21 East 21st Street, Manhattan, NY 10010

21 East 21st Street is a 6-story, 26-unit residential building located in Manhattan's Flatiron District, owned by Doron Markowitz and built in 1878. The property has experienced several significant maintenance issues over recent years, most notably recurring violations related to bedbug report non-compliance, with open violations recorded in 2022, 2023, and 2024.

A concerning heat and hot water outage affected the entire building in December 2022, though this was reportedly resolved when HPD responded to the complaint. The building's safety systems have also been a persistent concern, with active Environmental Control Board violations as of 2019 regarding a lack of required sprinkler systems and additional issues related to fire extinguisher maintenance. The property has faced challenges with timely reporting and compliance, including an ECB violation from 2018 for failure to submit a required Cycle 8B report of critical examination for the exterior walls, though this was later resolved with a penalty.

Multiple inspections between 2010-2016 showed consistent passing results for rodent inspections, but recent years have seen increased regulatory scrutiny. The building has had complaints about illegal after-hours work in late 2022 and issues related to COVID-19 safety measures in 2020, though these complaints were investigated without violation findings. While some violations from previous years have been resolved or dismissed, the property continues to have open violations requiring attention, particularly regarding bedbug reporting compliance.
