Graton Resort Casino Moves Into Next Stages of Billion-Dollar Expansion
The Federated Indians of Graton Rancheria continue to drive forward with the remaining segments of their one-billion-dollar multi-year project at Graton Resort Casino in Rohnert Park, California, after the May 4, 2026 debut of a new 144,000-square-foot smoke-free gaming floor that introduced roughly 2,000 slot machines along with expanded poker and high-limit sections plus three fresh dining outlets. Attention has now turned toward construction of a 200-plus-room hotel tower, a large-scale entertainment venue, completion of the non-smoking wing, further dining and hospitality additions, and increased gaming capacity overall.
According to industry reports the smoke-free floor opened on schedule and immediately integrated new amenities such as the AYA rooftop restaurant, Playbook Sports Bar, and SoCo Dough Co., each designed to complement the added gaming space while maintaining separate ventilation and access points from the original smoking areas. The project timeline places the current work squarely in June 2026, when crews have begun site preparation for the hotel tower and entertainment complex while contractors finish interior build-outs in the non-smoking sections already under roof.
Key Elements of the Remaining Development
Observers familiar with the expansion note that the hotel tower will add more than 200 guest rooms and connect directly to both the new gaming floor and the entertainment venue, creating a single integrated complex that allows visitors to move between lodging, gaming, dining, and live performances without leaving the property. Plans also call for full completion of the non-smoking wing, which will house additional table games and slot banks once interior finishes and regulatory inspections conclude.
Additional dining and hospitality outlets remain on the schedule, although specific names and opening dates have not yet been released; project documents indicate these venues will occupy ground-level and mezzanine spaces adjacent to the hotel lobby and entertainment hall. Expanded gaming capacity will come through phased installation of more machines and tables once the new tower and venue structures reach operational readiness.
Workforce Expansion Supports Ongoing Construction
Since January the casino has brought on 500 new employees across gaming, food service, security, and facilities departments, and recruitment continues for another 300 positions needed to staff the hotel tower and entertainment venue once they open. Hiring managers have focused on local candidates from Sonoma County and surrounding areas, with training programs already underway for dealers, hospitality staff, and technical crews who will maintain the enlarged property.
Those tracking tribal gaming operations point out that the Federated Indians of Graton Rancheria have coordinated workforce growth with construction milestones, ensuring trained personnel are available as each phase reaches completion; this approach has kept the project on its published timeline while meeting state and tribal regulatory requirements for staffing levels.
Regulatory and Community Context
California gaming regulators have reviewed and approved the latest construction permits for the hotel tower and entertainment venue, confirming compliance with environmental and safety standards established for tribal casino expansions. Community liaison updates released in early June 2026 indicate ongoing coordination with Rohnert Park city officials regarding traffic management during the construction period and long-term economic contributions once the full project concludes.
Project records show that the overall one-billion-dollar investment covers both the recently opened gaming floor and the structures still under development, with phased funding released as each segment meets inspection benchmarks. The multi-year schedule allows the tribe to maintain continuous operations while adding capacity in measured increments.
Conclusion
Graton Resort Casino has now transitioned from the May 4, 2026 gaming-floor opening into the active construction phase of its remaining expansion elements, including the 200-plus-room hotel tower, major entertainment venue, non-smoking wing completion, and supporting hospitality additions. With 500 employees already hired and recruitment for 300 more positions active, the operation continues to scale its workforce alongside physical development. All work remains on the established multi-year timeline backed by the one-billion-dollar investment from the Federated Indians of Graton Rancheria.
