Trying to understand lot lines near Homer Glen? What you want is the Crest Hill plat map, because the recorded plat shows how the land was divided. Covered here for Crest Hill: where to request a copy, how a plat differs from a parcel map, and what to look for on the sheet.
Who keeps the Crest Hill plat map
For a lot in Crest Hill, the deed usually cites the plat; that makes the request quick.
Where the parcel data lives
Lots and tracts near Homer Glen appear on the Will County parcel viewer, which opens without registering. For acreage around Shorewood, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. If the land is near Lockport, a pop-up or side panel usually lists the owner of record, acreage on the tax roll, the parcel number and often a sale date.
City limits and county records
Crest Hill is part of Will County, Illinois, and the county assessor maps its lots. For property near Romeoville, 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 near Shorewood generally falls under county rules instead.
Neighboring parcel maps
Will County borders Cook County, DuPage County, Grundy County, Kankakee County, and Kendall County, and each of those keeps its own parcel map. Ground near Bolingbrook that runs to the line can show up in two county records, so open the adjacent map before you assume the acreage. Near Romeoville, our state page lists every bordering county map for Illinois.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Homer Glen, but coverage can be spotty out of town. A saved image of the lot near Shorewood and its lines is a good backup.
Getting answers from the right desk
Recorded documents for a parcel near Romeoville come from the county Recorder of Deeds (in many counties the County Clerk and Recorder), sometimes only in person. Zoning, permits and septic questions near Rockdale need the planning or permitting office, town or county, depending on location.

Details on the Crest Hill plat map

Sections, lots and bearings

Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though real sections near Lockport vary in size. Copy the legal description from the record for the parcel near Rockdale for any title or survey request.
A quick look at the area

Roughly 700,728 people call Will County home (Census estimate, 2023) on some 836 square miles. Will County dates to 1836, and some chains of title near Romeoville are long.

Limits of the parcel data
Listed acreage is an assessed number; only a licensed surveyor can set the real boundary for a parcel near Shorewood. Around Lockport, records update in batches, so a deed recorded last month might lag behind.
Metes and bounds instead
Rural land near Shorewood that was never subdivided is often described by metes and bounds or survey description; look for a recorded survey for land there.
Backing up the map with records
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Homer Glen are filed with the county Recorder of Deeds (in many counties the County Clerk and Recorder). Long-held tracts near Bolingbrook may sit on many deeds, and a title company earns its fee if money is changing hands.
Amended plats
An amended plat may change lots around Rockdale, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
Ordering the Crest Hill plat map
