Initial analysis

The two-unit residential building at 839 W Lill Ave, located in the Sheffield & DePaul neighborhood and owned by G Albihero M Zampar, has been standing since 1898. The property has experienced several notable issues in recent years, with a particular concentration of service requests in 2026. This year alone, there have been multiple requests for yard waste pick-up (three instances) and two rodent-related complaints between January and March. The building's environmental enforcement record reveals two significant construction-related violations from December 2022, both concerning construction site cleanliness, for which the owner was fined $750 each, resulting in a total penalty of $1,500. While the total number of 311 service requests over the past seven years stands at 31, it's worth noting that the majority of these recent complaints relate to external factors (yard waste and rodent issues) rather than building-specific problems, though they do impact resident quality of life. The property has maintained compliance with building codes following the construction site violations, as there have been no further environmental enforcement actions recorded in the past year.

Risk rating

How 839 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.
