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.

65 ILCS 5/Art. 7 Div. 1

 
    (65 ILCS 5/Art. 7 Div. 1 heading)
DIVISION 1. ANNEXATION

65 ILCS 5/7-1-1

    (65 ILCS 5/7-1-1) (from Ch. 24, par. 7-1-1)
    Sec. 7-1-1. Annexation of contiguous territory. Any territory that is not within the corporate limits of any municipality but is contiguous to a municipality may be annexed to the municipality as provided in this Article. For the purposes of this Article any territory to be annexed to a municipality shall be considered to be contiguous to the municipality notwithstanding that the territory is separated from the municipality by a lake, river, or other waterway or the territory is separated from the municipality by a strip parcel, railroad or public utility right-of-way, or former railroad right-of-way that has been converted to a recreational trail, but upon annexation the area included within that strip parcel, right-of-way, or former right-of-way shall not be considered to be annexed to the municipality. For purposes of this Section, "strip parcel" means a separation no wider than 30 feet between the territory to be annexed and the municipal boundary.
    Except in counties with a population of more than 600,000 but less than 3,000,000, territory which is not contiguous to a municipality but is separated therefrom only by a forest preserve district, federal wildlife refuge, open land or open space that is part of an open space program, as defined in Section 115-5 of the Township Code, or conservation area, may be annexed to the municipality pursuant to Section 7-1-7 or 7-1-8, but only if the annexing municipality can show that the forest preserve district, federal wildlife refuge, open land, open space, or conservation area creates an artificial barrier preventing the annexation and that the location of the forest preserve district, federal wildlife refuge, open land, open space, or conservation area property prevents the orderly natural growth of the annexing municipality. Except for parcels of land less than one acre in size, it shall be conclusively presumed that the forest preserve district, federal wildlife refuge, open land, open space, or conservation area does not create an artificial barrier if the property sought to be annexed is bounded on at least 3 sides by (i) one or more other municipalities (other than the municipality seeking annexation through the existing forest preserve district, federal wildlife refuge, open land, open space, or conservation area), (ii) forest preserve district property, federal wildlife refuge, open land, open space, or conservation area, or (iii) a combination of other municipalities and forest preserve district property, federal wildlife refuge property, open land, open space, or conservation area. Except of parcels of land less than one acre in size, it shall also be conclusively presumed that the forest preserve district, federal wildlife refuge, open land, open space, or conservation area does not create an artificial barrier if the municipality seeking annexation is not the closest municipality within the county to the property to be annexed. The territory included within such forest preserve district, federal wildlife refuge, open land, open space, or conservation area shall not be annexed to the municipality nor shall the territory of the forest preserve district, federal wildlife refuge, open land, open space, or conservation area be subject to rights-of-way for access or services between the parts of the municipality separated by the forest preserve district, federal wildlife refuge, open land, open space, or conservation area without the consent of the governing body of the forest preserve district or federal wildlife refuge. Parcels of land less than one acre in size may be annexed to the municipality pursuant to Section 7-1-7 or 7-1-8 if it would be contiguous to the municipality but for the separation therefrom by a forest preserve district, federal wildlife refuge, open land or open space that is part of an open space program, as defined in Section 115-5 of the Township Code, or conservation area. The changes made to this Section by Public Act 91-824 are declaratory of existing law and shall not be construed as a new enactment.
    For the purpose of this Section, "conservation area" means an area dedicated to conservation and owned by a not-for-profit organized under Section 501(c)(3) of the Internal Revenue Code of 1986, or any area owned by a conservation district.
    In counties that are contiguous to the Mississippi River with populations of more than 200,000 but less than 255,000, a municipality that is partially located in territory that is wholly surrounded by the Mississippi River and a canal, connected at both ends to the Mississippi River and located on property owned by the United States of America, may annex noncontiguous territory in the surrounded territory under Sections 7-1-7, 7-1-8, or 7-1-9 if that territory is separated from the municipality by property owned by the United States of America, but that federal property shall not be annexed without the consent of the federal government.
