Graton Resort Casino Advances Major Expansion With New Gaming Spaces Opening in 2026

Graton Resort & Casino in Rohnert Park, California continues to move forward with its $1 billion expansion project that transforms the property into a larger destination resort, and the first phase opens on May 4, 2026 with expanded gaming space that includes roughly 2,000 additional slot machines along with dedicated non-smoking areas.

Observers note that this initial stage marks the beginning of several planned additions while the property already employs hundreds of new staff members to support growing operations, and those additions include a 200-plus room hotel tower plus a major entertainment venue that will follow in subsequent phases.

First Phase Details and Timeline

The May 2026 opening brings new gaming floors that feature the additional slots and non-smoking sections, while full build-out of that non-smoking wing later incorporates expanded poker rooms, a sports bar, more dining options, and additional table games, and the overall project targets a total capacity of 6,000 machines across the property.

Construction crews work steadily through the spring of 2026 to meet the May 4 deadline, and project managers coordinate deliveries of new equipment and finishes so that the non-smoking areas open alongside the slot machines, and this coordinated approach allows the resort to maintain existing operations during the transition.

Subsequent Development Phases

After the first phase becomes operational, attention shifts to the hotel tower that adds more than 200 rooms and brings new lodging capacity to the site, while the entertainment venue takes shape as a space for concerts and events that draw regional visitors, and those elements combine with further gaming growth that pushes machine totals toward the 6,000 target.

Planners schedule the non-smoking wing completion to include the poker expansion and sports bar alongside table game additions, and each piece connects to the larger goal of creating a full-service resort that offers lodging, entertainment, and varied gaming under one roof.

Workforce Expansion and Operations

Recent hiring brought hundreds of new employees to the property ahead of the May 2026 opening, and those staff members receive training on the expanded gaming areas as well as the new hospitality features that come online in later stages, and the increased workforce supports both daily operations and the phased rollout of amenities.

Human resources teams continue recruitment efforts into June 2026 to fill remaining positions tied to the hotel tower and entertainment venue, while existing team members adapt to the larger scale of the resort, and payroll data shows steady growth that aligns with the construction timeline.

Project Scope and Long-Term Goals

The $1 billion investment covers multiple building phases that together reposition Graton Resort & Casino as a premier Northern California destination, and project documents outline the sequence from gaming expansion through hotel and entertainment additions that ultimately support the 6,000-machine capacity, and each milestone builds on the previous one without interrupting core business activities.

Design teams incorporate non-smoking environments throughout the new wing to meet guest preferences, and those spaces integrate with expanded dining and bar options that serve both gaming and entertainment visitors, while the overall layout keeps circulation clear between phases so that construction and operations proceed side by side.

Conclusion

The expansion at Graton Resort & Casino follows a clear sequence that begins with the May 4, 2026 gaming additions and continues through hotel, entertainment, and further gaming growth, and the hiring of hundreds of new employees prepares the property for increased visitor volume across all phases, while the $1 billion commitment supports the transformation into a larger integrated resort destination in Rohnert Park.
