Unlock complete reportThe two-unit residential building at 5843 W Peterson Ave in the Jefferson Park neighborhood, owned by Gregory Krowka, was constructed in 1924 and has had 26 documented 311 service requests over the past seven years. The most recent service requests from early 2026 indicate ongoing concerns with tree maintenance in the vicinity, with multiple tree trim requests submitted between January and August 2025-2026, though notably, these specific requests are no longer being accepted according to city guidelines. Additionally, there were two tree-related service requests in early 2026, including clean-up efforts for tree debris. The only water-related inquiry on record was a lead test kit request made in March 2026, though it's important to note that this request was subsequently closed. The service request history shows consistent engagement with municipal services, primarily focused on environmental maintenance, rather than any structural or safety concerns within the building itself.

How 5843 W Peterson Ave 1'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
