Augrented Insights Report for 5820 21st Avenue

The two-story, one-unit building at 5820 21st Avenue in Borough Park, owned by Isac Goldberger, has a significant pattern of housing maintenance code violations over recent years. Most notably, there are recurring open violations from 2021 through 2024 regarding the failure to file annual bedbug reports in accordance with HPD requirements.

The building, constructed in 1931, previously experienced a cluster of violations in September 2019, all of which have since been closed (as of December 2019). These violations involved various safety and regulatory requirements, including the need to post proper notices regarding smoke detector requirements, carbon monoxide detecting device requirements, gas leak procedures, and the availability of the agency's housing information guide.

There was also a violation concerning the proper display of the building's registration number. While the 2019 violations were promptly certified as corrected within a few months, the more recent bedbug report violations continue to remain unresolved as of October 2023.
