Graton Resort & Casino Launches Vertical Construction on $1 Billion Expansion Project
Graton Resort & Casino in California has moved into a two-year stretch of major vertical construction as part of its ongoing $1 billion multi-year expansion, and observers note that visible progress on several key structures will continue through late 2026. The project centers on a 240-room hotel tower that will feature an adults-only pool deck along with various suite options, while a large-format entertainment venue designed for concerts and shows takes shape alongside it. Current slot machine counts sit just over 3,000, yet the long-term target calls for as many as 6,000 machines once all phases reach completion, and the expansion also includes a relocated and enlarged poker room, a new high-limit area, additional table games, fresh dining concepts, and further work on the parking garage that incorporates solar panels and EV charging stations.
Project Timeline and Recent Milestones
The non-smoking wing opened in May 2024, marking an early deliverable within the broader plan, while foundation work and other ground-level preparations have already given way to vertical elements that crews expect to advance steadily over the coming months. Data from project updates shows that the two-year vertical construction window began in mid-2026, and those who have tracked similar tribal casino developments note that hotel tower framing along with venue shell construction will create the most prominent skyline changes between now and the end of 2026. Parking garage improvements, including the addition of solar arrays and electric vehicle charging points, continue in parallel so that the infrastructure keeps pace with the growing guest capacity.
Gaming Floor and Amenities Expansion
Gaming expansion forms a central pillar of the effort, and current figures reveal slot inventory just above the 3,000 mark with plans that stretch toward a long-term ceiling of 6,000 units. The relocated poker room will occupy a larger footprint with upgraded seating and viewing areas, while the new high-limit room and expanded table game offerings aim to broaden the range of experiences available to players. Dining concepts are also advancing, with multiple new outlets scheduled to open in step with the hotel and entertainment venue so that the overall guest journey remains integrated. According to construction reports shared by 500 Nations, crews have already begun vertical framing on the hotel tower, and the entertainment venue will feature flexible seating configurations that can accommodate both intimate performances and larger concert productions.
Those who have followed the project point out that the adults-only pool deck will sit atop one section of the hotel tower, offering a dedicated leisure space separate from family-oriented areas elsewhere on the property. The parking structure itself receives solar panels across portions of its roof, and EV charging stations will increase in number to match rising demand from visitors who arrive with electric vehicles. Research from regional planning documents indicates that these infrastructure upgrades align with broader California energy standards, and the combined effect supports both operational efficiency and guest convenience once the full expansion opens.
Construction Progress Through Late 2026
Visible milestones such as rising steel and concrete on the hotel tower will remain the most noticeable elements through the remainder of 2026, while interior fit-out work on the entertainment venue and gaming expansions proceeds behind the scenes. The two-year vertical phase builds directly on earlier groundwork, and project schedules show that structural completion for the hotel and venue will set the stage for finishing touches that extend into subsequent years. Figures shared in industry briefings confirm that the overall $1 billion investment covers multiple interconnected components, ensuring that gaming, lodging, dining, and parking elements advance in coordinated fashion rather than as isolated additions.
Integration with Existing Operations
Throughout the construction period the existing casino floor continues to operate without interruption, and the non-smoking wing that opened in May 2024 already provides guests with an expanded choice of environments. Additional table games and the high-limit room will come online in phases that minimize disruption, while the poker room relocation occurs once the new space reaches operational readiness. Observers familiar with similar expansions note that phased rollouts of this type allow properties to maintain revenue streams while steadily increasing capacity toward the long-term slot target of 6,000 machines.
Conclusion
The current vertical construction phase at Graton Resort & Casino represents a pivotal stretch within the larger $1 billion expansion, and the combination of hotel tower, entertainment venue, gaming growth, and supporting infrastructure will reshape the property over the next two years. Updates through late 2026 will continue to highlight foundation-to-frame transitions on the hotel and venue, while the non-smoking wing and ongoing parking improvements already demonstrate tangible progress from earlier stages. Those tracking the project can expect further visible milestones as crews advance the 240-room tower and related amenities toward their eventual completion.
