4808 4th Avenue, Brooklyn, NY 11220
The 9-unit, 3-story building at 4808 4th Avenue in Sunset Park, owned by Mario Valdes and constructed in 1931, has experienced several recurring issues in recent years, particularly concerning heating systems and boiler functionality. Between late 2024 and mid-2025, there were multiple complaints about heat and hot water outages affecting the entire building, with three emergency complaints filed in October-November 2024 and June 2025.
The building's boiler system has been subject to scrutiny, with a Department of Buildings inspection in June 2025 resulting in an oath violation, and previous concerns about electrical wiring noted in July 2021 when an inspector was unable to gain access. Several safety-related violations have been documented, including multiple notices regarding defective self-closing doors at building entrances and fire doors in late 2024, which were classified as Class C violations requiring prompt attention.
The building has maintained good pest control practices, with bedbug reports filed annually since 2019 showing zero infested units or re-infestations. Recent health-related incidents include two food-related complaints in 2024-2025, one involving spoiled food in a food establishment and another concerning food poisoning, though these appear to be linked to local businesses rather than the building itself. The property has also experienced some regulatory challenges, including two active ECB violations from 2021 regarding unpermitted work related to a conveyor installation, with one imposing a $2,500 penalty.
