Unlock complete reportThe two-unit residential building at 121 W 109th Street in Roseland, owned by Marcus Thomas, dates back to 1903 and has experienced several notable incidents in recent years. Most concerning are three unresolved complaint-driven violations recorded in May 2025, which represent the only building code violations on record in the past seven years. While there have been no building code violations reported since that date, the presence of three open violations warrants attention. The property has generated a total of 14 service requests through the 311 system over the past seven years, with the majority of recent requests in 2025-2026 relating to waste management and recycling services. This includes three blue recycling cart requests and one garbage cart maintenance request between January and February 2026, as well as a fly dumping complaint in January 2026. Earlier service requests also include a tree emergency in December 2025, which was resolved. The building's violation and service request history suggests ongoing maintenance and compliance challenges, though many of the recent 311 requests pertain to routine municipal service matters rather than building-specific issues.

How 121 W 109Th 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 1649 buildings in this neighborhood, 577 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
