The State Historic Preservation Office (SHPO) encourages the preservation, documentation, and use of cultural resources. Idaho SHPO educates the public about the importance of Idaho’s cultural heritage. Idaho’s historic, archaeological, and cultural resources represent the physical and tangible manifestations of our history; they reflect who we were, where we came from, where we are now, and help shape our outlook for the future. By protecting, preserving, and understanding these important resources, we span the past, the present, and the future, not as separate events or periods, but as an on-going narrative. These resources provide economic, educational, and intrinsic value today and for future generations. The Idaho SHPO works to ensure the state’s historic and archaeological properties are preserved, interpreted, and reused.
The Idaho State Historic Preservation Office is staffed with historic preservation professionals who meet the Secretary of the Interior’s Historic Preservation Professional Qualification Standards. These Professional Qualification Standards set out the minimum education and experience needed to be considered a historic preservation professional. More information on the Secretary of the Interior’s Historic Preservation Professional Qualification Standards is available from the National Park Service. By employing individuals who meet these qualifications, the Idaho SHPO has ensured that its staff have the expertise to carry out its federally mandated responsibilities.

The National Historic Preservation Act requires all federal agencies to consider what effects their actions may have on historic properties, including archaeological sites and the built environment.
One of the functions of the Idaho SHPO is to maintain the state inventory of archaeological and historic sites. The inventory is comprised of sites identified through survey efforts of Federal and State agencies and Idaho cities and counties. Approximately 51,000 archaeological sites and 33,000 architectural and historical properties have been recorded.
An important federal program for encouraging private investment in historic buildings involves the tax incentives available for some owners and developers. For certain qualifying projects, the owner may claim 20% of their rehabilitation project costs as investment tax credits that can be applied to their federal income tax.
Certified Local Government (CLG) communities are those that shown a commitment to historic preservation. They have done this by adopting a local ordinance and creating a historic preservation commission. The program is a dynamic partnership between local governments, the Idaho State Historic Preservation Office (SHPO), and the National Park Service (NPS).
