307 6th Avenue, Brooklyn, NY 11215
The 4-story, 8-unit tenement building at 307 6th Avenue in Park Slope, currently owned by Ellen Lee, has several significant issues as of July 2025. Most concerning is an ongoing Department of Health and Mental Hygiene investigation initiated in September 2024 regarding construction lead dust in common areas and apartments.
The building has also accumulated multiple active Department of Buildings violations related to the failure to file required external low-pressure inspections for the years 2019-2021, with these violations issued between April and June 2023. While the property has demonstrated effective bedbug management in recent years, with all units being listed as eradicated in the most recent 2024 filing, there have been recurring violations related to the annual bedbug reporting requirement under Housing Maintenance Code (HMC) § HMC, with notices of violation issued for several years between 2021 and 2024.
The building's bedbug reporting history shows no documented infestations in the past three reporting periods (2021-2024), and all units were listed as eradicated, indicating successful remediation efforts when infestations occurred. The property, built in 1920, is categorized as an Old Law Tenement, and while it has maintained compliance with bedbug eradication protocols in recent years, the current lead dust investigation and pending building safety violations are notable concerns for resident safety and building maintenance.
