Augrented Insights Report for 4701 15th Avenue

The 6-story, 65-unit tenement building at 4701 15th Avenue in Borough Park, owned by David Nierenberg, has experienced various maintenance and safety issues since October 2020. Most notably, there have been recurring complaints and violations related to heating systems, with multiple heat and hot water complaints received in late 2022, and several pest control issues, including two separate unsanitary condition complaints regarding pests in 2022 and 2023. More recent concerns include a partial stop work order in March 2025 regarding suspended scaffolds and an open violation from September 2024 regarding a failure to file the 2023 external low-pressure inspection.

The building's fire safety systems have also received attention, with an environmental control board violation in 2023 citing disrepair of a fire escape ladder and multiple violations related to self-closing doors in public areas. The property has undergone several inspections and received multiple citations for various safety and maintenance issues. In 2023 alone, there were multiple violations related to door maintenance, including defective self-closing doors at the compactor closet on different floors, as well as violations for construction encumbrances in public areas.

The building has consistently passed rodent inspections in recent years and has reported zero bedbug infestations in its annual filings since 2021. Inspection history shows some concerning patterns, such as repeated heating system issues, though many complaints were resolved with no violations issued upon inspection. The building's owner has faced penalties for various violations over the years, including a $625 fine in 2019 for failure to maintain fire stopping in the cellar level gas/electrical meter room and a $1250 penalty for obstructed exit passageways. While many violations have been resolved, several active violations related to low-pressure inspection filings from 2021-2023 remain on record.
