5601 6th Avenue, Brooklyn

    A Sunset Park walk-up under new management that carries open housing violations and heavy curb friction.

    Sold in March 2023 for $2.96M to 606 56th St LLC after four decades of family-corp ownership under Serres Management. It's a 14-unit Sunset Park walk-up where maintenance items have lingered on the books. Three things to know:

    Eleven open violations remain on file, including three immediately hazardous items. The building carries 11 open housing violations, including three Class C immediately hazardous orders. These cover missing or defective self-closing doors in Apartment C4, locked access to the cellar boiler room, and heat supply issues. There are also open Class B citations for kitchen mold and plaster decay.

    Curb space and driveways within three blocks see heavy parking pressure. 260 illegal parking calls were filed within three blocks over the past year—mostly hydrants blocked by short-term parking rather than abandoned cars—alongside 80 blocked driveway calls. Street noise and double-parking friction are constant on this stretch.
