403 East 78th Street, Manhattan, NY 10075
403 East 78th Street is a 4-story, 7-unit old law tenement building located in Manhattan's Upper East Side, owned by Bono Occidental, LP and constructed in 1910. The building has faced recurring administrative challenges, particularly regarding bedbug reporting compliance, with violations recorded in 2021, 2022, and 2023 for failing to file annual reports as required by housing maintenance code. In 2018, the building underwent significant scrutiny for potential illegal hotel room conversions, with multiple complaints filed between September and November, including an investigation that resulted in an Oath violation being served.
During this period, an Environmental Control Board violation was issued for unauthorized work creating additional bedrooms on the fourth floor, resulting in a $1,600 penalty. The building has maintained good general maintenance practices, as evidenced by passing multiple rodent inspections from 2011 through 2019, with only one bait application noted in 2012. Recent records show improved compliance, with the most recent bedbug report for the period 2022-2023 showing no infested or re-infested units.
The building had two permits issued for electrical work in 2020 and 2022, both of which were properly filed and issued. A complaint about illegal after-hours work in October 2022 was investigated but resulted in no violations being warranted. While the building's history shows periods of compliance issues, particularly regarding bedbug reporting and unauthorized modifications in 2018, recent records indicate improved regulatory adherence and building maintenance practices.
