Illinois Compiled Statutes

Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

35 ILCS 200/9-270

    (35 ILCS 200/9-270)
    Sec. 9-270. Omitted property; limitations on assessment. A charge for tax and interest for previous years, as provided in Sections 9-265 or 14-40, shall not be made against any property for years prior to the date of ownership of the person owning the property at the time the liability for the omitted tax was first ascertained. Ownership as used in this section shall be held to refer to bona fide legal and equitable titles or interests acquired for value and without notice of the tax, as may appear by deed, deed of trust, mortgage, certificate of purchase or sale, or other form of contract. No charge for tax of previous years, as provided in Section 9-265, shall be made against any property if (1) the assessor failed to notify the board of review of an omitted assessment in accordance with subsection (a-1) of Section 9-260; (2) the property was last assessed as unimproved, the owner of the property gave notice of subsequent improvements and requested a reassessment as required by Section 9-180, and reassessment of the property was not made within the 16 month period immediately following the receipt of that notice; (3) the owner of the property gave notice as required by Section 9-265; (4) the assessor received a building permit for the property evidencing that new construction had occurred or was occurring on the property but failed to list the improvement on the tax rolls; (5) the assessor received a plat map, plat of survey, ALTA survey, mortgage survey, or other similar document containing the omitted property but failed to list the improvement on the tax rolls; (6) the assessor received a real estate transfer declaration indicating a sale from an exempt property owner to a non-exempt property owner but failed to list the property on the tax rolls; or (7) the property was the subject of an assessment appeal before the assessor or the board of review that had included the intended omitted property as part of the assessment appeal and provided evidence of its market value. The owner of property, if known, assessed under this and the preceding section shall be notified by the county assessor, board of review or Department, as the case may require.

