What can Pima County require of a project?
Arizona has no state siting permit for solar, wind, or battery plants and no state decommissioning law, so Pima County's own zoning sets most of the rules; a transmission line of 115 kV or more needs a state certificate (state rules).
County rules and recent actions: Solar farms are allowed by right in the county's Renewable Energy Incentive District and as a Type II conditional use in the RH zone outside it. (Pima County hearing administrator memo, 2024)
