The following considerations apply when determining whether a property meets the definition of a contributing building, structure, or site:
A building, structure, or site may also be determined contributing if it independently meets the criteria for listing in the D.C. Inventory or National Register.
For some historic districts, contributing buildings have been specifically identified at the time of designation. However, the district may include buildings, structures, or sites that have achieved significance since the time of the district's designation. A building constructed in accordance with an approval under the Act may be compatible with a district, but is not a contributing building unless the Board has determined that it meets the criteria in this section.
The same criteria may be applied to historic landmarks.
