1. Building Lines on Approved Plats. Whenever the plat of a land subdivision approved by the Planning Commission and on record in the office of the County Recorder shows a building line along and frontage for the purpose of creating a front yard or side street yard line, the building line thus shown shall apply along such frontage in place of any other yard line required in this chapter.
2. Structures to Have Access. Every building hereafter erected or moved shall be on a lot adjacent to a public street or with access to an approved private street, and all structures shall be located on lots so as to provide safe and convenient access for servicing, fire protection, and required off-street parking.
3. Erection of More Than One Principal Structure on a Lot. In any district, more than one structure, housing a permitted or permissible principal use, may be erected on a single lot, provided that yard and other requirements of this chapter shall be met for each structure as though it were on an individual lot.
4. Accessory Buildings. No accessory building shall be erected in any required front yard, and no separate accessory building shall be erected within 10 feet of a main building. No accessory building shall be closer than five feet to the rear or side lot line except that where a garage is entered perpendicular or near perpendicular directly from an alley, the setback shall be 15 feet. Accessory buildings located in the rear yard may not occupy more than 35 percent of the rear yard and the aggregate of all accessory buildings shall not exceed 750 square feet. No accessory building shall be used without occupancy of the principal building, and no accessory building shall exceed 18 feet in average height. Garages are limited to 1,200 square feet for lot size of less than one acre and 2,400 square feet for lot size of one acre or more and may not occupy more than 35 percent of the rear yard and the aggregate of all other accessory buildings. (See definition of private garage.)
5. Driveways and Parking Spaces. In no case shall driveways or vehicular parking spaces be placed in any side yard unless those spaces are constructed so as not to allow drainage onto any adjacent lot.

Chimneys, church steeples, cooling towers, elevator bulkheads, fire towers, monuments, stacks, stage towers or scenery lofts, tanks, water towers, ornamental towers, spires, grain elevators, or necessary mechanical appurtenances are all special exceptions and may be approved or denied by the Board of Adjustment.
8. Projections. Sills, belt courses, cornices, and ornamental features may project only two feet into a required yard.
9. Fire Escapes and Balconies. Open fire escapes, fireproof outside stairways and balconies opening upon fire towers, and the ordinary projections of chimneys and flues into a rear yard for a distance of not more than three and one-half feet, when so placed as not to obstruct light and ventilation, may be permitted by the Zoning/Building Administrator.
10. Decks and Porches. Open, unenclosed decks or porches may extend 10 feet into a front yard and open, unenclosed decks may extend 10 feet into the back yard.
11. Terraces. Terraces that do not extend above the level of the ground (first) floor may project into a required yard, provided these projections are distant at least two feet from the adjacent side lot line.
12. Utility Service Lines. Nothing in this chapter shall have the effect of prohibiting utility service lines.
13. Paving in Front Yards. Not more than 30 percent of the front yard of any single-family residence shall be paved, provided that this shall not be construed to prevent a two-car driveway together with a paved apron leading to parking space located behind the minimum setback line.

Private permanent swimming pools shall only be allowed in the back yard.
