Unlock complete reportThe six-unit residential building at 724 W 31st St in Chicago's Bridgeport neighborhood, owned by Zhao Hui Li, has a notable history since its construction in 1886. The most pressing current concern involves unresolved periodic routine inspection violations from December 2019, with six open violations officially recorded. While these are not recent compared to the current date, their unresolved status still warrants attention. The building has had relatively few documented problems over the past seven years, with a total of eight building violations and 30 service requests from the owner. Most of the recent activity involves maintenance and upkeep matters, with the majority of service requests in 2025-2026 focusing on tree trimming and vacant lot cleaning (four requests in total), as well as two instances of graffiti removal in December 2025. An environmental complaint related to service stations/storage tanks was recorded in 2014 but was resolved promptly by February 2014. The building's documented history suggests regular maintenance needs typical of an older structure, with particular attention required to address the outstanding inspection violations from 2019.

How 724 W 31St St's risk score is calculated
