According to Article 705 of the Civil Code, the lease term of the house shall not exceed 20 years. If it has been more than 20 years, the excess part shall be invalid. At the end of the lease term, the parties may renew the lease contract, but the agreed lease term shall not exceed 20 years from the date of renewal. That is to say, the maximum term of the housing lease contract, including the renewal of the housing lease contract, is 20 years. The management of the competent real estate department runs through the whole lease period, and the housing lease period is subject to the supervision and management of the competent real estate department. Therefore, the lease management period of commercial housing is the same as that of commercial housing, with a maximum of 20 years and a maximum of 20 years after renewal. The specific management period depends on the lease term agreed in the lease contract.
