Unlock complete reportThe four-unit residential building at 2631 S Shields Ave in Armour Square, constructed in 1878, is owned by Jian T Liang and Xue M M. The property has experienced several notable service issues in the first half of 2026, with three separate incidents of low water pressure reported in March 2026, followed by a water-in-basement complaint in April 2026, suggesting potential ongoing water infrastructure challenges. The building has also faced pest control issues, with rodent complaints filed in both February and October 2025, though these appear to have been addressed through the appropriate city services. While the building has a relatively low total of 12 service requests on record over the past seven years, the concentration of water-related complaints in early 2026, particularly affecting multiple units, represents the most significant pattern of service issues in recent memory.

How 2631 S Shields 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
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Grade D–F — High risk
