DC Inventory of Historic Sites

The DC Inventory of Historic Sites is the official list of historic landmarks and historic districts in the District of Columbia. Properties listed in the Inventory are protected by the District’s historic preservation law, which promotes compatible alterations and adaptation for current use.

Find a Property Listing in the Inventory

The alphabetized print version of the Inventory allows for quick reference if you know the name of the historic landmark or district. Download a copy of the entire document if you want to use a computer search function. Download separate sections by initial letter if you want smaller documents.

New Listings

Find the most recent Inventory listings in the updates below.  New designations are also added to the complete inventory documents (posted above) as they occur.

Historical Eras and Themes

If you are interested in exploring different aspects of DC history, you can search the DC Inventory by property type or historical theme. The 2004 edition of the Inventory was organized to promote better understanding of the historical context for listings organized by era and type of property. An updated thematic version of the Inventory is now in preparation and will be released as sections are completed.
