874 Longwood Avenue is a 5-story New Law Tenement building constructed in 1904, currently owned by Keyoumars Keypour and containing 10 residential units. The building has experienced recurring maintenance and safety issues over the past three years, with particularly concerning patterns emerging in 2024-2025 including multiple unsanitary conditions, plumbing problems, and heating/hot water issues. Most recently in May 2025, the building had multiple simultaneous complaints regarding pests, heavy water flow, plumbing issues, mold, heating problems, and flooring concerns, though HPD was unable to complete inspections for most of these complaints. The building's maintenance history shows persistent challenges with rodent control, as evidenced by multiple bait applications throughout 2023-2025, and structural concerns with an active violation related to decorative stone above a window on the 5th floor issued in May 2024.
The apartment has undergone several inspections revealing various violations that have since been closed, including issues with door/window maintenance, flooring, and heating systems. Notable past violations include a 2022 infestation of mice and roaches in Apartment 4, and various plumbing and security issues affecting building access. The building has maintained a consistent pattern of reporting zero instances of bedbug infestations in recent years, with all previous reports showing eradication. Recent rodent inspection results show both rat activity and successful bait application, indicating ongoing pest control efforts. The building's age and history suggest regular maintenance challenges typical of older NYC tenements, though the frequency and nature of recent complaints indicate potential ongoing maintenance difficulties.
