§ 151.36 NUMBER INTERVAL DETERMINATIONS.
   (A)   Minimum frontage. Property shall be assigned on the basis of one number for each 30 foot frontage minimum along the street, except as determined appropriate by the planning staff for business districts.
   (B)   Grid lines. Grid lines, as shown on the property numbering map, shall indicate the point at which all numbers shall change to the next higher hundred number interval.
   (C)   Multiple entrances. Where any building has more than one frontage entrance, a separate number shall be assigned for each entrance that serves a separate occupant. Should two or more entrances fall within the same grid number interval, a separate number interval may be assigned if the total address numbers within the grid do not exceed the next higher hundred interval, or letter suffixes may be used.
   (D)   Main entrance. Buildings shall be assigned numbers following a sequence after the numbering interval in which the main entrance of the building falls. If the main entrance of a building falls exactly upon the line which divides one interval from the next higher interval, the number of either interval may be assigned to that entrance.
   (E)   Multiple-family dwellings. A multiple-family dwelling having only one main entrance shall be assigned only one number, and separate apartments in the building shall carry a letter designation such as A, B, C or sequential numbers such as 1, 2, 3 or 101, 102, 103, and the like.
   (F)   Rear buildings. Any building to the rear of another building fronting on a street or alley shall carry a fractional suffix number in addition to the number assigned to the building having frontage on the street.
   (G)   Maximum number of address characters. Address numbers shall not exceed eight characters and address number suffixes shall not exceed four characters.
   (H)   Duplexes, triplexes, and the like. A duplex, triplex, and the like, house having two or more front entrances shall be assigned only one number and a letter designation such as A, B or C.
