Unlock complete reportThe two-unit residential building at 8905 S Ada Street in Chicago's Washington Heights neighborhood, owned by Yanhong Kroeger, has a documented history dating back to its construction in 1903. The property has experienced several notable issues over the past three years, with a total of 12 service requests filed through the 311 system, five building violations on record, as well as three tree-related emergencies requiring attention in 2024 and 2025, including one case involving debris that necessitated clean-up services. The most recent service requests in April 2026 pertained to garbage cart maintenance and blue recycling cart issues, along with a missed garbage pick-up complaint in March 2026, suggesting some ongoing concerns with waste management services in the area. While the building's age (120+ years) is significant, the documented service issues primarily relate to environmental and waste management matters rather than structural or safety concerns, though the concentration of tree-related emergencies in 2024-2025 warrants attention.

How 8905 S Ada 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 576 buildings in this neighborhood, 248 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