    For the purposes of this Article, any territory to be annexed to a municipality that is located in a county with more than 500,000 inhabitants shall be considered to be contiguous to the municipality if only a river and a national heritage corridor separate the territory from the municipality. Upon annexation, no river or national heritage corridor shall be considered annexed to the municipality.
    When any land proposed to be annexed is part of any Fire Protection District or of any Public Library District and the annexing municipality provides fire protection or a public library, as the case may be, the Trustees of each District shall be notified in writing by certified or registered mail before any court hearing or other action is taken for annexation. The notice shall be served 10 days in advance. An affidavit that service of notice has been had as provided by this Section must be filed with the clerk of the court in which the annexation proceedings are pending or will be instituted or, when no court proceedings are involved, with the recorder for the county where the land is situated. No annexation of that land is effective unless service is had and the affidavit filed as provided in this Section.
    The new boundary shall extend to the far side of any adjacent highway and shall include all of every highway within the area annexed. These highways shall be considered to be annexed even though not included in the legal description set forth in the petition for annexation. When any land proposed to be annexed includes any highway under the jurisdiction of any township, the Township Commissioner of Highways, the Board of Town Trustees, the Township Supervisor, and the Township Clerk shall be notified in writing by certified or registered mail before any court hearing or other action is taken for annexation. In the event that a municipality fails to notify the Township Commissioner of Highways, the Board of Town Trustees, the Township Supervisor, and the Township Clerk of the annexation of an area within the township, the municipality shall reimburse that township for any loss or liability caused by the failure to give notice. If any municipality has annexed any area before October 1, 1975, and the legal description in the petition for annexation did not include the entire adjacent highway, any such annexation shall be valid and any highway adjacent to the area annexed shall be considered to be annexed notwithstanding the failure of the petition to annex to include the description of the entire adjacent highway.
    When annexing territory separated from the municipality by a lake, river, or other waterway, the municipality also annexes the portion of the lake, river, or other waterway that would make the municipality and territory contiguous if the lake, river, or other waterway is under the jurisdiction and control of another unit of local government or the State, or the federal government if allowed under federal law, except for any territory within the corporate limits of another municipality.
    Any annexation, disconnection and annexation, or disconnection under this Article of any territory must be reported by certified or registered mail by the corporate authority initiating the action to the election authorities having jurisdiction in the territory, the Department of Transportation, and the post office branches serving the territory within 30 days of the annexation, disconnection and annexation, or disconnection.
    Failure to give notice to the required election authorities or post office branches will not invalidate the annexation or disconnection. For purposes of this Section "election authorities" means the county clerk where the clerk acts as the clerk of elections or the clerk of the election commission having jurisdiction.
    No annexation, disconnection and annexation, or disconnection under this Article of territory having electors residing therein made (1) before any primary election to be held within the municipality affected thereby and after the time for filing petitions as a candidate for nomination to any office to be chosen at the primary election or (2) within 60 days before any general election to be held within the municipality shall be effective until the day after the date of the primary or general election, as the case may be.
    For the purpose of this Section, a toll highway or connection between parcels via an overpass bridge over a toll highway shall not be considered a deterrent to the definition of contiguous territory.
    When territory is proposed to be annexed by court order under this Article, the corporate authorities or petitioners initiating the action shall notify each person who pays real estate taxes on property within that territory unless the person is a petitioner. The notice shall be served by certified or registered mail, return receipt requested, at least 20 days before a court hearing or other court action. If the person who pays real estate taxes on the property is not the owner of record, then the payor shall notify the owner of record of the proposed annexation.

