All rooftop utilities or other equipment should be concealed
from view of pedestrians, car traffic and existing residential units
which may be located at higher elevations on adjacent lots. Mansard
or gabled roofs are generally preferred for detached structures. Flat
roofs should have a parapet cap and cornice appropriate to the architectural
style of the building. More ornamental architectural details such
as dentils, corbels and an ornamental frieze are encouraged and may
exceed the maximum height requirement.
If feasible, all original windows shall be maintained and remain
uncovered; this should include transoms often found above doorways
in many buildings. Replacement windows shall have similar features
as the originals and shall be appropriate to the architectural style
of the building. Maintaining architectural style may also include
retention of decorative features surrounding windows such as sills,
lintels, shutters or other elements. Windows that are different sizes
from the original and require facade modification are discouraged.
