Casa Grande, AZ Solar Energy: Panel Permits (2026)

Casa Grande's zoning code lists solar-energy collectors and their mounting or operating equipment among the structures exempt from the height limitations that would otherwise apply in a given zoning district, Municipal Code § 17.52.250(A)(6). That exemption means an installer applying for a Planning and Development building permit for rooftop or ground-mounted panels does not need a height variance or Board of Adjustment hearing solely because the array pushes above the district's stated maximum, the same treatment the subsection gives to a monument, chimney or parapet wall.

Properties inside the city's designated historic district get a second layer of review. Section 17.62.120(B)(3)(f) lists 'Solar panels' among the exterior alterations to a contributing or landmark property that count as minor work, eligible for the streamlined certificate of no effect rather than the full certificate of appropriateness the Historic Preservation Commission uses for major changes. Under § 17.62.125(A), the director issues that certificate if the installation is compatible with the historic character of the property and, where applicable, the surrounding district; prior unapproved alterations cannot be used to justify approval under § 17.62.125(C). Outside the historic district, no separate solar-specific permit exists beyond the standard building permit Planning and Development issues for the electrical and structural work.
