Who runs this map
This is a statewide map, not a county site. NYS Tax Parcels Public layer (ArcGIS Map Viewer) covers parcels across New York, and Lewis County is one part of it. Statewide parcel layers are usually stitched together from county files, so the newest splits or sales may show up on the county's own records first. As of our October 2026 test, anyone could open it without signing in or paying.
