AI summary

The two-unit property at 6844 N Ottawa Ave in Edison Park, owned by Violeta DeLeon, is a 133-year-old residential building built in 1890. The building's record over the past seven years shows a concerning trend of service requests, with a notably high volume of 45 311 Service Requests, particularly in 2026 when multiple reports emerged in quick succession during April and June. Most recently, there have been three tree debris clean-up requests and one sidewalk inspection request that remain open, suggesting ongoing maintenance issues in the immediate surroundings. The property has also experienced some infrastructure challenges, evidenced by a water-in-basement complaint and a sewer cleaning inspection request from April 2026, though these issues were marked as closed. There is only one building permit on record for this property in the past seven years, which is relatively low for a structure of its age, and given the number of service requests, this might indicate deferred maintenance or a lack of proactive property improvements. The building's age and history of service requests merit attention to maintenance patterns and response times, though it should be noted that not all 311 Service Requests directly relate to the building's condition, as some pertain to public infrastructure like street lighting.

Risk rating

How 6844 N Ottawa 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.
