Augrented Insights Report for 420 East 80th Street

420 East 80th Street is a 12-story, 156-unit residential building located in Manhattan's Upper East Side, constructed in 1961 and currently owned by Tomas Rosenthal. The building has experienced persistent pest control challenges in recent months, with multiple rodent sightings reported between April and May 2025, resulting in failed compliance inspections. The Department of Health and Mental Hygiene has documented violations requiring follow-up inspections.

Additionally, there have been two recorded bedbug infestation periods (2023-2024 and 2022-2023) with the most recent report showing 2 infested units as of December 2024. The building has a history of maintenance issues affecting resident comfort and safety, including multiple heat and hot water complaints. In 2025 alone, there were complaints about unsanitary conditions and pest problems, while 2023 and 2024 saw recurring heat-related issues.

The elevator system has been a recurring concern, with multiple inspection complaints between 2021 and 2023, though most inspections found no violations at the time. The building has also faced regulatory scrutiny, including violations for failing to submit required reports and for unauthorized construction work in 2022. More recently, in 2024, there was an Environmental Control Board violation regarding the parking structure inspection report, resulting in a $2,500 penalty. The property has maintained its Class A building status and continues operating under its original occupancy classification.
