Casa Grande, AZ Historic Preservation: Historic-Cultural Monuments (2026)

Casa Grande's Planning and Development Department staffs the Historic Preservation Commission (HPC), which administers Chapter 17.62 of the zoning code. The HPC may recommend that the city council designate an individual property, sign, structure or object as a landmark if it has special historic, architectural, cultural or social significance, or that a group of properties become a historic district; a landmark designation requires the property owner's concurrence, and a district requires agreement from the owners of more than half the affected property. The HPC holds a public hearing, mailing notice to owners within 300 feet of the site at least 15 days ahead, then forwards a recommendation to the city council, which holds its own hearing before approving, conditioning, postponing for up to 75 days under § 17.62.070, or denying.

An approved designation is adopted by council ordinance and recorded with the Pinal County recorder's office, revising the official landmark or historic district map. Once a property carries landmark or contributing-property status, § 17.62.100 requires the owner to obtain a certificate of no effect from the Planning and Development Department, or a certificate of appropriateness from the HPC, before any exterior alteration, restoration, reconstruction, demolition, new construction or move, or any material change to windows, doors, roofs, signs, fences, steps or paving visible from a public street.

Non-contributing properties within a district need only a certificate of no effect before repainting the exterior. The certificate requirement runs alongside, not in place of, any other city permit, and does not stop the city from pursuing its own Title 8 property-abatement remedies. De-listing a landmark or eliminating a district follows a parallel HPC recommendation and council decision when the property no longer meets the designation criteria.
