Unlock complete reportThe two-unit residential building at 3138 W Walton Street in Humboldt Park, owned by Leslie Perez Ribot, has a significant number of recent service requests on record, with particular attention to 2026 showing multiple ongoing concerns. Of particular note are two open service requests from April 2026: a vacant/abandoned building complaint and a building violation, suggesting possible property maintenance or occupancy issues. The property has also had recurring pest management needs, with two rodent-related complaints recorded in early 2026, though these were successfully resolved according to their closed status. Additionally, there have been multiple tree-related service requests in 2026, including an emergency situation (still open) and a planting request (closed). While the building's history shows it was constructed in 1920 and has had minimal documented service requests in previous years (totaling 23 over the past seven years), the recent clustering of service requests in 2026 indicates a period of particular activity regarding building maintenance and surrounding infrastructure.

How 3138 W Walton St'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

Out of 6229 buildings in this neighborhood, 1308 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
