339 9th Street, Brooklyn, NY 11215

339 9th Street is a 4-story, 5-unit Old Law Tenement apartment building located in Park Slope and constructed in 1925, currently owned by 339 Ninth St, LLC. The building has experienced a cluster of health department-related issues in 2025, with eight separate Department of Health and Mental Hygiene (DOHMH) complaints primarily regarding food preparation locations and rodent/insect/garbage concerns between January and May 2025, with one additional complaint about food odors.

These complaints have all been closed, though they suggest persistent sanitation issues in food-related areas. The building also faced structural concerns in December 2021 when a vehicle reportedly impacted the structure, causing stucco damage and resulting in an active Building Department violation that remains unresolved as of October 2023. The property has shown recent compliance with bedbug reporting requirements, with no documented infestations, eradications, or re-infestations reported in the last four annual filings between 2022 and 2025.

Prior to the recent DOHMH complaints, the building had established a record of passing rodent inspections, with the last documented inspection in November 2019 showing compliance. A sidewalk shed complaint was investigated in January 2025 but determined to warrant no violations. While the building has maintained bedbug-free status according to official reports, the pattern of recent health department complaints in 2025 indicates potential ongoing maintenance or sanitation challenges, particularly related to food preparation areas.
