Welcome to the Cook County Open Data Disseminator: Cuzmator
At Cuzmator, we write custom software around a process.
The Cook County Open Source Data Portal provides an essential service to our residents by preserving a clear and precise record of property information. The Open Source Files provide a permanent public record of the parcel transactions that involve assessed value over time, parcel sales over time, parcel appeals over time, and more.
Records maintained by the Cook County Government also document any outside interests that have a stake in a parcel of property, such as the mortgage held by a bank or the lien held by a company, government agency or neighborhood association.
The Cook County Open Source Data Portal is responsible for data presented on this site. Cuzmator, Onyx, and/or Cook County do NOT warrant this information to be 100% correct.
