If the situation is as you have mentioned that the fee
for the ground floor was paid for settling the installment of the loan and the installment of the contractor and nothing of the fee is left, there is no Zakah due on the fee if you paid it before the passing of one full lunar year from the due date. (Part No. 9; Page No. 345) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
