621 Vanderbilt Avenue, Brooklyn, NY 11238

621 Vanderbilt Avenue is a 4-story, 4-unit residential building constructed in 1898, currently owned by Alon Ashourzadeh. The property has experienced recurring heat and hot water issues, with multiple complaints filed between 2020-2024, including three separate incidents in January 2024 alone, all resulting in violations. More recent concerns include lead paint hazards and security issues in apartment 4, documented in April 2024 violations, specifically regarding peeling paint, defective door hardware, and security features.

The building has also faced infrastructure challenges, including flooring problems (notably a floors issue reported in October 2023 and January 2024), and electrical concerns as evidenced by a November 2020 power outage complaint. The property has undergone several inspections and has been found to contain some maintenance and safety deficiencies requiring attention. In early 2024, multiple violations were issued regarding safety signage requirements (smoke detectors, carbon monoxide detectors, etc.) in common areas.

While rodent activity was noted in 2023 with bait applications implemented, recent inspections in 2024 and 2025 have shown improved results with "Passed" ratings. The building's bedbug report for the period of 2023-2024 indicates no infestations or re-infestations during the reporting period. Additionally, three complaints regarding work without permits were filed in 2024, though inspections did not warrant any violations. The building's management has generally responded to complaints, as evidenced by the closing of numerous HPD and Department of Buildings complaints, though access issues have occasionally prevented inspections from being completed.
