Trying to size up a property near Percy? The Chester GIS map answers most of that, with no account needed. What this Chester guide covers: which viewer to open, how to search it, and what to double-check with records.
Getting started with the Chester GIS map
For a parcel near Steeleville, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Getting to the right map
Go first to the Randolph County ArcGIS parcel map; it covers each assessed parcel from Rockwood to Kaskaskia. For land near Percy, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. If the land is near Ellis Grove, the record panel normally shows the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Offices that can help
If the acreage or value on a parcel near Percy looks off belong with the Supervisor of Assessments, working with township assessors, which maintains the tax roll. Building or septic questions for a lot near Percy go to planning, building or health offices, town or county, depending on location.
Chester and the county around it
Chester sits in Randolph County, Illinois, and the county assessor maps its lots. Chester is also the county seat, which puts the county Recorder of Deeds (in many counties the County Clerk and Recorder) close by. Local government in this town handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records around Sparta. Acreage past the town limits toward Rockwood usually answers to county rules, not municipal ones.
Searching the map
By address works best for lots in Chester; owner names are usually entered last name first. For a home near Ellis Grove, a parcel ID is the most reliable search, and it's printed on tax bills.
Keeping a record
Save a screenshot of the lot near Kaskaskia and its record panel, which helps later when you ask the assessor or a title company.
When the map won't load
If the viewer stalls on a phone near Ellis Grove, switch browsers or turn off pop-up blockers; links occasionally change, and our directory page keeps the current one.
Beyond the parcel lines
Toggling imagery near Kaskaskia helps you see where buildings sit inside the lines.
How land is described here
Illinois uses the Public Land Survey System, so deeds around Steeleville reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though real sections near Ellis Grove vary in size. Keep the legal description for land near Kaskaskia before you request a deed or survey.
Neighboring parcel maps
Randolph County touches Jackson County, Monroe County, Perry County, St. Clair County, and Washington County, and each of those keeps its own parcel map. Acreage along the edge near Rockwood may show up across two assessors' files, so check the adjacent map too. For a home near Percy, the Platbookmapper state page links each bordering county map for Illinois.
The paper trail behind a parcel
When the details count, get the recorded deed from the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Ellis Grove only summarizes it. If the land is near Steeleville, have ready the book and page shown in the record panel and the lookup takes minutes.
Using it on a phone
Most viewers work in a phone browser, handy when you're parked on a road near Percy, though signal can drop in rural spots. A screenshot of the parcel near Ellis Grove with its ID helps when you meet an owner or agent.
Inside the parcel card
Recent sales on nearby lots in this town are a useful starting point; an appraiser is the real authority around Baldwin.
Places you'll see on the map
Chester serves as the county seat, which is where the courthouse records live. Smaller places on the map include Kaskaskia, Ellis Grove, Rockwood, and Steeleville, where town lots give way to larger tracts. Roughly 29,815 people call Randolph County home (Census Bureau estimate, 2023) on some 575 square miles. Randolph County was formed in 1795, so old deeds can run back a long way.
