Summary
Tucson designates individually significant buildings, structures, sites, and archaeological resources as Historic Landmarks (HL) under UDC Section 5.8. An HL designation overlays the underlying zoning, and any exterior work on a designated property must clear a design review process before a permit issues.
The following standards should be considered when determining if an area shall be established as a HL or whether the boundaries of an existing HL shall be changed or dissolved. 1. A HL shall include historic sites, historic buildings, or historic structures, as defined in Section 11.4.9, Definitions, and which are individually listed or individually eligible for listing in the National Register of Historic Places at the local, state, or national level of significance. 2. A HL should include a group of related sites, buildings, and structures in their original setting that contribute to an understanding of the heritage of the community.

Full Breakdown

B). 6 requires a map of the proposed boundaries, a summary of the historic resources, a completed National Register nomination or State of Arizona Historic Property Inventory Form, and photographs and Statements of Significance and Integrity; City Historic Preservation Office and PDSD staff have 14 days to accept or reject the nomination for review by the Tucson-Pima County Historical Commission Plans Review Subcommittee.
5, and the Mayor and Council's final decision on the change of zoning may classify buildings, structures, or sites within the HL as Contributing, Non-Contributing, or Intrusive. 9; installation of solar panels, cisterns, or roof work qualifies for the lighter Minor HPZ Review Procedure instead of the Full HPZ Review Procedure. E).
Violations & Fines
Undertaking exterior alteration, new construction, demolition, or a parking lot addition on a designated Historic Landmark without the required PDSD design review and approval under Section 5.8.8 is a UDC violation, enforced the same as any unpermitted development under UDC Article 10 -- civil citation and required remediation or restoration, with the PDSD Director able to require the cumulative-effect "full review" track under Section 5.8.8.B.1.c even for otherwise minor repairs. Demolition requests affecting a pending or established HL are additionally screened under Section 5.8.10's demolition review standard.
