Unlock complete reportThe three-unit residential building at 4755 N London Ave in Portage Park, owned by Maria M Mejia, has a documented history spanning over a century since its construction in 1915. The property currently has four unresolved building code violations that were all recorded as complaint-driven inspections in the fall of 2020 and October 2021, which represent the most significant outstanding compliance issues on record. These violations, which remain open, warrant particular attention as they may impact resident safety and comfort. In addition to these building code violations, the property has generated a substantial number of service requests over the past seven years, totaling 48 incidents. The most recent cluster of service requests occurred between April and May 2025, and all of these were related to parking enforcement matters, including vehicle sticker violations and parking code reviews, with all requests marked as closed. While the parking-related issues show some recent activity, they are primarily regulatory matters rather than concerns directly affecting the building's habitability or maintenance.

How 4755 N London 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.

Lower risk — safer than most nearby
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Typical — about average for the neighborhood
