Unlock complete reportThe 8-unit residential building at 7831 S Colfax in Chicago's South Shore neighborhood, owned by Paper St. Group, was constructed in 1905 and has experienced several significant events in recent years. Most notably, there are currently seven unresolved building code violations dated December 11, 2025, all related to periodic routine inspections, which suggest ongoing regulatory compliance concerns. The building has accumulated a total of 24 building code violations over the past seven years, indicating a pattern of regulatory infractions. In terms of service requests, there have been four documented 311 calls in 2025 alone, including a water lead test visit request in September, a building violation report in August, and two other incidents - one involving an injured animal and an information-only call - that were all subsequently closed. The property has had minimal construction activity during this period, with only two building permits issued in the past seven years. The concentration of recent violations and service requests, particularly the open building code violations, suggests potential ongoing maintenance and compliance challenges within the property.

How 7831 S Colfax Chicago'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
