Humboldt Park, Chicago IL 60647 16021070010000 8 units · 1908

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Initial analysis

The 8-unit residential building at 3625 W North Chicago in the Humboldt Park neighborhood, owned by B & L Vasquez 3625, has a notably concerning pattern of water-related issues emerging in early 2026, with five water-related complaints registered between March 2nd and March 12th, including multiple basement water incidents and a leakage check request. This pattern of moisture-related problems constitutes the most significant ongoing maintenance challenge for the property, now comprising nearly one-third of the total documented service requests for the past seven years. The building, constructed in 1908, has a relatively small total of 18 service requests on record over the past seven years, with the majority of these being processed through the Chicago 311 system. Notably, these water-related incidents have occurred in close succession within a two-week period, with one related service request still showing as open at the time of this report. While the building has maintained some level of responsiveness to service requests, with most of the past issues being marked as resolved, the recent cluster of water-related problems suggests a potentially developing pattern of moisture management challenges affecting resident experience and property maintenance.

Risk rating

How 3625 W North 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.
