Unlock complete reportThe three-unit residential building at 3126 W 40th Place in Brighton Park, owned by Juan P Ascencio, is a century-old property constructed in 1916. The building's recent service history, spanning seven years, shows relatively minimal activity with only six 311 service requests on record. The most recent requests, from January 2026, involved parking code enforcement reviews, though the specific outcomes or concerns are not detailed in the records. Prior to these, there was one informational call to 311 in late January 2026. Looking back through the records, there were two related tree management issues in July 2024 - one concerning tree removal inspection and another involving tree debris clean-up - both of which were addressed and closed. The only other recorded service request during this period was a pet wellness check in November 2025. The overall low frequency of service requests over this extended period, combined with the diverse nature of the issues (from tree management to parking enforcement), suggests that there are no persistent or recurring problems affecting the building or its vicinity.

How 3126 W 40Th Pl'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 3956 buildings in this neighborhood, 1859 are predicted to be safer.
