Within any Residence C District, no building, structure or premises shall be used or arranged or designed to be used in any part, except for one or more of the following specified uses:
   (a)    Any use permitted in a Residence B District.
   (b)    Hotels, dormitories, boarding houses, lodging houses and apartment or tenement houses, including accessory services therein, and funeral homes which do no ambulance work; provided, however, that such permit for a funeral home shall be issued by the Zoning Commissioner only upon direction of the Board of Appeals.
   (c)    Accessory uses customarily incidental to any of the above permitted uses but not including the conduct of a business or industry, or any driveway or walk giving access thereto.
      (1)    A private garage on the same lot, located not less than fifty feet from the front lot line, if a separate building, or in a suitable room within or attached to the dwelling to which it is accessory and in which garage no business or industry is conducted. In the case of a corner lot no wall of the garage shall be nearer a street line than the side line of the main building and it shall also be as far from the street line as the line fixed by this ordinance for buildings on adjoining lots or as near thereto as the width of the lot will permit. Garage space may be provided for two motor vehicles on any lot and garage space may be provided for each 1,000 square feet of area by which such lot area exceeds 2,000 square feet. These provisions shall apply to private stables, one horse being considered the equivalent of one motor vehicle. The above provisions shall not prevent the location of a garage within an apartment building or within a contiguous building if on the same lot and entirely underground, permitting the storage of one car for each apartment in the building.
