A State agency shall not lease any real property to a person who is delinquent in paying any real property taxes on a leasehold estate under Section 9-195 of the Property Tax Code. If a State agency receives notice that a lessee of property under the agency's control is delinquent in paying property taxes, the agency shall notify the lessee that the lessee has 60 days to pay the delinquent taxes, plus penalties and interest, if any, or the lease shall be terminated. If the lessee fails to submit proof to the agency that the lessee has paid the taxes, penalties, and interest, the agency shall terminate the lease. A person whose lease was terminated under this Section is not allowed to lease State-owned real property or bid on a lease for State-owned real property for a period of 2 years after the termination of the lease.
Within 60 days after entering into an agreement to lease State-owned real property, the State agency leasing the State-owned real property shall notify the county clerk of the county in which the real property is located of the name and mailing address of the lessee.
