For homes with cantilevered rooms, sixty percent (60%) of the eaves length shall have a twelve inch (12") eave. The roof overhang shall be measured perpendicular to the vertical side of the dwelling. Unfinished galvanized steel or aluminum roofing shall not be permitted. These pitch and overhang provisions shall not apply to porch covers, bay windows, or similar appendages.

(i) Landscaping shall be installed in front yards between the front line of the house and the sidewalk on the entire width of the lot excluding the driveway. On corner lots, landscaping shall be installed in all areas between the sidewalk and the side of the house between the front property line and the rear property line which are visible from the public right-of-way.

Groundcover may include vegetative vines, low-spreading shrubs, or annual or perennial flowering or foliage plants. Groundcover may also include mineral or nonliving organic permeable material or nonliving organic permeable material in not more than fifty percent (50%) of the net landscaped area. Mineral groundcover may include such materials as rocks, boulders, gravel, or brick over sand. Species, size, and placement of landscape elements shall be determined by the homeowner.
(iii) Where secondary water is not available, at the time the water supply line to a house is installed, the builder shall furnish and install a stop-and-waste valve with an access sleeve and capped mainline to the surface to facilitate future sprinkler system installation. The stop-and-waste valve may also be located inside the home with a mainline extended to the exterior of the foundation wall and capped.
