Graton Resort & Casino Advances Two-Year Vertical Construction Phase in $1 Billion Expansion

The Graton Resort & Casino in California has entered a two-year phase of major vertical construction that forms part of its $1 billion multi-year expansion program, and this stage focuses on building upward structures while integrating new amenities across the property. Construction crews are now raising the framework for a 240-room hotel tower that will include an adults-only pool deck plus expanded suites, and the tower stands as one of the central vertical elements scheduled for completion within the current timeline. Work on the large-format entertainment venue designed for concerts and shows has also begun, with foundation and structural work progressing alongside the hotel tower. Current slot machine counts sit just over 3,000, yet the long-term target calls for capacity reaching up to 6,000 machines once all phases conclude. The non-smoking casino wing that opened in May 2024 continues to operate as crews handle parallel upgrades.

Project Timeline and Ongoing Elements Through 2028

Relocation of the poker room, installation of high-limit gaming areas, and upgrades to the parking garage represent additional components that remain active through 2026-2028. These elements proceed in coordinated stages so that existing operations experience minimal disruption while vertical construction advances. Observers note that the two-year vertical phase marks a shift from earlier groundwork toward the visible rise of new buildings on the site.

Data from project updates shows that the overall expansion spans multiple years, with the current vertical push representing a concentrated period of structural work. The entertainment venue will feature large-scale seating and staging capabilities suited for concerts and shows, and its design integrates with the hotel tower to create a connected guest experience. Parking garage improvements include expanded capacity and improved access points that align with expected increases in visitor volume once the new facilities open.

Gaming Expansion Details and Facility Upgrades

The gaming growth component targets an increase from the present level of just over 3,000 slots toward the long-term goal of 6,000 machines, and this expansion occurs in phases that allow incremental additions without closing sections of the floor. High-limit gaming areas receive dedicated space within the updated layout, while the relocated poker room moves to a position that improves traffic flow between gaming zones. The non-smoking wing, already operational since May 2024, provides a model for future non-smoking sections planned as part of the broader growth. Construction schedules indicate that vertical work on the hotel tower and entertainment venue will continue through the next two years, after which finishing work and interior fit-outs extend into subsequent periods. Parking garage upgrades include structural reinforcements and new levels that support the increased number of guests expected once the 240-room tower and entertainment venue reach full operation.

Integration of New Amenities With Existing Operations

The adults-only pool deck attached to the hotel tower adds a distinct amenity that complements the expanded suites, and this feature receives direct connection to the tower's upper levels. The entertainment venue's large-format design accommodates concerts and shows with flexible staging, and its location near the hotel supports combined stays for visitors attending events. All elements tie into the $1 billion investment framework that guides the multi-year timeline.

Updates released in August 2026 confirm that the vertical construction phase remains on schedule, with steel and concrete work visible on both the hotel tower and entertainment venue. The poker room relocation and high-limit gaming additions continue as interior projects that run parallel to the exterior vertical builds. Garage improvements focus on both capacity and circulation to handle projected demand through 2028.

Conclusion

The Graton Resort & Casino expansion now centers on vertical construction that will deliver the 240-room hotel tower, adults-only pool deck, expanded suites, large-format entertainment venue, and increased gaming capacity over the coming years. Current slot counts exceed 3,000 with a target of 6,000, while the non-smoking wing opened in May 2024 and additional upgrades to the poker room, high-limit areas, and parking garage proceed through 2026-2028. According to the construction update available at 500 Nations, these coordinated phases form the active core of the $1 billion program.
