3901 7th Avenue, Brooklyn, NY 11232

The three-story, four-unit tenement building at 3901 7th Avenue in Sunset Park, owned by Wai Sum Yu and constructed in 1935, has experienced several notable incidents and violations in recent years. Most significantly, there were two heat and hot water emergencies in December 2018 affecting the entire building, though these issues appeared to be resolved relatively quickly.

The building has also been subject to recurring violations regarding high-pressure inspection documentation, with multiple active violations as of June 2023 for failing to file internal and external high-pressure inspection reports between 2018 and 2022. While the building has maintained an active Bedbug Reporting compliance record with no reported infestations in the last three filing periods (2022-2024), there was an initial rat activity detection in October 2018, though subsequent inspections in December 2018 and March 2017 passed without issue.

The property has consistently filed Bedbug Reports showing no infestations between 2020 and 2024, suggesting effective pest management practices. The building's maintenance history shows some attention to compliance requirements, as evidenced by the regular filing of Bedbug Reports and Rodent Inspections, though the significant number of active high-pressure inspection violations as of mid-2023 indicates a concerning pattern of non-compliance with safety system maintenance requirements. The property has maintained a relatively stable unit count and structure since its construction, typical of historic tenement buildings in the area.
