When a listing near Franklin Grove mentions a lot number, you'll need the Dixon plat map to make sense of it. This Dixon guide covers: where to request a copy, how a plat differs from a parcel map, and what to look for on the sheet.
Tracking down the Dixon plat map
For land around Ashton, the deed or parcel record often names the subdivision and plat reference; use it to request a copy.
The viewer Lee County publishes
Begin with the Lee County Parcel Viewer; it maps every assessed parcel around Franklin Grove and Nelson. For acreage around Sublette, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. If the land is near Nelson, the record panel normally shows the owner of record, acreage on the tax roll, a parcel ID and often a sale date.
Who handles what
Recorded documents for a parcel near Sublette are with the county Recorder of Deeds (in many counties the County Clerk and Recorder), usually searchable by name or document number. Zoning, permits and septic questions near Nelson need the planning or permitting office, town or county, depending on location.
The paper trail behind a parcel
The map is an index, not the title: deeds, plats and easements covering ground around Nelson are filed with the county Recorder of Deeds (in many counties the County Clerk and Recorder). If the land is near Harmon, have ready the book and page listed on the parcel record so staff can find the deed fast.
How land is described here
Illinois uses the Public Land Survey System, which means a tract near Harmon is described by section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though sections near Harmon can be irregular. Write down the legal description for the tract near Amboy when you talk to a surveyor.
Dixon and the county around it
Dixon is part of Lee County, Illinois, and the county assessor maps its lots. Dixon is also the county seat, handy when you need recorded documents. For land near Harmon, the municipality handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the city limits near Ashton often follows county rules rather than the town's.
Replats and vacations
Lots near Nelson can be combined or reconfigured by a replat, so check for later filings; street vacations near Sublette show up in the records too.
When there's no plat
Acreage around Ashton outside a subdivision is often described by metes and bounds or survey description; look for a recorded survey for land near Franklin Grove.
Neighboring parcel maps
Lee County touches Bureau County, DeKalb County, LaSalle County, Ogle County, and Whiteside County, all with their own assessor records. A tract near the line by Harmon may be split across two assessors' files, so check the adjacent map too. For a home near Nelson, our state page lists each neighboring county map for Illinois.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Nelson, so load it before you lose signal. A screenshot of the parcel near Harmon with its ID helps when you meet an owner or agent.
What the map can't tell you
Tax maps are drawn for assessment, not measured on the ground, so the edge of a yard near Harmon can sit a few yards off the line on screen. Records update in batches, so a fresh transfer around Franklin Grove might lag behind.
Plat map vs. parcel map

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.
