Unlock complete reportThe three-unit residential building at 3704 N Harlem Ave in the Dunning neighborhood, owned by Irene A Santos, has experienced several notable issues in recent years. Built in 1959, this property has accumulated a total of four building code violations over the past seven years, with the most recent unresolved violation recorded in March 2026, following another complaint-driven inspection in November 2024 that was eventually resolved. Particularly concerning are the two open violations from July 2019, which remain unresolved to date. The building has been subject to two permitted modifications during this period, though the specific nature of these permits is not detailed in the available records. While not all violations necessarily indicate immediate safety concerns, the combination of multiple unresolved issues, particularly the recent violation in 2026, suggests ongoing compliance challenges that may impact resident experience.

How 3704 N Harlem 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.
Out of 1070 buildings in this neighborhood, 942 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
