Arizona Revised Statutes Section 9-1303 requires cities and counties to use expedited solar permitting through the SolarAPP+ platform or equivalent. Maricopa County and member cities issue most residential rooftop solar permits same-day or within five business days.
ARS 9-1303 (effective 2022) requires Arizona cities and counties to adopt automated solar permitting for residential systems under 25 kilowatts. Most jurisdictions use NREL's SolarAPP+ web tool for instant code-compliance review. Maricopa County uses an online residential solar checklist with same-day approval for compliant applications. Phoenix, Mesa, Scottsdale, Tempe, Chandler, Gilbert, and Glendale all participate in SolarAPP+ or equivalent express tracks. Permit fees are capped at $450 residential and $1,000 commercial under ARS 9-468. Inspections occur within three business days. Battery storage adds NEC 2020 Article 706 requirements but follows the same expedited path. HOAs cannot prohibit solar under ARS 33-439.
Cities failing to provide expedited permitting face civil enforcement under ARS 9-1303(F). Fee overcharges may be challenged in Superior Court. Unpermitted solar work triggers standard building code stop-work orders and fines up to $2,500.
