Where the Iowa City GIS map lives
Closer to North Liberty, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Getting to the right map
Begin with the Johnson County Beacon site; it maps each tax parcel from North Liberty to Coralville. For a home near North Liberty, put in a street address, an owner's name or a parcel number, and the viewer zooms to the match. In and around Hills, the record panel normally shows the owner of record, assessed acreage, the parcel number and often a sale date.
Where the recorded documents are
Before you sign anything, pull the recorded deed from the County Recorder; the parcel map near Tiffin only summarizes it. Inherited tracts around North Liberty can go back through a long string of deeds, and a title company can sort it out before a purchase.
Saving what you find
Save a screenshot of the lot near North Liberty and its record panel, so you have it when calling an office.
Before you lean on the lines
Parcel lines are drawn for taxes, not surveyed, so the edge of a yard near Tiffin may sit a few yards off the line on screen. Near Solon, records update in batches, so a deed recorded last month might lag behind.
Reading the legal description
Iowa follows the Public Land Survey System, so deeds around North Liberty reference sections and townships. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near Solon can be irregular. Keep the legal description for land near Coralville for any title or survey request.

For acreage around North Liberty, 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. Lots just outside the town limits out by Lone Tree usually answers to county rules instead.
