Summary
In unincorporated Maricopa County, solar panels are allowed as a by-right accessory use in every zoning district, no special use permit required, subject to development standards on height, setbacks, and lot coverage.
Renewable energy systems, other than utility-scale electrical generating stations, are allowed as an accessory use within any zoning district, subject to the provisions of Article 906.3.
Full Breakdown
Maricopa County Zoning Ordinance § 906.2.1 lets residents install rooftop or ground-mounted solar panels without applying for a special use permit: they're allowed as an accessory use in any zoning district. The panels still have to follow Article 906.3's development standards: they don't count toward lot coverage unless the panel structure itself qualifies as a building, height must stay within the district's normal limit unless the array is mounted on a building, and required setbacks are measured to the panel's closest edge rather than a support pole. Off-grid panels wired to a single fixture, like landscape lighting, are exempt from these standards entirely.
Violations & Fines
A renewable energy system left inoperable must be repaired or removed within one year at the owner's expense; unpermitted ground-mounted equipment exceeding the six-foot side-yard height limit is also a zoning violation.
