774 51st Street, Brooklyn, NY 11220

The 5-story, 6-unit residential building at 774 51st Street in Sunset Park, owned by Johnny Chen, was constructed in 2009 and has experienced several notable maintenance issues in recent years. Most concerning are three emergency safety complaints filed in October 2023 regarding carbon monoxide detector maintenance, smoke detector functionality, and broken window guard conditions - all of which were closed due to lack of access for inspection.

A non-emergency complaint regarding mailbox issues from December 2022 was also closed for similar reasons. The building has had some historical elevator compliance issues, with violations for failing to file required inspection documents in 2019, though these were ultimately dismissed in 2022.

Despite these maintenance challenges, the building has maintained an excellent bedbug-free record, with no infestations reported in any of the official filing periods from 2018 through 2025. The property was subject to a Vaccine Mandate Non-Compliance complaint in November 2021, regarding customer proof of vaccination checks, but this was handled promptly by the Department of Health. The building's most pressing current concerns center around the unaddressed safety issues from late 2023, particularly those involving essential safety systems like smoke and carbon monoxide detectors, though these were not inspected due to access issues rather than being resolved.