65 ILCS 5/7-1-2

    (65 ILCS 5/7-1-2) (from Ch. 24, par. 7-1-2)
    Sec. 7-1-2. (a) A written petition signed by a majority of the owners of record of land in the territory and also by a majority of the electors, if any, residing in the territory shall be filed with the circuit court clerk of the county in which the territory is located, or the corporate authorities of a municipality may initiate the proceedings by enacting an ordinance expressing their desire to annex the described territory. A person owning land underlying a highway shall not be considered an owner of record for purposes of this petition unless that person owns some land not underlying a highway proposed to be annexed in the petition for annexation. No tract of land in excess of 10 acres in area may be included in the ordinances of a municipality initiating the proceedings, however, without the express consent of the owner of the tract unless the tract (i) is subdivided into lots or blocks or (ii) is bounded on at least 3 sides by lands subdivided into lots or blocks. A tract of land shall be deemed so bounded if it is actually separated from the subdivision only by the right-of-way of a railroad or other public utility or at a public highway. The petition or ordinance, as the case may be, shall request the annexation of the territory to a specified municipality and also shall request that the circuit court of the specified county submit the question of the annexation to the corporate authorities of the annexing municipality or to the electors of the unincorporated territory, as the case may be. The circuit court shall enter an order fixing the time for the hearing upon the petition, and the day for the hearing shall be not less than 20 nor more than 30 days after the filing of the petition or ordinance, as the case may be.
    (b) The petitioners or corporate authorities, as the case may be, shall give notice of the annexation petition or ordinance, as the case may be, not more than 30 nor less than 15 days before the date fixed for the hearing. This notice shall state that a petition for annexation or ordinance, as the case may be, has been filed and shall give the substance of the petition, including a description of the territory to be annexed, the name of the annexing municipality, and the date fixed for the hearing. This notice shall be given by publishing a notice at least once in one or more newspapers published in the annexing municipality or, if no newspaper is published in the annexing municipality, in one or more newspapers with a general circulation within the annexing municipality and territory. A copy of this notice shall be filed with the clerk of the annexing municipality and the municipal clerk shall send, by registered mail, an additional copy to the highway commissioner of each road district within which the territory proposed to be annexed is situated. If a municipal clerk fails to send the notice to a highway commissioner as required by this subsection, the municipality shall reimburse the road district served by that highway commissioner for any loss or liability caused by that failure. Any notice required by this Section need not include a metes and bounds legal description of the territory to be annexed, provided that the notice includes: (i) the common street address or addresses and (ii) the property index number ("PIN") or numbers of all the parcels of real property contained in the territory to be annexed.
    (c) The petitioners or corporate authorities, as the case may be, shall pay to the clerk of the circuit court $10 as a filing and service fee, and no petition or ordinance, as the case may be, shall be filed until this fee is paid.
    (d) No petitioner may withdraw from this petition except by consent of the majority of the other petitioners, or where it is shown to the satisfaction of the court that the signature of the petitioner was obtained by fraud or misrepresentation.
    (e) If a State charitable institution is situated upon a tract or tracts of land that lie partly within and partly without the corporate limits of any municipality, the corporate authorities of the municipality may by resolution without any petition or proceedings required by this Article but with the written consent of the Director of the State Department having jurisdiction of the institution, annex any part or all of the tracts lying without the corporate limits.
    (f) If real estate owned by the State of Illinois or any board, agency, or commission of the State is situated in unincorporated territory adjacent to a municipality, the corporate authorities of the municipality may annex any part or all of the real estate only with the written consent of the Governor or the governing authority of the board, agency, or commission, without any petition or proceedings required by this Article by resolution of the corporate authorities. This requirement does not apply, however, to State highways located within territory to be annexed under this Article.

65 ILCS 5/7-1-3

    (65 ILCS 5/7-1-3) (from Ch. 24, par. 7-1-3)
    Sec. 7-1-3. After the filing of the petition but not less than 5 days prior to the date fixed for the hearing, any interested person may file with the circuit clerk his objections (1) that the territory described in the petition or ordinance, as the case may be, is not contiguous to the annexing municipality, (2) that the petition is not signed by the requisite number of electors or property owners of record, (3) that the description of the territory contained in the petition or ordinance, as the case may be, is inadequate, or (4) that the objector's land is located on the perimeter of such territory, that he does not desire annexation, and that exclusion of his land will not destroy the contiguity of such described property with the annexing municipality.

