Unlock complete reportThe two-unit residential building at 624 E 91st Street in Chicago's Chatham neighborhood, owned by Michael J. Durham, was constructed in 1923 and has experienced minimal documented activity over the past seven years. The property's official records show only one building permit and two 311 service requests during this period, all of which were made in 2025, specifically relating to requests for water lead test kits. These water quality concerns appear to be the only significant events on record for this property, with both test kit requests remaining unresolved or "open" as of the most recent update. The building's permit and service request history suggest limited maintenance or modification activity in recent years, though the open nature of the lead testing requests indicates ongoing water safety monitoring efforts.

How 624 E 91St St 1'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 1901 buildings in this neighborhood, 456 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
