511 Williams Avenue, Brooklyn, NY 11207

511 Williams Avenue is a 2-story, 4-unit residential building constructed in 1930, currently owned by Kamalodeen Safi. The building has experienced recurring maintenance issues over recent years, with the most significant cluster of problems occurring in 2023, including pest infestations, water leaks, and door/window-related concerns. Between April and July 2023, multiple reports documented water leaks (including one describing damp spots), door and window problems, and unsanitary conditions such as mold.

More recently, in July 2023, the building received multiple violations related to safety and regulatory compliance, including failures to properly post carbon monoxide and smoke detector requirements, building registration information, and gas leak procedures. These violations were categorized as Class A and B, indicating varying levels of seriousness. The property's maintenance history also reveals some concerning patterns, including three separate water leak complaints between 2021-2023, and multiple door/window-related issues.

In 2019, there were serious concerns about illegal construction work in the cellar, including the erection of walls with doors and locks, for which penalties were imposed and resolved. However, as of May 2025, the building's most recent bedbug report shows no current infestations or eradication efforts needed. Historical records indicate the building had passed rodent inspections in 2011 and 2012, suggesting previous pest issues may have been addressed. While some past violations were corrected, as evidenced by their "Closed" status, the current open violations from July 2023 related to safety postings and building registration requirements indicate ongoing regulatory compliance challenges.
