617 West End Avenue, Manhattan, NY 10024

617 West End Avenue is a 15-story, 33-unit residential building located in Manhattan's Upper West Side, constructed in 1925 and currently owned by Katherine Kline. The building has undergone several significant maintenance and construction activities over the past several years, with the most pressing recent issues relating to construction safety and façade work. In 2023, there was an active façade safety concern (LL11/98 Unsafe Notification) and a construction safety compliance action, though a stop work order was subsequently fully rescinded.

Earlier, in 2020, there were multiple safety violations related to construction activity, including an incident involving a pedestrian injury, which resulted in substantial fines totaling $7,500. The building has maintained good compliance with rodent inspections, passing all eight inspections conducted between 2018 and 2025. The property has experienced occasional maintenance issues affecting resident comfort, notably a heat/hot water complaint in late 2020 that was resolved within a week.

There was one significant violation regarding bedbug reporting requirements in 2021, though subsequent annual filings from 2019 through 2024 indicate zero infested units. The building has faced several administrative violations over the years, including failures to file various reports (FISP technical reports, energy efficiency reports), though most of these have been dismissed or resolved. The Department of Buildings records show consistent permit activity, with multiple work permits issued between 2019 and 2023 for various maintenance and repair work, suggesting regular upkeep of the building's infrastructure.
