    File: Historic Pima Count CourthouseThe Board of Supervisors on April 17 changed Pima County’s zoning code to add a new category of historic overlay zone. The “Historic Landmark Zone” designation applies to individual parcels that contain historic sites, buildings, structures, and other cultural properties that are listed, or determined eligible for listing, in the National and State Registers of Historic Places. 

    The code previously only granted "Historic Zone" designations to larger areas of contiguous properties that could encompass entire neighborhoods or districts. Those areas now will bear the designation of  ”Historic District Zone.”

    The two types of zones do not change the underlying zoning for the property but add a “historic property overlay” designation that could affect how the property is treated in the future including requests to add additional buildings and structures, modify, alter, or demolish the historic buildings and structures on that parcel.  

    “This new category will give individual property owners who wish to preserve the historical integrity of their property the ability to voluntarily apply the historic landmark zone to their property,” said Sustainability and Conservation Director Linda Mayro. “This will provide more flexibility in preserving important historic sites in the County and enhance the range of opportunities available to the public to protect historic sites and resources that are also important to the community.”

    As with all historic rezonings, review of applications for a historic overlay falls to the County’s Planning and Zoning Commission and the Tucson-Pima County Historical Commission before being submitted for approval to the Board of Supervisors. The Development Services Department and Office of Sustainability and Conservation will oversee the staff and public review processes, including public hearings to assess whether a proposed site merits historic designation as a landmark. Any future site plans would also be subject to review to ensure the historic characteristics of the site are maintained.
