171 East 90th Street, Manhattan, NY 10128

171 East 90th Street is a 5-story, 16-unit residential building located in Manhattan's Upper East Side, constructed in 1940 and currently owned by Aimco 173 East 90th Street LLC. The property has experienced recurring heat and hot water issues, with building-wide outages reported in June and December 2018, and November 2021, though these were reportedly resolved promptly in each instance. In December 2018, the building received several violations related to emergency safety concerns, including obstructed fire escape access due to a metal shed and entangled wires, along with multiple signage and regulatory posting deficiencies - all of which were subsequently closed.

More recently, in mid-2023, there was a complaint regarding illegal hotel rooms in residential buildings, though this was determined to have no warranted violations upon inspection. The building has demonstrated consistent compliance with rodent control measures, passing multiple inspections between 2017 and 2025, most recently in May 2025. The property has maintained a clean record with zero reported bedbug infestations over the past five years, as evidenced by consecutive annual filings showing no affected units.

Between March and May 2025, there were multiple complaints regarding illegal conversions, with varying outcomes including "Oath Violation Served" and "Inspector Unable To Gain Access" for two of the complaints. The building's management has also maintained necessary permits, with a relevant electrical work permit issued in December 2018. The building's maintenance history suggests regular attention to health and safety requirements, with prompt responses to most service requests despite the recurring nature of heat and hot water issues.
