Chatham, Chicago IL 60619 25021050420000 2 units · 1888

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Initial analysis

The two-unit residential building at 836 E 89th St in Chatham, owned by Hattie M Williams, has a documented history dating back to 1888. Over the past seven years, there have been 14 service requests logged through the 311 system, with the most recent occurrences showing a concerning pattern of sanitation-related issues. In 2025 alone, there were multiple sanitation code violations reported in June, August, and November, along with a vacant/abandoned building complaint in November that merits attention. The building's 311 service requests also included a yard waste pick-up request in June 2025 and one "information only" call in August 2025. Of note, while the building has had one building permit issued in the past seven years, the frequency of sanitation-related complaints suggests ongoing maintenance or compliance challenges. The combined total of 14 service requests and only one building permit in the same period indicates relatively limited permitted work compared to the number of reported issues, though this should be contextualized within the routine nature of sanitation inspections and complaints.

Risk rating

How 836 E 89Th 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.
