Augrented Insights Report for 99 Diamond Street

99 Diamond Street is a 3-story, 6-unit residential building in Greenpoint, Brooklyn, built in 1930 and currently owned by Malgorzata Wieckowska. The building has experienced several maintenance issues in recent years, with the most significant being a heat and hot water outage affecting the entire building in November 2024, though HPD was unable to access units for inspection.

Between March and April 2024, multiple violations were documented regarding self-closing doors throughout the building, including fire doors in the public hallways, with specific violations noted for apartment 3L. Additional violations in 2024 included a missing self-closing device at the building front entrance and an overdue bedbug report filing. The building's history shows recurring issues with door maintenance and compliance with safety requirements, particularly regarding self-closing doors which were found defective or missing in multiple locations as recently as 2024.

While there have been complaints about heat and hot water, these issues have often resulted in HPD being unable to gain access for inspection. Notably, the building has maintained a clean record regarding bedbugs, with no reported infestations in the past three years, and recent rodent inspections in 2024 and 2025 have shown passing results, indicating effective pest control measures. The property has had two building complaints investigated in recent years (2021-2024) regarding construction work and permits, but in both cases, no violations were warranted at the time of inspection.
