Initial analysis

The three-unit residential building at 9429 S Justine St in Washington Heights, owned by Archie Thompson, has been standing since 1926 and has experienced several notable events in recent years. Most concerning are two unresolved building code violations as of April 2024, both resulting from complaint-driven inspections. The property has also generated multiple service requests through the 311 system over the past seven years, with the most recent being a report of an injured animal in May 2026. Garbage cart maintenance has been a recurring issue, with three documented complaints in 2025 (July, October, and November). Other infrastructure concerns in 2025 included a street light outage in June and a tree emergency in the same month, both of which were resolved. While the building has maintained its basic structural integrity since 1926, the existence of open building code violations in 2024 warrants attention to ensure resident safety and compliance with current regulations.

Risk rating

How 9429 S Justine 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.

Neighborhood percentile
13thpercentile
