A. An existing sign shall be brought into conformance with this chapter upon substantial change in the nature of the business it serves or if a change is made in design of the sign frame or supporting structure. A change in plastic face plate of a nonconforming sign will not require replacement of the total sign, but the new sign face shall conform as fully as possible to the standards of this chapter. Examples of substantial changes in the nature of the business are: a change from professional office such as a doctor, attorney or accountant to a retail outlet; or, a change from retail outlet to a service business such as a plumbing or auto repair shop.
B. Any sign which is structurally altered, relocated or replaced shall immediately be brought into compliance with all the provisions of this chapter, except the signs that are temporarily removed to allow remodeling of the premises and shall be allowed to be relocated upon the completion of remodeling. (Ord. 86, 12-7-1993)
