[2] The registries prepared by the different governments and international organizations (such as UNESCO or the European Union) are usually developed within the framework of very detailed legislation, which contemplates the relations between public authorities, conservation entities (institutional or private), the owners of the properties (in the cases of private property) and citizen collaboration.
In almost all cases, reform and renovation works on the property (both internal and external) that are not part of the rehabilitation and recovery of historical elements are strictly prohibited.
House museums are common, being former homes of famous people (artists, pioneers, soldiers, politicians, businessmen, etc.)

In addition, all sites must first be approved by the National Park Service and its special advisory board, as well as the Secretary of the Interior, before being officially registered.
