Unlock complete reportThe four-unit residential building at 6420 N Campbell Ave in Chicago's West Ridge neighborhood, constructed in 1925 and currently owned by Campbell Restoration S, has experienced several concerning issues over the past seven years. Most notably, the property has accumulated six unresolved building code violations since February 2022, all resulting from complaint-driven inspections, which suggests ongoing compliance issues that have not been rectified. The building has also had four 311 service requests in this period, with the most recent being a tree trimming request in January 2026, followed by a garbage cart maintenance issue in October 2025, and a tree emergency in May 2025; the earliest recorded request was a standard information call to 311 in October 2024. While the 311 service requests appear to be routine maintenance matters that have been resolved, the persistent and unresolved nature of the building code violations is particularly notable, with five of the violations being clustered together in May 2022, and one additional violation from February 2022.

How 6420 N Campbell 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 3126 buildings in this neighborhood, 2813 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
