    Sec. 18-177. Leased low-rent housing abatement.
    (a) In counties of 3,000,000 or more inhabitants, the county clerk shall abate property taxes levied by any taxing district under this Code on property that meets the following requirements:
        (1) The property does not qualify as exempt property
    
under Section 15-95 of this Code.
        (2) The property is situated in a municipality with
    
1,000,000 or more inhabitants and improved with either a multifamily dwelling or a multi-building development that is subject to a leasing agreement, regulatory and operating agreement, or other similar instrument with a Housing Authority created under the Housing Authorities Act that sets forth the terms for leasing low-rent housing.
        (3) For a period of not less than 20 years, the
    
property and improvements are used solely for low-rent housing and related uses.
Property and portions of property used or intended to be used for commercial purposes are not eligible for the abatement provided in this Section.
    A housing authority created under the Housing Authorities Act shall file annually with the county clerk for any property eligible for an abatement under this Section, on a form prescribed by the county clerk, a certificate of the property's use during the immediately preceding year. The certificate shall certify that the property or a portion of the property meets the requirements of this Section and that the eligible residential units have been inspected within the previous 90 days and meet or exceed all housing quality standards of the authority. If only a portion of the property meets these requirements, the certificate shall state the amount of that portion as a percentage of the total equalized and assessed value of the property. If the property is improved with an eligible multifamily dwelling or multi-building development containing residential units that are individually assessed, then, except as provided in subsection (b), no more than 40% of those residential units may be certified. If the property is improved with an eligible multifamily dwelling or multi-building development containing residential units that are not individually assessed, then, except as provided in subsection (b), the portion of the property certified shall represent no more than 40% of those residential units.
    The county clerk shall abate the taxes only if a certificate of use has been timely filed for that year. If only a portion of the property has been certified as eligible, the county clerk shall abate the taxes in the percentage so certified.
    Whenever property receives an abatement under this Section, the rental rate set under the lease, regulatory and operating agreement, or other similar instrument for that property shall not include property taxes.
    No property shall be eligible for abatement under this Section if the owner of the property has any outstanding and overdue debts to the municipality in which the property is situated.
    (b) The percentage limitation on the certification of residential units set forth in subsection (a) shall be deemed to be satisfied in the case of developments described in resolutions adopted by the Board of Commissioners of the Chicago Housing Authority on September 19, 2000, December 17, 2002, or September 16, 2003, as amended, approving the disposition of certain land and buildings on which all or a portion of the developments are or will be situated, if no more than 50% of the units in the development are so certified.
