When a deed near Lower Salem says lot and block, look up the Marietta plat map it refers to. What this Marietta guide covers: where plats are filed, how a plat differs from a parcel map, and the details that matter to buyers.
Tracking down the Marietta plat map
For a subdivision near Matamoras, look for the plat book reference on the parcel record; use it to request a copy.
Opening the official parcel viewer
Go first to the Ohio Statewide Parcels layer in ArcGIS Map Viewer; it includes each assessed parcel around Belpre and Lower Salem. For a home near Lowell, type a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a tract near Matamoras, the record panel typically gives the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Marietta, OH: the basics
Marietta sits in Washington County, Ohio, so its parcels are on the county's map. As the county seat, Marietta hosts the courthouse, handy when you need recorded documents. Out toward Beverly, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Land beyond the city limits near Belpre often falls under county rules rather than the town's.
Getting answers from the right desk
If the acreage or value on a parcel near Lowell looks off belong with the County Auditor, since that office keeps the assessment data. Questions about what you can build around Matamoras need the planning or permitting office, depending on whether the land is inside town limits.
Limits of the parcel data
The acreage figure is an estimate; just a licensed surveyor establishes the real corners for a parcel near Macksburg. Out toward Belpre, records update in batches, so a deed recorded last month might lag behind.
Two different maps
If the tax map and plat differ near Lower Salem, go with the plat and a surveyor's work.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Beverly, but coverage can be spotty out of town. A screenshot of the parcel near Matamoras with its ID keeps working without signal.
Deeds, plats and who keeps them
When the details count, request the recorded deed from the County Recorder; the parcel map near Lower Salem only summarizes it. With a lot near Matamoras, have ready the document number shown in the record panel and the lookup takes minutes.
When a parcel crosses a boundary
Washington County touches Athens County, Monroe County, Morgan County, Noble County, and Pleasants County, WV, and each of those keeps its own parcel map. Ground near Lower Salem that runs to the line may show up in two county records, so check the neighboring map before you assume the acreage. For a home near Belpre, the Platbookmapper state page lists every bordering county map for Ohio.
Amended plats
An amended plat may change lots around Beverly, search the index for replats of the same subdivision; vacated streets or alleys also get recorded.
Getting your bearings

What a plat shows
