Yes. Four marshal-executed evictions at 584 Union Avenue appear in the NYC evictions dataset, the most recent on Jun 4, 2026. The dataset covers executed evictions only, so it undercounts housing court activity: cases that settle or end in a move-out never reach a marshal.
Is 584 Union Avenue rent stabilized?
