51 East 78th Street, Manhattan, NY 10075

51 East 78th Street is a 5-story, 21-unit Old Law tenement building located in Manhattan's Upper East Side and owned by Mark Hoffman. Built in 1894, this property has experienced several notable incidents and maintenance issues over its history.

Most recently, in November 2022, there was an emergency heat and hot water complaint affecting the entire building, though this issue was subsequently resolved within a day. The building has maintained relatively good pest control records, with no recorded bedbug infestations in the past four reporting periods from 2020 to 2024, and consistent passing rodent inspections between 2010 and 2019. The property has several open violations that merit attention, including an active Department of Buildings violation from 2019 for failure to file the 2017 boiler inspection report, and historical issues with fire escape maintenance and carbon monoxide detector compliance.

A notable cluster of violations from 2004-2005 included issues with the fire escape security, boiler room access notice, and carbon monoxide detector installation in apartment 4A. Earlier violations from 1997 pertaining to the refuse chute warning sign and repairs to the boiler room wall and paving were all eventually certified as corrected by June 2022. The building has had multiple emergency work permits issued between 2018 and 2022, suggesting ongoing maintenance activity, though the nature of this work is not specified in the permit records.