35 ILCS 200/9-275

    (35 ILCS 200/9-275)
    Sec. 9-275. Erroneous homestead exemptions.
    (a) For purposes of this Section:
    "Erroneous homestead exemption" means a homestead exemption that was granted for real property in a taxable year if the property was not eligible for that exemption in that taxable year. If the taxpayer receives an erroneous homestead exemption under a single Section of this Code for the same property in multiple years, that exemption is considered a single erroneous homestead exemption for purposes of this Section. However, if the taxpayer receives erroneous homestead exemptions under multiple Sections of this Code for the same property, or if the taxpayer receives erroneous homestead exemptions under the same Section of this Code for multiple properties, then each of those exemptions is considered a separate erroneous homestead exemption for purposes of this Section.
    "Homestead exemption" means an exemption under Section 15-165 (veterans with disabilities), 15-167 (returning veterans), 15-168 (persons with disabilities), 15-169 (standard homestead for veterans with disabilities), 15-170 (senior citizens), 15-172 (low-income senior citizens assessment freeze), 15-175 (general homestead), 15-176 (alternative general homestead), or 15-177 (long-time occupant).
    "Erroneous exemption principal amount" means the total difference between the property taxes actually billed to a property index number and the amount of property taxes that would have been billed but for the erroneous exemption or exemptions.
    "Taxpayer" means the property owner or leasehold owner that erroneously received a homestead exemption upon property.
    (b) Notwithstanding any other provision of law, in counties with 3,000,000 or more inhabitants, the chief county assessment officer shall include the following information with each assessment notice sent in a general assessment year: (1) a list of each homestead exemption available under Article 15 of this Code and a description of the eligibility criteria for that exemption, including the number of assessment years of automatic renewal remaining on a current senior citizens homestead exemption if such an exemption has been applied to the property; (2) a list of each homestead exemption applied to the property in the current assessment year; (3) information regarding penalties and interest that may be incurred under this Section if the taxpayer received an erroneous homestead exemption in a previous taxable year; and (4) notice of the 60-day grace period available under this subsection. If, within 60 days after receiving his or her assessment notice, the taxpayer notifies the chief county assessment officer that he or she received an erroneous homestead exemption in a previous taxable year, and if the taxpayer pays the erroneous exemption principal amount, plus interest as provided in subsection (f), then the taxpayer shall not be liable for the penalties provided in subsection (f) with respect to that exemption.
    (c) In counties with 3,000,000 or more inhabitants, when the chief county assessment officer determines that one or more erroneous homestead exemptions was applied to the property, the erroneous exemption principal amount, together with all applicable interest and penalties as provided in subsections (f) and (j), shall constitute a lien in the name of the People of Cook County on the property receiving the erroneous homestead exemption. Upon becoming aware of the existence of one or more erroneous homestead exemptions, the chief county assessment officer shall cause to be served, by both regular mail and certified mail, a notice of discovery as set forth in subsection (c-5). The chief county assessment officer in a county with 3,000,000 or more inhabitants may cause a lien to be recorded against property that (1) is located in the county and (2) received one or more erroneous homestead exemptions if, upon determination of the chief county assessment officer, the taxpayer received: (A) one or 2 erroneous homestead exemptions for real property, including at least one erroneous homestead exemption granted for the property against which the lien is sought, during any of the 3 collection years immediately prior to the current collection year in which the notice of discovery is served; or (B) 3 or more erroneous homestead exemptions for real property, including at least one erroneous homestead exemption granted for the property against which the lien is sought, during any of the 6 collection years immediately prior to the current collection year in which the notice of discovery is served. Prior to recording the lien against the property, the chief county assessment officer shall cause to be served, by both regular mail and certified mail, return receipt requested, on the person to whom the most recent tax bill was mailed and the owner of record, a notice of intent to record a lien against the property. The chief county assessment officer shall cause the notice of intent to record a lien to be served within 3 years from the date on which the notice of discovery was served.
    (c-5) The notice of discovery described in subsection (c) shall: (1) identify, by property index number, the property for which the chief county assessment officer has knowledge indicating the existence of an erroneous homestead exemption; (2) set forth the taxpayer's liability for principal, interest, penalties, and administrative costs including, but not limited to, recording fees described in subsection (f); (3) inform the taxpayer that he or she will be served with a notice of intent to record a lien within 3 years from the date of service of the notice of discovery; (4) inform the taxpayer that he or she may pay the outstanding amount, plus interest, penalties, and administrative costs at any time prior to being served with the notice of intent to record a lien or within 30 days after the notice of intent to record a lien is served; and (5) inform the taxpayer that, if the taxpayer provided notice to the chief county assessment officer as provided in subsection (d-1) of Section 15-175 of this Code, upon submission by the taxpayer of evidence of timely notice and receipt thereof by the chief county assessment officer, the chief county assessment officer will withdraw the notice of discovery and reissue a notice of discovery in compliance with this Section in which the taxpayer is not liable for interest and penalties for the current tax year in which the notice was received.
    For the purposes of this subsection (c-5):
    "Collection year" means the year in which the first and second installment of the current tax year is billed.
    "Current tax year" means the year prior to the collection year.
    (d) The notice of intent to record a lien described in subsection (c) shall: (1) identify, by property index number, the property against which the lien is being sought; (2) identify each specific homestead exemption that was erroneously granted and the year or years in which each exemption was granted; (3) set forth the erroneous exemption principal amount due and the interest amount and any penalty and administrative costs due; (4) inform the taxpayer that he or she may request a hearing within 30 days after service and may appeal the hearing officer's ruling to the circuit court; (5) inform the taxpayer that he or she may pay the erroneous exemption principal amount, plus interest and penalties, within 30 days after service; and (6) inform the taxpayer that, if the lien is recorded against the property, the amount of the lien will be adjusted to include the applicable recording fee and that fees for recording a release of the lien shall be incurred by the taxpayer. A lien shall not be filed pursuant to this Section if the taxpayer pays the erroneous exemption principal amount, plus penalties and interest, within 30 days of service of the notice of intent to record a lien.
    (e) The notice of intent to record a lien shall also include a form that the taxpayer may return to the chief county assessment officer to request a hearing. The taxpayer may request a hearing by returning the form within 30 days after service. The hearing shall be held within 90 days after the taxpayer is served. The chief county assessment officer shall promulgate rules of service and procedure for the hearing. The chief county assessment officer must generally follow rules of evidence and practices that prevail in the county circuit courts, but, because of the nature of these proceedings, the chief county assessment officer is not bound by those rules in all particulars. The chief county assessment officer shall appoint a hearing officer to oversee the hearing. The taxpayer shall be allowed to present evidence to the hearing officer at the hearing. After taking into consideration all the relevant testimony and evidence, the hearing officer shall make an administrative decision on whether the taxpayer was erroneously granted a homestead exemption for the taxable year in question. The taxpayer may appeal the hearing officer's ruling to the circuit court of the county where the property is located as a final administrative decision under the Administrative Review Law.
