321 9th Street, Brooklyn, NY 11215
The three-story, four-unit tenement building at 321 9th Street in Park Slope, owned by Lisa Aliberti, has been facing ongoing rodent control challenges in recent years. As of mid-2025, there is active rat activity on record, with the most recent bait application occurring in June 2025, following reports of rat activity in March and February 2025.
The building has passed some health inspections, including a November 2022 rodent inspection, but recent inspections have consistently shown the need for ongoing management of rodent issues. The property's sustainability reports indicate no bedbug infestations from 2021 to 2024, though there were two Housing Maintenance Code violations recorded in 2021 and 2022 regarding the failure to file annual bedbug reports, which have since been resolved.
The Department of Health and Mental Hygiene has conducted inspections in response to various complaints, including a food establishment grading issue in 2023 and a rat sighting complaint in 2022, both of which were resolved without violations being found. Additionally, there was a plumbing-related complaint in October 2021 that was investigated but found to warrant no violations.
