403 East 70th Street, Manhattan, NY 10021

403 East 70th Street is a 5-story, 17-unit New Law Tenement building located in Manhattan's Upper East Side neighborhood, constructed in 1910 and currently owned by Sheldon Knecht. The building has recently faced several significant maintenance issues, particularly with pest infestations, including three separate complaints in 2024 alone (September and October) affecting apartment 8, which was cited for both mice and door integrity violations.

Prior to this, there were multiple pest-related complaints in 2023 and 2024, and the building underwent rodent inspections between 2010-2020, achieving generally passing results. The property has a concerning history of heat and hot water issues, with complaints filed in December 2019 and January 2020 showing temperatures exceeding 130 degrees in apartment 5,though more recent bedbug reports from 2022-2025 indicate no infestations.

The building has experienced several regulatory scrutiny events, including multiple complaints about unauthorized work (2022) and two recent complaints about illegal signage (2024), though most of these investigations resulted in no violations being found. While the building has some persistent maintenance issues, particularly regarding pests and heating systems, it's worth noting that most recent inspections have shown improvements in certain areas, including passing rodent inspections in multiple years and consistent reporting of zero bedbug incidents since 2018.