    (f) A lien against the property imposed under this Section shall be filed with the county recorder of deeds, but may not be filed sooner than 60 days after the notice of intent to record a lien was delivered to the taxpayer if the taxpayer does not request a hearing, or until the conclusion of the hearing and all appeals if the taxpayer does request a hearing. If a lien is filed pursuant to this Section and the taxpayer received one or 2 erroneous homestead exemptions during any of the 3 collection years immediately prior to the current collection year in which the notice of discovery is served, then the erroneous exemption principal amount, plus 10% interest per annum or portion thereof from the date the erroneous exemption principal amount would have become due if properly included in the tax bill, shall be charged against the property by the chief county assessment officer. However, if a lien is filed pursuant to this Section and the taxpayer received 3 or more erroneous homestead exemptions during any of the 6 collection years immediately prior to the current collection year in which the notice of discovery is served, the erroneous exemption principal amount, plus a penalty of 50% of the total amount of the erroneous exemption principal amount for that property and 10% interest per annum or portion thereof from the date the erroneous exemption principal amount would have become due if properly included in the tax bill, shall be charged against the property by the chief county assessment officer. If a lien is filed pursuant to this Section, the taxpayer shall not be liable for interest that accrues between the date the notice of discovery is served and the date the lien is filed. Before recording the lien with the county recorder of deeds, the chief county assessment officer shall adjust the amount of the lien to add administrative costs, including but not limited to the applicable recording fee, to the total lien amount.
    (g) If a person received an erroneous homestead exemption under Section 15-170 and: (1) the person was the spouse, child, grandchild, brother, sister, niece, or nephew of the previous taxpayer; and (2) the person received the property by bequest or inheritance; then the person is not liable for the penalties imposed under this Section for any year or years during which the chief county assessment officer did not require an annual application for the exemption or, in a county with 3,000,000 or more inhabitants, an application for renewal of a multi-year exemption pursuant to subsection (i) of Section 15-170, as the case may be. However, that person is responsible for any interest owed under subsection (f).
    (h) If the erroneous homestead exemption was granted as a result of a clerical error or omission on the part of the chief county assessment officer, and if the taxpayer has paid the tax bills as received for the year in which the error occurred, then the interest and penalties authorized by this Section with respect to that homestead exemption shall not be chargeable to the taxpayer. However, nothing in this Section shall prevent the collection of the erroneous exemption principal amount due and owing.
    (i) A lien under this Section is not valid as to (1) any bona fide purchaser for value without notice of the erroneous homestead exemption whose rights in and to the underlying parcel arose after the erroneous homestead exemption was granted but before the filing of the notice of lien; or (2) any mortgagee, judgment creditor, or other lienor whose rights in and to the underlying parcel arose before the filing of the notice of lien. A title insurance policy for the property that is issued by a title company licensed to do business in the State showing that the property is free and clear of any liens imposed under this Section shall be prima facie evidence that the taxpayer is without notice of the erroneous homestead exemption. Nothing in this Section shall be deemed to impair the rights of subsequent creditors and subsequent purchasers under Section 30 of the Conveyances Act.
    (j) When a lien is filed against the property pursuant to this Section, the chief county assessment officer shall mail a copy of the lien to the person to whom the most recent tax bill was mailed and to the owner of record, and the outstanding liability created by such a lien is due and payable within 30 days after the mailing of the lien by the chief county assessment officer. This liability is deemed delinquent and shall bear interest beginning on the day after the due date at a rate of 1.5% per month or portion thereof. Payment shall be made to the county treasurer. Upon receipt of the full amount due, as determined by the chief county assessment officer, the county treasurer shall distribute the amount paid as provided in subsection (k). Upon presentment by the taxpayer to the chief county assessment officer of proof of payment of the total liability, the chief county assessment officer shall provide in reasonable form a release of the lien. The release of the lien provided shall clearly inform the taxpayer that it is the responsibility of the taxpayer to record the lien release form with the county recorder of deeds and to pay any applicable recording fees.
    (k) The county treasurer shall pay collected erroneous exemption principal amounts, pro rata, to the taxing districts, or their legal successors, that levied upon the subject property in the taxable year or years for which the erroneous homestead exemptions were granted, except as set forth in this Section. The county treasurer shall deposit collected penalties and interest into a special fund established by the county treasurer to offset the costs of administration of the provisions of this Section by the chief county assessment officer's office, as appropriated by the county board. If the costs of administration of this Section exceed the amount of interest and penalties collected in the special fund, the chief county assessor shall be reimbursed by each taxing district or their legal successors for those costs. Such costs shall be paid out of the funds collected by the county treasurer on behalf of each taxing district pursuant to this Section.
    (l) The chief county assessment officer in a county with 3,000,000 or more inhabitants shall establish an amnesty period for all taxpayers owing any tax due to an erroneous homestead exemption granted in a tax year prior to the 2013 tax year. The amnesty period shall begin on the effective date of this amendatory Act of the 98th General Assembly and shall run through December 31, 2013. If, during the amnesty period, the taxpayer pays the entire arrearage of taxes due for tax years prior to 2013, the county clerk shall abate and not seek to collect any interest or penalties that may be applicable and shall not seek civil or criminal prosecution for any taxpayer for tax years prior to 2013. Failure to pay all such taxes due during the amnesty period established under this Section shall invalidate the amnesty period for that taxpayer.
    The chief county assessment officer in a county with 3,000,000 or more inhabitants shall (i) mail notice of the amnesty period with the tax bills for the second installment of taxes for the 2012 assessment year and (ii) as soon as possible after the effective date of this amendatory Act of the 98th General Assembly, publish notice of the amnesty period in a newspaper of general circulation in the county. Notices shall include information on the amnesty period, its purpose, and the method by which to make payment.
    Taxpayers who are a party to any criminal investigation or to any civil or criminal litigation that is pending in any circuit court or appellate court, or in the Supreme Court of this State, for nonpayment, delinquency, or fraud in relation to any property tax imposed by any taxing district located in the State on the effective date of this amendatory Act of the 98th General Assembly may not take advantage of the amnesty period.
    A taxpayer who has claimed 3 or more homestead exemptions in error shall not be eligible for the amnesty period established under this subsection.
    (m) Notwithstanding any other provision of law, for taxable years 2019 through 2023, in counties with 3,000,000 or more inhabitants, the chief county assessment officer shall, if he or she learns that a taxpayer who has been granted a senior citizens homestead exemption has died during the period to which the exemption applies, send a notice to the address on record for the owner of record of the property notifying the owner that the exemption will be terminated unless, within 90 days after the notice is sent, the chief county assessment officer is provided with a basis to continue the exemption. The notice shall be sent by first-class mail, in an envelope that bears on its front, in boldface red lettering that is at least one inch in size, the words "Notice of Exemption Termination"; however, if the taxpayer elects to receive the notice by email and provides an email address, then the notice shall be sent by email.

