303 East 90th Street, Manhattan, NY 10128
303 East 90th Street is a 5-story, 40-unit Old Law Tenement building built in 1930 in the Upper East Side, currently owned by Ahron Freidus. The property has been experiencing persistent rodent infestation issues throughout 2025, with multiple reports of rat sightings and conditions attracting rodents between March and June 2025, including three inspections resulting in documented rat activity.
Additionally, the building has faced several maintenance challenges requiring attention to basic infrastructure, including multiple heat and hot water emergencies throughout 2024-2025, plumbing issues, dampness concerns, and problems with paint/plaster in various units. The building has a history of important safety violations that were addressed, including several Housing Maintenance Code violations in late 2024 involving life safety systems. These included defective carbon monoxide detectors, smoke detectors, and issues with self-closing doors in Apartment 2F, as well as a broken window counterbalance in Apartment 2D.
There were also concerns about hot water exceeding 130 degrees in Apartment 2H. Of note is the period from 2018-2019 when illegal transient occupancy issues were documented regarding Apartment 4G, resulting in four Environmental Control Board violations related to building safety systems and egress requirements, though these were resolved with penalties totaling $7,500. However, recent inspections indicate ongoing pest control challenges, as evidenced by repeated rodent activity findings in inspections throughout 2024-2025.
