Graton Resort & Casino Enters Key Vertical Construction Phase in August 2026

The Federated Indians of Graton Rancheria own Graton Resort & Casino in Rohnert Park, California and the tribe has initiated a two-year stretch of major vertical construction that forms part of its larger $1 billion multi-year expansion program, with crews focusing on structural work that will remain visible through late 2026.
Observers note that the project centers on a new 240-room hotel tower which will feature an adults-only pool deck along with expanded suites, while a large-format entertainment venue designed for concerts and shows takes shape nearby, and these elements sit alongside continued development of the non-smoking gaming wing that includes a relocated poker room, additional high-limit areas, and more table games overall.
Hotel Tower and Entertainment Components Drive the Build
The hotel tower rises as one of the most prominent elements in the current phase, delivering 240 rooms that incorporate an adults-only pool deck and a selection of expanded suites, while construction teams coordinate the parallel erection of the large-format entertainment venue intended to host concerts and shows once it opens in the 2027–2028 window.
Those tracking the schedule report that visible structural progress on both the tower and the venue will continue through the end of 2026, after which finishing work will shift focus toward interior fit-outs and operational readiness for the later target dates.
Gaming Wing Expands Alongside Infrastructure Upgrades

The non-smoking gaming wing receives further build-out during this period, with the relocated poker room, new high-limit areas, and increased numbers of table games all advancing in tandem, while the current slot count stands just over 3,000 and long-term plans target growth to as many as 6,000 machines across the property.
Infrastructure work runs parallel to the gaming and hospitality elements, as crews construct a multi-level parking garage that incorporates solar panels and electric vehicle charging stations, providing the support systems required once the expanded facilities reach full operation.
Timeline and Current August 2026 Status
Reports from August 2026 indicate that the two-year vertical construction phase has now begun in earnest, with the hotel and entertainment components scheduled to come online between 2027 and 2028, while the broader $1 billion expansion continues beyond that horizon to accommodate the projected slot machine growth and additional amenities.
According to the National Indian Gaming Commission, tribal gaming facilities such as Graton Resort & Casino follow established regulatory frameworks that govern construction timelines and operational expansions across Indian Country. Industry data compiled by the American Gaming Association shows that multi-year projects of this scale typically unfold in distinct phases that allow properties to maintain existing revenue streams while new structures take shape.
Conclusion
The August 2026 update confirms that Graton Resort & Casino has moved into the active vertical construction stage of its $1 billion expansion, with the 240-room hotel tower, entertainment venue, non-smoking gaming additions, and supporting parking infrastructure all progressing on the published schedule that extends visible work through late 2026 and opening dates into 2027–2028.
