About the official source
This map is published by or for Iowa County itself, so it reflects the local parcel layer rather than a third-party copy. Our October 2026 check found the map open to the public, with no account or payment needed.
Finding a property on this map
- Open the link to the Beacon site from Schneider Geospatial. If a terms or disclaimer window appears, agree to it to continue.
- Use the search bar to look up a street address, an owner's name or a parcel ID. Beacon sites usually also have a dedicated property search page.
- Click a lot on the map and then open its report for assessment and property details.
- Use the layer and basemap controls to add aerial photos or other layers the county publishes.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.

Maps vs. surveys
Online parcel lines are drawn for tax and planning use. They can be off by several feet, so use a recorded plat or a licensed surveyor for fences, setbacks or a sale.
