Unlock complete reportThe two-unit residential building at 3434 S Union Ave 2 in Chicago's Bridgeport neighborhood is a 134-year-old property constructed in 1889. The building's recent service request history spans the years 2024-2026 and reveals several significant events, with particular attention warranted to current water safety concerns. Most notably, there are two water lead test kit requests recorded in 2024 and 2025, with the latter request still showing as open. This indicates an ongoing concern about water quality that should be monitored closely. The property has experienced other maintenance issues, including a tree emergency in June 2026 (now closed) and an open tree debris clean-up request from June 2026, suggesting recent storm-related challenges. Additionally, there was a stray animal complaint in December 2025 that has since been resolved. While the total number of 311 service requests (five) over the past seven years is relatively low for a building of this age and size, the most pressing concerns appear to be focused on water safety and recent tree-related issues.

How 3434 S Union Ave 2's risk score is calculated
