3901 Nostrand Avenue, Brooklyn, NY 11235

3901 Nostrand Avenue, a 6-story, 243-unit residential building in Sheepshead Bay built in 1961, has experienced recurring heating system issues over the past two years, with multiple complaints about inadequate heat and hot water recorded between June 2024 and February 2025. The most recent heating-related complaints, filed in June 2025, resulted in violations being issued by the Department of Housing Preservation and Development (HPD), marking a pattern of unresolved heating system maintenance. The building has also faced significant safety concerns, particularly during 2024-2025, including multiple violations related to smoke and carbon monoxide detectors in Apartment 6J, with inspections revealing defective devices and inadequate hot water provision. An emergency complaint filed in February 2025 further highlights ongoing maintenance challenges.

The elevator system has been a recurring maintenance focus, with multiple Department of Buildings (DOB) complaints and violations between 2019 and 2023. Specific mechanical issues were documented in 2022, including problems with hoist ropes, brake pads, and safety features, leading to penalties that were subsequently resolved. The building has undergone several inspections regarding rodent presence, with the most recent bedbug report from December 2024 indicating no active infestation, though there were multiple reports between 2019 and 2023 showing varying unit infestation levels. Various violations have been issued over the years, including issues with self-closing doors in the laundry room and boiler room, and a history of work without proper permits that was documented between 2019-2021.

The property has maintained compliance with Local Law 188/17 inspections as of February 2024, though concerns about elevator safety and mechanical systems persist based on historical data. The building's maintenance history, while showing some responsive actions to violations and complaints, indicates ongoing challenges with fundamental systems such as heating and elevator functionality, as well as periodic safety equipment maintenance. Recent bedbug reports show improved conditions compared to earlier years, and rodent inspections from 2017-2016 passed. The current ownership under Jorge Chiriboga has dealt with numerous compliance issues requiring attention to building systems and safety equipment, particularly during the past three years.
