For any lot around Tiffin, the Coralville GIS map shows parcel boundaries plus basic tax data. This Coralville guide covers: which viewer to open, how to search it, and what to double-check with records.
Opening the Coralville GIS map: start here
Parcel maps here are usually run by the county, not the town, so for Coralville the go-to is the Johnson County Beacon site.
Opening the official parcel viewer
Go first to the Johnson County Beacon site; it includes each tax parcel around Oxford and Hills. When a rural tract has no street number, pan along US Route 218 until the lines appear, then click inside the one you want. For land near North Liberty, a pop-up or side panel normally shows the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
City limits and county records
Coralville sits in Johnson County, Iowa, which means parcel data comes from the county. For land near North Liberty, City or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the city limits toward Oxford often falls under county rules instead.
Recorded documents worth pulling
For anything that matters, get the recorded deed from the County Recorder; the parcel map near North Liberty only summarizes it. Older tracts around Iowa City can sit on several deeds, and a title company can sort it out on a real sale.
Search tips
Acreage around Oxford might not have a street number, so pan the aerial and click the lot. If you're looking near Tiffin, searching by parcel number never misses, and it's printed on tax bills.
When a parcel crosses a boundary
Johnson County touches Benton County, Cedar County, Iowa County, Linn County, and Louisa County, all with their own assessor records. A tract near the line by Solon may show up across two assessors' files, so check the neighboring map before you assume the acreage. For property near Solon, the Platbookmapper state page lists each neighboring county map across Iowa.
Taking the map into the field
The parcel map usually runs in a mobile browser, useful out on a road near Oxford, though signal can drop in rural spots. A printout of the tract near Oxford keeps working without signal.
A quick look at the area
Iowa City serves as the county seat, which is where the courthouse records live. You'll also find Tiffin, North Liberty, and Solon, where town lots give way to larger tracts. About 157,528 people live in Johnson County (Census estimate, 2023) across roughly 613 square miles. Johnson County dates to 1837, and some chains of title near Solon are long.

How land is described here
Iowa uses the Public Land Survey System, which means a tract near Hills is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Hills can be irregular. Keep the legal description for land near Solon for any title or survey request.
Which office to call
For assessment questions about property around Iowa City belong with the County Assessor, the office behind the parcel record. Zoning, permits and septic questions near Hills need the planning or permitting office, depending on whether the land is inside town limits.
Owner, value and acreage
If sale dates appear, they help gauge the market around Hills give a rough idea of values; an appraiser is the real authority.
When the map won't load
When the map won't open around Oxford, switch browsers or turn off pop-up blockers; links occasionally change, and our directory page keeps the current one.
Limits of the parcel data
Parcel lines are drawn for taxes, not measured on the ground, so the edge of a yard near North Liberty may sit several feet off the line on screen. For acreage around Solon, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Saving what you find
Save a screenshot of the lot near Tiffin and its record panel, so you have it when calling an office.
