AI summary

The two-unit residential building at 6111 S Washtenaw Ave in the Chicago Lawn neighborhood, owned by Constantino Meza, has been documented since its construction in 1923. Over the past seven years, the building has generated a total of seven service requests through the city's 311 system. The most concerning pattern in recent requests is a cluster of water-related issues, with two basement water complaints filed in late August 2025, suggesting potential moisture or drainage challenges in the building's foundation or basement area. Other recent service requests include two separate garbage cart maintenance issues and a blue recycling cart request in September 2025, indicating some ongoing concerns with waste management facilities. The building's most recent documented issue was a tree trimming request from January 2026, though this particular request type is no longer being accepted. While the total number of complaints is relatively low for a century-old building, the concentration of water-related issues in mid-2025 stands out as the most significant concern in the building's recent history.

Risk rating

How 6111 S Washtenaw Ave 1'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.
