Historic Districts in The United States - Federal-level

Federal-level

A listing on the National Register of Historic Places is governmental acknowledgment of a historic district. However, the Register is "an honorary status with some federal financial incentives." The National Register of Historic Places defines a historic district per U.S. federal law, last revised in 2004. According to the Register definition a historic district is:

"a geographically definable area, urban or rural, possessing a significant concentration, linkage, or continuity of sites, buildings, structures, or objects united by past events or aesthetically by plan or physical development. A district may also comprise individual elements separated geographically but linked by association or history."

Districts established under U.S. federal guidelines generally begin the process of designation through a nomination to the National Register of Historic Places. The National Register is the official recognition by the U.S. government of cultural resources worthy of preservation. While designation through the National Register does offer a district or property some protections, it is only in cases where the threatening action involves the federal government. If the federal government is not involved, then the listing on the National Register provides the site, property or district no protections. For example, if company A wants to tear down the hypothetical Smith House and company A is under contract with the state government of Illinois, then the federal designation would offer no protections. If, however, company A was under federal contract the Smith House would be protected. A federal designation is little more than recognition by the government that the resource is worthy of preservation.

In general, the criteria for acceptance to the National Register are applied consistently, but there are considerations for exceptions to the criteria and historic districts have influence on some of those exceptions. Usually, the National Register does not list religious structures, moved structures, reconstructed structures, or properties that have achieved significance within the last 50 years. However, if a property falls into one of those categories and are "integral parts of districts that do meet the criteria" then an exception allowing their listing will be made. Historic district listings, like all National Register nominations, can be rejected on the basis of owner disapproval. In the case of historic districts, a majority of owners must object in order to nullify a nomination to the National Register of Historic Places. If such an objection occurred, then the nomination would become a determination of National Register eligibility only.
