Renovation Permits

Hey guys! Don’t chew me up too badly as I’ve never done anything of this caliber. I’m making plans to completely renovate my kitchen and make my 1.5 bathrooms into 2 full bathrooms. To do this they will be taking down and moving walls. It’ll be close to $50k for this project. I’ve been told by the contracts I’ve chosen that it will not require permits if I’m not selling the house within 7 years. This seems odd to me especially with the larger scale of the project. Does anyone have any insight on this? I’m in the Atlanta area if that makes a difference.
