Where the parcel data lives

Around Cove, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. If the land is near Imbler, a pop-up or side panel usually lists the owner of record, assessed acreage, the parcel number and sometimes recent sales.
A quick look at the area

Around 25,944 people call Union County home (Census estimate, 2023) across roughly 2,037 square miles. Union County was formed in 1864, so old deeds can run back a long way.
Recorded documents worth pulling
