Yuma, AZ Historic Preservation: Historic-Cultural Monuments (2026)

09(B) gives the Commission 90 days from filing to hold a public hearing and decide, unless both sides agree to an extension. Notice runs at least 15 days ahead: published once in a paper of general circulation (or posted in ten public places if there is none), and mailed to every owner within 100 feet of the proposed district or site. The Commission's decision, adopting an ordinance, shrinking the proposed boundary, or denying it, goes in writing to the Planning and Zoning Commission and then to the Mayor and Council for the final call.

Any adult resident can file a written objection with the City Clerk within ten days, which forces a City Council hearing before final action. Once created, a historic site or district is marked on the official zoning map with an "H" symbol, without changing the underlying zoning or permitted uses. Ongoing protection runs through the DHRC, a five-to-seven-member board that must include an architect or design professional, a building contractor, someone with historic-preservation training, a Planning and Zoning Commission liaison, and a district resident. 04(D)(6), the Commission decides every application to demolish, remove, renovate, or alter the exterior of a historic structure or property inside a Historic District, judging new construction on size, scale, elevation, design, color and appearance for compatibility.

A denial blocks the work entirely unless it is appealed and overturned by a superior authority. Minor maintenance, like reroofing with dimensional shingles, resurfacing a flat roof, restaining, or replacing an HVAC unit or electrical panel, can instead be approved administratively by the Zoning Administrator, with denials appealable to the DHRC.
