423 East 90th Street, Manhattan, NY 10128

The 8-story residential building at 423 East 90th Street, owned by Rose Caiola, has faced recurring pest-related issues over the past few years, with the most recent complaints about unsanitary conditions involving pests submitted in May and June 2025. These complaints prompted attempted inspections by the Department of Housing Preservation and Development (HPD), but the inspectors were unable to gain access to the units. The building has a documented history of rodent management, with regular inspections showing a mix of "Passed" results and bait applications between 2021 and 2024, indicating an ongoing monitoring and pest control program.

While there was one rat sighting in 2021 that resulted in a Department of Health and Mental Hygiene inspection with no violations found, the building's most significant current concerns appear to be the unresolved pest complaints from 2025. The property has two active violations as of 2023 related to inspection filings: one for failure to file the 2020 External Low Pressure Inspection and another for not submitting the FISP Cycle 9B Technical Report by the required deadline. These violations, though administrative in nature, represent potential maintenance oversight.

The building's bedbug reporting history shows minimal infestation issues, with only one reported case in 2022 and none in subsequent years, suggesting effective management of this particular pest concern. Previous Department of Buildings complaints regarding site conditions from 2018 were investigated but found no violations at the time of inspection. The building's construction date is 1987, and it contains 49 residential units, with the current pest-related issues being the most pressing concern based on available data.
