The District of Columbia State Historic Preservation Office (Historic Preservation Office) reviews cell phone installations under two authorities:

• As the State Historic Preservation Office (SHPO) with responsibility for Section 106 review under federal law; and
• As the staff to the Historic Preservation Review Board (HPRB), with responsibility for reviewing building permit applications under the D.C. historic preservation law.

The HPO goal is to streamline the review of cell phone installations by coordinating the reviews under federal and local law.

The attached document outlines the review process, submission guidance, and process timeline.
