Unlock complete reportThe six-unit residential building at 335 W 31st Street in Chicago's Armour Square neighborhood is a 132-year-old property owned by ZHI LING LI. The building's record over the past seven years shows minimal structural or regulatory issues, with only one building code violation noted - a periodic routine inspection violation from September 2019 that remains unresolved as of the latest data. The property has generated ten 311 service requests during this period, with several of them clustered around infrastructure concerns in 2025. Most notably, there were two street light outage complaints in July and October 2025, while a street pothole issue was reported in March 2026. During the same year, there were also two sign repair requests - one of which remains open as of the latest record. An abandoned vehicle complaint from December 2025 was successfully resolved. While the frequency of recent service requests might suggest ongoing attention to the building's surroundings, it's important to note that the majority of these issues relate to street infrastructure and public signage rather than the building itself.

How 335 W 31St 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.
Out of 508 buildings in this neighborhood, 493 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
