517 Graham Avenue, Brooklyn, NY 11222
The three-story, six-unit tenement building at 517 Graham Avenue in Greenpoint, constructed in 1920 and currently owned by John Imperatore, has experienced several notable maintenance issues and violations in recent years, particularly during late 2023 and 2024. Most concerning was an emergency heat and hot water complaint in November 2023 that HPD could not verify due to lack of access, followed by a plumbing emergency in July 2024.
The building currently has multiple open violations from a November 2023 inspection, including safety issues related to smoke and carbon monoxide detector requirements, gas leak procedures, and alarm system functionality, as well as three specific violations in apartment 3R regarding various safety systems. Additional open violations involve missing or improper posting of important safety notices in the first-floor public hall. Recent inspections and service requests show ongoing maintenance needs, though the building has consistently filed bedbug reports showing no infestations or required eradication between 2020 and 2024, and passed a rodent inspection in 2014.
Two significant service requests regarding unsanitary conditions in garbage and recycling storage were made in 2024, though neither resulted in violations. While many of the building's recent complaints have been closed without violations, the pattern of maintenance issues, particularly regarding safety systems and building infrastructure, suggests ongoing challenges with building upkeep. The most pressing current concerns appear to be related to the building's safety system compliance and functionality, particularly affecting unit 3R and the first-floor common areas.
