Unlock complete reportThe two-unit, three-story residential building at 8241 S Buffalo Ave in Chicago's South Chicago neighborhood is a century-old property owned by Jose A Perez. The building's recent history (last seven years) shows a concerning pattern of unresolved issues, particularly notable are six open violations from March 2022, all resulting from complaint-driven inspections. While several violations from the same date were resolved, the presence of multiple ongoing violations raises concerns about the overall maintenance and compliance status of the property. The 311 service requests over the past seven years indicate significant resident concerns, with 21 total requests logged for this single address, including a recent water lead test kit request from March 2026 that remains open, and multiple nuisance animal complaints (2025) including one about a vicious animal. The building's records also show a history of pest control issues, with a rat/rodent complaint filed in September 2025, and other maintenance concerns such as weed removal requests. The property has generated considerable 311 service activity under its current ownership, with 51 service requests recorded across five parcels, though only one building permit has been filed during this period, suggesting limited proactive property improvements.

How 8241 S Buffalo Ave's risk score is calculated
