Historic Resources

The Gilroy area has many significant prehistoric, historic, and cultural resources. Examples of historic resources include buildings, districts, sites, and objects. Historical and archaeological resources are nonrenewable resources that often yield unique information about past societies and environments. The policies in the 2040 General Plan Natural and Cultural Resources Element strive to preserve Gilroy’s historic and cultural resources to preserve its local heritage for future generations.

Read more about Gilroy's fascinating history: The Historic Context Statement presents the history of Gilroy’s built environment from pre-history to present, identifies important themes, events, and patterns of development, and describes the different property types, styles, builders, and architects associated with these important periods and themes. 

What is the Mills Act? Property owners may be eligible for reduced property taxes through the City’s Mills Act program. The Mills Act is a state law allowing cities and property owners to enter into a contract allowing reduced property taxes in exchange for the continued preservation of the historic building and property. Property taxes are recalculated using a formula in the Mills Act and Revenue and Taxation Code further described in this background document

Mills Act Applications are accepted one time per calendar year in July. Mills Act contracts must be approved by the City Council.

Learn more about preservation best practices that can help to protect Gilroy's irreplaceable historic resources: The Secretary of Interior Standards are a series of concepts about maintaining, repairing, and replacing historic materials. The Standards offer four distinct approaches to the treatment of historic properties: 

  • Preservation places a high premium on the retention, conservation, maintenance and repair of a historic resource’s materials, features, finishes, spaces, and spatial relationships that, together, give a property its historic character.
  • Rehabilitation emphasizes the retention and repair of historic materials, but allows replacement when materials are deteriorated.  
  • Restoration focuses on the retention of materials from the most significant time in a property's history, while permitting the removal of materials from other periods.  
  • Reconstructionestablishes limited opportunities to re-create a non-surviving site, landscape, building, structure, or object in all new materials.
