Tulalip Resort Casino Finishes Three-Year Expansion Project on Washington Reservation

The Tulalip Resort Casino, located on the Tulalip Tribes’ reservation in Washington, has completed a three-year expansion that added 70,250 square feet to the property, and observers note the gaming floor now measures 270,250 square feet while the total slot machine count exceeds 2,600 after more than 400 new units were installed during the project that wrapped up in recent months.

Project Timeline and Scope

Construction began three years earlier and proceeded in phases that allowed the facility to remain open throughout the work, while the expanded gaming floor opened to the public in July 2025 and the remaining elements such as bar renovations and restaurant upgrades reached completion later, according to project records cited in local coverage.

Data from teh development shows the square footage increase directly supported the addition of new gaming positions along with support areas, and the overall build incorporated cultural design elements drawn from Tulalip Tribes heritage that appear throughout the new and renovated spaces.

Added Gaming and Amenities

The expanded floor includes more than 400 additional slot machines that bring the total inventory past 2,600 units, while a renovated high-limit slots room received updated finishes and equipment as part of the same initiative, and new North Bar and Center Bar amenities now provide additional seating and service points for guests.

Restaurant upgrades form another component of the completed work, and these changes occurred alongside the installation of cultural motifs integrated into flooring, wall treatments, and lighting fixtures across the enlarged gaming area.

Those who tracked the construction timeline report that the July 2025 opening of the enlarged gaming floor marked a key milestone, after which crews finalized the bar additions, high-limit room updates, and remaining restaurant improvements that closed out the full scope of work.

Design and Operational Context

Cultural design elements appear in multiple areas of the finished project, and these features connect the physical expansion to the history of the Tulalip Tribes while the operational changes focus on expanded slot capacity and refreshed guest amenities that became available in stages through 2025 and into 2026.

Figures released about the project indicate the 70,250-square-foot addition accounts for the growth in gaming positions and support facilities, whereas the pre-expansion footprint supported a smaller total before the new slot machines and bar areas came online.

According to reports covering the October 2026 period, the overall project has now concluded, and the casino operates with the increased gaming floor size and updated amenities that resulted from the multi-year effort on the Washington reservation.

Conclusion

The completed expansion at Tulalip Resort Casino stands as a record of the three-year construction program that delivered additional slot machines, new bar amenities, a renovated high-limit area, restaurant improvements, and integrated cultural elements, with the gaming floor reaching 270,250 square feet and the total slot count exceeding 2,600 units after the July 2025 public opening of the enlarged space and final project closeout in recent months.
