The Orland Park plat map: start here
For a lot in Orland Park, the deed or parcel record often names the subdivision and plat reference; that makes the request quick.
Pulling up a parcel
Your first stop is the Will County parcel viewer; it covers every tax parcel from Frankfort to Homer Glen. For a tract near Lemont, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. With a lot near Frankfort, the parcel card usually lists the owner of record, assessed acreage, the parcel number and sometimes recent sales.
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 Tinley Park may show up in two county records, so look at the adjacent map as well. For a home near Tinley Park, our state page links each bordering county map across Illinois.
Orland Park, IL: the basics
Orland Park sits in Will County, Illinois, so its parcels are on the county's map. Near Frankfort, city or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Acreage past the city limits out by Mokena generally answers to county rules rather than the town's.
A word on accuracy
Parcel lines are drawn for taxes, not measured on the ground, so the edge of a yard near New Lenox often sits a few yards off the line on screen. For a tract near Tinley Park, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Places you'll see on the map
Joliet is the county seat, home to the main records offices. You'll also find Tinley Park, Homer Glen, Mokena, and Frankfort, where town lots give way to larger tracts. About 700,728 people call Will County home (Census estimate, 2023) spread over roughly 836 square miles. Will County was organized in 1836, and some chains of title near Frankfort are long. Features like Channahon State Park make handy reference points on the map near Frankfort.
When there's no plat
Acreage around New Lenox outside a subdivision may have no plat at all; look for a recorded survey for land near Homer Glen.
How a plat differs from the tax map
The Will County parcel viewer draws parcels for taxes, whereas the plat carries surveyed dimensions.
Reading the plat sheet
For acreage around Tinley Park, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
Requesting the plat
In and around Homer Glen, many recorder offices offer an online index, otherwise call or visit with the reference; copy fees are usually small.
When a plat changes
An amended plat may change lots around Lemont, so check for later filings; street vacations show up in the records too.
Deeds, plats and who keeps them
The map is an index, not the title: recorded deeds, plats and easements covering ground around Mokena are filed with the county Recorder of Deeds (in many counties the County Clerk and Recorder). Inherited tracts near Mokena can go back through many deeds, and a title company is worth hiring on a real sale.

Questions about what you can build around Frankfort are for the local planning and health departments, depending on whether the land is inside town limits.
