When a deed near Frankfort says lot and block, you'll need the Mokena plat map to make sense of it. Covered here for Mokena: where plats are filed, how a plat differs from a parcel map, and what to look for on the sheet.
Who keeps the Mokena plat map
For a subdivision near New Lenox, the deed usually cites the plat; use it to request a copy.
Where the parcel data lives
Property in and around New Lenox are published on the Will County parcel viewer, which opens without registering. If the land is near Homer Glen, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For property near Frankfort, write down the parcel ID before closing the panel; every clerk in the county uses it to find the file.
When there's no plat
Rural land near Tinley Park that was never subdivided may have no plat at all; look for a recorded survey for land near Frankfort.
Sections, lots and bearings
Illinois is laid out under the Public Land Survey System, which means a tract near Orland Park is described by section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near New Lenox vary in size. Copy the legal description from the record for the parcel near Tinley Park before you request a deed or survey.
City limits and county records
Mokena lies within Will County, Illinois, so its parcels are on the county's map. Out toward Homer Glen, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the city limits near New Lenox often falls under county rules instead.
Neighboring parcel maps
Will County meets Cook County, DuPage County, Grundy County, Kankakee County, and Kendall County; every one of them runs a separate parcel map. Ground near New Lenox that runs to the line may be split in two county records, so check the neighboring map before you assume the acreage. On ground around Homer Glen, the Platbookmapper state page lists each bordering county map across Illinois.
Backing up the map with records
The map is an index, not the title: recorded deeds, plats and easements covering ground around Frankfort sit with the county Recorder of Deeds (in many counties the County Clerk and Recorder). For a tract near New Lenox, have ready the instrument number shown in the record panel to skip a name search.
How a plat differs from the tax map
Where lines don't match in Mokena, go with the plat and a surveyor's work.
Before you lean on the lines
Listed acreage is an assessed number; just a licensed surveyor establishes the real lines for a parcel near Homer Glen. For property near Orland Park, records update in batches, so a deed recorded last month might lag behind.
Field tips
