Unlock complete reportThe eight-unit residential building at 6730 N Northwest Chicago in Edison Park, owned by William P OConnell, has been in operation since 1921 and has experienced several significant events over the past seven years. The property has recorded five building violations and 12 service requests through the 311 system during this period, with the most concerning issues occurring in 2020 when multiple permit-related inspection violations were documented between February and June, though most were resolved except for two complaint-driven violations from May 11, 2020, that remain open and unresolved. More recent activity includes three 311 service requests in 2026, including building violation complaints and rodent issues, though the current status of these complaints as of the latest data is undetermined. The property has also generated two open requests for the Shared Cost Sidewalk Program in January 2026, suggesting potential infrastructure maintenance needs. Historical data shows a higher volume of service requests associated with the owner, totaling 25 across seven years, compared to the building's own request count of 12, indicating the owner manages multiple properties with varying service needs. While the building has had its share of violations and service requests, particularly during 2020, recent activity appears to be more focused on external infrastructure and pest control issues rather than building-specific violations, though the status of many recent requests remains open or undetermined.

How 6730 N Northwest Chicago'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 206 buildings in this neighborhood, 206 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