35 ILCS 200/10-5

    (35 ILCS 200/10-5)
    Sec. 10-5. Solar energy systems; definitions. It is the policy of this State that the use of solar energy systems should be encouraged because they conserve nonrenewable resources, reduce pollution and promote the health and well-being of the people of this State, and should be valued in relation to these benefits.
    (a) "Solar energy" means radiant energy received from the sun at wave lengths suitable for heat transfer, photosynthetic use, or photovoltaic use.
    (b) "Solar collector" means
        (1) An assembly, structure, or design, including
    
passive elements, used for gathering, concentrating, or absorbing direct and indirect solar energy, specially designed for holding a substantial amount of useful thermal energy and to transfer that energy to a gas, solid, or liquid or to use that energy directly; or
        (2) A mechanism that absorbs solar energy and
    
converts it into electricity; or
        (3) A mechanism or process used for gathering solar
    
energy through wind or thermal gradients; or
        (4) A component used to transfer thermal energy to a
    
gas, solid, or liquid, or to convert it into electricity.
    (c) "Solar storage mechanism" means equipment or elements (such as piping and transfer mechanisms, containers, heat exchangers, or controls thereof, and gases, solids, liquids, or combinations thereof) that are utilized for storing solar energy, gathered by a solar collector, for subsequent use.
    (d) "Solar energy system" means
        (1)(A) A complete assembly, structure, or design of
    
solar collector, or a solar storage mechanism, which uses solar energy for generating electricity that is primarily consumed on the property on which the solar energy system resides, or for heating or cooling gases, solids, liquids, or other materials for the primary benefit of the property on which the solar energy system resides;
        (B) The design, materials, or elements of a system
    
and its maintenance, operation, and labor components, and the necessary components, if any, of supplemental conventional energy systems designed or constructed to interface with a solar energy system;
        (C) Any legal, financial, or institutional orders,
    
certificates, or mechanisms, including easements, leases, and agreements, required to ensure continued access to solar energy, its source, or its use in a solar energy system, and including monitoring and educational elements of a demonstration project; or
        (D) Photovoltaic electricity generation systems
    
subject to power purchase agreements or leases for solar energy between a third-party owner, an operator, or both, and an end user of electricity, where such systems are located on the end user of electricity's side of the electric meter and which primarily are used to offset the electricity load of the end user behind whose electric meter the system is connected. A system primarily is used to offset the electricity load of the end user of electricity if the system is estimated to produce 110% or fewer kilowatt-hours of electricity than consumed by the end user of electricity at such meter in the last 12 full months prior to the system being placed in service.
        (2) "Solar energy system" does not include:
            (A) Distribution equipment that is equally usable
        
