Maricopa County has no moratorium, cap, or ban on data centers. The Board of Supervisors continues to approve them — including the 160-acre Project Baccara in May 2026. Arizona's 2026 pause freezes only tax incentives through 2029, not construction.
There is no data center moratorium in unincorporated Maricopa County. On May 7, 2026, the Board of Supervisors approved Project Baccara — two data centers and a gas power plant on 160 acres at Olive Avenue and Litchfield Road near Luke Air Force Base — on a 4-1 vote, over roughly 440 opposition emails. Supervisor Thomas Galvin noted the site was 'already zoned industrial.' The only statewide brake is a budget deal effective July 1, 2026 that pauses the data center transaction-privilege-tax exemption through 2029; Governor Hobbs stressed it is not a construction moratorium. New facilities may still be built and approved.
No moratorium means no moratorium-based penalties. Data centers must still meet IND-2 or IND-3 zoning, obtain building permits, and comply with Noise Ordinance P-23; zoning or permit violations trigger standard county code-enforcement action.
