Awnings provide weather protection and may also identify or decorate buildings. Awnings shade windows and storefronts and can shelter pedestrians, but as a secondary function, they also provide an area for identifying the name or trade of an occupant.
Awnings and their associated signage can significantly affect the appearance and architectural character of a historic building or district. Improper awning installation can also cause permanent damage to the materials and ornamentation of historic facades.
Awnings are not signs and should not be used as substitutes for effective signage or solely as branding elements.
The appropriateness of a specific awning depends in part upon the historic district, building type, or business type involved. Awning design should reflect the specific character of the affected landmark, building or district.
Historically, the retractable shed awning was the type used almost exclusively on Washington buildings. Barrel-vaulted awnings were less commonly used for arched openings, and more intricate and fancier quarter-round awnings were infrequently used.
Replication of a documented historic awning or pattern of awnings is considered an appropriate preservation treatment unless it clearly conflicts with the D.C. Building Code or the Board's design standards. Documentation of the historical appropriateness of a proposed awning or awnings may consist of early photographs, original drawings, or similar sources.
