If new transom glass is required, use clear glass. If repairing or replacing prism, tinted, or reflective glass, use clear glass. • Avoid adding new entrances on storefronts. If an additional door opening is required, add it on the rear facade. New entrances should have simple detailing that complements the historic entrance. Windows • Preserve and maintain historic windows and historic window openings. • Maintain the original space patterns and location of windows. • Avoid enclosing, reducing, expanding, concealing, or otherwise obscuring historic windows and transoms. • Avoid adding new windows to the front facade or readily visible facades. • If existing windows are determined to be irreparable by the HZC, design new replacement windows using historic profiles and dimensions compatible with the historic building. For early 19th century structures, six-over-six or four-over four sashes are appropriate. For late 19th century buildings, four-over-four, two-over-two, or one-over-one sash windows are recommended. For early 20th century designs, one-overone sashes should be installed. Windows should have distinct meeting rails and have the appearance of being operable. Do not install windows with snap-on mullions. • Avoid reflective glass, tinted glass, or other treatments that inhibit views into the building. This is not intended to apply to typical window treatments such as drapes or blinds. • Use window displays featuring merchandise on ground floor commercial buildings. Where display windows are used, provide at least a 3-foot deep display area.