65 ILCS 5/7-1-4

    (65 ILCS 5/7-1-4) (from Ch. 24, par. 7-1-4)
    Sec. 7-1-4. The cause shall be heard without further pleadings. At the hearing the objector may be heard in person or by counsel.
    Prior to hearing evidence on the validity of the annexation petition or ordinance, the court shall hear and determine any objection under sub-paragraph (4) of Section 7-1-3. If the court is satisfied that such objection is valid, it shall order the petition or ordinance to be amended to eliminate such objector's land from the territory sought to be annexed. Thereafter upon this hearing the only matter for determination shall be the validity of the annexation petition or ordinance, as the case may be, and the decision of the court shall be final. All petitions shall be supported by an affidavit of one or more of the petitioners, or some one on their behalf, that the signatures on the petition represent a majority of the property owners of record of land in the territory described and a majority of the electors of the territory therein described. Petitions so verified shall be accepted as prima facie evidence of such facts. If the court finds that (1) the annexation petition is not signed by the requisite number of electors or property owners of record; or (2) that the described property is not contiguous to the annexing municipality; or (3) that the description is materially defective; or (4) that the petition or ordinance, as the case may be, is otherwise invalid, the court shall dismiss the petition or ordinance, as the case may be.
    But if the court finds that the petition or ordinance, as the case may be, is valid, the court shall (1) enter an order describing the territory to be annexed, (2) find that the petition or ordinance, as the case may be, conforms to this Article, and (3) direct that the question of annexation be submitted to the corporate authorities of the annexing municipality or to the electors of the unincorporated territory, as the case may be, for final action. A certified copy of the order of the court directing that the question of annexation be submitted to the corporate authorities shall be sent to the clerk of the annexing municipality.
    Appeals shall lie from any final order of the court as in other civil actions.

65 ILCS 5/7-1-5

    (65 ILCS 5/7-1-5) (from Ch. 24, par. 7-1-5)
    Sec. 7-1-5. After the clerk receives the certified copy of the order of the court, the corporate authorities of the annexing municipality shall proceed to consider the question of the annexation of the described territory. A majority vote of the corporate authorities then holding office is required to annex. The vote shall be by "ayes" and "noes" entered on the legislative records. Except as is otherwise provided in Section 7-1-1, this decision shall be effective after the expiration of 30 days unless a referendum on the question is ordered by the corporate authorities or unless a petition for a referendum is filed. If no referendum is ordered by the corporate authorities and no petition for a referendum is filed, the municipal clerk shall, promptly after the expiration of the 30 days, send written notice of the annexation by registered mail to the highway commissioner of each road district within which the annexed territory is described. If a municipal clerk fails to send any notice to a highway commissioner as required by this Section, the municipality shall reimburse the road district served by that highway commissioner for any loss or liability caused by that failure.

    (2) Every owner of record of commercial or industrial property of 50 acres or more which lies within the territory to be annexed shall be notified by the petitioner or corporate authorities, as the case may be, by certified mail, of the public hearing, any meeting of the corporate authorities where a vote is to be taken in regard to the proposed annexation, and any impending referendum to annex, at least 30 days prior to any such public hearing, meeting, or referendum.
    (3) Notwithstanding the provisions of Section 7-1-5, the ordinance shall be enacted not less than 30 and not more than 45 days after the public hearing.

    Sec. 7-1-5.2. Annexation of contiguous territory contributing to groundwater contamination.
    (a) The corporate authorities of a municipality adjoining unincorporated territory in which the majority of residential, business, commercial, and industrial structures and improvements are contaminating the groundwater of the State through the direct discharge of sanitary sewerage into underground mines and Class 5 injection wells, as defined by the Illinois Groundwater Pollution Control Code, may annex that territory, in whole or in part, after adopting an ordinance to that effect and filing it with the clerk of the circuit court of the county in which the territory is located. The ordinance shall certify the following:
        (1) That the territory sought to be annexed is
    
contiguous to the municipality seeking annexation and not within the corporate boundaries of any other municipality.
        (2) That a survey of all residential, business,
    
commercial, and industrial structures and improvements in the territory sought to be annexed has shown that a majority of those structures and improvements are discharging untreated sanitary sewerage directly into underground mines or Class 5 injection wells as defined by the Illinois Groundwater Pollution Control Code.
        (3) That the corporate authorities of the
    
municipality seeking annexation have approved a plan for eliminating groundwater contamination by providing sanitary sewerage collection and treatment facilities to serve the territory sought to be annexed within 5 years from the date of annexation to the municipality.

