Initial analysis

The two-unit residential building at 1628 S Hamlin Ave in Chicago's North Lawndale neighborhood is a 1902 structure currently owned by William B Sullivan, who owns two parcels associated with the property. The building's recent history shows minimal service requests, with only one 311 service request recorded in the past seven years, specifically related to a tree emergency in October 2025. This request, which has since been closed, is the only documented service call to the city's 311 system for this property in the most recent seven-year period, suggesting relatively stable building conditions with few reported issues. While the 311 service request system provides some insight into building concerns, it's important to note that not all building issues may be captured in these records.

Risk rating

How 1628 S Hamlin Ave'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.
