Graton Resort & Casino Advances Its Billion-Dollar Expansion in Rohnert Park

Graton Resort & Casino in Rohnert Park, California, continues its $1 billion expansion project, which entered a new phase following the May 4, 2026 opening of additional gaming space that includes a 144,000 square foot non-smoking wing along with approximately 2,000 new slot machines, while further developments remain scheduled over the next 24 to 36 months.

The expansion has already produced tangible results in the form of new employment opportunities, with 500 additional staff members hired since January and recruitment efforts underway for 300 more positions to support the growing operation.

Recent Milestones in the Expansion Timeline

The May 4, 2026 addition marked a significant step forward in the overall project, as the new non-smoking wing provided immediate capacity increases that allow the resort to accommodate more visitors while addressing demand for smoke-free environments, and this phase also introduced thousands of slot machines that expanded the gaming floor substantially.

Observers note that the opening aligned with ongoing construction activities, and the resort has maintained operations throughout the build-out, which helps sustain revenue streams while crews complete subsequent stages of the development.

Planned Developments Over the Coming Years

Over the next 24 to 36 months, the project calls for construction of a new hotel tower with more than 200 rooms, creation of a major entertainment venue designed for concerts and other large-scale events, and completion of the non-smoking casino wing that will feature a relocated poker room, a sports bar, high-limit slots, and additional dining options, while further restaurants and gaming capacity growth will push the total machine count toward 6,000.

These elements build directly on the foundation established by the May 2026 opening, and project timelines indicate phased rollouts that allow each component to integrate with existing facilities without disrupting daily operations, according to details shared in industry updates.

Construction crews continue work on the hotel tower and entertainment venue, where structural elements have begun to take shape, and these additions aim to diversify the resort's offerings beyond gaming by attracting a broader range of guests interested in lodging and live performances.

Employment Growth and Operational Impacts

The hiring surge that added 500 employees since January reflects the increased staffing needs created by the expanded gaming areas and support services, while the current recruitment drive for 300 more positions focuses on roles across gaming, hospitality, and food service departments to handle anticipated visitor growth.

Workforce expansion has occurred steadily as new facilities come online, and training programs have accompanied these hires to ensure staff members can manage the larger scale of operations effectively, which supports consistent service levels during the transition period.

Context Within California's Gaming Landscape

Graton Resort & Casino operates under tribal gaming compacts in California, where such expansions require coordination with state regulatory frameworks that oversee machine counts and facility approvals, and the push toward 6,000 total machines aligns with limits established through those agreements.

Reports from industry tracking sources detail how the project has progressed in stages, and similar developments at other tribal properties in the state show how incremental growth in gaming capacity often pairs with investments in non-gaming amenities like hotels and entertainment spaces.

Looking Ahead to Mid-2026 Progress

As of June 2026, construction activity remains visible around the property, with crews advancing work on the hotel tower and entertainment venue while the newly opened wing operates at full capacity, and this period allows the resort to assess visitor response to the added slot machines and non-smoking areas before the next phases launch.

Additional restaurants and refinements to the non-smoking wing, including the poker room relocation and sports bar integration, stay on schedule for rollout within the 24- to 36-month window, which positions the full expansion to reach completion by approximately 2028 or 2029.

Conclusion

The $1 billion expansion at Graton Resort & Casino represents a multi-year commitment that has already delivered new gaming space and employment gains, with the May 2026 opening serving as a key milestone that sets the stage for the hotel tower, entertainment venue, and further capacity increases ahead.

Through continued hiring and phased construction, the project maintains momentum toward its goal of 6,000 total machines and enhanced amenities, which together aim to strengthen the resort's position in the regional market while adhering to established regulatory guidelines.
