The county board of any county may, in addition to taxes levied and collected for other county purposes, and in addition to the tax rate of .10% or a greater rate, as the case may be in certain counties, of the value, as equalized or assessed by the Department of Revenue, now provided for county purposes, annually levy and collect a tax not exceeding .015% or the rate limit in effect on July 1, 1967, whichever is greater, of the value, as equalized or assessed by the Department of Revenue, upon all property within the county for the purpose of purchasing, erecting, leasing or otherwise providing, establishing, supporting and maintaining such a shelter care or detention home if this Act has been adopted and the levy and collection of such tax authorized by the legal voters of the county in the manner provided by Section 6 of this Act. However, in counties with over 300,000 but less than 1,000,000 inhabitants that establish a shelter care or detention home by majority vote of their county boards, taxes for construction and maintenance of the home may be extended without adoption of this Act by the legal voters of the counties and without a referendum. They may levy and collect a tax not exceeding .04% of the value, as equalized or assessed by the Department of Revenue, upon all property within the county, for the purpose of constructing a home, and a tax of .02% for operation of the home.
     After September 20, 1987, in all counties subject to this Section, the additional tax authorized to be annually levied and collected pursuant to this Section may be increased to a rate not exceeding .10% if approved by a referendum submitted to the voters of such county pursuant to ordinance or resolution of the county board and in accordance with the general election law. The proposition shall be in substantially the following form:
————————————————————–
    Shall the county increase the
additional annual tax levy authorized
by Section 5 of the County Shelter            YES
Care and Detention Home Act for shelter
care or detention homes for minors in     ——————–
….. county from the current rate of
…..% to …..% of the equalized             NO
assessed value of real property in
….. county?
————————————————————–
     If a majority of the votes cast for and against such proposition shall be for such proposition, the county shall be authorized to levy such additional tax at the rate authorized by the referendum.
     The foregoing limitations upon tax rates, insofar as they are applicable to counties of less than 1,000,000 population, may be increased or decreased under the referendum provisions of the Property Tax Code.
     Taxes collected under this Act shall not be expended for any purpose except those purposes authorized by this Act.
