Initial analysis

The three-unit residential building at 1128 W Lill Avenue, located in the Sheffield & DePaul neighborhood and owned by Stephen Lin, is a 1893 structure that has experienced a range of maintenance and service issues over the past several years. The property has generated 15 documented 311 service requests in the last seven years, with the most recent concerns in 2026 including an open consumer fraud complaint and a closed pothole complaint. The building's maintenance history shows multiple tree-related issues in mid-2025, including emergency response and debris cleanup, along with a sewer cleaning inspection request. The property has also encountered some regulatory scrutiny, with two administrative violations recorded in May 2005 relating to code violations under sections 11-4-770 and 13-32-125 (2A), each resulting in $800 fines. While the building has had relatively few 311 service requests and building violations overall (15 and 5 respectively in the past seven years), the environmental enforcement cases from 2005 suggest a period of regulatory attention during that time. The recent pattern of service requests appears to be more focused on external infrastructure issues rather than building-specific problems, though the single building permit issued in the past seven years may indicate limited recent physical improvements to the structure itself.

Risk rating

How 1128 W Lill 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

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
