A Naperville property search: start here
Use the Will County parcel viewer for a Naperville property search; addresses, names and parcel numbers all work.
The free map to start with
Begin with the Will County parcel viewer; it covers every tax parcel around Crest Hill and Lockport. In and around Lockport, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. For a home near Crest Hill, write down the parcel ID before closing the panel; every office in the county asks for it first.
A word on accuracy
Parcel lines are drawn for taxes, not surveyed, so a tree line near Lemont often sits several feet off the line on screen. For a parcel near Lemont, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Recorded documents worth pulling
The map is an index, not the title: deeds, plats and easements covering ground around Lemont are kept by the county Recorder of Deeds (in many counties the County Clerk and Recorder). If the land is near Lockport, have ready the book and page from the tax record and the lookup takes minutes.
Naperville and the county around it
Naperville sits in Will County, Illinois, which means parcel data comes from the county. For a parcel near Lockport, city or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Land beyond the town limits out by Lemont usually follows county rules rather than the town's.
