Summary
Cryptocurrency mining rigs and server farms fall under Maricopa County's 'Data Center' zoning definition, restricting them to industrial-zoned parcels in unincorporated county land rather than allowing them anywhere by right.
DATA CENTER: A facility primarily used for the processing, management, or storage of digital information, housing computer servers, data storage equipment, and related infrastructure... For zoning purposes, the term includes facilities engaged in activities such as telecommunications and storage systems, central and graphical processing, neural networks, quantum computing, data routing, server farms, cryptocurrency mining or processing, virtual private networks, virtual servers, artificial intelligence training or processing, image processing, cloud computing, and email services.
Full Breakdown
The Maricopa County Zoning Ordinance defines 'Data Center' to expressly include cryptocurrency mining or processing alongside server farms, cloud computing and AI-training facilities (MCZO § 201). Chapter 6's zoning-use table lists 'Data Centers with compensatory power generation' under the INDUSTRIAL - GENERAL INDUSTRIAL category, meaning the county treats mining operations as an industrial land use confined to IND-zoned parcels in unincorporated territory rather than a use permitted in residential, agricultural or commercial districts. The county has not adopted a crypto-mining moratorium; instead it channels these facilities through ordinary industrial zoning and site-plan review, and requires on-site compensatory power generation as a listed condition of the use.
Violations & Fines
Building or operating a data-center or crypto-mining facility outside an industrial zoning district in unincorporated Maricopa County, or without required Plan of Development review, is a zoning-code violation subject to county enforcement.
