If the work was done without a permit, this will 'haunt' you when you go to sell.
Permits are required for a lot home renovations. Work done without a permit without being inspected by a certified inspector potentially means the work is not only done incorrectly, but also goes to a safety or issues, if there is a fire in the house that originates from the unpermitted area, the insurance company can say they won't pay. When you go to sell, you have to disclose the unpermitted work.
Its a nightmare for sure
NC is a caveat emptor state (buyer beware) and Closing constitutes acceptance of the home in it's then existing condition; it is generally the responsibility of the Buyer to satisfy themselves that a property is in an acceptable condition and suitable for their intended use - or to hire someone like a home inspector or qualified contractor or engineer to help them make that determination. An NC attorney would have to review your situation and make a specific determination, however. If you appreciate an answer, please give "thumbs up".
