523 East 84th Street, Manhattan, NY 10028

523 East 84th Street is a 4-story, 53-unit Old Law Tenement building located in Manhattan's Upper East Side, owned by Vincent Roos and constructed in 1910. The building's recent history shows a consistent pattern of rodent-related issues, with the most recent complaint filed in September 2023 noting a rat sighting, though the Health Department inspection found no violations.

The building experienced a lapse in energy benchmarking reporting in 2021, for which a violation was filed but later dismissed after an approved challenge. While the property has shown multiple instances of rodent activity, particularly notable in 2017 with three separate inspections indicating rat activity, most recent inspections have passed, including the latest rodent inspection in October 2023.

The building's bedbug reporting records for the past three years (2022-2025) reveal no confirmed infestations or eradications, showing a consistent pattern of zero infested or re-infested units across multiple reporting periods. The property's rodent management has included several inspections and bait applications, with varied results between 2017 and 2018, though more recent inspections from 2019 onward have consistently passed, suggesting improved pest management practices. The building's overall compliance record shows periodic violations, though many have been resolved or dismissed through proper channels, and recent inspections indicate active management of both rodent and pest control measures.
