493 Amsterdam Avenue, Manhattan, NY 10024

493 Amsterdam Avenue is a 5-story, 13-unit old law tenement building located in Manhattan's Upper West Side, built in 1891 and currently owned by Sophia Magnone. The building has experienced recurring utility issues in early 2025, with multiple complaints regarding heat/hot water and electrical outages, including emergency complaints filed between March and April 2025. Prior to these recent problems, the building had documented maintenance and safety concerns in 2021, including issues with heat, hot water, and various housing maintenance violations affecting Apartment 1A, such as inadequate heating, defective smoke/carbon monoxide detectors, and locked doors.

The building also had significant work completed in 2021, which generated multiple Environmental Control Board violations for unpermitted electrical work and excessive dust and debris throughout common areas, though these issues were subsequently resolved. The property has demonstrated compliance with bedbug reporting requirements since 2019, with no reported infestations, and achieved passing results in seven consecutive rodent inspections from 2017 to 2024, though a "Rat Activity" finding was noted in September 2020. Issues regarding illegal hotel rooms in the building were raised in 2024-2025, but inspectors were unable to gain access during their visits.

The building has maintained regular bedbug and rodent inspections, showing adherence to housing maintenance requirements, though access issues during inspections have been a recurring theme in both recent and past complaints. Three separate inspections conducted between 2018 and 2021 related to egress and fire escape concerns yielded no violations, and the building's annual bedbug reporting has consistently shown zero infested units. The most recent active complaint as of June 2025 is related to illegal hotel rooms, though inspection access has been unavailable for verification.
