If a private property owner wishes to designate one or more spaces as restricted parking spaces on a portion of private property that is otherwise unrestricted as to parking, the owner must, instead of installing a sign at each entrance to the private property as provided by Section 48A-36(b) of this chapter, place a sign that prohibits unauthorized vehicles from parking in the designated spaces and that otherwise complies with Section 48A-36:
(1) at the right or left side of each entrance to the designated area or group of parking spaces located on the portion of the private property on which parking is restricted; or
(2) at the end of each restricted parking space so that the sign, the top of which may not be higher than seven feet above the ground, is in front of any vehicle that is parked in the space when the rear of the vehicle is at the entrance of the space. (Ord. Nos. 23106; 24175)
