Property Tax Assessment

Searches county assessor records by address or parcel ID for owner, assessed value, and property details.

Overview

Searches county assessor records by address or parcel ID for owner, assessed value, and property details. Covers open-data assessor datasets including NYC PLUTO, SF Assessor Roll, and Cook County (Chicago); search by street address or parcel/BBL/APN identifier. Returns parcel id, owner, assessed and market value, building area (sqft), lot size, year built, zoning code, and a permalink to the source open-data portal. Open-data, CC0-licensed sources only; no proprietary commercial assessor feed. Use it as a property tax assessor lookup, parcel record search, owner-name lookup, lot-and-block lookup, or a zoning + sqft + year-built check for real-estate due diligence.
