817 Knickerbocker Avenue, Brooklyn, NY 11207

817 Knickerbocker Avenue is a 3-story, 6-unit New Law Tenement building constructed in 1912 in Bushwick, currently owned by Knickerbocker Apts Corp. The property has experienced recurring maintenance issues, with the most recent cluster of problems occurring in April 2024, when violations were issued for multiple emergency conditions including water leaks (heavy flow), mold, ceiling paint/plaster issues, and window frame problems. These violations were subsequently closed.

In 2024, significant violations were documented in Apartment 2R related to lead paint hazards, defective window guards, and door issues, all of which were closed following certification of repairs. The building's systems have experienced various problems over the years, including electrical issues, a power outage, safety concerns with the fire escape and window guards in 2020, and general maintenance problems with the intercom system. The property has faced regulatory scrutiny, including violations for failure to file annual inspections (in 2019 and 2023) related to boiler and low pressure systems, though these violations were ultimately dismissed.

Rodent activity has been documented in 2024, with a compliance inspection showing "Rat Activity," though a subsequent inspection in April 2025 resulted in a "Passed" rating. The building's bedbug reporting history from 2020 through 2025 shows no infestations or required eradications during the reporting periods, indicating effective pest management. While the building has demonstrated compliance with various health and safety regulations, the recurring nature of maintenance issues, particularly in recent years, suggests ongoing challenges with maintaining building systems and addressing resident concerns.
