What does the Illinois Plat Act require for a 20-acre parcel being divided into residential lots?

The Illinois Plat Act requires a recorded plat of the subdivision for a 20-acre parcel being divided into residential lots. This statute is established to ensure that any subdivision of land, particularly when it involves creating multiple residential lots, is done in a manner that is properly documented and publicly accessible.

A recorded plat provides an official map or plan that delineates the boundaries of each individual lot within the subdivision, as well as streets, easements, and other pertinent information. The requirement for a recorded plat serves several important functions: it protects future property owners by clearly indicating property lines and zoning information, it helps local authorities manage land use planning efficiently, and it contributes to the orderly development of residential areas.

In contrast, the other options do not fulfill the legal requirements set forth by the Illinois Plat Act. A metes and bounds legal description alone may not provide the comprehensive overview necessary for proper subdivision documentation. Similarly, while detailed plats might be informative, they lack the legal standing afforded by a recorded plat. A record of conveyance and restrictions, while relevant for future owners, does not replace the necessity of having an officially recorded plat for the subdivision itself.
