Unlock complete reportThe two-unit residential building at 9223 S Union Ave in Chicago's Washington Heights neighborhood, owned by Bertha Maury, has been standing since 1918. Over the past seven years, the building has generated a total of nine service requests, with the most recent activity occurring between late 2025 and early 2026. The majority of these requests (five out of nine) have been related to recycling pick-up services, indicating some level of inconsistency or need for clarification regarding waste management procedures in the area. Other reported issues include a nuisance animal complaint, an abandoned vehicle complaint, and a tree removal inspection request, though none of these incidents appear to have posed significant risks to resident safety or comfort. The oldest recorded service request was a general information call to the 311 system in October 2024, which provides no specific context about building conditions or services. While the volume of service requests is relatively low for a building of this age and size, the recent clustering of service requests in 2025-2026 suggests that these issues may have been concentrated in that time period, with no recorded service requests in 2027 to date.

How 9223 S Union 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 576 buildings in this neighborhood, 323 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
