If a legal description for land in Effingham cites a lot number, the Effingham plat map is where those numbers come from. What this Effingham guide covers: where plats are filed, plat versus tax map, and what to look for on the sheet.
Tracking down the Effingham plat map
For a subdivision near Altamont, the deed or parcel record often names the subdivision and plat reference; use it to request a copy.
Getting to the right map
The official parcel map for this area is the Effingham County ArcGIS parcel map, and anyone can open it without signing up. Closer to Mason, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. Closer to Teutopolis, the record panel usually lists the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
City limits and county records
Effingham sits in Effingham County, Illinois, so its parcels are on the county's map. As the county seat, Effingham hosts the courthouse, which puts the county Recorder of Deeds (in many counties the County Clerk and Recorder) close by. For a tract near Watson, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Acreage past the town limits toward Mason often follows county rules instead.
Where the recorded documents are
When the details count, get the recorded deed through the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Teutopolis only summarizes it. Long-held tracts around Teutopolis may sit on several deeds, so a title company is worth hiring if money is changing hands.
Before you lean on the lines
Acreage on the record is a tax-roll number; only a licensed surveyor can set the real boundary on land around Shumway. For a tract near Shumway, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Amended plats
An amended plat may change lots around Dieterich, search the index for replats of the same subdivision; street vacations near Mason show up in the records too.
Neighboring parcel maps
Effingham County touches Clay County, Cumberland County, Fayette County, Jasper County, and Shelby County, and each of those keeps its own parcel map. Ground near Dieterich that runs to the line can show up across two assessors' files, so open the neighboring map as well. With a lot near Watson, our state page lists every bordering county map for Illinois.
Which office to call
For assessment questions about property around Shumway belong with the Supervisor of Assessments, working with township assessors, since that office keeps the assessment data. Questions about what you can build around Dieterich go to planning, building or health offices, and the answer depends on jurisdiction.
Metes and bounds instead
Rural land near Altamont that was never subdivided may have no plat at all; look for a recorded survey for land near Teutopolis.
Recorded plat or GIS layer
The tax map on the Effingham County ArcGIS parcel map is a summary, but the recorded plat is what the deed relies on.
Effingham County in a few facts

Easements on the plat near Shumway can block a shed or pool; read the notes on the sheet.
Using it on a phone
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Watson, though signal can drop in rural spots. A screenshot of the parcel near Mason with its ID helps when you meet an owner or agent.
Reading the legal description
Illinois uses the Public Land Survey System, which means a tract near Shumway is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Watson odd-sized. Copy the legal description from the record for the parcel near Shumway when you talk to a surveyor.
Online indexes and office visits
For land near Teutopolis, some counties put plat images online, while others require a visit or a request; small fees are common.

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.
