Initial analysis

The two-unit building at 620 E 90th Street in the Chatham neighborhood, built in 1893 and owned by Vestula Quarles, has a somewhat concerning recent history from 2016 to 2023. The most significant issue stems from four unresolved building code violations recorded in October 2021, which were categorized as complaint-driven inspections. While these violations remain open, it's important to note that there have been no new violations recorded in the past two years. The property has generated 13 service requests through the 311 system over the past seven years, with the most recent requests in 2026 primarily consisting of information calls, a water lead test kit request, and a blue recycling cart request - all of which were closed without indicating any ongoing issues. Prior to these recent requests, there were two vacant/abandoned building complaints recorded in November 2025, along with one abandoned vehicle complaint, all of which were subsequently closed. While the building has had its share of issues, particularly with the unresolved violations from 2021, the nature of the most recent 311 service requests suggests a shift in focus from pressing safety concerns to routine municipal services.

Risk rating

How 620 E 90Th St 1Fl'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.

Neighborhood percentile
22ndpercentile

Out of 1901 buildings in this neighborhood, 1483 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
