In S Districts, no building or other structure or land shall be used and no building or other structure shall be built, altered or erected for any purpose other than of:

Prohibited uses. Any use not specifically permitted shall be prohibited.

Area per dwelling unit and lot dimensions. The minimum land area or lot size per dwelling shall be 15,000 square feet and the minimum width of the lot at the front building line shall be 100 feet. However, this shall not apply to prevent the construction of a one-family dwelling on a lot existing prior to the date of enactment and not adjoined at the side by other unoccupied land in the same ownership having an area of less than 15,000 square feet, provided that the front, rear and side setback requirements specified below are met.

Front setbacks. No building or part of a building other than steps, open porches, eaves and cornices and similar fixtures shall extend nearer the street line than the average distance of the setback of the nearest main building within 100 feet on each side of said building and fronting the same side of the street. When only one building exists on the same side of the street with the building to be erected and within 100 feet thereof, the building setback from the street line shall be not less than the average between the setback of the existing building and 50 feet. When no building exists on the same side the street with the building to be erected within 100 feet thereof, the setback at the front shall be 50 feet from the street line or 75 feet from the center line of the street, whichever requires the greater setback from the street line. However, the above shall not apply to require placing a building more than 10 feet back of the front main wall of an existing adjacent building within 100 feet thereof.

Rear setbacks. There shall be a rear yard with a depth of not less than 25 feet. When a building or property extends through a block from street to street, the front setback requirements shall be observed on both streets.

Side setbacks. There shall be two side setbacks with a total width of not less than 30 feet, and the width of the narrower of the two side setbacks shall not be less than 10 feet.

Corner lots. In the case of a corner lot, both setbacks abutting streets shall be determined as provided in § 185-11B. The minimum width of the lot at the building line parallel to the street considered to be the front street shall be 130 feet.

Height. No structure shall exceed the height of two stories.

Parking for automobiles shall be provided as required by § 185-74.

No detached private garage or other accessory building shall be placed closer to a side or rear property line than 10 feet, and for each foot the height of such building exceeds 15 feet, the offset from the rear and side property line shall be increased by one foot. No detached garage or other accessory building shall be placed closer to the street line than 10 feet to the rear of the rear main wall of the principal building, and on a corner lot, closer to the street line of the side street than 50 feet, or 1/2 the width of the lot, whichever is the lesser. In relation to an attached garage or carport built as a structural part of a dwelling, with or without breezeway connection, the same front and side setbacks shall be required as for a dwelling, and such setbacks shall be measured from the outer walls or roofline of such attached garage or carport. An attached garage or carport may extend into a rear yard.

No garage or other accessory building shall be used as a dwelling.
