Graton Resort & Casino Advances Vertical Construction in $1 Billion Expansion Plan

The Federated Indians of Graton Rancheria have initiated a two-year phase of major vertical construction at Graton Resort & Casino in Rohnert Park, California as part of the property's ongoing $1 billion multi-year expansion, and this work follows the May 4, 2026 opening of a dedicated non-smoking wing while targeting enhanced hospitality and entertainment capacity through 2028.

Project Scope and Timeline

Construction crews have begun erecting the structural framework for a new 240-room hotel tower that will include an adults-only pool area along with a large-format entertainment venue designed to host concerts and events, and these elements form the core of the current vertical phase that will continue through 2028 according to project updates released in August 2026.

The expansion builds directly on earlier horizontal development work completed in prior years, and observers note that the shift to vertical construction marks a transition from site preparation and foundation work to the visible addition of new height and guest amenities on the property.

Gaming Floor Growth Targets

Current slot machine inventory stands at just over 3,000 units, and the long-term master plan calls for growth to as many as 6,000 slots once all phases reach completion, though the immediate two-year vertical stage focuses primarily on the hotel tower, pool, and entertainment venue rather than additional gaming floor square footage.

Project documents indicate that gaming expansion will occur in measured increments aligned with demand and regulatory approvals, while the hotel and entertainment components receive priority during this specific construction window.

Recent Milestones and Ongoing Work

The non-smoking wing that opened on May 4, 2026 added dedicated space for guests seeking smoke-free gaming and lodging environments, and this addition serves as the immediate foundation for the vertical construction now underway because it freed up operational areas for new tower integration and guest circulation planning.

Contractors have mobilized cranes and material staging areas on site, and engineers continue to coordinate utility connections and structural tie-ins between the existing resort structures and the rising hotel tower while maintaining full operations for current visitors.

Ownership and Regional Context

The Federated Indians of Graton Rancheria own and operate the resort, and tribal leadership has coordinated the multi-year investment to strengthen the property's position within the Northern California gaming and hospitality market through a combination of lodging, entertainment, and gaming capacity increases.

Local planning records show that permits for the vertical phase were secured following environmental reviews and traffic studies, and construction activity is scheduled to proceed in sequenced stages that minimize disruption to the existing resort footprint.

Future Phases and Capacity Additions

Once the 240-room tower and entertainment venue reach completion, subsequent work will address further gaming floor expansion and supporting infrastructure, and project timelines project that the full $1 billion investment will unfold across additional years beyond the current two-year vertical window.

Design specifications for the adults-only pool emphasize private access and resort-style amenities, while the large-format entertainment space is sized to accommodate major touring productions and large-scale events that draw regional audiences.

Conclusion

The August 2026 start of vertical construction at Graton Resort & Casino represents the latest milestone in a carefully sequenced $1 billion expansion that already delivered a non-smoking wing in May 2026 and now moves into building the 240-room hotel tower, adults-only pool, and entertainment venue while preparing for long-term growth from 3,000-plus slots toward a 6,000-unit target. Construction continues under tribal ownership with coordinated phases that maintain ongoing resort operations throughout the multi-year timeline.
