Unlock complete reportThe two-unit residential building at 3427 W Wabansia Ave in Humboldt Park, owned by Chris Kellner, has experienced several notable events over the past few years. Most significantly, the property underwent multiple complaint-driven inspections in May 2025 that resulted in building code violations, though records indicate all of these violations were promptly complied with and resolved. The building's maintenance record includes various service requests to the city's 311 system over the past seven years, with the most recent activities in 2026 involving sanitation issues and tree-related concerns - a tree removal inspection remains open as of March 2026. Other service requests from 2025 that have been resolved include a garbage cart maintenance issue, a rodent baiting complaint, and a street light pole damage complaint, all of which suggest attention to basic infrastructure and pest management needs. While the property has experienced eight building violations and fourteen service requests in total over the past seven years, the prompt resolution of most issues indicates a generally responsive management approach to code compliance and resident concerns, with particular attention paid to sanitation and environmental maintenance matters.

How 3427 W Wabansia 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.
Out of 6229 buildings in this neighborhood, 62 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
