In the case of a lot where the maximum gross floor area limitation calculated pursuant to Subsection A above would permit a one-family dwelling having more than 16,000 square feet of gross floor area, the maximum gross floor area limitation applicable to such lot shall be 16,000 square feet. It is the intent of this provision that, notwithstanding Subsection A above, the gross floor area of a one-family dwelling shall not exceed 16,000 square feet under any circumstance.
As used herein, the term "gross floor area" shall include the total
gross horizontal area of all floors of a dwelling measured to the
exterior of the outside walls, including the horizontal floor area
of any garage which is part of the dwelling, the horizontal floor
area of any enclosed breezeway which is part of the dwelling, and
the horizontal floor area of any enclosed porch, but excluding the
following:
The floor area of a basement or cellar shall be excluded in calculating
the gross floor area, provided that the basement or cellar has more
than 1/2 of its height (measured from floor to ceiling) below finished
grade.
The floor area of spaces with ceiling heights (measured from floor
to ceiling) of less than five feet shall be excluded in calculating
the gross floor area. The floor area of attic space (to wit, unfinished
space between the ceiling joists of the top story and the roof rafters)
shall be excluded in calculating the gross floor area.
Any floor area under the roof of a roofed porch or similar roofed
structure attached to the dwelling shall be excluded in calculating
the gross floor area, provided that the roofed porch or similar roofed
structure is not enclosed.
In the case of an oceanfront lot, the portion of the lot situate
between the ocean and the crest of the first rank of ocean beach dunes
shall be excluded in calculating the lot area of such lot for the
purpose of computing the maximum gross floor area of a one-family
dwelling on such lot.
