Unlock complete reportThe three-unit residential building at 427 E 50th Street in the Grand Boulevard neighborhood, owned by Leslie Mimms, has a documented history dating back to its construction in 1898. Over the past seven years, the property has generated a relatively low number of service requests and permits, with only three 311 service requests recorded during this period. Among these, the most pressing current concern is an open building violation complaint filed in June 2026, which requires monitoring for resolution. The property has experienced some maintenance and health issues, including a rodent control complaint in May 2025 (which was subsequently closed) and a garbage cart maintenance issue in July 2024 (also closed). The building's permit activity is minimal, with just one permit recorded in the past seven years, though this alone is not necessarily indicative of any maintenance or structural concerns.

How 427 E 50Th 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 1174 buildings in this neighborhood, 517 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
