Awning and Canopy Regulation

Because commercial awnings often extend into the public right-of-way, municipal building departments usually regulate their use. Regulations specify construction type (materials and dimensions of framing members, the use of flame retardant fabrics), minimum height above the sidewalk (usually between seven and ten feet), minimum distance between the projecting edge and the curb (usually between one and two feet), and maximum projection from the building wall. Such regulations are meant to ensure that awnings are securely built, do not pose a threat to pedestrians, and are not at risk from widely-loaded trucks. Lettering, color, and the relationship to adjacent awning designs may also be subject to building department review and approval.
Awning work on buildings located in historic districts will likely be reviewed by a historic district commission (HDC). HDCs may also review grant applications and recommend approvals for facade improvement programs, where such programs are in place. Though commissions look at projects on a case-by-case basis, many have established guidelines that address general issues and local concerns relating to awnings and canopies.
Often, local design guidelines are modeled upon The Secretary of the Interior's Standards and Guidelines for Rehabilitating Historic Buildings. These standards set forth principles meant to ensure that new elements are added sensitively, do not damage historic fabric, and are compatible with the historic character of the building.
