429 Wythe Avenue, Brooklyn, NY 11249
The 4-story, 3-unit OLD LAW TENEMENT at 429 Wythe Avenue in Williamsburg, owned by Aaron Aaronson, presents a concerning pattern of unresolved violations and safety concerns. The building, constructed in 1910, has been cited repeatedly from 2021 through 2024 for failing to file required annual bedbug reports, with the most recent violation noted in April 2024.
More critically, the property has faced serious occupancy issues, with multiple violations issued in 2023-2024 indicating illegal conversions and unauthorized additional dwelling units, particularly affecting the 3rd, 4th, and 5th floors. These violations resulted in significant penalties, including $125,000 in 2024 related to defacing an active vacate order, and $50,000 for maintaining unauthorized dwelling units.
The building has also experienced various maintenance and safety concerns, including inadequate lighting at the front entrance (2018), multiple violations regarding smoke detector requirements and housing information notices (2018), security issues with mailboxes, and electrical safety concerns in the public hall. Recent Department of Buildings inspections in 2025, while finding no immediate violations, occurred in the context of ongoing concerns about building maintenance and safety compliance. The property has a history of elevator issues (2022) and persistent housing maintenance code violations, suggesting ongoing challenges with building maintenance and regulatory compliance.
