A BILL FOR
HB3466 LRB104 09604 HLH 19669 b
AN ACT concerning revenue.
Be it enacted by the People of the State of Illinois,
represented in the General Assembly:
Section 5. The Property Tax Code is amended by changing
Section 15-178 as follows:
(35 ILCS 200/15-178)
Sec. 15-178. Affordable housing special assessment
programs; reduction 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

HB3466 - 2 - LRB104 09604 HLH 19669 b
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
substantially rehabilitated 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. A county opting out shall not disqualify or shorten the
maximum eligibility periods for any property approved to
receive a reduced valuation prior to the county opting out.
The special assessment programs available under this Section
shall be available to all qualifying residential real property
regardless of whether or not the property has or is currently
receiving any other public financing or subsidies or subject
to any regulatory agreements with any public entity, or both.

HB3466 - 3 - LRB104 09604 HLH 19669 b
The changes made to this subsection by this amendatory Act of
the 104th General Assembly are declarative of existing law and
shall not be construed as a new enactment. 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 substantially rehabilitated 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

HB3466 - 4 - LRB104 09604 HLH 19669 b
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 substantially rehabilitated 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 substantially rehabilitated 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

HB3466 - 5 - LRB104 09604 HLH 19669 b
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

HB3466 - 6 - LRB104 09604 HLH 19669 b
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

HB3466 - 7 - LRB104 09604 HLH 19669 b
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.

(B) of paragraph (4) of subsection (d) of this

HB3466 - 12 - LRB104 09604 HLH 19669 b
Section. If an owner is approved for the reduced
valuation conferred by this Section prior to December

(B) Property receiving a reduction outlined in
paragraph (1) of subsection (c) of this Section shall
continue to be eligible for an initial period of up to
10 years if annual certification requirements are met
for each of the 10 years, but shall be extended for up

and transferees who comply with all requirements of
this Section excluding the requirements regarding new
construction or qualifying rehabilitation defined in
subparagraph (D) of paragraph (1) of this subsection
are eligible to apply for renewal on the schedule set
by the initial application.
(E) (Blank). The owner may apply for the reduced
valuation if the residential real property meets all
requirements of this Section and the newly constructed
residential real property or improvements to existing
residential real property were put in service on or
after January 1, 2015. 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 constructed residential
real property or improvements to existing residential
real property are put in service. However, the initial
10-year eligibility period or 30-year eligibility

HB3466 - 14 - LRB104 09604 HLH 19669 b

of the 102nd General Assembly takes effect shall be
deemed automatically eligible for the reduced
valuation defined in paragraph (1) of subsection (c)
of this Section in terms of meeting the criteria for
new construction or substantial rehabilitation for a
specific multifamily building regardless of when the
newly constructed residential real property or
improvements to existing residential real property
were put in service. If a Cook County Class 9 owner had
Class 9 status revoked on or after January 1, 2017 but
can provide documents sufficient to prove that the
revocation was in error or any deficiencies leading to
the revocation have been cured, the chief county
assessment officer may deem the owner to be eligible.
However, owners may not receive both the reduced
valuation under this Section and the reduced valuation
under the Cook County Class 9 program in any single
assessment year. In addition, the number of years
during which an owner has participated in the Class 9

HB3466 - 15 - LRB104 09604 HLH 19669 b
program shall count against the 3 10-year periods of
eligibility for the reduced valuation as defined in
subparagraph (1) of subsection (c) of this Section.
(H) At the completion of the assessment reduction
period described in this Section: the entire parcel
will be assessed as otherwise provided by law.
