The Assessor's Office has a Public Data Set which is comprised of three files with detailed information on each parcel in the city. This set of files contains: address/legal description data, land and building characteristics, ownership information, an assessment history, and a transfer history. The public data set is exported in delimited text file format.
This data set can be accessed free of charge at the following location: COR Public Data. Note: Google Chrome no longer supports FTP. Please use Microsoft Edge.
The Assessor's Office does not make custom databases or queries. The data is provided as is and is updated the first month of each quarter.
