Unlock complete reportThe two-unit residential building at 4640 S Avers Ave in Chicago's Archer Heights neighborhood, owned by Linda Liu and constructed in 1971, has experienced several notable incidents over the past seven years, with the most significant cluster of issues occurring in 2025. During that year, the property had documented problems including a water in basement complaint in August, a rodent baiting/rat complaint in October, and two parking code enforcement reviews in January and November. The building's record shows a total of 15 service requests to 311 over the past seven years, with the most recent being an information-only call in February 2026. While the number of 311 calls is relatively moderate for a multi-unit residential building, the concentration of infrastructure-related issues in 2025, specifically the water problem and rodent complaint, may be of particular note when considering the building's maintenance history.

How 4640 S Avers 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
