21 St Marks Avenue, Brooklyn, NY 11217

The three-story, three-unit, 1899 Old Law Tenement building at 21 St Marks Avenue in Park Slope, currently owned by Karen Brudney, has a notable history of housing maintenance and safety concerns over recent years. Most concerning are the recurring open violations, with the building having failed to file mandatory annual bedbug reports under Housing Maintenance Code requirements in 2021, 2022, 2023, and most recently in 2024.

These unaddressed violations indicate ongoing non-compliance with basic health and safety regulations. The building faced significant issues in late 2018 related to safety and occupancy matters, including violations regarding illegally installed steel bars on second-floor kitchen windows that obstructed fire escape passageways, and a problematic conversion that suggested the dwelling maintained three or more unauthorized units beyond its legal designation.

While these specific violations were ultimately resolved by early 2019, they reflect a period of serious safety concerns. The property has experienced persistent rodent issues, particularly notable between late 2014 and 2018, with multiple bait applications and inspections showing rodent activity, though a February 2018 inspection reported compliance. While there are no current open violations related to rodents or building safety, the repeated nature of the bedbug report violations over multiple years suggests ongoing management oversight.
