333 West End Avenue, Manhattan, NY 10023
333 West End Avenue is a 16-story, 50-unit residential building located in the Upper West Side, constructed in 1925 and currently owned by Louis Wolfowitz. The building has experienced several significant maintenance and safety events over the past five years.
In 2019, there was a heat/hot water issue reported through 311 that could not be verified by HPD inspectors. The building underwent various construction activities in 2021-2022, which resulted in multiple violations related to construction safety compliance, including issues with suspended scaffolds, lifelines, and failure to meet manufacturer's specifications. These construction-related violations typically received penalties between $625 and $2,500, though many were subsequently resolved.
More recent concerns include a November 2023 violation for failure to file the 2018 external low-pressure inspection, which remains active as of June 2025. The building's elevator system has required attention, with violations noted in 2021-2022, though these were ultimately resolved or dismissed. The property has maintained a relatively good record regarding pest control, with no reported bedbug infestations in the past three years (2021-2024), and recent rodent inspections in 2022-2024 generally passed, except for a failed inspection in 2022 for "Other Reasons." While there were reported instances of illegal activity and building vibrations in 2019, inspections did not warrant any violations, and the building has maintained regular permit filings for required maintenance and inspections through 2021-2022.
