Pima County - Solar & Wind Permitting Requirements

Pima County has outlined its solar and wind permitting standards. The general requirements include a site plan and cut sheets for all system equipment. For solar photovoltaic (PV) systems a one line diagram with conductor and conduit sizes and types must be included. Click here for more information on solar PV system requirements. Solar hot water systems require a solar hot water schematic which includes the temperature relief valve. Wind energy systems are allowed one tower per residential lot.

It should be noted that depending on the project scope, your application may require prior approval from Regional Flood Control District (RFCD).
