Unlock complete reportThe three-unit residential building at 731 N Christiana Ave in Humboldt Park, constructed in 1908 and currently owned by Z Financial IL G Prop, has a concerning pattern of unresolved building code violations and service requests over recent years. The most recent cluster of complaint-driven inspection violations was recorded in January 2026, with three open violations that remain unresolved. Prior to this, on August 12, 2021, there were also three open complaint-driven inspection violations that have not been resolved. The building's record shows a total of six building violations within the past seven years, though this figure appears to underrepresent the problem when considering the owner's total of 41 violations across five parcels during the same period. The property has generated 30 total service requests under this ownership, with two 311 service requests specifically related to city services in January 2026, including a plumbing violation that has since been closed. The building's permit activity is notably minimal, with only one permit recorded in the past seven years, which may suggest limited maintenance or improvement work being conducted on the property.

How 731 N Christiana 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, 5980 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
