Allen County Parcel Lookup

A public tool for looking up Allen County parcels — who owns them, what they're worth, when they changed hands, what district they're in, what's nearby. Built for residents first, no GIS software or Auditor's-office login required.

Use the Map to browse the county visually, or the Ownership Explorer to search by owner name, parcel ID, or address.

A second lens applies the same data to specific investigative questions about the BOSC/JSMC corridor in American and Shawnee Townships — see the Corridor Timeline and the Document Vault.

Status: alpha. The map renders Allen County's 52,730 parcels colored by owner category, with anomaly highlighting for out-of-state owners, recent transfers, and assessed-value outliers. The Ownership Explorer and other Tier 2 county connectors are in progress; the rest of Ohio is available at lower fidelity through the OGRIP statewide baseline.
