Initial analysis

The three-story residential building at 9811 S Throop St in Washington Heights, owned by Veronica Jamison, has been standing since 1929 and has recently generated notable municipal service activity. Over the past seven years, there have been 12 documented 311 service requests associated with the property, with the majority (seven out of twelve) occurring in 2025-2026. The most recent service requests, from 2026, are related to tree maintenance issues, including both debris clean-up and a removal inspection, which remain open as of October 2023. Prior to these, there were several sanitation-related requests in 2025, including completed tasks for garbage cart maintenance and blue recycling cart issues, as well as a closed request for dead animal removal in March 2026. The building's records show minimal permit activity, with only one building permit issued in the past seven years, suggesting limited recent structural modifications or improvements. While the property has experienced regular municipal service interactions, they primarily relate to external maintenance and sanitation matters rather than any internal building concerns.

Risk rating

How 9811 S Throop St's risk score is calculated

We trained a model on 7 years of Chicago code enforcement data — building violations, 311 complaint history, environmental enforcement, and owner track records. It estimates the probability that the City of Chicago will find a code violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Lower risk — safer than most nearby

City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.

Neighborhood percentile
94thpercentile
