1143 1st Avenue, Manhattan, NY 10065

1143 1st Avenue is a 17-unit, 5-story Old Law Tenement building constructed in 1910 in Manhattan's Upper East Side, currently owned by Flavia Verzirolli. The building has experienced persistent heating system issues, with multiple complaints about lack of heat or hot water affecting the entire building during 2023-2025, including closely clustered incidents in March 2025 and throughout 2024. Many of these complaints were not able to be verified due to access issues, though some were partially resolved.

The building's boiler system has been a notable area of concern, with multiple violations recorded in 2021 including issues with safety valve discharge, standing water, and combustible materials in the boiler room, resulting in a penalty of $312. A March 2023 inspection related to sidewalk safety found no violations. The property has maintained a generally clean record regarding pest control, with no bedbug infestations reported in the past five years (2019-2024), though there was a documented incident involving five units in 2018-2019.

Rodent inspections from 2010 to 2019 regularly showed passing results. Recent building maintenance issues have included unsanitary conditions in garbage/recycling storage documented in late 2023. The building's heating system appears to be an ongoing maintenance challenge, with multiple emergency complaints filed through 2025. While some health and safety concerns have been addressed over time, including previous boiler violations, the recurring nature of heating complaints suggests persistent infrastructure challenges.
