Parcel Lot Points: Historic Unsubdivided Land Parcels in Washington D.C.

Parcel lot points represent lands within the District of Columbia that have never been subdivided into Record or Tax Lots. The dataset tracks parcels established by an Act of Congress in 1905, primarily covering the old 'County of Washington' north of Florida Ave and east of the Anacostia River. It is provided by the District of Columbia government and was last updated in March 2026.
