Where the parcel data comes from
It is a county-level map: Lyon County or the company it hires keeps the parcel layer up to date. When we checked in October 2026, the map page on this site was limited to signed-in users. Other parts of the site may be open, and the county office can explain how access works.
How to use the Lyon County viewer
- Open the link to the county's qPublic site, run by Schneider Geospatial. Accept the disclaimer if one appears.
- Pick a search type from the menu (owner, street address or parcel ID), or go straight to the map page.
- Click a parcel and open its report for assessment, sales and building details where available.
- Use the map's layer list to add aerials or other layers.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.
