Lehi, UT Historic Preservation: Historic-Cultural Monuments (2026)

Development Code Chapter 07 defines a Landmark Site as "a site included on the Lehi City Historic Places List or State or National Register of Historic Places that meets the criteria of Section 07.040 of this chapter," adding that such sites "impart high artistic, historic, or cultural values" (Section 07.020.E). To qualify, the Historic Preservation Commission must find significance in local, state, or national history, architecture, archaeology, engineering, or culture, physical integrity of location, setting, materials, workmanship, and association "as defined by the National Park Service for the National Register of Historic Places," and that the site "must be at least 50 years old or have achieved significance within the past 50 years" (Section 07.040).

Designation runs through the same procedure used to amend the Zoning Districts Map: a property owner or the Historic Preservation Commission prepares the application, the Commission reviews it against the Section 07.040 criteria, and it forwards a recommendation to the Planning Commission (Section 07.030). Once a Landmark Site is established, the City Council directs staff to mail notice to the owner and to record a "Notice of Historic Designation" against the property's title (Section 07.060). After that, "no alteration in the exterior appearance of a structure, site, or object affecting any property" designated a Landmark Site may proceed "until an application for a Certificate of Appropriateness has been submitted to, approved, and issued by the Historic Preservation Commission," covering everything from new construction and accessory structures to signage, masonry work, fencing, and demolition (Section 07.080.A). Parks that receive the overlay are exempt unless an applicant tries to convert the park to another use (Section 07.080.B).
