21 Union Square, Manhattan, NY 10003
21 Union Square, a 12-story Class A residential building constructed in 1986 and currently owned by Linda Chiarelli, has experienced recurring heating issues in early 2025, with two separate complaints in January and February reporting problems with heat and hot water, though both were resolved promptly according to HPD records. The building faced multiple concerns with standing water in late 2023, with three complaints logged in October 2023 that remained unresolved as of the last inspection, and there were instances of food poisoning reported in late 2023 requiring investigation. Earlier maintenance history shows a pattern of heating system problems in 2022, with complaints filed regarding both apartment-specific and building-wide heat/hot water issues, along with a mold complaint that could not be inspected.
The building's bedbug reports indicate minimal infestation issues, with only one reported case in 2022 that was reportedly eradicated. The property has undergone various inspections and received multiple violations related to building maintenance, including concerning exterior conditions. Most notably, in 2018-2020, there were violations regarding spalling concrete and exposed rebar on balconies that required attention, with penalties imposed and subsequently resolved.
The building's parking structure has also been cited for maintenance issues, with violations recorded in 2024 regarding concrete conditions. Recent bedbug reports (2023-2025) show no current infestations, and rodent inspections conducted annually from 2010 to 2014 consistently passed, indicating generally effective pest management practices. While the building has experienced various maintenance issues over the past few years, recent bedbug inspections have shown no current infestations, and rodent control appears to have been maintained successfully.
