For purposes of this Part, "exterior features" include the architectural style, general design, and general arrangement of the exterior of a building or other structure, including the kind and texture of the building material, the size and scale of the building, and the type and style of all windows, doors, light fixtures, signs, and other appurtenant fixtures. In the case of outdoor advertising signs, "exterior features" mean the style, material, size, and location of all such signs. Such "exterior features" may, in the discretion of the local governing board, include historic signs, color, and significant landscape, archaeological, and natural features of the area.
Except as provided in subsection (b) of this section, the commission has no jurisdiction over interior arrangement. The commission shall take no action under this section except to prevent the construction, reconstruction, alteration, restoration, moving, or demolition of buildings, structures, appurtenant fixtures, outdoor advertising signs, or other significant features in the district that would be incongruous with the special character of the landmark or district. In making decisions on certificates of appropriateness, the commission shall apply the rules and standards adopted pursuant to subsection (c) of this section.
