Unlock complete reportThe six-unit residential building at 5900 W Gunnison St in Jefferson Park, owned by Elisabeth Iwan, has experienced some notable recent activity, particularly in August 2023 when two complaint-driven inspections resulted in open violations that remain unresolved as of October 2023. The building, constructed in 1968, has had a relatively low number of documented issues over the past seven years, with only two building code violations and three 311 service requests reaching the city's records. The 311 service requests, while now resolved, indicate some level of routine maintenance and neighborhood issues around the property, including a street light outage in May 2026, a rodent baiting complaint in November 2025, and a tree debris cleanup request in May 2025. The most pressing current concern appears to be the recent building code violations from August 2023, which warrant attention as they are still marked as unresolved in the city's database.

How 5900 W Gunnison St'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 1632 buildings in this neighborhood, 1501 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
