Front yard: Twenty feet (20').
Except: Front yards shall be not less than twenty feet (20'), unless forty percent (40%) or more of the frontage is improved with buildings that have observed a greater or lesser depth of front yard, in which instance no new building or portion thereof shall project beyond a straight line drawn between the point closest to the front property line of the residence upon either side of the proposed structure. When measuring the required building setback from the front property line of the residence, the steps leading to a structure shall not be considered in the calculated distance from the front property line. The structures used as a point of reference must be located on the same block as the lot in question. But this regulation shall not be interpreted to require a front yard of more than fifty feet (50'), nor to permit a front yard of lesser depth than that of the nearest building on the same block. Where the street is curved, the line shall follow the curve of the street rather than a straight line. (Ord. 17-08, 7-18-2017)

   (A)   Connecting Features: Fences, walls, trellis and similar structures may be used as connecting features between single- family dwellings on adjacent lots. Garages, carports, and utility storage structures shall be permitted accessory uses; however, said structures shall not be used as connecting features.
   (B)   Obstructions Permitted In Required Side Yard: Patios, terraces, garden features and other similar elements may be permitted in the required side yard; provided, however, no structure, with the exception of fences or walls, shall be placed within any easement.
   (C)   Openings Prohibited On Zero Lot Line Side: One wall of the dwelling located on the interior side lot line shall have no windows, doors, air conditioning units, ducts, vents, apertures, or any other type of opening; provided, however, that atriums or courts shall be permitted on the zero lot line side when such court or atrium is enclosed by three (3) walls of the dwelling unit and a solid opaque wall of at least eight feet (8') in height is constructed on the zero lot line side and is constructed of the same materials as the exterior walls of the dwelling unit. Said wall of the dwelling located on the interior side lot line shall be a Class A firewall with a two (2) hour fire rating.
   (D)   Maintenance And Drainage Easements: A perpetual wall maintenance easement at least six feet (6') in width shall be provided on the lot adjacent to the zero lot line, which, with the exception of walls and/or fences, shall be kept clear of structures. Such easement shall be shown on the plat incorporated into each deed transferring title to the property. Overhanging eaves and gutters may not penetrate such easement on the adjacent lot, but the roof shall be so designed that water runoff from the dwelling constructed on the lot line is limited to such easement area. Footings for buildings, fences and walls may extend into such easement at heights no less than and at extension distances no greater than as originally constructed. (Ord. 98-10, 7-21-1998)
