711 Knickerbocker Avenue, Brooklyn, NY 11221

The 6-unit, 4-story NEW LAW TENEMENT building at 711 Knickerbocker Avenue in Bushwick, owned by Guy Altberg and constructed in 1910, has experienced significant maintenance challenges over the past two years. Recent inspections in 2024-2025 have revealed ongoing issues in Apartment 3R, including multiple open violations for water leaks, mold, and pest infestations (specifically roaches and mice), though some violations related to ceiling water leaks and bathroom conditions were closed after inspection.

The building has also faced recurring plumbing problems, with multiple complaints about water leaks and bathtub/shower issues, as well as appliance problems including a refrigerator complaint in May 2025. A concerning pattern of water-related issues is evident, with four separate water leak complaints (two classified as "heavy flow") recorded between 2023-2025. The property has had some serious habitability concerns, including an emergency heating/hot water complaint in January 2023 and multiple instances of emergency maintenance requests.

Additionally, there are currently active Department of Buildings violations related to the failure to file inspection reports, showing ongoing compliance issues. While the building has maintained a bedbug-free status based on annual reporting since 2022, rodent control has been a persistent challenge, with multiple baiting operations conducted in 2024 and several failed inspections indicating continued rat activity through April 2025. The building's maintenance history demonstrates a pattern of recurring issues that require attention, particularly regarding water infrastructure and pest control, though some recent violations have shown compliance efforts by the owner.