The date for the hearing shall be not less than 20 nor more than 30 days after the filing of the ordinance. The corporate authorities shall give notice of the proposed annexation not more than 30 nor less than 15 days before the date fixed for the hearing. This notice shall state that an ordinance has been filed and shall give the substance of the ordinance, including a description of the territory to be annexed, the name of the annexing municipality, and the date fixed for the hearing.

    (c) The cause shall be heard without further pleadings. At the hearing the objectors may be heard in person or by counsel. The court shall hear and determine only objections set forth in subsection (b).

    If the court finds that the ordinance is valid, the court shall (i) enter an order describing the territory to be annexed, (ii) find that the ordinance complies with this Section, and (iii) direct that the question of annexation be submitted to the corporate authorities of the annexing municipality for final action. A certified copy of the order of the court directing that the question of annexation be submitted to the corporate authorities shall be sent to the clerk of the annexing municipality. A final order of the court may be appealed as in other civil actions.
    (d) After the municipal clerk receives the certified copy of the court order, the corporate authorities of the annexing municipality shall proceed to consider the question of the annexation of the described territory. A majority vote of the corporate authorities then holding office is required to annex the territory. The vote shall be by "ayes" and "nays" entered on the legislative records of the municipality. Except as otherwise provided in Section 7-1-1, this decision of the corporate authorities shall be effective after the expiration of 30 days.

65 ILCS 5/7-1-5.3

    (65 ILCS 5/7-1-5.3)
    Sec. 7-1-5.3. Planned unit development; rail-trail. When a developer petitions a municipality to annex property for a planned unit development of residential, commercial, or industrial sub-divisions that is located adjacent to a former railroad right-of-way that has been converted to a recreational trail ("rail-trail") that is owned by the State, a unit of local government, or a non-profit organization, the municipality shall notify the State, unit of local government, or non-profit organization and furnish the proposed development plans to the State, unit of local government, or non-profit organization for review. The municipality shall require the developer petitioning for annexation to reasonably accommodate the rail-trail and modify its proposed development plans to ensure against adverse impacts to the users of the rail-trail or the natural and built resources within the right-of-way. If the municipality does not require the developer to make a modification prior to annexation, the municipality shall provide a written explanation to the State, unit of local government, or non-profit organization owning the rail-trail. The intent of this review and planning process is to ensure that no development along a rail-trail negatively affects the safety of users or the natural and built resources within the right-of-way.

    (65 ILCS 5/7-1-6) (from Ch. 24, par. 7-1-6)
    Sec. 7-1-6. (a) If the vote is in favor of annexing the described territory, the corporate authorities on their own motion may order a referendum on the question. If the corporate authorities reject annexation, or do not order a referendum, then within the 30 day period a petition may be filed with the municipal clerk requesting that the question of the annexation of the described territory be submitted to the electors of the annexing municipality. The petition shall be signed by electors of the annexing municipality equal in number to 10% of the entire vote cast for all candidates for mayor or president of the annexing municipality at the last preceding general municipal election. The municipal clerk shall certify the proposition to the proper election authority for submission to the electors at an election in accordance with the general election law and shall send, by registered mail, a notice of the date of the prospective referendum to the highway commissioner of each road district within which the described territory is situated.
    (b) If a majority of the electors voting on this question favor annexation, the decision of the corporate authorities, if in favor of annexation, shall be final. If a majority of the electors voting on this question favor annexation, after the corporate authorities have rejected annexation, the decision of the electors shall be final. In either case, the described territory shall thereupon be a part of the annexing municipality.
    (c) If the vote is against annexation, no further proceedings shall be had on that petition for annexation, and no action in favor of the annexation shall have any effect. After the referendum, the municipal clerk shall promptly send written notice of the results of the referendum by registered mail to the highway commissioner of each road district within which the described territory is situated. This, however, shall not prevent the subsequent annexation of the described territory upon another petition.
    (d) If a municipal clerk fails to send any notice to a highway commissioner as required by this Section, the municipality shall reimburse the road district served by that highway commissioner for any loss or liability caused by that failure.

