8644 24th Avenue, Brooklyn, NY 11214

8644 24th Avenue is a 2-story, 4-unit residential building constructed in 1930 and currently owned by Nick Giannopoulos. This Gravesend property has experienced several concerning issues over the past several years, with the most significant violations occurring between 2018-2020 when the cellar was found to be illegally converted into two Class A apartments, complete with bedrooms, living rooms, bathrooms, and kitchen facilities. These illegal units led to multiple Environmental Control Board violations in May 2019 related to occupancy contrary to building records, failure to maintain code compliance, and work performed without proper permits.

While these violations were marked as "resolved," they carried penalties totaling over $6,000. The building has also faced recurring issues with heat and hot water, most notably in late 2018 when HPD was unable to gain access to inspect the complaint. From 2021 to 2024, there have been four consecutive annual violations related to the failure to file required bedbug reports, which remain open as of April 2024.

Additional complaints to the Department of Buildings between 2018-2020 included concerns about illegal curb cuts, construction work, and certificate of occupancy issues, though most were closed without findings of violation. While there were multiple violations related to failure to certify corrections on immediately hazardous violations in 2019, these were ultimately dismissed. The building's record shows a pattern of maintenance and compliance challenges that have persisted over several years, with particular attention needed to the ongoing bedbug reporting violations and historical concerns about unauthorized cellar apartments.
