Waterloo, IA Historic Preservation: Historic-Cultural Monuments (2026)

Waterloo's Historic Preservation Commission, created by Ordinance 5057 in 2011, decides whether a building, structure, object or site becomes a designated historic landmark, historic district or preservation district. Section 9-8-2 defines a historic landmark as any property that meets one or more of the historic significance criteria and has been designated as a historic landmark by ordinance, and defines those criteria as the analytical factors covering the quality of significance in American history, architecture, archaeology, engineering, and culture where the property retains integrity of location, design, setting, materials, workmanship, feeling and association.

Section 9-8-6 sets the nomination process in motion: a property owner, the commission itself, or any other person or organization can nominate a landmark, while a historic or preservation district nomination needs the written consent of at least 25 percent of the record owners inside the proposed district. A complete nomination includes a state site inventory form, photographic documentation, scale maps of the property and its boundaries, and a statement showing which significance criteria the property meets; an incomplete filing is returned to the applicant.

The commission must hold a public hearing within 60 days of a complete nomination and issue its determination within 30 days after the hearing closes. Once a property is designated, § 9-8-7 requires the commission to review any alteration or demolition affecting it and to issue a certificate of no material effect, appropriateness, or economic hardship before the city can issue a regulated permit, though ordinary maintenance that does not change appearance is exempt.
