The National Register of Historic Places (NRHP) is the United States federal government's official list of districts, sites, buildings, structures, and objects deemed worthy of preservation for their historical significance or "great artistic value". A property listed in the National Register, or located within a National Register Historic District, may qualify for tax incentives derived from the total value of expenses incurred in preserving the property.

Historic districts in the United States are designated historic districts recognizing a group of buildings, archaeological resources, or other properties as historically or architecturally significant. Buildings, structures, objects, and sites within a historic district are normally divided into two categories, contributing and non-contributing. Districts vary greatly in size and composition: a historic district could comprise an entire neighborhood with hundreds of buildings, or a smaller area with just one or a few resources.
