Unlock complete reportThe three-unit residential building at 1123 S Mason Ave in Chicago's Austin neighborhood, owned by Chanterial Eiland, has been part of the city's housing landscape since 1917. The building's recent history shows some concerning patterns, particularly in late 2022 when two complaint-driven inspections were initiated that remain unresolved as of October 2023. The property's service record includes multiple health and safety-related issues, with three documented rodent-related complaints (September 2024, September 2025, and one most recently in March 2026), suggesting an ongoing pest control challenge in the area. Additionally, there was a request for dead animal pickup in September 2024 and a street cleaning complaint in March 2025, both of which have been resolved. A tree trimming request was submitted in March 2026, though this particular request type is no longer being accepted by the city. While the building's violation and service request record over the past seven years is not excessively long, the nature of the complaints—particularly the unresolved building code violations and recurring rodent issues—warrants attention to the property's ongoing maintenance and pest control challenges.