in a conventional energy system except for those components of the equipment that are necessary for meeting the requirements of efficient solar energy utilization;
            (B) Components of a solar energy system that
        
serve structural, insulating, protective, shading, aesthetic, or other non-solar energy utilization purposes, as defined in the regulations of the Department of Commerce and Economic Opportunity; or
            (C) A commercial solar energy system, as defined
        
by this Code, in counties with fewer than 3,000,000 inhabitants.
        (3) The solar energy system shall conform to the
    
standards for those systems established by regulation of the Department of Commerce and Economic Opportunity.

35 ILCS 200/10-10

    (35 ILCS 200/10-10)
    Sec. 10-10. Valuation of solar energy systems. When a solar energy system has been installed in improvements on any property, the owner of that property is entitled to claim, by filing with the chief county assessment officer, an alternate valuation of those improvements. When a claim for alternate valuation is filed, the chief county assessment officer shall ascertain the value of the improvements as if equipped with a conventional heating or cooling system and the value of the improvements as equipped with the solar energy system. So long as the solar energy system is used in total or part as the means of utilizing solar energy improvements, the alternate valuation computed as the lesser of the two values ascertained under this paragraph shall be applied. When the solar energy system so valued ceases to be used as the means of heating or cooling those improvements, the owner of that property shall within 30 days notify the chief county assessment officer in writing by certified mail.

    (35 ILCS 200/10-20)
    Sec. 10-20. Repairs and maintenance of residential property. Maintenance and repairs to residential property owned and used exclusively for a residential purpose shall not increase the assessed valuation of the property. For purposes of this Section, work shall be deemed repair and maintenance when it (1) does not increase the square footage of improvements and does not materially alter the existing character and condition of the structure but is limited to work performed to prolong the life of the existing improvements or to keep the existing improvements in a well maintained condition; and (2) employs materials, such as those used for roofing or siding, whose value is not greater than the replacement value of the materials being replaced. Maintenance and repairs, as those terms are used in this Section, to property that enhance the overall exterior and interior appearance and quality of a residence by restoring it from a state of disrepair to a standard state of repair do not "materially alter the existing character and condition" of the residence.

    (35 ILCS 200/10-25)
    Sec. 10-25. Model homes, townhomes, and condominium units. If the construction of a single family dwelling is completed after December 29, 1986 or the construction of a single family townhome or condominium unit is completed after the effective date of this amendatory Act of 1994, and that dwelling, townhome, or condominium unit is not occupied as a dwelling but is used as a display or demonstration model home, townhome or condominium unit for prospective buyers of the dwelling or of similar homes, townhomes, or condominium units to be built on other property, the assessed value of the property on which the dwelling, townhome, or condominium was constructed shall be the same as the assessed value of the property prior to construction and prior to any change in the zoning classification of the property prior to construction of the dwelling, townhome or condominium unit. The application of this Section shall not be affected if the display or demonstration model home, townhome or condominium unit contains home furnishings, appliances, offices, and office equipment to further sales activities. This Section shall not be applicable if the dwelling, townhome, or condominium unit is occupied as a dwelling or the property on which the dwelling, townhome, or condominium unit is situated is sold or leased for use other than as a display or demonstration model home, townhome, or condominium unit. No property shall be eligible for calculation of its assessed value under this Section for more than a 10-year period. If the dwelling, townhome, or condominium unit becomes ineligible for the alternate valuation, the owner shall within 60 days file with the chief county assessment officer a certificate giving notice of such ineligibility.
    For the purposes of this Section, no corporation, individual, sole proprietor or partnership may have more than a total of 3 model homes, townhomes, or condominium units at the same time within a 3 mile radius. The center point of each radius shall be the display or demonstration model that has been used as such for the longest period of time. The person liable for taxes on property eligible for assessment as provided in this Section shall file a verified application with the chief county assessment officer on or before (i) April 30 of each assessment year for which that assessment is desired in counties with a population of 3,000,000 or more and (ii) December 31 of each assessment year for which that assessment is desired in all other counties. Failure to make a timely filing in any assessment year constitutes a waiver of the right to benefit for that assessment year.

