501 Lefferts Avenue is a 6-story, 60-unit residential building constructed in 1926, currently owned by Victor Ibanez. The building has experienced recurring issues with heat and hot water systems throughout 2025, with multiple emergency complaints filed in June 2025, most recently in June 2025, though HPD inspections often found service restored prior to inspection. The building has also faced concerns regarding water supply issues, safety violations related to fire escapes, and unsanitary conditions in garbage storage areas, though many of these complaints were closed without finding violations. Notably, there are serious ongoing issues with building safety and code compliance, including active Department of Buildings (DOB) violations from 2022-2025 regarding failure to maintain proper permit postings, excessive construction dust in common areas, and issues with fire safety systems. ECB violations from late 2024 indicate problems with construction work and permit posting procedures, while recent rodent inspections show alternating results between "Passed" and "Rat Activity" between 2021 and 2025. The building has maintained relatively low bedbug activity, with only two reported cases since 2020, both showing prompt eradication. An active complaint regarding elevator service was filed in June 2025, though the building has generally maintained its elevator system through recent inspections. The property has numerous historical violations primarily related to immediately hazardous conditions that have been resolved or dismissed, though some remain active as of 2025.
