Graton Resort and Casino Moves Into Vertical Construction Phase of Billion-Dollar Expansion

Graton Resort and Casino in California continues its $1 billion multi-year expansion with a clear shift from recent gaming-floor additions to major vertical construction phases that include a 240-room hotel tower, a large-format entertainment venue, and additional gaming space aimed at reaching up to 6,000 slots. The property currently operates just over 3,000 slots, and observers note visible progress on supporting infrastructure such as a new parking garage. According to a construction update published in August 2026, work remains on track through late 2026 and into the following years.

Recent Gaming-Floor Additions Set the Stage

Earlier phases of the project focused on horizontal expansions that added new gaming space, including the non-smoking wing opened on May 4. Those additions increased capacity and prepared the resort for further growth while maintaining operational continuity. Developers have now transitioned resources toward vertical elements that will rise above the existing structure, bringing new hotel rooms and entertainment options to the site.

Vertical Construction Takes Center Stage

Construction crews are advancing the 240-room hotel tower alongside the large-format entertainment venue, both of which form core components of the overall expansion. The hotel tower will add substantial lodging capacity, while the entertainment venue is designed to host large-scale events that complement the casino floor. Further gaming growth will push the total slot count toward the 6,000 mark, building on the current inventory of just over 3,000 machines. Infrastructure work, particularly the parking garage, shows clear advancement and is expected to remain active through late 2026 before carrying into 2027 and 2028.

Infrastructure Timeline and Milestones

Progress reports from August 2026 highlight steady advancement on foundational elements that support the larger vertical structures. The parking garage stands out as one of the most visible projects underway, with crews addressing structural and access requirements that will serve both hotel guests and entertainment attendees. Timelines indicate these infrastructure improvements will continue rolling forward into 2027 and 2028, aligning with the phased rollout of the hotel tower and entertainment venue. Such sequencing allows the resort to maintain existing operations while new components come online.

Expanded Gaming and Entertainment Offerings

The push toward 6,000 slots represents a significant increase from the present total, and developers are coordinating this growth with the new vertical construction. The large-format entertainment venue will provide additional programming that draws visitors to the expanded gaming areas. Observers tracking the project note that the combination of hotel rooms, entertainment space, and increased slot inventory creates a more integrated destination capable of handling higher visitor volumes over multiple years.

Conclusion

Graton Resort and Casino's $1 billion expansion has entered its vertical construction stage, with the 240-room hotel tower, large-format entertainment venue, and gaming growth to 6,000 slots forming the central elements of the next phase. Current slot counts exceed 3,000, and infrastructure such as the parking garage continues to advance according to the August 2026 update, with work projected through late 2026 and into 2027-2028. The project maintains its multi-year trajectory while shifting focus from floor-level additions to the vertical structures that will define the resort's future footprint.
