AI summary

The two-unit residential building at 3745 W Belden Ave in Logan Square, owned by Regilio Perez, is a century-old property constructed in 1911. The building has experienced several administrative interactions over the past seven years, with six building code violations recorded, all of which were resolved through complaint-driven inspections conducted on July 11, 2022. These violations, while notable, were promptly addressed according to official records. The building's recent service request history shows two relatively minor municipal interactions in 2025: one concerning a blue recycling cart and another related to a sign repair, both of which have been closed. The property has only one building permit on record in the past seven years, which raises questions about the extent of any recent maintenance or improvements, though this could be typical for a well-maintained older building.

Risk rating

How 3745 W Belden 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.
