(1) If the stipulated rent or deposit becomes unreasonable due to increase or decrease of taxes, public dues, and other charges on the leased house, or a change in economic circumstances, the party concerned may request any increase or decrease thereof prospectively. In such cases, no request for an increase shall be made within one year after a lease contract is concluded or the rent or deposit agreed upon is increased. <Amended on Jul. 31, 2020>
