434 East 89th Street, Manhattan, NY 10128

434 East 89th Street is a 5-story, 20-unit residential building constructed in 1930 in New York's Upper East Side neighborhood. Owned by Ahron Freidus, this Old Law Tenement has experienced several notable issues over the past few years.

Most recently, in October 2023, the building received a Department of Health and Mental Hygiene (DOHMH) complaint regarding indoor air quality and chemical vapors, which resulted in an advisory being sent to the property management. The building's rodent situation has shown patterns of concern; while recent inspections in 2024 and 2023 passed, between 2021 and 2022 there was notably consistent documentation of rat activity with multiple compliance inspections showing violations, though more recent inspections have not returned to this problematic pattern. The building has had some significant maintenance issues documented, including a 2019 violation regarding emergency door conditions with excessive cracks and spalling paint.

This violation, which was resolved with no penalty imposed, demonstrates some of the building's structural maintenance challenges. On a more positive note, the building has maintained a consistent record of bedbug-free status since 2018, with no reported infestations or related remediation activities in any of the annual reports. The property management appears to have addressed most concerns as they arise, as evidenced by the relatively prompt closure of complaints, though the air quality issue from October 2023 indicates some ongoing monitoring may be necessary.
