394 East 21st Street, Brooklyn, NY 11226

394 East 21st Street is a 6-story, 53-unit apartment building in Flatbush, constructed in 1963 and currently owned by Adam Parkoff. The building has experienced recurring heat and hot water issues throughout 2025, with ten documented complaints between December 2024 and March 2025, most of which were classified as emergencies and involved the entire building.

While many of these complaints were resolved with heat and hot water restoration, the frequency of the outages suggests ongoing maintenance concerns. The building's elevator has been a significant area of focus, with multiple inspections and violations recorded between 2018 and 2025 for issues including inoperative position indicators, damaged lights, and release rollers, though recent inspections (most recently July 2025) found no violations warranting action. The property has also faced various maintenance challenges, including multiple Housing Maintenance Code violations identified in May 2023, such as broken ceramic tiles in Apartment 7E, fire retardant plaster issues in the 6th story public hall, and problems with the elevator mirror.

Apartment 6A had several violations identified in March 2023, including mold presence, carbon monoxide detector issues, and plumbing concerns, though most of these were certified as corrected by April 2023. The building's environmental compliance history shows generally good performance in pest management, with no reported bedbug infestations since 2020 and passing rodent inspections in 2019, 2022, and 2023, though a rat activity notice was recorded in October 2022. The property currently has an active DOB violation regarding the failure to display energy efficiency scores, issued in December 2024.
