No building shall be erected, converted, enlarged, reconstructed or structurally altered, nor shall any building or land be used, designed or arranged for any purpose other than is permitted in the district in which the building or land is located. The Planning Commission shall, however, have the authority to consider other uses similar to those permitted by right in any zoning district when:
(a) Such use is not listed in any other classification of permitted buildings or uses;
(b) Such use is more appropriate and conforms to the basic characteristics of the district to which it is to be added than to any other district;
(c) Such use does not create dangers to health and safety and does not create offensive noise, vibration, dust, heat, smoke, odor, glare or other objectionable influences to an extent greater than normally resulting from other uses listed in the district to which it is to be added; and
(d) Such use does not create traffic to a greater extent than the other uses listed in the district to which it is to be added.
The determination as to whether a use is similar to uses permitted by right shall be considered as an expansion of the use regulations of the district and not as a variance applying to a particular situation. Any use found similar shall thereafter be included in the enumeration of uses permitted by right.
All applications for a building or use not specifically listed in any of the permitted building or use classifications in any of the districts shall be submitted to the Planning Commission and, after approval by it, confirmed by Council resolution.