The clerk of the circuit court shall certify the question for submission.
    (b) If a majority of those casting ballots favor annexation, the described territory shall, except as otherwise provided in Section 7-1-1, thereupon be a part of the annexing municipality. Within 15 days after the referendum, the clerk of the annexing municipality shall promptly send written notice of the results of the referendum by registered mail to the highway commissioner of each road district within which the territory is situated.
    (c) If a municipal clerk fails to send any notice to a highway commissioner as required by this Section, the municipality shall reimburse the road district served by that highway commissioner for any loss or liability caused by that failure.

Any territory which is not within the corporate limits of any municipality but which is contiguous to a municipality at the time of annexation and which territory has no electors residing therein, or any such territory with electors residing therein, may be annexed to the municipality in the following manner: a written petition signed by the owners of record of all land within such territory and by at least 51% of the electors residing therein shall be filed with the municipal clerk. The petition shall request annexation and shall state that no electors reside therein or that at least 51% of such electors residing therein join in the petition, whichever shall be the case, and shall be under oath. The corporate authorities of the municipality to which annexation is sought shall then consider the question of the annexation of the described territory. A majority vote of the corporate authorities then holding office is required to annex. The vote shall be by "yeas" and "nays" entered on the legislative records. A copy of the ordinance annexing the territory together with an accurate map of the annexed territory shall be recorded with the recorder and filed with the County Clerk within the county wherever the annexed territory is located.

    Sec. 7-1-31. After a part of a municipality is disconnected and annexed to another municipality, the indebtedness and liabilities of the municipality from which the part is disconnected shall be assumed and paid by the enlarged annexing municipality, in the same proportion as the taxable property in the disconnected part bears to the taxable property in the municipality from which the part was disconnected as it existed immediately before the disconnection, according to the last assessment for taxation. This duty to assume and pay a proportionate share of indebtedness and liabilities shall also apply to the indebtedness and liabilities of the school district or township in which the disconnected part was situated.
    The amount of the indebtedness and liabilities to be assumed and paid by the enlarged annexing municipality shall be determined by the corporate authorities of the annexing municipality and of the municipality from which a part was disconnected, or, as the case may be, by the school authorities of the school district or township in which the disconnected part was situated.

    Sec. 7-1-33. Upon annexation, the title and possession of all municipal and school property located in the annexed part vests in the annexing municipality. There shall be an adjustment of the municipal and school properties owned by the municipality, school district, or township from which a part is disconnected in order that all of this property may be divided between that municipality, school district, or township and the enlarged annexing municipality, on the same basis and by the same authorities or court as is provided in Sections 7-1-31 and 7-1-32 for a division of indebtedness and liabilities. If the public property that becomes vested in the enlarged annexing municipality because of its location in the part that was disconnected and annexed exceeds in value the proportionate part to which the annexing municipality is thus entitled, then the enlarged annexing municipality shall pay to the municipality, school district, or township, as the case may be, a sum equal to the difference between what it received and what it should have received on the basis specified in Sections 7-1-31 and 7-1-32 for the division of indebtedness and liabilities. Likewise, if the public property located in that part of the municipality, school district, or township, that remains after the disconnection occurs, exceeds in value the proportionate part to which the municipality, school district, or township is entitled, then the municipality, school district, or township, as the case may be, shall pay to the enlarged annexing municipality a sum equal to the difference between what it received and what it should have received on the basis specified in Sections 7-1-31 and 7-1-32 for the division of indebtedness and liabilities.
