When a deed near Seven Mile says lot and block, you'll need the Hamilton plat map to make sense of it. Covered here for Hamilton: where to request a copy, plat versus tax map, and what to look for on the sheet.
Tracking down the Hamilton plat map
For a lot in Hamilton, the deed or parcel record often names the subdivision and plat reference; bring that to the recorder's office or its online index.
Getting to the right map
Parcels around Millville can be looked up on the Butler County parcel viewer, which opens without registering. When a rural tract has no street number, pan along US Route 27 and select the outline. On ground around Millville, the record panel typically gives the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Legal descriptions in Ohio
Rural deeds near Fairfield commonly use metes-and-bounds descriptions, which trace the boundary call by call. Platted lots around Seven Mile refer to a recorded plat, which is simpler to follow. Copy the legal description from the record for the parcel near Millville when you talk to a surveyor.
Hamilton and the county around it
Hamilton is part of Butler County, Ohio, and the county assessor maps its lots. Hamilton is also the county seat, handy when you need recorded documents. For land near Jacksonburg, city or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Land beyond the town limits out by Trenton generally answers to county rules rather than the town's.
Taking the map into the field
Most viewers work in a phone browser, handy when you're parked on a road near Jacksonburg, though signal can drop in rural spots. A printout of the tract near Jacksonburg helps when you meet an owner or agent.
Who handles what
Recorded documents for a parcel near Jacksonburg sit in the index kept by the County Recorder, usually searchable by name or document number. Building or septic questions for a lot near Jacksonburg go to planning, building or health offices, town or county, depending on location.
Two different maps
The tax map on the Butler County parcel viewer is a summary, while the recorded plat is the legal document.
A quick look at the area
Hamilton is the county seat, which is where the courthouse records live. You'll also find New Miami, Fairfield, Millville, and Seven Mile, each with its own cluster of lots. Roughly 393,043 people call Butler County home (Census Bureau estimate, 2023) spread over some 467 square miles. Butler County was formed in 1803, and some chains of title near New Miami are long. Features like Great Miami River and Little Miami River are easy to spot when you zoom out from Millville.
Metes and bounds instead
Rural land near New Miami that was never subdivided is often described by metes and bounds or survey description; look for a recorded survey for land near Seven Mile.
Reading the plat sheet
Easements on the plat near New Miami limit where you can build or fence; read the notes on the sheet.
Backing up the map with records
Before you sign anything, get the recorded deed from the County Recorder; the parcel map near New Miami only summarizes it. Older tracts around Trenton may sit on a long string of deeds, and a title company can sort it out on a real sale.
Ordering the Hamilton plat map

When a plat changes
An amended plat may change lots around New Miami, so check for later filings; vacated streets or alleys also get recorded.
Neighboring parcel maps
Butler County meets Dearborn County, IN, Franklin County, IN, Union County, IN, Hamilton County, and Montgomery County; every one of them runs a separate parcel map. A tract near the line by Millville may show up across two assessors' files, so open the neighboring map too. On ground around Seven Mile, our state page links every neighboring county map for Ohio.
Before you lean on the lines
Parcel lines are drawn for taxes, not measured on the ground, so a fence near New Miami can sit a few yards off the line on screen. With a lot near Jacksonburg, owner names and values update on a schedule, so a deed recorded last month might lag behind.
