Full Breakdown
CDC § 12.21.140.F lists household energy production facilities, solar and wind systems serving the property, as an accessory use permitted by right in Hillsboro's residential zones, contingent only on the necessary federal, state and local permits (building and electrical). Under CDC § 12.50.140.D, photovoltaic equipment is also exempt from the base zone's maximum building-height standard citywide; the one carve-out is the Urban Center zones, where solar equipment can project no more than 36 inches above the applicable height limit. No Conditional Use or Variance review applies to a standard home solar installation.
Violations & Fines
Installing solar equipment without the required building and electrical permits, or exceeding the 36-inch height allowance in an Urban Center zone, is a Development Code violation subject to standard permit-enforcement action.
