Land questions in Lee County start in the same place: the official parcel map. Here's how to use the Lee County plat book to find owners, acreage and boundary lines, and where it falls short.
Read on for the official viewer, a short orientation from Ashton out to The Burg, and the land-record steps that back up what you see on screen.
What the map covers, from Dixon to the back roads
Parcel searches in Lee County tend to center on Dixon, the county seat, plus Amboy, Ashton, Compton, and Franklin Grove. Don't overlook unincorporated places like Lee Center, Nachusa, and Binghampton, where rural homesites often come up. The county's land area is about 725 square miles, and the Census Bureau estimated 33,654 residents there in 2023. Expect suburban-style lots near Ashton and plenty of rural ground once the subdivisions thin out.
Where to find a Lee County plat book in Illinois
A plat book is the paper cousin of the online parcel map: a township-by-township atlas with owner names, handy in a truck near Dixon. Ownership around Dixon changes every year, so the online map is the better check on who owns a tract today. If a printed book and the online map disagree about a tract near Franklin Grove, the recorded deed decides.
Getting into the Lee County Parcel Viewer
For parcels from Franklin Grove to The Burg, the Lee County Parcel Viewer is the county's own public map. You'll see a disclaimer screen first; accept it and the map loads. Rural tracts in Lee County often have no street address, so try an owner search or simply pan to the area and click. Our Lee County listing carries the same link plus neighboring maps.
Property lines in Lee County, Illinois
Zoom in far enough on a lot in Ashton and you may notice lines crossing driveways or splitting sheds, a normal quirk of tax mapping. Because Illinois is a section-township-range state, the legal description of a rural tract in Lee County reads like a grid reference that you can match to the section lines on the map. If a neighbor's fence near Compton and the map disagree, neither one is proof. A survey is.
Behind the map: land records in Lee County
The map near Franklin Grove is only as good as the deeds behind it, and those are kept in the county's recording office. Recording offices go by different titles from state to state, including register of deeds, recorder, county clerk and clerk of court; the official Lee County website names the one that handles deeds. The parcel record often lists a deed book and page or an instrument number, which is how you request a copy of the recorded deed for a tract near Dixon.
Who needs this map

- A hunter driving the back roads near The Burg can match a promising woodlot to an owner name in seconds.

Hunting land and landowner permission in Lee County
Near Amboy, a single field edge can separate two owners with very different answers about access; the map tells you which is which. Check the Illinois Department of Natural Resources for public hunting areas and current regulations before you hunt near Dixon. A landowner near The Burg is more likely to say yes to a hunter who names the exact parcel and offers a phone number.
Acreage and vacant lot search
How to work the Lee County plat book for open land:
- Follow the roads out of Dixon with aerials on and mark every tract without a rooftop.
- Check who owns each open tract near Amboy and where the tax bill goes.
- Measure the road frontage on the map; a sliver of frontage on a road outside Dixon may not be enough for a driveway permit.
- Line up the assessed land values of a few neighboring tracts near Amboy to sanity-check an asking price.
- For a tract near Dixon, confirm zoning, septic suitability and flood status before you make an offer.

The Lee County economy in brief
The Census Bureau's County Business Patterns counted 704 business establishments in Lee County in 2022, and the largest groups were retail trade, other services, and health care and social assistance. What stands out is utilities, nursing and residential care, and building material and garden supply dealers: those sectors make up a much larger slice of local businesses than they do nationally.
Before you rely on the data
If a tract near Amboy changed hands recently, the recorded deed is more current than the map. Acreage on the Lee County map is a tax figure; a survey is what a lender or buyer should rely on.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
