Unlock complete reportThe three-unit building at 3107 N Southport Ave, located in Chicago's Lake View neighborhood, is a 143-year-old structure owned by John C Willis. The property's recent history shows a concerning pattern, with three unresolved complaint-driven inspection violations recorded in February 2026, representing the first building code violations logged in the past seven years. The property has generated multiple 311 service requests over this period, totaling 15 requests under the owner's name, with the most recent being related to an open tree planting request from June 2025. Between September 2025 and May 2026, there were four graffiti removal requests and one public way inspection request, all of which have been closed. While the building appears to have had minimal documented violations prior to 2026, the recent cluster of complaint-driven inspections and unresolved violations suggests emerging maintenance or safety concerns that merit attention.

How 3107 N Southport Ave 2Nd'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.
