287 Onderdonk Avenue is a two-story, four-unit residential building constructed in 1930 and currently owned by John Imperatore. The building has experienced several recurring maintenance issues over recent years, with the most recent concerns centered around pest control and waste management. In April 2024, the Department of Health and Mental Hygiene documented rodent-related violations, which followed an earlier inspection in June 2024 where the building passed the compliance check, though an initial inspection in April 2024 noted rat activity. The property has a notable history of water-related problems, including multiple reports of slow leaks in 2019, which resulted in issued violations, as well as previous heat and hot water complaints that affected the entire building during the same period. There have been recurring issues with garbage and recycling storage, with violations noted in both 2021 and 2024.
