The Maricopa County Stadium District owns Chase Field, while the Arizona Diamondbacks operate and maintain it under a 2018 agreement that runs through the 2027 season. A 2025 state law created a new mechanism redirecting taxes generated at the ballpark into a renovation fund governed by a new board. The Diamondbacks say lease negotiations are making little progress while the stadium faces an estimated $600 million in repairs, including roughly $80 million described as urgent. Because the new tax-backed renovation money depends in practice on a durable operating arrangement, the lease determines how public funding, team obligations, maintenance and long-term use of a county-owned asset fit together. Keeping a major league stadium functional has real economic value, but a long lease is when the public can define who pays, who maintains the building and what happens when costs exceed projections.
