Getting started with the Fairfield GIS map
Near Trenton, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
The viewer Butler County publishes
Go first to the Butler County parcel viewer; it includes every tax parcel from Millville to Seven Mile. Without an address in hand, follow US Route 27 on the aerial until the lines appear, then click inside the one you want. If the land is near Sharonville, a pop-up or side panel normally shows the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Using it on a phone
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Sharonville, though signal can drop in rural spots. A printout of the tract near Millville keeps working without signal.
Neighboring parcel maps
Butler County touches Dearborn County, IN, Franklin County, IN, Union County, IN, Hamilton County, and Montgomery County, and each of those keeps its own parcel map. Acreage along the edge near Sharonville can show up across two assessors' files, so look at the adjacent map before you assume the acreage.