    (35 ILCS 200/10-30)
    Sec. 10-30. Subdivisions; counties of less than 3,000,000.
    (a) In counties with less than 3,000,000 inhabitants, the platting and subdivision of property into separate lots and the development of the subdivided property with streets, sidewalks, curbs, gutters, sewer, water and utility lines shall not increase the assessed valuation of all or any part of the property, if:
        (1) The property is platted and subdivided in
    
accordance with the Plat Act;
        (2) The platting occurs after January 1, 1978;
        (3) At the time of platting the property is in excess
    
of 5 acres; and
        (4) At the time of platting the property is vacant or
    
used as a farm as defined in Section 1-60.
    (b) Except as provided in subsection (c) of this Section, the assessed valuation of property so platted and subdivided shall be determined each year based on the estimated price the property would bring at a fair voluntary sale for use by the buyer for the same purposes for which the property was used when last assessed prior to its platting.
    (c) Upon completion of a habitable structure on any lot of subdivided property, or upon the use of any lot, either alone or in conjunction with any contiguous property, for any business, commercial or residential purpose, or upon the initial sale of any platted lot, including a platted lot which is vacant: (i) the provisions of subsection (b) of this Section shall no longer apply in determining the assessed valuation of the lot, (ii) each lot shall be assessed without regard to any provision of this Section, and (iii) the assessed valuation of the remaining property, when next determined, shall be reduced proportionately to reflect the exclusion of the property that no longer qualifies for valuation under this Section. Holding or offering a platted lot for initial sale shall not constitute a use of the lot for business, commercial or residential purposes unless a habitable structure is situated on the lot or unless the lot is otherwise used for a business, commercial or residential purpose.
    (d) This Section applies before the effective date of this amendatory Act of the 96th General Assembly and then applies again beginning January 1, 2012.

    (a) In counties with less than 3,000,000 inhabitants, the platting and subdivision of property into separate lots and the development of the subdivided property with streets, sidewalks, curbs, gutters, sewer, water and utility lines shall not increase the assessed valuation of all or any part of the property, if:
        (1) The property is platted and subdivided in
    
accordance with the Plat Act;
        (2) The platting occurs after January 1, 1978;
        (3) At the time of platting the property is in excess
    
of 5 acres; and
        (4) At the time of platting or replatting the
    
property is vacant or used as a farm as defined in Section 1-60.
    (b) Except as provided in subsection (c) of this Section, the assessed valuation of property so platted and subdivided shall be determined based on the assessed value assigned to the property when last assessed prior to its last transfer or conveyance. An initial sale of any platted lot, including a lot that is vacant, or a transfer to a holder of a mortgage, as defined in Section 15-1207 of the Code of Civil Procedure, pursuant to a mortgage foreclosure proceeding or pursuant to a transfer in lieu of foreclosure, does not disqualify that lot from the provisions of this subsection (b).
    (c) Upon completion of a habitable structure on any lot of subdivided property, or upon the use of any lot, either alone or in conjunction with any contiguous property, for any business, commercial or residential purpose: (i) the provisions of subsection (b) of this Section shall no longer apply in determining the assessed valuation of the lot, (ii) each lot shall be assessed without regard to any provision of this Section, and (iii) the assessed valuation of the remaining property, when next determined, shall be reduced proportionately to reflect the exclusion of the property that no longer qualifies for valuation under this Section. Holding or offering a platted lot for initial sale shall not constitute a use of the lot for business, commercial or residential purposes unless a habitable structure is situated on the lot or unless the lot is otherwise used for a business, commercial or residential purpose. The replatting of a subdivision or portion of a subdivision does not disqualify the replatted lots from the provisions of subsection (b).
    (d) This Section applies on and after the effective date of this amendatory Act of the 96th General Assembly and through December 31, 2011.

