Augrented Insights Report for 439 East 51st Street

The 36-unit, 9-story Beekman Mansion building at 439 East 51st Street in Midtown, constructed in 1925, has experienced several significant maintenance and compliance issues over the past five years. Most notably, there were multiple violations related to the building's exterior condition, including problems with facade maintenance and chimney support documented in 2021-2022, and failures to submit required Cycle 8C critical examination reports in 2022 and 2020, for which penalties were imposed ($3,125 each).

In 2019, the building had immediate emergency safety concerns regarding its sprinkler system, though no violations were issued following inspection. While the building has maintained consistent rodent inspection passes from 2010 through 2025, there have been periodic bedbug infestations, with the most recent report for 2023-2024 indicating no affected units. The property has shown some compliance issues with building codes, including a failure to file energy benchmarking reports in 2022, though this violation was dismissed.

Recent building inspections in 2023-2024 have not documented any serious violations, and the building received inspection results indicating no violations for ventilation/vent/exhaust complaints filed in 2023 and 2019. Multiple permits have been issued for various maintenance and repair work between 2019-2020, suggesting regular attention to building systems and infrastructure. The current ownership under Kimberly Mcdowelllois appears to be addressing maintenance issues more promptly, with recent years showing fewer serious violations and successful permit completions.
