Illinois General Assembly - Illinois Compiled Statutes

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.

by any municipality by which it is bounded in whole or in part,
by the passage of an ordinance to that effect after notice is given as
provided in subsection (b) of this Section. Land or property that is used for agricultural purposes or to produce agricultural goods shall not be annexed pursuant to item  (g). Nothing in this Section shall subject any railroad property to the zoning or jurisdiction of any municipality annexing the property under this Section. The
ordinance shall describe the territory annexed and a copy thereof together
with an accurate map of the annexed territory shall be recorded in the
office of the recorder of the county wherein the annexed territory is
situated and a document of annexation shall be filed with the county clerk
and County Election Authority. Nothing in this Section shall be construed
as permitting a municipality to annex territory of a forest preserve
district in a county with a population of 3,000,000 or more without
obtaining the consent of the  district pursuant to Section 8.3 of the
Cook County Forest Preserve District Act nor shall anything in this Section be construed as permitting a municipality to annex territory owned by a park district without obtaining the consent of the district pursuant to Section 8-1.1 of the Park District Code.

(b)  The corporate authorities shall cause notice, stating that annexation of the territory described in the notice is contemplated under this Section, to be published once, in a newspaper of general circulation within the territory to be annexed, not less than 10 days before the passage of the annexation ordinance, and for land annexed pursuant to item (g) of subsection (a) of this Section, notice shall be given to the impacted land owners. The corporate authorities shall also, not less than 15 days before the passage of the annexation ordinance, serve written notice, either in person or, at a minimum, by certified mail, on the taxpayer of record of the proposed annexed territory as appears from the authentic tax records of the county. When the territory to be annexed lies wholly or partially within a township other than the township where the municipality is situated, the annexing municipality shall give at least 10 days prior written notice of the time
and place of the passage of the annexation ordinance to the township
supervisor of the township where the territory to be annexed lies. If the territory to be annexed lies within the unincorporated area of a county, then the annexing municipality shall give at least 10 days' prior written notice of the time
and place of the passage of the annexation ordinance to the corporate authorities of the county where the territory to be annexed lies.

(c)  When notice is given as described in subsection (b) of this Section, no other municipality may annex the proposed territory for a period of 60 days from the date the notice is mailed or delivered to the taxpayer of record unless that other municipality has initiated annexation proceedings or a valid petition as described in Section 7-1-2, 7-1-8, 7-1-11 or 7-1-12 of this Code has been received by the municipality prior to the publication and mailing of the notices required in subsection (b).
