Lot area shall include all of that area of a lot which is within the definition of "lot" as set forth in §
163-5, exclusive of open spaces as set forth in said subsection. Gross floor area shall not include the following improvements and structures which shall be exempt from inclusion in the calculation of gross floor area: unroofed decks, unroofed patios, open terraces as set forth above in this section, sports courts, tennis courts, pickleball courts, padel courts, unroofed and unenclosed swimming pools, unroofed and unenclosed porches, basements and cellars to the extent the exterior exposed wall or walls thereof are four feet or less above natural grade (or four feet or less above base flood elevation where the premises are regulated under Chapter
85 of the Village Code) after construction and attics. In determining maximum lot coverage, whether under FAR or the percentage of lot coverage allowances otherwise provided above in this section or under any standard or guideline in §
163-66, the most restrictive standard shall in all events prevail. In no event shall gross floor area of any house, measured as the sum of the gross floor area of all floors of a structure measured to the exterior of the outside walls including all accessory structures except as exempted hereinabove, exceed 15,000 square feet of gross floor area. In calculating gross floor area: i) any interior space with a floor to ceiling height in excess of 15 feet shall be counted twice; ii) any first floor space used for the placement and location of mechanical (heating, ventilation, air conditioning, water pumps, and the like) systems, not in excess of 200 square feet, shall not be counted at all, provided said residence is prohibited by regulatory provision or local flooding conditions from placement of the same systems below the first floor; and iii) space improved with roofed but unenclosed and unscreened porches and/or an attached or accessory detached garage or other roofed accessory structures shall not be counted to the extent same are equal to or are less than an area which is 15% of gross floor area otherwise allowed (but in no event less than 400 square feet) or, by way of illustration, if the lot area is 72,360 square feet, then the maximum gross floor area is 6,618 square feet (72,360 minus 40,000 equals 32,360 times 0.050 equaling 1,618 plus 5,000 or 6,618 square feet) allowing up to 993 square feet (15% of 6,618 equals 993) of roofed but unenclosed and unscreened porches and/or an accessory garage or other roofed accessory structure in addition to 6,618 square feet maximum gross floor area otherwise allowed.
