Unlock complete reportThe four-unit residential building at 1229 N Bosworth Avenue in the West Town neighborhood is a 132-year-old property currently owned by Jerzy Ptak, who also holds two parcels of land associated with this address. The building's recent service request history from the past seven years shows minimal issues, with only one building violation recorded during this period. The majority of the documented service requests are infrastructure-related, including a pothole complaint in June 2024 and a tree planting request in October 2025, both of which were resolved. Notably, there was a water lead test kit request made in October 2024 that was also closed, suggesting proactive measures were taken to address potential water quality concerns. The overall service request and violation record for the past seven years appears relatively clean, with a total of 17 service requests logged under the owner's name, though most of these interactions do not directly pertain to the building's condition or habitability.

How 1229 N Bosworth 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.
