Augrented Insights Report for 21 Convent Avenue

21 Convent Avenue is a 5-story, 24-unit residential building constructed in 1920 and currently owned by Michael Faust. The building has experienced recurring maintenance issues over the past few years, with the most recent pattern of complaints emerging in late 2024, including concerns about flooring, safety (fire escape), door issues, electrical problems (no lighting), and missing signage. These recent complaints were generally found not to violate housing laws, though an inspector was unable to access one flooring complaint.

Separate maintenance issues have appeared regularly, including a slow water leak that persisted from September 2023 to May 2024, plumbing problems, and a potential heat/hot water issue in January 2023 where inspectors could not gain access to perform an inspection. The building has faced several significant violations in recent years, notably including an open violation from October 2024 regarding household items obstructing fire escapes, and a March 2024 violation related to self-closing doors at the roof bulkhead. Past records show multiple compliance issues, including pest control challenges with documented bedbug infestations across various periods, though all reported units were successfully treated.

Additionally, rodent inspections in 2023-2025 have shown mixed results, with repeated rat activity noted during inspections. The building's history also includes plumbing work without proper permits in 2018 and multiple safety-related concerns such as combustible material storage near gas meters. While some violations have been resolved, including a 2022 issue with Apartment 9's safety devices and window guard requirements, there remains an ongoing pattern of maintenance challenges that suggest persistent building system issues.
