(a) In general. The maximum height of all principal structures, except for single- and two-family dwellings, located in the R2B District shall be two and one-half (2.5) stories or thirty-five (35) feet in height, whichever is less. The maximum height for all single- or two-family dwellings located in the R2B District shall be two and one-half (2.5) stories or twenty-eight (28) feet, whichever is less. The highest point of the roof of a single- or two-family dwelling with a gable, hip, or gambrel roof shall not exceed thirty-three (33) feet. The maximum floor area ratio shall be as specified in Table 546-9, R2B Lot Dimension and Building Bulk Requirements.

(b)

Gross floor area computation for single- or two-family dwellings. The floor area will be counted twice for each story with a ceiling height greater than fourteen (14) feet. Gross floor area for single- or two-family dwellings shall not include the following:

(1)

Detached accessory structures.

(2)

Open porches.

(3)

The basement floor area if the finished floor of the first story is forty-two (42) inches or less from natural grade for more than fifty (50) percent of the total perimeter.

(4)

Half story floor area.

(c)

Floor area ratio increase. Notwithstanding the floor area ratio limitations of this chapter, the maximum floor area ratio may be increased as follows:

(1)

The maximum floor area ratio of single- and two-family dwellings may be increased when the established floor area ratio of a minimum of fifty (50) percent of the single- and two-family dwellings within one hundred (100) feet of the subject site exceed the maximum floor area ratio. When floor area ratio is increased through this method, the floor area ratio shall not exceed the maximum floor area ratio of the largest single- and two-family dwelling within the one hundred (100) foot radius.

(2)

Single- and two-family dwellings existing on January 1, 2008, that exceed the maximum floor area ratio, or building additions that would cause the building to exceed the maximum floor area ratio, may increase the gross floor area one (1) time by no more than five hundred (500) square feet.

(d)

Height increase. Notwithstanding the height limitations of this chapter, the maximum height of single- and two-family dwellings may be increased to thirty-five (35) feet when the established height of a minimum of fifty (50) percent of the single- and two-family dwellings within one hundred (100) feet of the subject site exceed the maximum height. The highest point of a gable, hip, or gambrel roof shall not exceed forty (40) feet.
