Initial analysis

The 12-unit residential building at 220 E 77th Street in Chicago's Grand Crossing neighborhood, owned by Marietta Lawson, has been standing since 1926. Over the past seven years, the property has generated a total of twelve 311 service requests, exhibiting a consistent pattern of environmental maintenance needs. The most recent incidents, all occurring in 2025, suggest ongoing challenges with tree management in the vicinity, with three separate reports of tree debris needing clean-up and one tree emergency that year. The property has also experienced issues with waste management, evidenced by a fly dumping complaint in June 2026 and an abandoned vehicle complaint in January 2026. Two waste removal requests - one for yard waste and another for general debris - were submitted in October 2025, indicating a recurring need for external clean-up services. While all reported issues have been marked as closed, the frequency and nature of these service requests suggest that the building's environment requires regular attention to maintain livability standards.

Risk rating

How 220 E 77Th 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.

Neighborhood percentile
7thpercentile
