20 Arden Street, Manhattan, NY 10040

20 Arden Street is a 5-story, 25-unit residential building located in Inwood, built in 1915 and currently owned by Ivan Kaczor. The building's maintenance history reveals recurring issues with water systems and heating, particularly during the 2018-2022 period, with multiple complaints regarding lack of heat and hot water affecting both individual apartments and the entire building. Water-related problems have been persistent, including a significant water leak with heavy flow reported in October 2018, and more recent plumbing issues in July 2022.

The building has undergone regular rodent inspections between 2018 and 2025, with all but one passing (an August 2024 inspection noted rat activity). Notably, a recent mold emergency was reported and closed in June 2025, and there is currently an open non-emergency door/window issue as of March 2025. The building's bedbug reporting history shows relatively few incidents, with only two reported cases (in 2018-2019 and 2019-2020) among seven consecutive annual filings between 2019-2025 showing zero infestations.

The property has maintained compliance with Housing Maintenance Code requirements, though there were two Class C violations in October 2018 related to inadequate hot and cold water supply in Apartment 2A that were certified corrected. An inspection by the Department of Buildings in September 2023 found no violations warranting further action. While the building has experienced recurring maintenance issues, particularly with heating and water systems, recent inspection results show improved rodent control, and the lack of bedbug infestations in recent years suggests effective pest management practices.
