Graton Resort Casino Completes First Phase of Major California Expansion

The Graton Resort & Casino in Rohnert Park opened its largest expansion to date on or around May 29 2026 when a new 144,000-square-foot smoke-free district welcomed visitors for dining gaming and entertainment and this addition brings nearly 2,000 new slot machines while creating more than 450 jobs in Sonoma County.

Developers designed the space as the initial stage of a longer multi-year project that will eventually add a hotel tower an adults-only pool and a theater yet the current opening already delivers several distinct venues including the AYA rooftop restaurant led by Chef Roy Ellamar along with Playbook Sports Bar and SoCo Dough Co.

Details of the New District

Construction teams finished the smoke-free area which covers 144,000 square feet and integrates gaming floors with restaurants and entertainment spaces so guests can move between activities without leaving the controlled environment and the project added nearly 2,000 slot machines that expand the overall gaming capacity at the property.

AYA sits on the rooftop and features menus developed by Chef Roy Ellamar while Playbook Sports Bar provides large screens and casual dining and SoCo Dough Co. focuses on fresh bakery items and quick service and these venues operate within the larger smoke-free zone that distinguishes the expansion from earlier sections of the casino.

Employment and Regional Effects

Officials reported that the expansion created over 450 new positions ranging from gaming staff to culinary teams and hospitality roles and these opportunities contribute to the local economy in Sonoma County where the resort has operated since its original opening and data from regional workforce reports show steady demand for such positions in the hospitality sector.

Community leaders note that the jobs come with training programs tied to the new facilities so employees gain skills that support both immediate operations and future phases of development and the addition of nearly 2,000 slot machines increases the scale of gaming activity which in turn supports ongoing employment needs.

Future Phases of Development

Planners have outlined additional elements that will follow in later years including a hotel tower an adults-only pool and a dedicated theater and these features will build on the foundation established by the current 144,000-square-foot district so the resort continues to grow its offerings over time.

The multi-year timeline allows for phased construction that minimizes disruption to existing operations while each stage adds new amenities that attract different segments of visitors and observers point out that the approach mirrors strategies used at other large tribal gaming properties across California.

Context Within California Gaming

Graton Resort Casino operates as a tribal gaming facility and its expansion aligns with broader trends in the state where properties invest in updated amenities to meet changing guest preferences and the decision to make the new district entirely smoke-free reflects health regulations that many venues now follow.

According to industry reports from Yogonet the project marks the first major addition since the resort began operations and the scale of nearly 2,000 new slot machines places it among the larger single-phase increases recorded at California casinos in recent years.

State gaming oversight through the California Gambling Control Commission tracks such developments to ensure compliance with tribal-state compacts and local economic data from Sonoma County shows consistent growth in tourism-related revenue that supports infrastructure and services around Rohnert Park.

Conclusion

The opening of the smoke-free district on or around May 29 2026 represents a significant step for Graton Resort Casino as it adds substantial gaming capacity new dining and entertainment options and hundreds of jobs while setting the stage for further construction that includes a hotel tower adults-only pool and theater and the phased approach allows the property to integrate these changes gradually into its existing operations in Sonoma County.
