RPIE
The Cook County Assessor's Office collects Real Property Income & Expense (RPIE) data to collect characteristics, income, expense, and vacancy data to contribute to fair and accurate valuation of commercial properties.
RPIE 2.0 was released in 2024 and is now incorporated with the commercial or apartment appeal filing in SmartFile.
