5802 4th Avenue, Brooklyn, NY 11220

The three-story, four-unit tenement building at 5802 4th Avenue in Sunset Park, owned by Yifeng Liang and built in 1922, has an extensive history of maintenance and safety compliance issues, particularly regarding life safety systems. Between 2005-2018, the building experienced multiple violations related to fire safety, including problems with smoke detectors, carbon monoxide detectors, and fire escape access. Most recently, the building has undergone annual inspections regarding bedbug reporting compliance from 2021-2024, with no reported infestations in the most recent four filings, including the latest from May 2025 which showed zero infested or eradicated units.

In 2020, there was a significant violation regarding building facade maintenance, with multiple cracks noted at the facade lintel between windows, though this issue appears to have been resolved with a penalty of $620. Earlier violations from 2018 concerned bulkhead door safety, including issues with self-closing mechanisms and illegal slide bolts. The building has shown consistent compliance with bedbug reporting requirements in recent years, with the most recent filings indicating proper reporting procedures have been followed.

The building's historical records show a pattern of addressing safety and maintenance issues once they are identified, with most violations being marked as "Close" after remediation. The property has maintained an active record of bedbug reporting compliance since annual reporting requirements were introduced, with no recorded infestations in the past four reporting periods. The latest bedbug report from May 2025 indicates proper reporting procedures have been followed, showing units have remained free of infestations since 2020. The building's permit records show at least one construction-related permit was issued in 2020, though specific details of the work are not provided in the available data.
