Is there anything one would encounter in a remodeling project that has to be done by a licensed plumber or electrician to be legal? A friend had that idea, but I thought it was bunk. Also, what about permits? I chose to do a bathroom remodel, removing all fixtures and going back to the studs. I've added new electrical components and moved plumbing in the process. I'll finish with a heated floor, tiled shower, and all new fixtures and cabinets. I'm guessing the scope would require a permit. On the other hand, if everything is done correctly, where is the fault? Thank you!
