Tracking down the Tinley Park plat map
For a lot in Tinley Park, look for the plat book reference on the parcel record; bring that to the recorder's office or its online index.
The free map to start with
Begin with the Will County parcel viewer; it covers each assessed parcel around Orland Park and Frankfort. Around Frankfort, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. If you're looking near Orland Park, the parcel card usually lists the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
Next door to Will County
Will County meets Cook County, DuPage County, Grundy County, Kankakee County, and Kendall County, and each of those keeps its own parcel map. Acreage along the edge near Park Forest may be split in two county records, so open the neighboring map as well. If the land is near Park Forest, our state page lists each bordering county map across Illinois.
Metes and bounds instead
Rural land near New Lenox that was never subdivided may have no plat at all; the deed and any recorded survey describe it instead.
Getting your bearings
Joliet holds the county offices, home to the main records offices. You'll also find Orland Park, Mokena, Frankfort, and Homer Glen. Around 700,728 people call Will County home (Census Bureau estimate, 2023) spread over about 836 square miles. Will County was organized in 1836, and some chains of title near New Lenox are long. Landmarks such as Channahon State Park make handy reference points on the map near Homer Glen.
Where Tinley Park fits in
The city lies within Will County, Illinois, which means parcel data comes from the county for land near Lockport. Out toward Frankfort, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the town limits near Frankfort generally follows county rules rather than the town's.
Taking the map into the field
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Orland Park, though signal can drop in rural spots. A printout of the tract near Park Forest keeps working without signal.
Where the recorded documents are
For anything that matters, pull the recorded deed through the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Homer Glen only summarizes it. Long-held tracts near Park Forest may sit on several deeds, and a title company is worth hiring if money is changing hands.
Two different maps

Which office to call
Questions about value or the owner field for land near Homer Glen are handled by the Supervisor of Assessments, working with township assessors, which maintains the tax roll.

Amended plats
An amended plat may change lots around Homer Glen, so check for later filings; vacated streets or alleys also get recorded.
How land is described here
Illinois follows the Public Land Survey System, which means a tract near Homer Glen 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 Orland Park vary in size. Copy the legal description from the record for the parcel near Homer Glen for any title or survey request.
A word on accuracy
The acreage figure is an estimate; just a licensed surveyor establishes the real boundary for a parcel near Homer Glen. With a lot near Homer Glen, owner names and values update on a schedule, so a deed recorded last month may not show yet.
