Unlock complete reportThe 2-unit residential building at 11820 S Princeton Ave in West Pullman, owned by Julian Mickelson, has been standing since 1898 and has experienced several notable incidents in recent years. Most concerning are the two active water quality issues, with one water lead test kit request and an associated visit in October 2025 being recorded, though one of these has been marked as closed. The property has also faced rodent issues, with two rat complaints in 2025, both of which were resolved according to city records. More recently, in March 2026, there is an open violation regarding building permits and construction work that remains unresolved. Over the past seven years, the total number of service requests associated with the owner amounts to 65, including two environmental complaints, representing a significant level of interaction with city services. While the building's age and history are notable, the recent pattern of service requests suggests ongoing maintenance and compliance challenges that may affect resident experience.

How 11820 S Princeton Ave'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
Grade A–B — Low risk
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Grade C — Moderate risk
