A Madison County plat book is the township-by-township atlas farmers, hunters and land buyers around South Solon have kept in the truck for generations. We'll cover what's in one, where Madison County copies turn up, and how the county's free map fills the gaps.
How to use the Madison County plat book
A plat book, sometimes called a land atlas, lists each township in Madison County as a page, with ownership blocks labeled by owner name and rough acreage. Deeds and recorded plats, not the atlas, still govern land near Big Plain in the county.
Finding the tract on the Madison County map
There's no separate Madison County parcel site to hunt for; the Ohio Statewide Parcels layer in ArcGIS Map Viewer carries the county's parcels along with the rest of Ohio. Use the search box for an address in Midway or a parcel number, or simply zoom in and click a parcel near Plain City. If the official address for the Madison County, OH map ever changes, our directory page carries the current link for Midway and the rest of the county.
Towns and land across Madison County
From London, the seat of the county, the map spreads out to Dublin, Midway, Mount Sterling, and Plain City. Smaller places such as Choctaw Lake, Lafayette, and Plumwood appear on the Madison County map as little clusters of lots. Census Bureau estimates put Madison County at about 44,602 residents in 2023 on roughly 466 square miles of land. Platted neighborhoods near London give way to rural acreage elsewhere in the county. Madison County was organized in 1810, so deeds for older farms near Plain City can run back a long way.
Current and older editions
Private publishers have printed plat books for many rural counties, but editions for Madison County come and go; inquire at the courthouse, the extension office or a farm supply store in West Jefferson. An old atlas can help trace when a parcel near Mount Sterling split off from a larger farm.
Madison County land records
Deeds and plats behind the Madison County map are kept by the county's recording office; the official Madison County website names which office that is. In Ohio the county auditor, not an assessor, appraises real estate, so Madison County values come from the auditor's office on a six-year reappraisal cycle with an update in year three. Copy the parcel identifier and legal description from the county record before you request a deed for land near Dublin.
What a plat book page lists near London
A typical atlas page for a township near London lists sections, roads and streams, with each ownership block labeled. Owner names in an older Madison County edition may be decades out of date, so confirm on the county map before contacting anyone near Big Plain. For a land purchase near Dublin, rely on the county parcel record and a title search, not an atlas.
Old atlases and family history in Madison County
Names in an older Madison County atlas can lead you to the right deed in the grantor-grantee index for land near Big Plain. Saving PDFs of the county map around Big Plain gives you an offline reference when the signal drops.
The Madison County economy in brief
Madison County's 2022 business count was 733 establishments, with construction, retail trade, and other services the largest groups. Transportation equipment manufacturing and warehousing and storage make up an above-average share of Madison County businesses, a clue to how land around Dublin gets used.
Current owners without a printed book
The Ohio Statewide Parcels layer in ArcGIS Map Viewer works as a living Madison County plat book, with owner names and parcel lines over aerial photos of Madison County. Pair the county map with a road atlas for the back roads near Mount Sterling.
