(35 ILCS 200/15-178)
    Sec. 15-178. Reduction in assessed value for affordable rental housing construction or rehabilitation.
    (a) The General Assembly finds that there is a shortage of high quality affordable rental homes for low-income and very-low-income households throughout Illinois; that owners and developers of rental housing face significant challenges building newly constructed apartments or undertaking rehabilitation of existing properties that results in rents that are affordable for low-income and very-low-income households; and that it will help Cook County and other parts of Illinois address the extreme shortage of affordable rental housing by developing a statewide policy to determine the assessed value for newly constructed and rehabilitated affordable rental housing that both encourages investment and incentivizes property owners to keep rents affordable.
    (b) Each chief county assessment officer shall implement special assessment programs to reduce the assessed value of all eligible newly constructed residential real property or qualifying rehabilitation to all eligible existing residential real property in accordance with subsection (c) for 10 taxable years after the newly constructed residential real property or improvements to existing residential real property are put in service. Any county with less than 3,000,000 inhabitants may decide not to implement one or both of the special assessment programs defined in subparagraph (1) of subsection (c) of this Section and subparagraph (2) of subsection (c) of this Section upon passage of an ordinance by a majority vote of the county board. Subsequent to a vote to opt out of this special assessment program, any county with less than 3,000,000 inhabitants may decide to implement one or both of the special assessment programs defined in subparagraph (1) of subsection (c) of this Section and subparagraph (2) of subsection (c) of this Section upon passage of an ordinance by a majority vote of the county board. Property is eligible for the special assessment program if and only if all of the following factors have been met:
        (1) at the conclusion of the new construction or qualifying rehabilitation, the property
    
consists of a newly constructed multifamily building containing 7 or more rental dwelling units or an existing multifamily building that has undergone qualifying rehabilitation resulting in 7 or more rental dwelling units; and
        (2) the property meets the application requirements defined in subsection (f).
    (c) For those counties that are required to implement the special assessment program and do not opt out of such special assessment program, the chief county assessment officer for that county shall require that residential real property is eligible for the special assessment program if and only if one of the additional factors have been met:
        (1) except as defined in subparagraphs (E), (F), and (G) of paragraph (1) of subsection
    
(f) of this Section, prior to the newly constructed residential real property or improvements to existing residential real property being put in service, the owner of the residential real property commits that, for a period of 10 years, at least 15% of the multifamily building's units will have rents as defined in this Section that are at or below maximum rents and are occupied by households with household incomes at or below maximum income limits; or
        (2) except as defined in subparagraphs (E), (F), and (G) of paragraph (1) of subsection
    
(f) of this Section, prior to the newly constructed residential real property or improvements to existing residential real property located in a low affordability community being put in service, the owner of the residential real property commits that, for a period of 30 years after the newly constructed residential real property or improvements to existing residential real property are put in service, at least 20% of the multifamily building's units will have rents as defined in this Section that are at or below maximum rents and are occupied by households with household incomes at or below maximum income limits.
    If a reduction in assessed value is granted under one special assessment program provided for in this Section, then that same residential real property is not eligible for an additional special assessment program under this Section at the same time.
    (d) The amount of the reduction in assessed value for residential real property meeting the conditions set forth in subparagraph (1) of subsection (c) shall be calculated as follows:
        (1) if the owner of the residential real property commits for a period of at least 10
    
years that at least 15% but fewer than 35% of the multifamily building's units have rents at or below maximum rents and are occupied by households with household incomes at or below maximum income limits, the assessed value of the property used to calculate the tax bill shall be reduced by an amount equal to 25% of the assessed value of the property as determined by the assessor for the property in the current taxable year for the newly constructed residential real property or based on the improvements to an existing residential real property; and
        (2) if the owner of the residential real property commits for a period of at least 10
    
years that at least 35% of the multifamily building's units have rents at or below maximum rents and are occupied by households with household incomes at or below maximum income limits, the assessed value of the property used to calculate the tax bill shall be reduced by an amount equal to 35% of the assessed value of the property as determined by the assessor for the property in the current assessment year for the newly constructed residential real property or based on the improvements to an existing residential real property.
    (e) The amount of the reduction for residential real property meeting the conditions set forth in subparagraph (2) of subsection (c) shall be calculated as follows:
        (1) for the first, second, and third taxable year after the residential real property is
    
placed in service, the residential real property is entitled to a reduction in its assessed value in an amount equal to the difference between the assessed value in the year for which the incentive is sought and the assessed value for the residential real property in the base year;
        (2) for the fourth, fifth, and sixth taxable year after the residential real property is
    
placed in service, the property is entitled to a reduction in its assessed value in an amount equal to 80% of the difference between the assessed value in the year for which the incentive is sought and the assessed value for the residential real property in the base year;
        (3) for the seventh, eighth, and ninth taxable year after the property is placed in
    
service, the residential real property is entitled to a reduction in its assessed value in an amount equal to 60% of the difference between the assessed value in the year for which the incentive is sought and the assessed value for the residential real property in the base year;
        (4) for the tenth, eleventh, and twelfth taxable year after the residential real
    
property is placed in service, the residential real property is entitled to a reduction in its assessed value in an amount equal to 40% of the difference between the assessed value in the year for which the incentive is sought and the assessed value for the residential real property in the base year; and
        (5) for the thirteenth through the thirtieth taxable year after the residential real
    
property is placed in service, the residential real property is entitled to a reduction in its assessed value in an amount equal to 20% of the difference between the assessed value in the year for which the incentive is sought and the assessed value for the residential real property in the base year.

            (A) The owner is eligible to apply for the reduced valuation conferred by this
        
Section beginning in the first assessment year after the effective date of this amendatory Act of the 102nd General Assembly through December 31, 2027.

However, the initial 10-year eligibility period or 30-year eligibility period, depending on the applicable program, shall be reduced by the number of years between the placed in service date and the date the owner first receives this reduced valuation.
            (F) The owner may apply for the reduced valuation within 2 years after the newly

    "Maximum rent" means the maximum regular rent for 60% of the area median income for the geographic area in which the multifamily building is located for multifamily programs as determined by the United States Department of Housing and Urban Development and published annually by the Illinois Housing Development Authority. To be eligible for the reduced valuation defined in this Section, maximum rents are to be consistent with the Illinois Housing Development Authority's rules; or if the owner is leasing an affordable unit to a household with an income at or below the maximum income limit who is participating in qualifying income-based rental subsidy program, "maximum rent" means the maximum rents allowable under the guidelines of the qualifying income-based rental subsidy program. A property may be deemed to have satisfied the maximum rent with a weighted average if municipal, state, or federal laws, ordinances, rules, or regulations requires the use of a weighted average of no more than 60% of area median income for that property.
    "Qualifying income-based rental subsidy program" means a Housing Choice Voucher issued by a housing authority under Section 8 of the United States Housing Act of 1937, a tenant voucher converted to a project-based voucher by a housing authority or any other program administered or funded by a housing authority, the Illinois Housing Development Authority, another State agency, a federal agency, or a unit of local government where participation is limited to households with incomes at or below the maximum income limits as defined in this Section and the tenants' portion of the rent payment is based on a percentage of their income or a flat amount that does not exceed the maximum rent as defined in this Section.