    Sec. 10-35. Subdivision common areas.
    (a) Residential property which is part of a development, but which is individually owned and ownership of which includes the right, by easement, covenant, deed or other interest in property, to the use of any common area for recreational or similar residential purposes shall be assessed at a value which includes the proportional share of the value of that common area or areas.
    Property is used as a "common area or areas" under this Section if it is a lot, parcel, or area, the beneficial use and enjoyment of which is reserved in whole as an appurtenance to the separately owned lots, parcels, or areas within the planned development.
    The common area or areas which are used for recreational or similar residential purposes and which are assessed to a separate owner and are located on separately identified parcels, shall be listed for assessment purposes at $1 per year.
    (b) In counties with 3,000,000 or more inhabitants, any person desiring to establish or to reestablish an assessment of $1 for any parcel on the grounds of common area status under this Section shall submit an application for the assessment to the assessor. The application shall be submitted at the time within which other applications for revisions of assessment may be made under Section 14-35 by taxpayers in the township where the parcel is located, and shall be in the form and accompanied by documentation, as the assessor may require.
    (b-5) In counties with fewer than 3,000,000 inhabitants, the chief county assessment officer may require any person desiring to establish or reestablish an assessment of $1 for any parcel on the grounds of common area status under this Section to submit an application for the assessment to the chief county assessment officer. The application shall be submitted no later than June 30 of the year for which the assessment is sought and shall be in the form and accompanied by documentation that the chief county assessment officer requires.
    (c) If a $1 assessment is established pursuant to the application it may be maintained from year to year so long as the ownership or use of the parcel has not changed. When any change in ownership, use or other relevant fact occurs it shall be the duty of the new owner in cases of change in ownership, or of the current owner in all other cases, to notify the assessor in writing within 30 days of the change. The notice shall be sent by certified mail, return receipt requested, and shall include the name and address of the taxpayer, the legal description of the property, and the permanent index number of the property where such number exists. If the failure to give such notification results in the assessor continuing to assess the property at $1 in subsequent years in error, the property shall be considered omitted property under Section 9-265. Nothing in this Section shall be construed to limit the assessor's authority to annually revise assessments subject to this Section under the procedures of Section 9-85.
    (d) No objection shall be made to the denial of an assessment of $1 under this Section in any court except under Sections 21-175 and 23-5. No person may object to or otherwise challenge the failure of any parcel to receive an assessment of $1 under this Section in any proceeding in any court unless an application for the $1 assessment was made under subsections (b) and (b-5) of this Section.

If there has been such a change, the nature of this change shall be stated. Failure to file such an affidavit shall, in the discretion of the chief county assessment officer, constitute cause to revoke the certificate of rehabilitation.

All provisions relating to the assessment and taxation of property, shall apply to those bridges. The assessor shall give in his or her description the quarter section of property, section of property, township and range in which the bridge is located or terminates in this State, together with the metes and bounds of the ground occupied by the bridge and the approaches to it, from the end on the Illinois shore to the center of the main channel of the stream crossed by the bridge. To obtain the description, the assessor may employ a competent surveyor, and the expense of making the survey and description shall be charged as a tax against the property by the county clerk, on the certificate of the surveyor. One survey of any bridge and approaches made under this Code, shall be deemed sufficient for the purpose of subsequent assessment of the bridge or approaches.
    In default of the payment of any tax assessed against any bridge company, the bridge structure and its approaches that are located within this State, together with the land on which they are located, as described by the assessor, and the franchise belonging thereto, shall be sold for the tax at the same time and in the same manner as other property in the county is sold for delinquent tax. Any county, city, town, school district or other municipal corporation, interested in the collection of the tax levied upon the bridge, may become the purchaser at the sale, or at any sale of the property under judgment recovered upon, or to enforce the collection of the tax; and if the property so sold is not redeemed, may acquire, hold, sell and dispose of the title.

    Sec. 10-180. Developed coal. Developed coal shall be assessed at 33 1/3% of the developed coal reserve economic value determined as follows:
    Developed Coal Reserve Economic Value equals the present value of the anticipated net income from the property during the life used to determine the developed coal.
    (a) The interest rate to be used for determining present value shall be the arithmetic average prime interest rate quoted by the 4 largest United States banks as measured by total assets located within the Chicago metropolitan statistical area as defined by the United States Department of Commerce as of the current assessment date and the 2 preceding assessment dates, plus 3%.
    (b) Net income means 4% of the average spot market price for Illinois coal as published in a recognized publication prescribed by the Department, as of the current assessment date and the 2 preceding assessment dates, multiplied by the number of recoverable tons per acre.
    (c) Recoverable coal tons per acre equals 1,742 tons per foot acre multiplied by seam thickness, and then multiplied by the recovery ratio.
    (d) Coal seam thickness means the average thickness of the coal seam or seams where coal is initially extracted.
    (e) Recovery ratio means the lesser of 80% for coal extracted by surface mining methods and 50% for coal extracted by underground mining methods or the actual historical recovery ratio for the mining operation.

