159 Nassau Avenue, Brooklyn, NY 11222

The 4-story, 6-unit building at 159 Nassau Avenue in Greenpoint, owned by the Estate of Jan Bielen, has a mixed record of maintenance and compliance since its construction in 1930. The most significant recent issues occurred in early 2022, when multiple violations were documented in apartment 4L, including the presence of lead paint hazards, unsanitary conditions (mold and pests), and problematic walls requiring attention, along with a window guard violation that remains open as of the latest information.

These followed earlier complaints from 2021 regarding garbage/recycling storage. The building experienced a heat and hot water emergency issue in January 2021 that was promptly addressed, and several 311 service requests in 2022 regarding doors/windows, ventilation systems, and wall conditions resulted in some violations being issued. On a more positive note, the building's recent records from early 2025 show successful rodent inspections in both January 2025 and February 2024, indicating no pest control issues.

Additionally, the building has maintained a clean bedbug record for the last three reporting periods (2022-2025), with no reported infestations or eradications. While the building has faced various maintenance challenges, particularly between 2021-2022, the absence of recent bedbug reports and successful rodent inspections suggest improved conditions in recent years. However, it's notable that some violations related to lead paint hazards and window guards in apartment 4L remain open, and past issues with unsanitary conditions (both mold and pests) were documented.
