Within the various use districts, as defined in Chapter 18.14, and as indicated on the official zoning map of the planning area or parts thereof, no land, building, or structure shall be used and no building or structure shall be erected, reconstructed, or structurally altered for any purpose except as allowed in the district in which the building, land, or use is located. Permitted uses in the various districts are located in Chapters 18.17 through 18.33B. No land, building, or structure which is intended to be, in whole or in part, a conditional use shall be erected or used without specific approval of the city council. The procedures outlined in Chapter 18.10 shall be used by the planning board and the city council as a guide in granting or denying approval of a conditional use. Any variance from the dimensional regulations shall require prior, specific approval of the board of adjustment as outlined in Chapter 18.09.

In the interpretation of Chapter 18.17 through Chapter 18.33, where a use is not specifically listed, its status shall, upon application, be determined by the planning board by reference to that listed use, if any, which is so like the requested use in purpose, function, character, and affect as to be substantially similar to the listed use. (Ord. 601 § 4, 1997; Ord. 523 § 1(part), 1989)
