The National Register of Historic Places functions as the keystone of the nationwide movement to preserve our historic resources. Properties listed on the National Register have significance in American history, architecture, engineering, archeology, and culture. Owners who rehabilitate income- producing National Register properties are eligible for special tax incentives. In addition, listed properties are protected by an environmental review process if a federal undertaking is involved.

Anyone may submit forms documenting a property's significance and request that the property be nominated to the National Register. The California Office of Historic Preservation provides forms and guidelines, advises people preparing nominations, and presents the completed applications to the State Historical Resources Commission, the state-level review body in the nomination process. The SHPO is responsible for considering the Commission's recommendations and forwarding nominations to the United States Department of Interior in Washington, D. C., for inclusion on the National Register.
