Do I need a permit for solar panel installation in Tempe?
Yes. In Arizona, solar panel installation generally requires a permit, and Tempe is no exception.
Many Arizona jurisdictions (including Phoenix and Tucson) offer instant permitting through SolarAPP+ for eligible single-family and duplex roof-mount systems, but projects in flood, hillside, or historic zones must go through traditional review. A separate fire department permit and utility interconnection approval may apply; confirm both with the local building department. Tempe accepts SolarAPP+ approved designs for eligible single-family and duplex rooftop PV and residential energy storage, with code-compliant applications receiving a permit instantly; a Building Permit still has to be pulled through the Tempe Citizen Access Portal. SolarAPP+ eligibility is limited: an Arizona licensed contractor, rooftop installations only (no ground-mounted or ballasted systems), 400-amp maximum single-phase service, and NOT within the Historic Preservation district or a FEMA Special Flood Hazard Area, otherwise the project goes through standard plan review. Tempe holds a SolSmart Silver designation and publishes a solar-permit dashboard, but confirm current eligibility and technical limits on the city's Residential Photovoltaic page before applying.
