Arizona House approves bill to modernize Chase Field, securing long-term home for Diamondbacks

The Arizona House of Representatives on Monday passed House Bill 2704, a pivotal piece of legislation aimed at modernizing Chase Field, home of Major League Baseball’s Arizona Diamondbacks, while ensuring the team remains a fixture in downtown Phoenix.

What the bill does

  • Establishes a funding mechanism by redirecting sales taxes generated from concessions, merchandise, and other stadium transactions to a dedicated stadium improvement fund over the next 30 years.
  • Recaptures income taxes from select Diamondbacks employees into the same improvement fund.
  • Caps public investment at approximately $500 million, tied to annual inflation adjustments, to finance essential infrastructure upgrades—such as HVAC systems, electrical, plumbing, retractable roof, and scoreboard enhancements.
  • Includes a $250 million private investment commitment from the Diamondbacks, with provisions for annual reporting on how project funds are spent and what improvements are made.
  • Imposes penalties if the team vacates Chase Field early.

Business community voices support

“HB 2704 delivers a smart, sustainable funding model that upgrades a key public asset without raising taxes—and more importantly, it gives Arizona the certainty that the Diamondbacks will stay downtown for decades to come,” said Arizona Chamber of Commerce & Industry Executive Vice President Courtney Coolidge. “We’ve been clear: this legislation aligns taxpayer interests, business growth and community pride.”

In addition to the Arizona Chamber, the bill was supported by a broad coalition, including labor groups representing professional trades:

  • Arizona Beer & Wine Distributors
  • Arizona Lodging and Tourism Association
  • Arizona State Building and Construction Trades Council
  • Boilermakers Local 627
  • Carpenters Union Local 1912
  • Chandler Chamber of Commerce
  • East Valley Chambers of Commerce Alliance
  • Foundation for Blind Children
  • Gilbert Chamber of Commerce
  • Greater Phoenix Chamber of Commerce
  • Greater Phoenix Leadership Inc.
  • IBEW Local Union 640
  • International Association of Sheet Metal, Air, Rail & Transportation Workers Local 359
  • Ironworkers Local 75
  • Laborers International Union of North America Local 1184
  • Phoenix Community Alliance
  • Phoenix Raceway
  • Salt River Pima-Maricopa Indian Community
  • United Dairymen of Arizona
  • Valley Partnership
  • Visit Phoenix
  • West Valley Chamber of Commerce Alliance

Why it matters

Chase Field opened in 1998 and has never undergone a major renovation, and the aging infrastructure threatens its long term viability. The Diamondbacks have already spent millions on improvements such as a new roof and LED lighting, but a full-scale modernization requires public-private partnership through HB 2704.

Beyond infrastructure, the legislation ensures significant economic and community benefits: an estimated $5.4 billion in GDP generated over the team’s tenure, continued support for surrounding businesses and downtown tourism, and preserved charitable contributions that exceed $90 million.

Gov. Hobbs ready to sign

With the bill headed to her desk, Gov. Katie Hobbs praised the Legislature’s passage of the bill, describing the House vote as a “huge win” that protects jobs and bolsters Arizona’s economic vitality.
