Where the parcel data comes from
This is a statewide map, not a county site. NJ Parcels and MOD-IV Composite layer (ArcGIS Map Viewer) covers parcels across New Jersey, and Passaic County is one part of it. Because a state agency compiles this layer from local data, check with the Passaic County assessor or recorder before relying on a recent change. When we tested the link in October 2026 it opened with no login and no fee.
