If you have a specific use in mind for land near New Lenox, look at the Tinley Park zoning map before anything else: the zoning district decides setbacks, lot size and uses. In this Tinley Park guide: which office sets the rules for a lot, how to match a parcel to its district, and when a variance or rezoning comes up.
Which office controls the Tinley Park zoning map
Inside town or city limits, zoning usually comes from the municipality, so property inside the city follows that code around Naperville. Past the city line, around Homer Glen, the county's ordinance, if any, takes over; confirm with the county office. The quickest way to tell which applies: ask whether the parcel near Park Forest is inside the boundary.
The free map to start with
Go first to the Will County parcel viewer; it includes every tax parcel in the county, Homer Glen included. Closer to Mokena, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. Closer to New Lenox, a pop-up or side panel normally shows the owner of record, acreage on the tax roll, a parcel ID and sometimes recent sales.
Limits of the parcel data
Listed acreage is an estimate; only a licensed surveyor can set the real lines for a parcel near New Lenox. For acreage around Frankfort, records update in batches, so a deed recorded last month can take weeks to appear.
Where the recorded documents are
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Orland Park sit with the county Recorder of Deeds (in many counties the County Clerk and Recorder). Long-held tracts near Frankfort may sit on many deeds, and a title company can sort it out if money is changing hands.
Permits after zoning
Even when zoning allows a use near Orland Park, a building permit is a separate step; health and road departments may weigh in on land there.
Where Tinley Park fits in
Tinley Park lies within Will County, Illinois, so its parcels are on the county's map. For acreage around Frankfort, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Lots just outside the town limits near Homer Glen often falls under county rules rather than the town's.
Land on the county line
Will County borders Cook County, DuPage County, Grundy County, Kankakee County, and Kendall County, and each of those keeps its own parcel map.

Matching a lot to the Tinley Park zoning map
