PHOENIX, Ariz. — The Arizona Diamondbacks are just one signature away from securing major funding to modernize Chase Field, their longtime downtown Phoenix home.
On Monday, the Arizona House of Representatives passed House Bill 2704 in a 35-20 vote. The legislation allows the state to recapture sales tax revenue generated in and around the stadium over the next 30 years. Those funds—up to $500 million—will be reinvested into renovations and upgrades at the retractable-roof venue.
The final step is a signature from Governor Katie Hobbs, who has expressed strong public support for the bill.
“I’m thrilled the legislature has passed a bill that will keep the Diamondbacks in Phoenix and create good-paying jobs,” Hobbs said Monday on social media. “This is a huge win for every Arizonan.”
Diamondbacks to Invest $250 Million of Team Funds
The Diamondbacks organization has committed to contributing an additional $250 million toward the project. Team president Derrick Hall emphasized the need for extensive improvements at the nearly 30-year-old ballpark.
Among the most urgent needs is the air conditioning system, which plays a critical role during Phoenix’s scorching summer months. Other planned upgrades include enhanced fan amenities and structural repairs to maintain safety and comfort.
“We are ecstatic over the legislative approval of HB2704,” Hall said in a statement. “Once signed by Governor Hobbs, we can focus on negotiating a long-term lease extension and begin modernizing this important public venue.”
Maricopa County Stadium District Owns the Facility
Chase Field, which opened in 1998, is publicly owned by the Maricopa County Stadium District. While the team operates the stadium, large-scale capital improvements require collaboration between public and private partners. The new funding mechanism is designed to avoid raising new taxes while preserving an essential downtown asset.
Next Step: Lease Extension with County
Once the bill becomes law, the Diamondbacks plan to enter discussions with the Maricopa County Board of Supervisors. The goal is a long-term lease agreement that aligns with the renovation timeline.
Supporters of the bill say it protects taxpayers, keeps jobs in the region, and ensures Chase Field remains a functional, fan-friendly venue well into the future.
