San Diego County - Solar Zoning Regulations

The County of San Diego has established zoning guidelines for solar electric systems of varying sizes in the unincorporated areas of San Diego County. Photovoltaic (PV) systems which have their electricity consumed onsite are considered an accessory use in all zone types and are generally permitted as long as they meet the height and setback requirements. PV systems which generate power for offsite use and are located on parcels of land not larger than 10 acres may be allowed with an Administrative Permit in all zones. Applicable projects must follow the Administrative Permit Procedure and meet certain PV-specific requirements before an Administrative Permit may be issued. All offsite solar projects on land larger than 10 acres are considered a Major Impact Service and Utility in all zones and will require a Major Use Permit.
