An open building permit means the work was never signed off, and a buyer's lawyer will ask about it before closing because it affects financing and the home's legal status. Your lawyer confirms the tax and title status through Information Services Corporation before the sale closes, and any arrears are usually paid out of your proceeds.
None of this stops a sale outright. Buyers regularly purchase homes with open permits or tax arrears once the numbers are accounted for honestly, and disclosing the issue upfront is far better for your price than having a buyer's inspector find it later, at a cost that typically runs $400 to $600.
