How Cook County is trying to improve its property assessments
The Cook County Assessor's Office is working on several fixes to improve the accuracy of property assessments.
Why it matters: Earlier this week, Axios reported that the office is using flawed data to create certain assessments and deny some appeals.
The big picture: Property tax appeals are a big deal in Cook County. Nationwide only about 5% of homeowners appeal their property taxes, but in Cook County that number jumps to 30%, per the Board of Review.
- The business of tax appeals is so prominent and potentially lucrative that two of the state's most powerful politicians — Mike Madigan and Ed Burke — chose tax appeal law as their other profession.
What's happening: CCAO chief of staff Scott Smith told Axios the agency is taking these steps to address issues with some assessments:
- Revising its permit collection and review process, "which will ensure we have up-to-date information on new construction."
- Implementing a new team to "review sales that seem inconsistent with characteristics or are not 'arm's length' (meaning a sale to a family member for a lower than market price)."
- Increasing field inspections, "which will confirm property characteristics and spot recent construction."
- Requesting access to a federal Universal Appraisal Database, "which offers better information on newer properties."
Yes, but: Smith can't say when these improvements will be implemented.
Reality check: Though still flawed, the accuracy of Cook County assessments has improved under Assessor Fritz Kaegi, according to University of Chicago researcher Chris Berry, who found high overassessment in low-income neighborhoods under Kaegi's predecessor Joe Berrios.
- "Some of the lower-priced properties were being assessed at [values] 25% or even 45% more than they were worth on the market, and that's almost entirely gone now in Cook County," Berry told Route 50 magazine.
- "I was really shocked when I saw the quality of the assessments coming out. I thought it could take much longer."
Of note: In 2021, state Sen. Emile Jones III introduced a bill that would allow property taxpayers to pay only a portion of their bill until they had exhausted all appeals and lost.
- Similar legislation has succeeded in other states, but it failed here.
