511 West 151st Street, Manhattan, NY 10031

The 31-unit, 5-story tenement building at 511 West 151st Street in Hamilton Heights, built in 1900 and currently owned by Guibor Rosenstock, has experienced recurring maintenance challenges throughout 2024-2025. The most pressing issues involve consistent heating system problems, with multiple reports of heat and hot water outages affecting the entire building, particularly during early 2025. Recent inspections have revealed ongoing concerns with building maintenance, including a June 2025 paint/plaster violation related to ceiling conditions, and several December 2024 violations in Apartment D1 involving water leaks, plaster repairs, and compromised ceiling surfaces.

Other notable violations detected in December 2024 include lead paint hazards in Apartment B3, pest infestation in Apartments B1 and E4, and issues with window guards and fire escape access in Apartment B3, all classified as Class C violations requiring prompt attention. The building has a documented history of maintenance issues requiring attention from the Department of Housing Preservation and Development (HPD), with multiple emergency and non-emergency complaints being filed and subsequently closed. Between 2023 and 2024, the property attracted attention for various violations related to unauthorized renovation work, leading to ECB violations with fines totaling $10,000 in 2020. The building's most recent inspections for rodent control have passed, though the property showed evidence of rat activity in mid-2022.

Notably, the building has maintained a consistent record of zero bedbug infestations reported between 2019 and 2024, and recent environmental control board violations regarding work without permits from 2018-2020 have been resolved, including one instance of unlawful work during a stop work order in 2018. The building's complaints filed with the Department of Buildings (DOB) show regular monitoring of structural stability concerns, though inspections in 2023-2024 found no violations. While some historical permit violations regarding work performed without proper authorization were identified and resolved, including electrical, plumbing, and construction work in 2020, the property has since demonstrated better regulatory compliance. The most recent building permits issued in 2018 (for plumbing and electrical work) were properly documented, suggesting improved adherence to proper permit procedures.
