B.
In any district which requires a minimum floor area for a principal building, if such building has an attached garage a portion of the garage area may be credited toward meeting the required minimum floor area; provided, however, that neither carports nor garages built at a basement level shall be so credited.
[Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II)]
C.
In the case of any residential building which has more than a single floor level, the total of all livable floor area which is not over any other livable floor area shall be called the first floor area and shall conform to the required minimum total floor area, except that the required first floor area may be reduced to any further minimum as established and in proportion to an increase in total livable floor area as set forth in the individual district regulations.

The individual district regulations may allow that a percentage of any such increase in total livable floor area may be unfinished floor space capable under the Building Code or this chapter below of being finished to livable floor area, provided that such unfinished area is in the second story of a two-story home as defined on the Regulations Chart (see Article XXXIV).
