Unlock complete reportThe three-unit building at 4621 N Lawndale Ave in Albany Park, owned by Sebastian Wendolowski, was constructed in 1921 and has a minimal record of violations and service requests over the past seven years. Most notably, there were two building code violations recorded in March 2024, though both were promptly resolved. The property has generated 37 service requests through the 311 system during this period, with the most recent requests in 2026 primarily related to municipal services such as yard waste pick-up, recycling, and street maintenance issues including potholes. A single environmental complaint regarding asbestos was filed in October 2004, though no subsequent asbestos-related issues have been documented. While the building has had routine municipal service requests, the relatively low number of building violations and prompt resolution of any issues suggests basic regulatory compliance in recent years.

How 4621 N Lawndale 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.
