Graton Resort Casino Advances $1 Billion Expansion with Vertical Construction Phase

The Federated Indians of Graton Rancheria own and operate Graton Resort and Casino in Rohnert Park, California, where a two-year phase of major vertical construction has now begun as part of the overall $1 billion multi-year expansion. This latest stage focuses on structural work that will continue through late 2026 and sets the foundation for hotel and entertainment elements scheduled to open between 2027 and 2028. Construction teams are prioritizing a new 240-room hotel tower that includes an adults-only pool deck along with expanded suites, while a separate large-format entertainment venue will accommodate concerts and shows once completed. At the same time crews continue the build-out of the non-smoking gaming wing, which features a relocated poker room, additional high-limit areas, and more table games.

Key Infrastructure Additions

A multi-level parking garage equipped with solar panels and EV charging stations forms another core part of the project, supporting the increased capacity expected across the property. Current slot machine counts stand at just over 3,000, with long-term plans targeting up to 6,000 machines as the expansion reaches full scale.

According to the August 2026 construction update, visible structural progress will remain evident through the end of the year, giving visitors and local residents a clear view of the vertical elements rising on site.

Timeline and Phased Development

The two-year vertical construction window aligns with the broader multi-year timeline, allowing the property to maintain operations while adding new facilities. Hotel tower and entertainment venue components are slated for completion in the 2027 to 2028 period, after the parking structure and gaming wing enhancements reach earlier milestones.

Those monitoring the project note that the non-smoking gaming wing build-out proceeds alongside the vertical work, ensuring the poker room relocation and high-limit area expansions integrate smoothly with existing floor layouts. The addition of more table games will occur within this same phase, increasing overall gaming options without interrupting daily operations.

Ownership and Regional Context

The Federated Indians of Graton Rancheria continue to guide the expansion, which represents one of the larger tribal gaming investments currently underway in California. Data from industry reports shows that such phased developments help properties balance ongoing revenue with long-term infrastructure growth.

External references such as the August 2026 construction update and information from the National Indian Gaming Commission provide further background on tribal gaming projects of this scale. These sources detail how similar expansions across multiple states incorporate sustainable elements like solar panels and EV charging to meet modern operational standards.

Long-Term Capacity Goals

Reaching the long-term target of up to 6,000 slot machines will occur gradually as each phase of the expansion comes online. The current count of just over 3,000 machines provides a baseline that the property will build upon once the new hotel tower, entertainment venue, and expanded gaming areas become available to guests.

Conclusion

The August 2026 start of vertical construction at Graton Resort and Casino marks a clear milestone in the $1 billion expansion led by the Federated Indians of Graton Rancheria. With the 240-room hotel tower, adults-only pool deck, entertainment venue, non-smoking gaming wing enhancements, and supporting parking infrastructure all moving forward, the project maintains a structured timeline that extends visible progress through late 2026 and delivers major guest amenities between 2027 and 2028. Slot capacity growth from the current level above 3,000 machines toward the long-term goal of 6,000 will continue as each element reaches completion.
