AI summary

The two-unit residential building at 5134 W Belmont Ave in Portage Park, owned by Bogdan Gajo, has been in operation since 1956 and has experienced four documented 311 service requests over the past seven years. The most recent service request, submitted in December 2025, was for tree trimming, though it is worth noting that this particular request type is no longer being accepted by city services. Prior to this, the building faced several concerning issues in 2024, including a rodent infestation complaint in July, a tree removal inspection in May, and a sanitation code violation in March, all of which have been resolved and marked as closed. The pattern of service requests in 2024, particularly the rodent complaint and sanitation violation, may be of interest as they relate to building maintenance and resident comfort, though all recorded issues have been addressed through the city's service response system.

Risk rating

How 5134 W Belmont 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.
