Graton Resort & Casino Enters Major Vertical Construction Phase in California Expansion

The Federated Indians of Graton Rancheria own Graton Resort & Casino in Rohnert Park, California, and this property has entered a two-year phase of major vertical construction that forms part of its overall $1 billion multi-year expansion plan, according to an August 2026 construction update.

Construction crews have shifted focus to vertical elements after earlier site preparation work, and observers note that visible structural progress will continue through late 2026 while hotel and entertainment components reach completion in 2027 and 2028.

Hotel Tower and Guest Amenities Take Shape

A new 240-room hotel tower stands at the center of the current phase, and it will feature an adults-only pool deck along with expanded suite options that increase overall guest capacity. Project details indicate the tower will connect directly to existing casino facilities, which allows visitors to move between gaming areas and accommodations without leaving the property. The design incorporates additional high-end room categories that target both leisure travelers and those attending events at the new entertainment venue.

Entertainment Venue and Gaming Wing Updates

Alongside the hotel, builders are developing a large-format entertainment venue designed to host concerts and shows, and this space will provide a dedicated performance area separate from the main casino floor. At the same time, work continues on the non-smoking gaming wing where crews are relocating the poker room, adding high-limit areas, and installing more table games to expand player options. These changes build on the existing layout while creating distinct zones for different types of gaming activity.

The current slot machine count exceeds 3,000 units, yet long-term plans call for growth up to 6,000 machines once all phases finish, and the expansion timeline aligns infrastructure upgrades with these capacity increases.

Infrastructure Improvements Support Long-Term Operations

A multi-level parking garage forms another key element of the project, and this structure will include solar panels plus electric vehicle charging stations to meet modern operational and environmental requirements. The garage addresses increased visitor numbers expected after the hotel and entertainment additions open, while the sustainable features reflect broader industry trends toward energy-efficient development. Construction schedules show these infrastructure elements advancing in parallel with the hotel tower and venue work.

By August 2026 crews had already completed significant foundation and framing tasks for several structures, and project managers report steady advancement across multiple sites within the resort footprint. Those following the development note that the two-year vertical construction window will deliver the most visible changes yet seen at the property.

Timeline and Phased Completion Details

Structural progress on the hotel tower and parking garage remains on track for substantial completion by the end of 2026, while final finishes for guest rooms, the adults-only pool deck, and the entertainment venue extend into 2027 and 2028. The phased approach allows portions of the non-smoking gaming wing to open earlier even as other elements continue under construction. This sequencing minimizes disruption to ongoing casino operations during the expansion period.

Industry reports from the region show similar large-scale casino projects often follow comparable multi-year timelines, and the Graton development fits within that established pattern of gradual capacity growth and amenity additions.

Conclusion

The current phase at Graton Resort & Casino represents a significant step forward in the overall $1 billion expansion, and updates from August 2026 confirm that vertical construction has begun in earnest. Hotel tower elements, the entertainment venue, gaming wing improvements, and supporting infrastructure such as the solar-equipped parking garage will reshape the property over the next several years. Completion of key components between 2027 and 2028 will bring the full scope of planned changes into operation while maintaining the resort's existing gaming and hospitality functions throughout the process.
