670 4th Avenue, Brooklyn, NY 11232

The three-story, three-unit building at 670 4th Avenue in Sunset Park, owned by Mendy Bruner and constructed in 1910, has experienced several significant maintenance and compliance issues over recent years. The property has undergone an apparent conversion to Class A status, with the most recent notable concerns centered around bedbug reporting requirements.

While the building had violations in 2021 and 2022 related to failure to file annual bedbug reports (Class A violations), these issues appear to have been resolved as recent filings from 2023 through 2025 show no infested units, though there were instances of eradicated units noted in the 2025 filing. A major concern from 2017 remains unresolved, with two Class C violations still marked as open: one regarding the failure to post required heating system keyholder information in the first-story public hall, and another concerning the illegal installation of a key-operated double cylinder lock at the building entrance. Most recently, in August 2023, a complaint was filed regarding an alleged illegal conversion that was inspected in September 2024, but the inspector was unable to gain access during the final attempted inspection.

This unresolved complaint regarding building configuration raises potential safety and compliance concerns. The building's maintenance history shows periodic attention to pest management through bedbug reporting requirements, though there was a notable gap in compliance between 2017 and 2022 regarding timely reporting. The persistence of the 2017 violations related to building access and security infrastructure, despite being certified as corrected in November 2017, suggests historical challenges with building security measures that may warrant attention.
