947 Manhattan Avenue is a 4-story, 5-unit residential tenement building built in 1928 in Greenpoint, currently owned by Henry Kielmanowicz. The building has experienced recurring issues with heating and hot water, particularly evident in the pattern of complaints from 2019 through 2024, with multiple emergency complaints indicating either total loss or inadequate service affecting the entire building. Most recently, in January 2024, unit 4L was found to have multiple violations, including inadequate heating, mold presence in the bathroom, and a defective kitchen floor, though some violations were later closed. The building has undergone several inspections and received various citations for safety violations, including failure to maintain proper notices for smoke detectors and carbon monoxide detectors (closed in May 2024) and issues with tenant protection plan postings during construction. Recent complaints include a 2024 active complaint related to Local Law 188/17 compliance. The property has maintained a clean record regarding bedbugs, with no reported infestations in the past seven years, and passed a 2022 rodent inspection. There was a period of construction activity in 2019-2020 which generated multiple violations related to construction safety and tenant notification requirements, though these were resolved with penalties.
The building's service history shows a persistent pattern of heating system issues, with the most recent complaint in January 2024 being labeled as an emergency by HPD. Inspections have revealed various maintenance issues, particularly focusing on unit 4L, which has shown ongoing problems with mold and heating systems. The property has demonstrated compliance with safety regulations in recent years, with no new bedbug or rodent complaints since 2022, though a 2024 inspection noted various administrative violations that were subsequently corrected by May 2024. The building has undergone several permitted construction modifications, with records showing permits issued in 2019 and 2020 for various maintenance and improvement work.
