Augrented Insights Report for 350 East 91st Street

The 5-story, 20-unit tenement building at 350 East 91st Street, owned by Yine Acosta, has experienced significant maintenance and repair issues throughout 2024, particularly in the latter half of the year. Between September 2024 and May 2025, there were multiple complaints related to plumbing (including radiator and bathtub issues), flooring problems, and unsanitary conditions including mold across various units.

The building showed persistent rodent activity throughout 2024, with multiple baiting efforts and inspections indicating ongoing pest management challenges. Several violations were documented in October 2024, particularly affecting Apartment 8, including issues with plaster surfaces, floors, windows, and an alleged mouse infestation. The property faced structural stability concerns in late 2024, with multiple complaints regarding building shaking or vibration, though inspections generally found no violations warranting further action.

Environmental Control Board violations were issued in September 2024 related to water seepage and mold conditions in Apartments 8 and 12, along with an illegal duplex conversion complaint from October 2023 that was also marked as "Unable to Gain Access" during inspection. Despite these various issues, the building has maintained a clean bedbug record over the past several years, with no reported infestations since at least 2019. The most recent HPD inspection attempts in late 2024 were often hindered by access issues, leading to some complaints being closed without resolution.
