When a deed near Butlerville says lot and block, look up the Mason plat map it refers to. Covered here for Mason: where plats are filed, plat versus tax map, and what to look for on the sheet.
Getting started with the Mason plat map
For a subdivision near Maineville, the deed or parcel record often names the subdivision and plat reference; that makes the request quick.
Opening the official parcel viewer
Begin with the Ohio Statewide Parcels layer in ArcGIS Map Viewer; it includes every tax parcel around Pleasant Plain and Maineville. For a tract near Maineville, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. For acreage around Butlerville, a pop-up or side panel usually lists the owner of record, assessed acreage, a parcel ID and often a sale date.
When there's no plat
Rural land near Pleasant Plain that was never subdivided is often described by metes and bounds or survey description; look for a recorded survey for land near South Lebanon.
Mason, OH: the basics
Mason is part of Warren County, Ohio, so its parcels are on the county's map. For acreage around South Lebanon, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the town limits toward Maineville generally follows county rules instead.
Places you'll see on the map
Lebanon holds the county offices, home to the main records offices. Smaller places on the map include South Lebanon, Maineville, and Morrow, where town lots give way to larger tracts. About 252,148 people call Warren County home (Census estimate, 2023) on some 401 square miles. Warren County was formed in 1803, which matters when you trace an old farm's title.
Deeds, plats and who keeps them
The map is an index, not the title: deeds, plats and easements for land near Maineville are kept by the County Recorder. Near Maineville, have ready the document number from the tax record to skip a name search.
How a plat differs from the tax map
The Ohio Statewide Parcels layer in ArcGIS Map Viewer draws parcels for taxes, but the recorded plat is what the deed relies on.
A word on accuracy
Acreage on the record is an assessed number; only a licensed surveyor sets the real boundary on land around Lebanon. In and around Butlerville, records update in batches, so a deed recorded last month might lag behind.
Next door to Warren County
Warren County meets Butler County, Clermont County, Clinton County, Greene County, and Hamilton County, all with their own assessor records. Ground near South Lebanon that runs to the line can be split across two assessors' files, so check the neighboring map as well. For property near Butlerville, our state page lists each bordering county map across Ohio.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Morrow, though signal can drop in rural spots. A screenshot of the parcel near Maineville with its ID is a good backup.
Which office to call
Questions about value or the owner field for land near Maineville belong with the County Auditor, the office behind the parcel record. Building or septic questions for a lot near Morrow need the planning or permitting office, town or county, depending on location.
Reading the plat sheet
Easements on the plat near Morrow can block a shed or pool; check the plat notes and any covenants.
Requesting the plat
For a home near Morrow, many recorder offices offer an online index, otherwise call or visit with the reference; small fees are common.
Reading the legal description
Tracts outside towns near South Lebanon are often described by metes and bounds, listing bearings, distances and landmarks. Subdivision lots in Pleasant Plain are typically described by lot and block, which is simpler to follow. Copy the legal description from the record for the parcel near Butlerville for any title or survey request.
Replats and vacations
Lots near Pleasant Plain can be combined or reconfigured by a replat, so check for later filings; vacated streets or alleys also get recorded.

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.
