Augrented Insights Report for 50 East 21st Street

50 East 21st Street is a 6-story, 59-unit residential building in Flatbush, constructed in 1936 and currently owned by Barry Rudofsky. The building has faced recurring heat and hot water issues throughout 2024-2025, with at least 10 documented complaints between December 2024 and April 2025, most of which were resolved but indicate an ongoing maintenance challenge. The building has also experienced mechanical and structural concerns, particularly with its elevator system, as evidenced by multiple Department of Buildings complaints regarding single-device service with no alternate options, with the most recent complaints entered in January 2025.

An active violation regarding the FISP Cycle 9C Technical Report filing from February 2024 remains open. Recent inspections have revealed rodent activity in late 2023 and early 2024, with multiple rodent baiting treatments applied through the city's pest control program. Two specific apartments (4E and 6H) were noted for rodent and cockroach infestations in late 2024, though these violations were certified as corrected by early 2025.

The building's maintenance history also reveals several infrastructure issues, including problems with self-closing doors and latch sets in the compactor closet and vestibule areas, along with various other minor violations. Historical records show past structural concerns with the retaining wall, which was documented in multiple DOB violations between 2018-2019, though these were ultimately resolved. The building's elevator system has been a persistent concern, with multiple ECB violations regarding improper installation of door lock monitoring systems and other elevator-related issues between 2018-2020, suggesting ongoing maintenance challenges with this critical building system.