    (35 ILCS 200/10-230)
    Sec. 10-230. Creation of task force; 1997 through 1999 property assessments of certain utility property.
    (a) This Section establishes an Electric Utility Property Assessment Task Force to advise the General Assembly with respect to the possible impact of the Electric Service Customer Choice and Rate Relief Law of 1997 on the valuation of the real property component of electric generating stations owned by electric utilities and, therefore, on the taxing districts in this State in which electric generating stations are located.
    (b) There shall be established and appointed in accordance with this Section an Electric Utility Property Assessment Task Force. Such Task Force shall be chaired by the President of the Taxpayers' Federation of Illinois, who shall be a non-voting member of the Task Force. The Task Force shall be composed of 10 voting members, 6 of whom shall be representatives of taxing districts in which electric generating stations are located and 4 of whom shall be representatives of electric utilities in this State, at least one of whom shall be from an electric utility serving over 1,000,000 retail customers in this State and at least one of whom shall be from an electric utility serving over 500,000 but less than 1,000,000 retail customers in this State.
    (c) The voting members of this Task Force shall be appointed as follows: (i) 3 of the voting members, one of whom shall be from an electric utility, shall be appointed by the President of the Senate; (ii) 3 of the voting members, one of whom shall be from an electric utility, shall be appointed by the Speaker of the House of Representatives; (iii) 2 of the voting members, one of whom shall be from an electric utility, shall be appointed by the Minority Leader of the Senate; and (iv) 2 of the voting members, one of whom shall be from an electric utility, shall be appointed by the Minority Leader of the House of Representatives. Such appointments shall be made within 30 days after the effective date of this amendatory Act of 1997. Members of the Task Force shall receive no compensation for their services but shall be entitled to reimbursement of reasonable expenses incurred while performing their duties.
    (d) The Task Force shall submit a report to the General Assembly by January 1, 1999 which shall: (i) analyze whether, and to what extent, taxing districts throughout this State will experience significant sustained erosions of their property tax bases and property tax revenues as a result of the restructuring of the electric industry in this State; and (ii) make recommendations for legislative changes to address any such impacts.
    (e) Beginning with the 1997 assessment year through the assessment year of 1999, the fair cash value of any electric power generating plant owned as of November 1, 1997, by an electric utility, as that term is defined in Section 16-102 of the Public Utilities Act, shall be determined using original cost less depreciation of the electric power generating plant. When determining original cost less depreciation, including the original cost less depreciation of all new construction, the rate or rates of depreciation applied shall be the same as the rate or rates in effect November 1, 1997, under the Public Utilities Act and the rules and orders of the Illinois Commerce Commission, irrespective of any change in ownership of the property occurring after the effective date of the provisions of the Electric Service Customer Choice and Rate Relief Law of 1997. Nothing in this subsection shall be construed to affect the classification of property as real or personal. Determinations of original cost less depreciation for purposes of this subsection shall be made without regard for the use of any accelerated cost recovery method including accelerated depreciation, accelerated amortization or other capital recovery methods, or reductions to original cost of an electric power generating plant made as a result of the provisions of Senate Amendment No. 2 to House Bill 362, enacted by the 90th General Assembly.

It is the policy of this State that low-income housing projects developed under Section 515 of the federal Housing Act or that qualify for the low-income housing tax credit under Section 42 of the Internal Revenue Code shall be valued at 33 and one-third percent of the fair market value of their economic productivity to the owners of the projects to help insure that their valuation for property taxation does not result in taxes so high that rent levels must be raised to cover this project expense, which can cause excess vacancies, project loan defaults, and eventual loss of rental housing facilities for those most in need of them, low-income families and the elderly. It is the intent of this State that the valuation required by this Division is the closest representation of cash value required by law and is the method established as proper and fair.

The capitalization rate for items (i) and (ii) shall be one that reflects the prevailing cost of capital for other types of similarly encumbered Section 42 properties in the geographic market in which the low-income housing project is located.
    All low-income housing projects that seek to be assessed in accordance with the provisions of this Section shall certify to the appropriate local assessment officer that the owner or owners qualify for the Low-Income Housing Tax Credit under Section 42 of the Internal Revenue Code for the property, in a form prescribed by that assessment officer.

    (a) This Division may be cited as the Conservation Stewardship Law.
    (b) The General Assembly finds that it is in the best interest of this State to maintain, preserve, conserve, and manage unimproved land to assure the protection of these limited and unique environmental resources for the economic and social well-being of the State and its citizens.
    The General Assembly further finds that, to maximize voluntary taxpayer participation in conservation programs, conservation should be recognized as a legitimate land use and taxpayers should have a full range of incentive programs from which to choose.
    Therefore, the General Assembly declares that it is in the public interest to prevent the forced conversion of unimproved land to more intensive uses as a result of economic pressures caused by the property tax system at values incompatible with their preservation and management as unimproved land, and that a program should be designed to permit the continued availability of this land for these purposes.
    The General Assembly further declares that the following provisions are intended to allow for the conservation, management, and assessment of unimproved land generally suitable for the perpetual growth and preservation of such land in this State.
