Unlock complete reportThe three-unit residential building at 636 W 47th Place in Chicago's New City neighborhood, owned by WILLIAN KONCHAN, has been experiencing a notable cluster of issues in recent years. The most significant and pressing concerns are three unresolved building code violations as of September 2025, which were initiated through complaint-driven inspections. The property has also generated multiple 311 service requests over the past seven years, with the most recent being an open public way inspection request from May 2026. While some of these requests have been resolved—such as a building violation in August 2025, a 311 information call in May 2025, graffiti removal in March 2025, and an abandoned vehicle complaint in February 2025—there remains ongoing concern due to the concentration of recent violations and complaints. Notably, a rodent infestation issue was reported and closed in November 2024, which could suggest potential ongoing maintenance or sanitation challenges within the building or its vicinity. The property, built in 1888, has had three building violations and six 311 service requests recorded under the owner's name in the past seven years, with all listed violations and service requests occurring between 2024 and 2026.
How 636 W 47Th 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 4189 buildings in this neighborhood, 1340 are predicted to be safer.
