304 East 91st Street, Manhattan, NY 10128

304 East 91st Street is a 6-story, 12-unit New Law Tenement built in 1920, currently owned by Chris Paravalos and located in the Upper East Side. The building has experienced several significant incidents over the past few years, with the most recent being a mosquito infestation reported in April 2025.

In late 2021, the building had multiple maintenance issues requiring inspection by the Department of Housing Preservation and Development (HPD), including problems with a radiator, door, electrical outlet, and bathtub/shower, though no violations were ultimately issued for these complaints. The property has faced some concerning structural and occupancy issues, particularly regarding illegal conversions. In 2022-2023, there were two separate complaints about illegal conversions, one resulting in a $1,250 violation related to unauthorized occupancy changes.

Environmental Control Board violations were issued in November 2022 regarding unauthorized occupancy and work without proper permits, specifically concerning modifications made to Apartment 1B. The building's pest control history is generally positive, with regular rodent inspections showing compliance, though there were some initial rat activity concerns in 2016. Importantly, the building has maintained a consistent record of being bedbug-free since at least 2018, with no reported infestations in the past seven years.
