Chicago's inspector general says the city could be making more than $45,000 if it charged for 19 parking spots in a warehouse where city employees park for free.

The report notes the value of the property in the pricy River North neighborhood may exceed $1 million based on a similar recently-sold property a block away.

Rachel Leven is the spokeswoman for the inspector general's office. She says the office's staff also found that dozens of other city workers -- including 28 from the inspector general's office -- also park for free in the immediate area.

The report does not criticize the free parking, but says the city must evaluate all its property to determine if it is being used in the most economical and effective way.
