Unlock complete reportThe three-unit residential building at 2421 W Warner Ave in Chicago's North Center neighborhood, owned by Craig Deraedt, was constructed in 1913 and has had limited documented activity over the past several years. The most recent service request was filed in September 2025 regarding a nuisance animal complaint, which has since been resolved. Notably, there appears to have been a cluster of tree-related issues in the vicinity of the property, with three service requests concerning tree maintenance (two for trimming and one for removal inspection) and tree debris clean-up occurring between March and August 2024. Additionally, a blue recycling cart request was filed and addressed in July 2024. While the total of seven service requests over seven years might seem modest, the concentration of tree-related issues in 2024 suggests a period of particular attention to the property's external environment during that time. All documented service requests have been officially closed.

How 2421 W Warner 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 2652 buildings in this neighborhood, 1379 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
