320 East 90th Street, Manhattan, NY 10128

320 East 90th Street is a 5-story, 20-unit Old Law Tenement building constructed in 1940, currently owned by Frank Deguzman. The property has experienced recurring rat activity, with the most recent inspections in 2025 consistently showing evidence of infestation, including closed complaints from May 2025 and ongoing violations.

The building has also faced significant heating issues, as demonstrated by multiple emergency complaints in February 2024 regarding lack of heat and hot water, though some reports indicated restoration of service. Two fire safety violations were identified during a February 2024 inspection, including an obstructed fire escape and a non-self-closing door in the vestibule area. The building has a concerning history of access issues for inspections, including complaints about work without a permit in December 2024 and egress concerns in August 2020, both cases showing inspector inability to gain access on final attempts.

An active violation from June 2023 indicates a failure to file required low-pressure inspection documentation from 2019. In contrast, the bedbug reporting history from 2019 through 2024 shows no recorded infestations, with all reporting periods indicating zero infested or eradicated units. The building's maintenance history illustrates ongoing pest control challenges, particularly with rodent activity, despite regular baiting efforts and inspections, with the most recent rat sightings reported in January and May 2025.
