1501 1st Avenue, Manhattan, NY 10075

1501 First Avenue is a 6-unit, 4-story Old Law tenement building located in Manhattan's Upper East Side, built in 1910 and currently owned by Aileen Mcnally. The building has experienced several significant maintenance issues over the past decade, most notably in 2018 when Apartment 2N was found to have multiple structural problems, including sloping floors in various rooms and bathrooms, along with safety concerns such as missing smoke and carbon monoxide detectors. These violations, classified as Class B and C, were issued following inspections in September 2018.

More recently, in October 2021, there was a building-wide heat and hot water outage that was resolved the following day. The building's management has faced additional scrutiny, with an active ECB violation as of May 2023 regarding an unauthorized business sign installation, and a secondary violation from September 2018 concerning excessive floor settlement in Apartment 2N that created safety concerns, though this was resolved. The maintenance and pest control history of the building shows some positive indicators, with no bedbug infestations reported in the past seven years (2019-2025), and the most recent rodent inspection in January 2023 resulted in a passing grade.

The building has undergone regular pest control measures, particularly in 2021-2022, with multiple bait applications recorded. While the building has demonstrated compliance with bedbug reporting requirements and maintains regular rodent inspections, the history of structural issues in Apartment 2N and past heating system problems suggest ongoing maintenance challenges. The property's violation history, while somewhat dated, indicates periods of significant maintenance concerns that have required intervention from city agencies.
