320 West End Avenue, Manhattan, NY 10023
320 West End Avenue is a 14-story, 33-unit residential building constructed in 1924 in New York City's Upper West Side neighborhood, currently owned by Charles Lowery. The building has faced several maintenance and safety issues over recent years, with the most pressing concerns emerging in 2023. Notable violations include two separate instances of debris posing potential falling hazards in April 2023, leading to Oath Violations, and problems related to window-mounted AC units that year, resulting in an Environmental Control Board violation for improper installation without exterior brackets.
The building also failed to file its FISP Cycle 9B technical report by the February 2023 deadline, which remains an active violation as of July 2025. The property has experienced multiple compliance issues over the years, particularly concerning tenant safety protocols in 2021, when violations were issued for failure to post and distribute required notices. While there have been complaints about rodent sightings in 2022, inspections conducted in 2022, 2023, and the most recent in August 2024 all passed without violations.
The building's maintenance history shows regular inspections, with no recorded bedbug infestations reported across multiple annual filings from 2019 to 2024, indicating effective pest management. Previous violations in 2021 also included an Oath Violation for illegal after-hours work, though this was dismissed upon inspection. The building has obtained several permits for maintenance work, with the latest permits issued in 2021 for exterior work, and earlier permits related to plumbing work in 2018.
