Historic sites and structures are recognized at the local, state, and federal level for their historical and cultural significance. Designation to an official register, or list, of resources can provide varying degrees of legal protection. Officially designated properties often become eligible for financial incentives such as tax credits and grants that can help fund their restoration. Historic buildings and cultural landscapes of unique importance, such as Bostwick, are evaluated for nomination to the National Register of Historic Places. The nomination process begins with extensive documentation and research, and the application is reviewed by the State Historic Preservation Office, local officials, and the property owner. Final review and approval is conducted by the National Park Service. The National Register Nomination for Bostwick House was approved in 1975.
