Graton Resort & Casino Opens Major Expansion Phase in Rohnert Park
The Graton Resort & Casino in Rohnert Park, California, opened the first phase of its billion-dollar expansion on May 4, 2026, and the project delivered a large non-smoking gaming area along with two thousand additional slot machines, a new poker room, high-limit gaming sections, and four new restaurants, while further hotel wings and a theater remain scheduled for completion in 2027.
Observers note that the resort, operated by the Federated Indians of Graton Rancheria, has grown steadily since its original opening, and this latest investment continues that trajectory by focusing first on expanded gaming capacity and dining options before adding more overnight accommodations and entertainment venues.
Key Additions in the Initial Phase
The new non-smoking gaming floor covers a substantial footprint and houses the two thousand slot machines, while adjacent spaces include the poker room that features multiple tables for various games and the high-limit area designed for players seeking elevated stakes, and these facilities connect directly to the four restaurants that offer diverse menus ranging from casual fare to upscale dining experiences.
Construction crews completed the gaming and restaurant portions ahead of the May 4 opening date, which allowed the resort to begin operations without delay, and visitors who arrived on the first day encountered modern interiors with updated lighting, improved ventilation systems, and streamlined layouts intended to enhance flow between gaming zones and dining outlets.
Background on the Overall Project
The full expansion carries a total price tag of one billion dollars and unfolds across multiple years, beginning with the gaming and restaurant elements that debuted in May 2026, and continuing with additional hotel towers plus a dedicated theater venue slated for 2027, according to project timelines released by the resort.
Planners divided the work into distinct phases to minimize disruption to existing operations, and the first stage concentrated on revenue-generating spaces that could open quickly while later stages address lodging and entertainment infrastructure, a sequencing approach that aligns with similar large-scale casino developments across the western United States.
Regulatory filings with the California Gambling Control Commission documented the scope of the expansion, and those documents detail square footage allocations, machine counts, and compliance measures for the new non-smoking environment, which meets updated air quality standards required for enclosed gaming spaces.
Operational Details and Guest Experience
Staff at the resort prepared for the May opening by hiring additional dealers, servers, and floor supervisors to manage the increased capacity, and training programs emphasized the new poker room procedures along with high-limit protocols that include dedicated security and cash-handling stations.
Four restaurants opened alongside the gaming areas, each with distinct themes and operating hours that extend late into the evening to accommodate overnight visitors, while the overall layout positions dining outlets near both the main gaming floor and the new non-smoking section to encourage seamless movement between activities.
Transportation upgrades around the property include expanded parking structures and improved shuttle routes from nearby highways, elements that support the higher volume of guests expected once the full project reaches completion in 2027.
Future Phases Scheduled for 2027
Hotel wings planned for the following year will add hundreds of new rooms and suites, increasing overnight capacity and allowing the resort to host larger conventions or extended-stay guests, while the theater component will feature a performance space suitable for concerts, comedy shows, and special events that draw regional audiences.
Design renderings released by the development team show modern architectural lines that complement the existing structures, and construction permits filed with Sonoma County outline timelines that target a mid-2027 debut for both the lodging additions and the entertainment venue.
Conclusion
The May 4, 2026, opening marks the first tangible step in the one-billion-dollar expansion at Graton Resort & Casino, delivering immediate increases in gaming options and dining choices while setting the stage for further growth in 2027, and the phased approach keeps operations running smoothly as each segment comes online.
