Seattle Sounders Training Facility Gets $12M Upgrade

The Seattle Sounders FC confirmed this week that construction crews have begun work on a full overhaul of the main training building at Starfire Sports Center in Tukwila.

The timing aligns with the club's push through the middle of the 2026 MLS season, where tighter recovery space and updated medical areas are expected to help players handle a run of home and away fixtures that starts in late July.

Starfire sits along the Duwamish River corridor, a short drive from the club's main offices in the SoDo neighborhood near Lumen Field. Staff already shuttle players between the two sites on game days, and the new layout will cut that travel time by adding on-site video analysis rooms and expanded weight areas.

Numbers behind the build

Project documents filed with the City of Tukwila list a total budget of $12 million, with $4.2 million earmarked for three new turf fields and $2.8 million for the medical wing. The work is scheduled to finish by September 15, 2026, which would give the first team a full month of use before the playoff push.

Sounders officials have said the upgrades will also open limited public viewing hours on weekends once construction ends, a change from the current closed-door policy at the complex.

Next steps for fans and players

Season-ticket holders will receive an email next month with details on how to reserve spots for the first open-house weekend after the fields reopen. The club has not yet set ticket prices for those sessions but confirmed they will stay under $25 per person to keep access broad.

Players are already using temporary trailers on the site while the main building is gutted, a setup that team trainers say has not slowed summer conditioning work.
