Graton Resort & Casino Launches Vertical Construction Phase in $1 Billion Expansion

Graton Resort & Casino in Rohnert Park, California, owned by the Federated Indians of Graton Rancheria, has entered a two-year phase of major vertical construction as part of its ongoing $1 billion multi-year expansion, and observers note visible structural progress expected through late 2026 with hotel and entertainment elements slated for 2027–2028. This marks a shift from groundwork to upward builds that include a new 240-room hotel tower featuring an adults-only pool deck and expanded suites along with a large-format entertainment venue designed for concerts and shows.

Project Scope and Key Components

The expansion encompasses continued build-out of the non-smoking gaming wing that will include a relocated poker room, high-limit areas, and additional table games while infrastructure upgrades feature a multi-level parking garage equipped with solar panels and EV charging stations. Current slot machines number just over 3,000 with long-term targets reaching up to 6,000, and these elements combine to support increased capacity across gaming, lodging, and visitor amenities at the property.

According to the August 2026 construction update, crews have transitioned into vertical work that raises the hotel tower and entertainment space above ground level, and this follows earlier site preparation that established foundations for the parking structure and gaming additions. The timeline positions substantial completion of core vertical elements by the end of 2026 while full operational readiness for the hotel and venue stretches into the following two years.

Hotel Tower and Entertainment Developments

The 240-room hotel tower incorporates an adults-only pool deck along with expanded suites that provide upgraded accommodations, and this addition addresses growing demand for on-site lodging connected directly to the casino floor. Construction crews focus on framing and structural systems in this phase, which allows for integration of the pool area and suite layouts as work advances through 2026.

The large-format entertainment venue receives simultaneous attention during this vertical phase, and it will host concerts and shows once completed in the 2027–2028 window. Planners designed the space to accommodate major performances while connecting to existing resort pathways, which supports seamless guest movement between gaming areas, the new hotel, and event facilities.

Gaming Wing and Infrastructure Upgrades

Build-out continues on the non-smoking gaming wing where the poker room relocates to a dedicated space, high-limit areas expand, and more table games come online over the coming months. These changes align with the slot count growth from the current figure just over 3,000 toward the long-term goal of 6,000 machines, and the phased approach keeps operations running while construction proceeds in adjacent sections.

The multi-level parking garage forms a critical infrastructure piece that includes solar panels and EV charging stations, and this supports increased visitor volume once the hotel and entertainment components open. Work on the garage integrates with the vertical construction timeline, allowing coordinated delivery of power and access features alongside the main resort additions.

Timeline and Current Progress

Reports from August 2026 indicate that structural progress on the hotel tower and entertainment venue remains on schedule with visible framework rising at the site, and this follows initial groundwork that prepared the area for upward builds. The two-year vertical construction window extends through late 2026 while final finishes and openings for guest-facing elements occur in 2027 and 2028.

Those tracking the project note that the Federated Indians of Graton Rancheria coordinate the expansion to maintain continuous casino operations during the build, and slot machines plus table games stay available throughout the non-smoking wing improvements. Data from the property shows steady visitor interest that justifies the capacity increases planned across lodging, entertainment, and gaming.

Conclusion

The $1 billion expansion at Graton Resort & Casino advances through its vertical construction phase with clear milestones set for hotel tower completion, entertainment venue readiness, gaming wing enhancements, and supporting infrastructure like the solar-equipped parking garage. Observers track progress through late 2026 as the property moves toward full realization of its long-term slot targets and guest amenities in the years ahead, and this development reflects ongoing investment by the Federated Indians of Graton Rancheria in the Rohnert Park location.
