(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
(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.
