-floor to help support the weight. Otherwise, the drywall seams will crack after painting if not well supported. Good luck.
