4103 7th Avenue, Brooklyn, NY 11232

The 20-unit, 4-story New Law tenement building at 4103 7th Avenue in Sunset Park, owned by Scott Castellano, has experienced ongoing heating system challenges in early 2025, with multiple complaints about building-wide heat and hot water issues between January and February 2025, though most were resolved relatively quickly. The building has several active Housing Maintenance Code violations from late 2024, primarily concentrated in apartment 1C, including safety concerns such as missing carbon monoxide detectors, required repairs to various surfaces, and issues with self-closing doors.

The Department of Buildings has documented serious concerns about building safety and maintenance, with two active Environmental Control Board violations from 2021 regarding failure to maintain code compliance related to fire escape pathways, resulting in significant penalties. Previous complaints from 2018-2022 suggest issues with building access, illegal conversions, and egress concerns, though these appear to have been resolved. The building has maintained a clean record regarding bedbug infestations, with zero reported cases in official filings since 2020.

Regular rodent inspections conducted in 2017, 2020, 2021, and 2022 have all passed, indicating effective pest management. A series of complaints and violations from 2024-2025 suggests ongoing maintenance challenges, particularly regarding the building's heating system and various apartment repairs, though some of these issues stem from difficulties in obtaining access for inspections. While the building has shown consistent compliance with bedbug and rodent control regulations, the recent heating system problems and multiple active violations related to safety and maintenance suggest areas requiring attention.
