Near South Side, Chicago IL 60605 17221020240000 454 units · 2006

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. 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 building at 1255 S Michigan in Chicago's Near South Side, managed by Forest City Tax Department, is a 454-unit residential property constructed in 2006. Over the past seven years, the property has generated a total of 128 service requests and required 23 building permits, showing relatively active engagement with city services and infrastructure maintenance. Recent records from 2025-2026 indicate several customer service interactions, including feedback on taxi services, a consumer fraud complaint, and a parking code enforcement review. Of particular note is an open water lead test kit request from December 2025, which warrants attention as it relates to resident health and safety. The building's service request history shows a pattern of varied issues being reported, though many appear to be routine inquiries or informational calls. While the property has maintained regular communication with city services, the presence of a lead test kit request suggests potential water quality concerns that may need monitoring as this situation develops.

Risk rating

How 1255 S Michigan Chicago'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.
