When a listing near Shueyville mentions a lot number, the Tiffin plat map is where those numbers come from. What this Tiffin guide covers: where plats are filed, plat versus tax map, and what to look for on the sheet.
Getting started with the Tiffin plat map
For a home near Iowa City, recorded plats sit with the County Recorder, usually in a plat book or cabinet.
Getting to the right map
Begin with the Johnson County Beacon site; it covers every assessed parcel in the county, Coralville included. For acreage around Swisher, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. For a home near Shueyville, the parcel card normally shows the owner of record, assessed acreage, a parcel ID and often a sale date.
Tiffin, IA: the basics
Tiffin lies within Johnson County, Iowa, which means parcel data comes from the county. For acreage around Coralville, City or town hall handles matters such as zoning, permits and utilities inside its limits, while the county keeps the tax map. Acreage past the city limits toward Iowa City usually falls under county rules instead.

About 157,528 people live in Johnson County (Census Bureau estimate, 2023) spread over about 613 square miles.

How a plat differs from the tax map

When there's no plat
Acreage around North Liberty outside a subdivision may have no plat at all; look for a recorded survey for land near Shueyville.
Getting answers from the right desk
For assessment questions about property around Oxford go to the County Assessor, which maintains the tax roll. Questions about what you can build around Oxford go to planning, building or health offices, depending on whether the land is inside town limits.
A word on accuracy
Listed acreage is an estimate; only a licensed surveyor can set the real boundary on land around Coralville. In and around Oxford, records update in batches, so a deed recorded last month might lag behind.
