309 West 100th Street, Manhattan, NY 10025

The 5-story, 6-unit residential building at 309 West 100th Street, owned by Jose Cassorla, has experienced persistent rodent issues throughout 2023, with multiple complaints to the Department of Health and Mental Hygiene (DOHMH) indicating rat sightings and conditions attracting rodents. Six rat sightings were reported between January and April 2023, followed by two instances of conditions attracting rodents in June.

The building underwent several inspections during 2023, with significant findings including "Rat Activity" in multiple inspections, though it passed some compliance inspections. The most recent inspection in August 2024 showed a "Passed" result, suggesting recent improvements in pest control measures. The building's history also shows previous challenges with pest management, particularly with bedbugs, as indicated by Housing Maintenance Code violations in 2022 and 2023 related to the failure to file annual bedbug reports.

However, official bedbug reporting from 2020 through 2025 shows zero infested units, zero eradications, and zero re-infestations, suggesting successful management of this particular issue despite the earlier reporting violations. The property has experienced other rodent-related issues throughout 2023, with multiple instances requiring bait application in February and March 2023, though most recent inspections indicate improvements in overall pest management. Interestingly, while the building is classified as "HERETOFORE CONVERTED CLASS A," it has an unusual property classification history indicating it has been previously converted, though specific details of the conversion are not provided in the records.
