Special Review Situations

Some historic properties in the District of Columbia are subject to other design reviews in addition to historic preservation review. The Historic Preservation Office (HPO) and Historic Preservation Review Board (HPRB) do not conduct these other reviews, but coordinate with the review bodies as needed.

Historic Preservation Easements

More than 1,700 historic properties in the District of Columbia are protected by private historic preservation easements and registered with the District government. By law, the easement holder must give written consent to a project before HPO and HPRB can review and clear the permit application for the work.
