AI summary · updated June 2026

The 8-story, 40-unit residential building at 412 West End Avenue, owned by 412 West End Realty LLC, has experienced recurring heat and hot water issues throughout 2024-2025, with multiple emergency complaints recorded for both apartment-specific and building-wide outages. The property has also faced persistent rodent problems, with rat activity documented in inspections from 2022 through 2025, including recent compliance inspections showing rat activity in early 2025. Multiple housing maintenance code violations are currently affecting apartments 1S, 2G, and 7B, with issues including damaged plastered surfaces, previous fire damage, and safety concerns related to smoke and carbon monoxide detectors.

Recent inspections performed under the FISP (Facade Inspection and Safety Program) initiated in 2023 identified concerns with building walls, including spalled bricks and defective mortar joints on the east and south elevations. The building's elevator system has been a recurring focus of complaints, with multiple reports of defective service between 2021 and 2024, though inspections typically found no violations warranting action. While the building has maintained a record of zero bedbug infestations in recent years, there are documented issues with pest control, particularly mice in apartment 7B throughout 2023-2024. The property has experienced several plumbing and sanitary issues, including confirmed pest infestations and water supply problems, though inspections by HPD often resulted in either no violations or temporary conditions being addressed promptly.

The building's maintenance history shows a pattern of responding to emergency complaints, though some issues like heat and water service disruptions appear to be recurrent. Safety systems were notably impacted by violations in 2024, warranting attention to building safety equipment including fire escapes and detection systems. The sidewalk and scaffold conditions during construction and repair work have also generated multiple complaints regarding pedestrian safety and compliance with code specifications.

The property has maintained appropriate documentation showing no bedbug activity in the past several years, with regular filings indicating eradication efforts where necessary. While many violations have been resolved through inspection and correction processes, several remain active as of the current date. Recent permits issued for the building suggest ongoing maintenance and improvements are being undertaken, though supervision and inspection records indicate previous concerns have emerged periodically requiring attention.
