[6] In early 2015, with administration staff in place and membership on the rise, SF City approached dominant NorCal Premier Soccer League side Ticket Arsenal FC about merging its on-pitch talent, which included many former NCAA Division 1 players and some former Major League Soccer prospects, with SF City's organizational and supporter infrastructure.

[9] The April 25 play-in match between SF City and Cal FC set a US Open Cup preliminary round attendance record, with 1,519 spectators in the stands of the newly refurbished Kezar Stadium.

The club won six and drew two of their fourteen matches in that inaugural season, finishing third in the five-team Central Pacific Division.

At Raimondi Park in Oakland, SF City defeated CD Aguiluchos 4–0 to advance to the second round, where they fell to the USL Championship's Sacramento Republic.
