The viewer Will County publishes
Your first stop is the Will County parcel viewer; it maps every assessed parcel from Crest Hill to Homer Glen. For a tract near Homer Glen, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. Out toward Woodridge, the parcel card usually lists the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
Before you lean on the lines
Acreage on the record is an assessed number; only a licensed surveyor sets the real corners for a parcel near Crest Hill. With a lot near Crest Hill, records update in batches, so a deed recorded last month might lag behind.

Recorded documents for a parcel near Homer Glen are with the county Recorder of Deeds (in many counties the County Clerk and Recorder), sometimes only in person. Building or septic questions for a lot near Lockport need the planning or permitting office, and the answer depends on jurisdiction.
Metes and bounds instead
Acreage around Bolingbrook outside a subdivision is often described by metes and bounds or survey description; the deed and any recorded survey describe it instead.
