Historic Property Identification

The Section 106 review process requires the agency official to identify historic properties in the area of potential effect (see 36 CFR § 800.4 and 36 CFR § 800.16). This identification effort focuses on properties that are listed in or eligible for listing in the National Register of Historic Places. The links provided here are starting points for historic property identification.

Research National Register of Historic Places listings in the National Register database. Enter the city/county and state as the most reliable search fields. Searches by property name or address may not return a match if the listing was entered differently.  Many listings are historic districts that have only one entry in the database. Consult the nomination form for the historic district to identify individual properties within a historic district. General information about the National Register of Historic Places can be found on the National Park Service website, as well as a list of National Historic Landmarks (NHLs) that require additional consultation with the Park Service in Section 106 reviews.

Below are direct links to available online inventories of the State Historic Preservation Offices (SHPOs). These sites may not be comprehensive and the degree and quality of information varies widely among the SHPOs. Local government records are another good source. Also, § 800.4 requires the agency official to consult with the SHPO and other stakeholders about other sources of historic property information.
