Unlock complete reportThe property at 902 N California Ave in Humboldt Park is a 5-unit building constructed in 1905 and currently owned by Ana De Luna. The building's recorded history over the past seven years shows relatively few significant issues, with only one building code violation noted during a periodic routine inspection in April 2022 that remains unresolved. The property has generated a total of 30 service requests through the 311 system, while the owner has had 39 total service requests across three parcels. A notable cluster of service requests occurred in 2026, including multiple public infrastructure issues such as sewer problems, street lighting, and street water concerns, along with public space maintenance matters like graffiti removal and snow clearance. The building's record shows minimal permit activity, with only one building permit issued in the past seven years. While the number of service requests and violations is relatively low for a building of this age and size, the presence of an open building code violation and the range of maintenance and infrastructure issues reported through 311 services warrant attention.
How 902 N California 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
Grade A–B — Low risk
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Grade C — Moderate risk
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Grade D–F — High risk
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 6211 buildings in this neighborhood, 5776 are predicted to be safer.
