Solar Installation Permit in Unincorporated La Paz County, Arizona

La Paz County publishes a distinct 'Solar Installation' fee line item, separate from its general building-permit fee table, for rooftop and ground-mounted residential/commercial PV installations in unincorporated La Paz County. It also charges a discounted 50% plan-review rate for solar (vs. the standard 65% rate for commercial/residential building permits), confirmed by direct visual review of Resolution No. 2025-05, Exhibit D (Fee Schedule, effective August 6, 2025), pages 11-12. Electrical interconnection is billed additionally under the county's standard electrical utility fee, per the fee schedule's note that solar fees are 'plus the value of any utilities installed.'

Tips

  • La Paz County is one of the few jurisdictions in this corpus to publish BOTH a distinct flat/valuation-based Solar Installation fee AND a discounted (50% vs. 65%) plan-review rate specifically for solar — a genuinely favorable, verified county policy, not an inferred mechanism.
  • Remember the Solar Installation fee is explicitly 'plus the value of any utilities installed' — budget for the separate electrical trade fee (Utilities table) on top of the Solar Installation line.
  • Arizona's statewide HB2301 requires counties to offer instant/automated solar permitting by January 1, 2026 with a 2-business-day turnaround — ask La Paz County Community Development directly whether their iworq portal now qualifies, since this could significantly shorten the standard 40-105 working day general review timeline for a straightforward residential system.
