For any lot around Pleasant Hill, a look at the Troy GIS map gives you parcel boundaries plus basic tax data. What this Troy guide covers: where that map lives, how to search it, and what to double-check with records.
Finding a lot on the Troy GIS map
On ground around Ludlow Falls, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Where the parcel data lives
Lots and tracts near Piqua appear on the Miami County ArcGIS parcel map, which opens without registering. Out toward West Milton, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. For property near Tipp City, the record panel normally shows the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Taking the map into the field
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Tipp City, so load it before you lose signal. A screenshot of the parcel near Casstown with its ID is a good backup.
Troy and the county around it
Troy is part of Miami County, Ohio, so its parcels are on the county's map. As the county seat, Troy hosts the courthouse, handy when you need recorded documents. For a tract near Pleasant Hill, City or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Lots just outside the city limits out by Casstown often falls under county rules, not municipal ones.

What the record panel tells you
