Unlock complete reportThe two-unit residential building at 6211 W Diversey Ave in Belmont Cragin, owned by Robert J Mercado, has been experiencing ongoing regulatory and maintenance challenges since at least 2021. The property, constructed in 1920, currently has three open building code violations as of 2024, with one related to a periodic routine inspection and six others stemming from complaint-driven inspections conducted in November 2021. These open violations represent a significant concern, as they have remained unresolved for substantial periods. The building's service request history over the past seven years shows limited but concerning activity, including an open sign repair request as of April 2026, while three other service requests from 2024-2025 (including a fly dumping complaint and garbage cart maintenance issue) have been resolved. The property has accrued a total of 22 building violations and five 311 service requests in the past seven years, indicating ongoing challenges with building maintenance and responsiveness to resident needs. While the unit count and basic property details are straightforward, the primary focus for prospective tenants should be the pattern of unresolved building code violations and the timing of these inspection-related issues, which appears to have intensified starting in late 2021 and continuing into 2024.

How 6211 W Diversey 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.
Out of 4437 buildings in this neighborhood, 4304 are predicted to be safer.
