Humboldt Park, Chicago IL 60651 16034190220000 7 units · 1927

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 seven-unit building at 4203 W Walton in the Humboldt Park neighborhood is a 1927 structure currently owned by JAF920 LLC. Over the past seven years, the property has generated relatively few municipal service requests, with only 4 direct complaints or inquiries to 311 City Services, though the owner has filed a total of 10 requests including two tree planting requests and one abandoned vehicle complaint in 2024. The building's documented history shows minimal regulatory issues, with only one building violation recorded in the past seven years and just one building permit filed by the owner during this period. The most recent activity involves multiple requests for tree planting in May 2024, suggesting the property management is engaged in landscape improvements, along with an information-only call to 311 Services in June 2024. While the building's record is generally unremarkable with regard to service requests and violations, the limited data available represents only a portion of the ongoing property management activity.

Risk rating

How 4203 W Walton 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.

Neighborhood percentile
11thpercentile

Out of 6229 buildings in this neighborhood, 5544 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
